REGENERATION AND RECYCLING OF BITUMINOUS MIXTURES. 2. HOT IN-SITU RESTORATION OF WEARING COURSES

REGENERATION ET RECYCLAGE DES ENROBES BITUMINEUX - 2 - UNE TECHNIQUE DE RESTAURATION EN PLACE A CHAUD DES COUCHES DE ROULEMENT

Part 1 summarizes the causes of deterioration most often observed and their consequences. Taking into account conditions of operation and safety on motorways, the authors review different maintenance techniques (bituminous wearing courses, planing only, surface dressing applications) and compare them to "repaving" techniques from the point of view of costs and road operation during the conduct of the work. Part 2 describes the equipment and technique used for the hot, in-situ restoration of the a1 motorway in 1976 and 1977. The results obtained concern: temperatures and rate of progress of the work, bonding between layers, longitudinal and transverse profiles, longitudinal joints, evolution in binders and grading, state of compaction and permeability. Comments are made on the time-related behaviour (up to 20 months) and on perspectives of use for the repaving techniques. (TRRL)
