Prevention of Rutting and Stripping in Asphalt Pavements
Asphalt concrete rutting, a channelized depression in the wheel paths, is the result of deformations either in the pavement or subgrade. It occurs because of consolidation or because of shear failure in the mix. Rutting can cause vehicle handling problems and it increases the potential for hydroplaning. Stripping is a form of moisture damage that can severly weaken an asphalt pavement. It can take a number of forms. Water can get between the asphalt and the aggregate and break the bond between them. Water can also get between and separate the coated particles in the mix. Still another form occurs when the asphalt cement emulsifies in water. High words or segregation can accelerate stripping by letting water into the mat. Stripping can rob a pavement of a significant portion of its life. It also contributes to early rutting because of strength loss in the stripped layer. This videocassette shows the problems and explains possible solutions to eliminate rutting and stripping of pavements.
