HOT MIX ASPHALT FOR INTERSECTIONS IN HOT CLIMATES

2021-6-29  Rutting of hot mix asphalt (HMA) pavement at or near intersections is very common both in coldand hot climates. Obviously, the problem is more acute in hot climates compared to coldclimates because the stiffness of HMA decreases with increase in pavement temperature. In mostcases, there is no significant rutting in the same asphalt pavement structure away from theintersections under fast moving traffic. This indicates a need for a different asphalt mix
