Transverse Cracking Study of Asphalt Pavement

Transverse cracking of asphalt pavements has been a problem which has been in existence since asphalt was first used as a pavement material. The suggested causes for this phenomenon consists of, but are not limited to, ambient temperature changes, temperature susceptibility of the asphalt, grade of asphalt

A moderate amount of reflective cracking was observed for the two pavement sites with full rubblization. Pavements with the rock interlayer and modified rubblization treatments had much less reflective cracking. It is recommended that use of the modified rubblization and rock interlayer treatments for reflective cracking mitigation are best. 17.

Over time, a longitudinal crack usually occurs between the asphalt mats, permitting the intrusion of water, increasing roughness, and potentially limiting the life of the pavement.

Best Practices for Crack Treatments for Asphalt Pavements

Crack sealing and crack filling are widely used treatments for maintenance of asphalt pavements. However, successful crack sealing and crack filling applications continue to be viewed as an art. When not properly applied, these pavement preservation treatments can result in early failures and costly corrective maintenance for highway agencies.

These treatments consist of applying a highly elastic material into pavement cracks to prevent or reduce the intrusion of water and incompressible materials. The benefits of crack sealing include decreasing further crack deterioration, protecting the pavement structure from moisture damage, and ultimately extending the pavement life.

Oct 10, 2014  There are a wide range of factors that contribute to pavement cracking and if left untreated, it’s going to deteriorate very fast. However, when treatment is considered, the deterioration will be slowed down or stopped completely and any subsequent surfacing treatments applied to the pavement are going to be more effective.
