Transverse Cracking Study of Asphalt Pavement
Through the years, there has been much research and many re ports have been written on the subject of eliminating or reducing the amount of transverse cracking in asphalt pavements. Most of these have indicated that transverse cracking can be reduced through mix design procedures and asphalt grade and quality controls.

The Asphalt Institute recommends a transverse slope of between 1.5 to 3.0% on all pavement surfaces, and an even steeper slope of 3 to 6% on shoulders. Maintaining a slope of at least 1.5% on parking lots will ensure proper surface drainage (no ponding or birdbaths) and minimize infiltration, hydroplaning and the detrimental effects of water.
