What is the required asphalt thickness for restoring asphalt pavement after trenching?

The required asphalt thickness for restoring asphalt pavement after trenching is specified as 100 mm. This thickness is critical to ensure that the repair provides adequate structural integrity and durability.

When asphalt pavement is restored after trenching, the thickness is designed to accommodate traffic loads and environmental factors while ensuring proper compaction and bonding with the existing pavement. A thickness of 100 mm strikes the right balance between strength and flexibility, allowing the restored section to withstand the stresses of heavy vehicles and varying weather conditions. It also helps prevent issues such as cracking or rutting that can arise from insufficient thickness.

Maintaining this standard is key in ensuring that the restored pavement performs well over time and integrates seamlessly with the surrounding road surface. This depth adheres to accepted engineering practices in asphalt pavement restoration, fostering long-lasting, reliable infrastructure.
