ASPHALT PAVING IN 1974

This discussion of the prudent use of asphalt, reviews engineering design considerations, engineering construction methods, techniques and specifications, as well as the engineering of maintenance. Full depth asphalt pavements, planned stage construction, and soil-asphalt mixes are economical design factors. The placement of asphalt mixes in thick lifts will achieve both greater density and fewer lifts. Lower mix temperatures coupled with greater density, can produce high performance pavements. The review of specifications (to pug out mix at 250 deg F and haul it in insulated trucks) and the substitution of other asphalt products for cutback asphalts also require attention. The utilization of the correct maintenance techniques are advocated, and the areas of surface preparation treatment, surface preparation, rejuvenation and heater planning are also considered.
