PENETRATION MACADAM AS A SURFACE TO MINIMIZE THE REFLECTED CRACKS FROM SOIL CEMENT BASE

This report on the stabilization of inferior materials for road base covers cement and lime stabilization, and describes experience which indicates that penetration macadam surface can minimize cracks. Penetration macadam can also prevent failure at the crack plane due to slab pumping action, and self-sealing can be expected with the right amount of applied bitumen. Design criteria are set forth and the construction method is detailed.
