Sectional Patching Not all projects require complete reconstruction or an overlay. Sectional patching is often a reasonable solution to extend the life of your pavement. Worst areas will be noted and addressed with a patching schedule for a cost effective solution. Removal & Replacement Eventually, asphalt reaches the end of its life cycle.
Fig.8: Longitudinal Cracks in Asphalt Flexible Pavement. Fig.9: Transverse Cracking in Asphalt Flexible Pavement. This is a fatigue cracking. Here, the cracking occurs in the direction of traffic flow. The transverse cracking is formed perpendicular to the pavement centerline. This is caused as a thermal cracking. Read More:
A pavement is usually constructed of either asphalt or portland cement concrete (PCC). An asphalt pavement is referred to as a flexible pavement, and is composed of a liquid binder in combination with coarse and fine aggregates. A flexible pavement is constructed using Hot Mix Asphalt (HMA).
Asphalt pavement absorbs more heat from the sun causing snow and ice to melt much quicker than concrete. While there are clear benefits of choosing asphalt pavement in cold climates, the opposite is true for warmer climate areas. Concrete tends to be a better material in these areas. Asphalt pavement tends to soften in extreme heat and become oily.
