ENERGY SAVING METHODS OF RESTORING PAVEMENT SURFACE CHARACTERISTICS

The need to conserve natural resources has become a major concern to highway engineers everywhere. This concern has manifested itself in several ways, one of which is the attempt to restore the functional characteristics of a pavement without consuming large amounts of additional resources such as aggregates, asphalts and fuel. This study investigated several procedures and techniques which were designed to upgrade pavements without the expenditure of large amounts of additional resources. Asphaltic pavements were recycled with both open-flame heating and radiant heating, treated with rejuvenating agents, and sprinkled with skid resistant stones. Resulting structural integrity ranged from dubious to fair. Skid resistance was generally improved but it had a tendency to quickly drop on the sections which had not been treated with skid resistant stones. The Portland cement concrete pavement test section was blasted with high pressure water sprays in an effort to improve the skid resistance. The technique proved effective but the improvement was short-lived. /Author/
