ABSTRACT:
This is a process and composition related to recycling old asphalt pavements into new pavements. It is accomplished by adding a special asphalt emulsion to the crushed old asphaltic pavement material without requiring the addition of new aggregate or heating. The old material is cemented at the ambient temperature into a new durable composition of high stability and water resistant without rejuvenation, softening or other appreciable change in the old asphalt, such steps being eliminated by selection of the degree of hardness and character of the asphalt base stock in the special emulsion.
