Performance Evaluation of Pre-Cast Slabs for Contingency Rigid Airfield Pavement Damage Repair
Draw backs of cast in-place include: a) weather window essential for operations might not be available b) several days of closure. Advantages of Pre- cast include: can be completed in about 6 hours, more control on material properties of the precast concrete, texturizing the surface for tire-pavement interaction. Draw backs of Pre-cast: cost (1.6 to 4 times higher), Transportation of the panels. This study investigates the feasibility and the efficiency of using different precast concrete panel installation techniques. High density polymer (HDP) foam and flowable fill were selected as the leveling materials after literature review. The precast panels were installed using three installation techniques (conventional injection, deep injection and flowable fill) to study their impact on the performance of the repaired sections characterized by load transfer efficiency, joint stiffness and deformation energy dissipated through the pavement foundation.
