Remember to speak to your potential customers as people. You may run a business or corporation; however, this does not mean you need to speak like one. Trust is built from personal relationships. If your potentials see you as a person who cares about their needs and how your product meets them, it will go a long way in establishing this trust.

Determine if you really want to establish a relationship with customers. Advertising through channels that are social and keeping it simplistic are the keys to driving sales. If you actually want to build a loyal customer base who repeatedly comes back and buys from you, you’ll have to begin the conversation with them by introducing yourself. Your customers will tell you want they want once you take the first step.

As was mentioned at the beginning of this article, social media marketing is a growing tend and many people are looking to leverage it in order to grow their business. However, social media can be daunting to some people who don’t know where to start. Apply this article’s advice and be on your way to using social media marketing with ease.

Geotechnical Factors That Affect the Performance of Pavement

by Posted in Concrete Services Tagged , , , ,

Pavement is designed to transfer wheel load stresses from vehicles to the subgrade. Most of the geotechnical factors that affect pavement performance relate to stiffness and strength.

Pavement

The sub-grade is the underlying ground upon which all other pavement layers will be constructed. It is the most important of all the pavement construction layers, as it is responsible for transmitting vehicular load stresses to the base course and the surface layer(s). The sub-grade should be made of a material capable of supporting the loads without causing deformation or settlement problems. This material may also need to be stabilized in order to provide a suitable foundation for the rest of the paving construction.

A capping layer is usually placed on the sub-grade if the soil is structurally weak or is expected to be subjected to exceptional loads. The capping layer is typically a selected fill material, generally a crushed rock, placed in layers no greater than 225mm thick and thoroughly compacted before placing the next layer. The engineer will determine the thickness required to adequately support the anticipated traffic loading.

Generally, the sub-grade should not contain silt or clay and be free of organic materials as these will decompose under the heavy construction loads. Sub-grade should be properly graded to ensure a smooth, level and even surface.

If the sub-grade soil has insufficient strength for the proposed traffic loads it can be improved by blending in lime or Portland cement or by treating with asphaltic binder and thorough compaction. In addition, the soil can be stabilized by incorporating a geosynthetic or other material. These products are designed to prevent moisture intrusion or expulsion and reduce swelling tendencies.

A simple way to check the moisture content bearing capacity of a soil is to squeeze it in your hand; if it stays together and has powdery texture then it is too dry and needs to be moistened, while a ball that breaks apart readily indicates that the sub-grade soil is at its optimum moisture content.

There are various laboratory tests that can be used to evaluate the strength of a sub-grade; these include the CBR test, falling weight deflectometer, and indirect shear testing. However, these are costly and labor intensive and are only able to evaluate a small sample area. For this reason, most engineers use their engineering judgment to establish limits and quantities of sub-grade stabilization based on subsurface exploration results and proof rolling evaluations.

Base Course

The base course is a layer of specified or selected material of designed thickness placed on the subgrade (or on the unbound granular base if a subbase is not used) to provide a uniform and stable support for the binder and surface courses. It typically provides a significant portion of the structural capacity in flexible pavement systems and improves foundation stiffness in rigid pavements. It also minimizes intrusion of fines from the subgrade into the pavement structure and improves drainage.

A high quality granular or crushed rock aggregate is generally used to form the base. The aggregates may be used as-is or treated with various stabilizing admixtures to increase the strength and stiffness of the base material and/or to help reduce the total pavement thickness for cost savings. For example, the base may be treated with Portland cement, asphalt emulsions, lime or flyash to increase its strength, density and/or porosity.

Whether or not the base is bound with bitumen, it must be densely compacted to achieve proper load distribution and improve drainage characteristics of the pavement. In the case of a bituminous pavement, the base may be made from either hot-paved or cold-paved asphalt (HMA). Increasingly, a percentage of recycled construction materials are being used in the production of these mixes.

In the case of a non-bituminous pavement, a mineral aggregate mixture is used for the base. This mixture can be bound with bitumen if it is heated or it can be hydraulically bound if bitumen is not used and the aggregates are mixed with cement or lime.

For cold-paved bituminous pavements, the base is usually made from a hot or cold mix of aggregate and a liquid asphalt binding agent. Typically the bituminous base mixes are comprised of aggregates from uncrushed gravel and coarse aggregate to crushed granite, recycled concrete, and/or crushed sand.

In some instances, a frost blanket is included in the base layer to insulate the base and subgrade layers from moisture action that can lead to frost damage within the pavement structure. Frost damage occurs as water within the pavement structure freezes and expands, exerting tensile stresses in the layers below it. These stresses must be relieved to avoid failure of the pavement structure.

Binder Course

A binder course is the layer that binds together aggregate and hot-mix asphalt. It is a load-bearing layer and must be strong enough to support the traffic loads for as long as several decades. The material used for the binder course varies depending on the specific use. In general, it is a mix of coarse and fine aggregates with a bituminous binder. Aggregates used for this purpose could be crushed rock, sand, gravel and/or recycled materials such as concrete, slag or reclaimed asphalt pavement (RAP). The binder is typically bitumen but in recent times other bio-based binders are also being tested.

The quality of the binder is crucial for the performance of the asphalt pavement. For this reason, shear and rut resistance testing of the asphalt binder is performed in advance of construction. This test is known as grading of asphalt binders and the results are used to establish a Performance-Graded (PG) asphalt binder specification. The shear and rut resistance tests are conducted using a rotational viscometer, COC flashpoint tester and dynamic shear and bending beam rheometers.

In addition, the PG grading system includes physical performance tests such as penetration, softening point and ductility. In order to obtain accurate shear and rut resistance results, the asphalt binder must be subjected to careful temperature control. This is because for various reasons, asphalt binders tend to harden with time.

For these reasons, this class provides the latest information about testing and grading of asphalt binders. It offers extensive hands-on lab experience that enables students to perform all required tests and make the necessary calculations. A review exam is also provided near the end of the class. This class is recommended for anyone who is responsible for asphalt testing, materials approval and specification. It is also ideal for asphalt paving contractors and engineers who want to understand the current practices in asphalt testing, grading and quality control. The course is offered in an onsite format or as an online class.

Surface Course

The top layer of the pavement structure that comes in direct contact with traffic loads, the surface course is the most critical element for a pavement to function properly. It needs to be hardy enough to resist skidding, traffic abrasion and the disintegrating effects of climate. It also needs to be tough enough to prevent distortion and prevent water from penetrating into the underlying layers.

The asphalt surface layer may be constructed in several different ways including traditional hot rolled asphalt (HMA), soft asphalt, porous asphalt or NatraTex. These materials are used in the construction of a range of infrastructure projects including footpaths, cycle paths, residential and commercial driveways and main roads.

Depending on the design of the pavement the subbase layer may be an unbound granular layer or a road asphalt base course. The function of the base course is to spread the load from the asphalt surface layer over a greater area thus reducing the overall stress on the subgrade soils and the asphalt binder layer. It also serves to minimize the intrusion of fines from the subgrade into the pavement structure and improve drainage.

The subgrade soils are under a constant amount of stress from the traffic and environmental loads, which transfer through the pavement layers. It is essential that the subgrade be well compacted to a high density and within its optimum moisture content to prevent over-stressing of the material.

Once the base and subbase courses are placed on the roadway, it is time for the paving contractor to construct the final surface course. The surfacing material of choice for most highways and major roads is HMA, sometimes known as bituminous macadam or blacktop. However, there are a wide range of alternative materials that can be used in the construction of a road or parking lot including chip seal and self-binding gravel.

The surface course is important for the durability of a pavement, and is typically constructed with aggregates that have a size distribution that will create a smooth, durable, waterproof riding surface with good skid resistance. In addition to its surface properties, the surface course is important for a pavement because it provides a strong connection between the roadbed and the traffic surface. It is also a key component in the identification of distress in a pavement, so that it can be corrected before it progresses to the underlying intermediate or binder layer.

Why Choose Asphalt Paving?

Asphalt Paving is an environmentally friendly choice. It uses less energy to produce and install, and is a more fuel efficient alternative to other materials.

Asphalt Paving

This material also helps reduce road friction, which cuts vehicle maintenance costs and lowers carbon dioxide emissions. A smoother roadway also extends its lifespan, saving taxpayer money in long run.

Asphalt paving is cheaper than concrete and can be more affordable if you add some of the available finishing options. Asphalt also takes less time to lay and is easier to maintain than concrete.

The cost of your asphalt paving is determined by the size, materials, and preparation needed to create the surface you want. A great paving contractor will make sure to provide a full estimate and warranty before beginning any work. They will also have all required licensing and insurance.

Before laying your new asphalt, the contractor will need to remove any landscaping features you have in place or existing paving material. If your home sits on a slope, the contractor may need to grade or level the area. This service is normally included with the paving job.

A new asphalt driveway can last up to 20 years if it is constructed properly and maintained regularly. However, it is important to remember that if water or gasoline are present under the surface, it can damage and shorten the lifespan of your driveway. To ensure the longevity of your pavement, it is recommended to keep up with regular maintenance and reseal the area every three to five years.

An asphalt pavement is a mixture of aggregates and binder, which bonds the hard materials together to form a solid and durable surface. The aggregates used in the mix can be crushed rock, sand, gravel or even recycled products like slags and construction and demolition debris. To bind the aggregates, bitumen is used, which can be made from natural or synthetic sources. Increasingly, waste and by-products are being used to create asphalt, which increases sustainability.

Once the asphalt mix is created it is kept hot throughout the paving process to prevent the material from drying out and cracking. The material is then loaded into dump trucks and delivered to the paving site. It is laid by a paver, which is available in wheeled and tracked versions. The paver has a hopper, feeder conveyors, distribution augers and an engine that tows a screed. The screed is what levels the asphalt and can be hydraulically adjusted to suit different applications.

It’s Durable

Asphalt surfaces are made to withstand heavy loads and the elements, lasting for decades before they require reconstruction. This durability comes from the fact that asphalt pavements can be “tailored” – appropriately formulated and designed to support the traffic load and climatic conditions of a particular road. Asphalt mixes can also be flexibly constructed to allow for thermal cycling (freezing and thawing).

Another factor that contributes to the longevity of asphalt surfaces is the elasticity of bitumen – the substance that gives asphalt its viscous nature. Unlike concrete, which can crack and crumble under the stress of repeated freeze/thaw cycles, asphalt can stretch and contract without damage. Asphalt also offers flexibility to accommodate movement of underground technical infrastructure, such as electrical and communication cables, district heating and water pipes.

The quality of the ingredients used in asphalt paving is critical to its long-life. The right combination of aggregate materials is necessary to produce an asphalt surface that will withstand the stresses and pressures of vehicle traffic and weather. Aggregates must be durable and angular, and the size of each particle needs to be carefully controlled. Moreover, the aggregates must be tested and approved against specific, rigorous standards before they can be used in an asphalt paving solution.

When constructing an asphalt pavement, the foundation layer is typically put down first. This layer is called the sub-base layer and it is usually comprised of crushed stones. It is the load-bearing layer and it must be strong enough to prevent rutting by effectively distributing traffic and environmental loading across the underlying unbound granular layers.

Once the sub-base layer is down, a binder course is laid. This layer is responsible for binding the other layers of an asphalt pavement together and it must be able to withstand high shear stresses, while at the same time providing adequate fatigue resistance.

The top layer is then placed. It is often referred to as the wearing course and it must be able to withstand the heavy vehicles and repeated impacts that are characteristic of most roads. The wearing course must also be able to withstand oxidation and weathering, and it must be able to resist the build up of water underneath the pavement that can cause heaves.

It’s Versatile

Asphalt paving is an extremely versatile construction material that can be used for many purposes. It can be used to build roads, driveways, parking lots, athletic courts, running tracks and more. Asphalt is also a very durable material and can withstand heavy traffic loads without deteriorating significantly. This durability translates into reduced maintenance costs and a long lifespan for asphalt roads and pavements.

Another benefit of asphalt is that it is less prone to cracking than other materials, such as concrete. This makes it a more cost-effective option for homeowners and businesses alike. Additionally, asphalt paving is able to be constructed quickly compared to other materials, which can help reduce the amount of time that traffic is disrupted during construction.

In addition, asphalt is much quieter than concrete and can be colored to create a variety of looks. It’s also less likely to form potholes during the winter, which can save both time and money on repairs. The smooth surface of asphalt also helps to decrease friction between tires and the road, which improves fuel efficiency.

Unlike other materials, asphalt is a mixture of different ingredients that are heated and blended together to create the final product. The most common ingredient is bitumen, which acts as a binder and unites aggregate materials such as crushed rock, sand, gravel, slags, recycled asphalt and various other types of natural or processed minerals. The different types of asphalt can be combined to create unique mixtures designed to meet the specific requirements of a paving project.

These distinct mixtures include hot mix asphalt, warm mix asphalt and cold mix asphalt. Each can be manufactured to meet a particular paving need, such as heavy traffic, weather conditions, noise reduction or waterproofing.

Warm mix asphalt is produced at a lower temperature than hot mix asphalt, which allows it to be mixed more thoroughly and applied more evenly. This process also produces fewer fumes during construction, which can be beneficial for the environment and a safer working environment for the crew.

Cold mix asphalt is produced without heating the aggregate materials, which can be useful for areas that aren’t subject to extreme temperatures. This type of asphalt isn’t suitable for high-traffic areas, however, because it can bleed and cause tracking in warm weather.

It’s Easy to Maintain

Asphalt is a durable material that can easily withstand heavy vehicle traffic and extreme weather conditions. It’s also easy to repair and maintain, making it a great choice for residential and commercial properties. It looks professional and clean, unlike some pavement options that can get stained or unattractive over time.

Before laying down the surface of an asphalt road or driveway, contractors first slope the area. This helps to prevent water from pooling in low areas. Next, a binder layer is put down. This layer is made of large aggregate mixed with oil to create a strong base for the rest of the surface.

After the binder layer is laid, a surfacing layer is placed over it. This is a mix of smaller aggregate and oil. It is then rolled and compacted to create a smooth, solid surface. Finally, the surface is cured. The curing process takes time, but once it’s finished, the asphalt is ready for use.

Aside from being cheap and durable, asphalt is also environmentally friendly. It can be recycled, which cuts down on the need for new materials and promotes sustainability. In addition, it doesn’t require as much energy to produce and transport as other paving materials, such as concrete.

One downside of asphalt is that it’s temperature sensitive. It can soften in extreme heat, which may cause ruts and bumps. However, with proper maintenance, it can be restored to a smooth, even surface.

Asphalt is a versatile material that can be made to look like bricks or stones, or it can be stained and coloured to match the surrounding environment. It’s also possible to have porous asphalt, which allows rainwater to pass through the surface into a specially prepared gravel base that can help filter it and reduce stormwater runoff.

Asphalt is an easy material to work with, so it’s not uncommon for contractors to be able to lay the whole surface of a road or parking lot while you’re at work or asleep. This can be done quickly, without disrupting traffic. It’s also much easier than other paving methods, which can lead to lengthy construction periods and traffic delays.
