Abstract
Crack repairing is considered a cost-effective technique in preventive maintenance, provided that right repairing method and material are selected and properly applied. By means of timely and effective crack repairing manners, the service life of pavement could be increased and leads to significant cost savings for the highway management system. In this study, a chemical grouting method that usually used in the repair of cement concrete structures was employed and modified for the crack repairing of asphalt concrete pavements. In order to evaluate the feasibility and effectiveness of the proposed method, in-situ experiments were performed on several typical pavement sections with all kinds of cracks. Through long-term observation and by comparison with the conventional crack repairing method, the chemical grouting method was proved effective for the crack repairing of asphalt pavements, and exhibited desirable durability under heavy traffic loads.
