Having attractive Asphalt Driveways at the entrance of residential and commercial enterprises adds value to any investments. In addition, town and rural roads done with asphalt have exceptional long service life; are economical and they guarantee a smooth comfortable ride all year round.
The experience and credibility of the asphalt contractor is of paramount importance in design, laying and subsequent servicing of the driveway. Experienced and reputable Asphalt Services provider guarantees the proper preparation of materials, mixing and laying using state of the art equipment and this result to a durable, cost effective and economical driveway.
Asphalt road nature
Asphalt, concrete and sub grade are the main constituents of Asphalt driveways. Asphalt is obtained from cementite materials during petroleum processing. The concrete is made of aggregate (ballast) of different grades depending on the surface. The sub grade is the base structure that supports the pavement and act as base where load is transferred to. Other layers such as Asphalt base course (Foundation), asphalt surface course (top finish course) may be added.
Sub grade Preparation and Laying
Before laying the asphalt, the sub grade layer is first prepared. A layer of rock base materials or gravel is added depending on the load imposed on the driveway. An experienced asphalt contractor then tests the soil properties and evaluates its ability to carry load. This is followed by grading and compacting using suitable construction machines such as grader and roller. The surface is then tested to ensure right soil moisture, flatness and no deflections or depressions.
Pavement Laying and Spreading
This involves spreading and compaction of asphalt to the requisite thickness and width. The width of the pavement is determined by the type of road. Asphalt contractors have paving machines of different widths but the standard sizes range between 8 -12 feet. Full depth asphalt concrete is mostly preferred due to increased strength, resilience and ability to impede water and swelling due to freeze thaw action. The minimum thickness is 4 inches but this can be increased to 5 or 6 inches to increase strength and stability.
Spreading and compaction must be done by a qualified commercial asphalt services provider with requisite experience as this affect the performance, service life and durability. The process of heating, mixing, paving and rolling with steel wheeled rollers must be carefully controlled to ensure uniform mixing and spreading as well as compaction.
The quality of asphalt driveways is heavily dependent on the experience and expertise of the contractor. Experienced firms such as Asphalt Melbourne provide a wide range of asphalt road construction and servicing works resulting to strong, reliable and smooth public and private driveways with a long service life spanning 30 years. When done correctly, these driveways are a reliable and cost effective as compared to other construction methods such as concrete, gravel and interlocking pavers.
Asphalt roads designed with good drainage systems withstand water and freeze-thaw conditions much better than concrete and interlocking pavers. Their dark surface absorbs more heat and melts snow faster. Salting of these pavements can be done without affecting their smoothness and durability.
