An innovative technique for using polymer composites in airport pavement rehabilitation

摘要

A new design of a fiberglass composite overlay with a granite riding surface to eliminate reflective cracking on jointed rigid airport pavements is presented, together with an analytical solution for the stresses and deflection in the overlay. The stresses and deflection are obtained from fracture mechanics using the relationship between the deflection and the stress intensity factor for a crack or joint. All modes of cracking are analyzed rationally. The thermal, bending and shear stresses together with the number of cycles of repeated loading for the occurrence of the first sign of reflective cracking are presented.
