How to Go About Asphalt Construction and Repair 

When installing asphalt, it is important that you consider a lot of things, such as which service provider is best capable of handling the task. You have to find Champion asphalt installation experts who are very knowledgeable about the job and who can provide you with an experience that you expect. 

  How to Go About Asphalt Construction and Repair 

Some property owners go the extra step of providing the service contractors with written instructions to guide them with the type of asphalt that you want to be installed on your property. That way, you can determine the quality and scope of the work you want to be done. However, there are little specifications that you can provide and to do so, you have to be quite knowledgeable about the services as well.  

Tips on Planning a Structural Design 

Design plays a very crucial role in making sure that the structure of your asphalt driveway is optimally installed. It has to have sufficient strength and capacity to handle its service load requirements. This where the thickness of the pavement comes in. You have to specifically consider the traffic load and subgrade condition of the pavement. 

Preparation is as important as planning the design. The subgrade should be prepared properly as it serves as the pavement’s foundation. For starters, it must be free of vegetation and topsoil. Its shape should also match the final contours of the pavement. The pavement should be compacted very well and it should not have any soft spots. If there are soft spots detected, it should be replaced and removed using good soil or compacted aggregate. If a soft subgrade or an improperly compacted soil is used, some structural problems will show. 

Choosing the Right Thickness  

The base layer of aggregates of residential driveways is at least 6 inches thick. It is composed of crushed aggregate that is well compacted, which will sit right on top of the subgrade. Then it will be followed by two inches of HMA base and one and a halfinch of HMA surface. To achieve the right thickness of the asphalt, the layers would have to be compacted and not the loose.    

If you want a parking lot installed instead of a typical residential driveway, then you may have to further adjust the thicknesses to achieve the loading capacity and strength required. The stronger the pavement is, the better it will perform against heavy delivery trucks that would park on the area. If you expect to have heavy vehicles sitting on your pavement every so often, then you have to install a much thicker pavement.  

Installing a Drainage 

The structure of the drainage is also a very important factor to consider. Setting the drainage is important because it’s also determines how much the pavement would withstand the outdoor elements. Water that penetrates the subgrade will slowly drain or evaporate. The subgrade may even get damp or wet even if it doesn’t rain. Water can make the pavement lose it strength.  

When planning the design, be sure that you include the plan for the drainage system. You want the water to flow out of the pavement and into the street, and not towards your property or you’ll experience flooding.
