One proven technique is using ground penetration radar (GPR), which penetrates the asphalt to reveal subsurface conditions. This method allows contractors to assess the depth and extent of damage, especially in older pavements. For instance, a study by the Transportation Research Board found that GPR effectively identified weak layers and voids beneath the surface, enabling targeted repairs. Additionally, thermal imaging cameras can highlight temperature variations, indicating potential structural issues or irregularities.
When conducting on-site assessments, asphalt contractors should follow best practices like establishing control sections to compare with damaged areas. They must also document findings using detailed reports and photographs for future reference. Resurfacing old roads is a common solution, offering both aesthetic improvements and enhanced safety. As an alternative, overlaying new material over existing asphalt can extend road life by up to 15 years. Driveway sealing best practices involve regular maintenance, typically every 2-3 years, to prevent water intrusion and aggregate loss, which are primary causes of asphalt degradation.
Repair Methods for Strengthened Road Surfaces
When it comes to repairing or replacing road surfaces that bear heavy loads, such as highways or commercial parking lots, asphalt contractors play a critical role in ensuring structural integrity and safety.
