Asphalt Overlaying Technology of Old Cement Concrete Pavement

W U Heping

Abstract

Aimed at projects of asphalt overlay on urban cement concrete pavement,the mechanism of reflective cracks appearing on the asphalt overlay is analyzed.The design of overlay structure which can prevent and defer the appearance of reflective cracks is put forward.Further more,the old road reinforcement technology is discussed,which can provide reference for reconstruction of urban roads.
