Abstract:

FWD deflection evaluation methods can not be applied to composite pavement grouting engineering as the asphalt concrete material modulus changes with temperature. Based on a composite pavement grouting engineering of a Shanghai 4E airport,a calculation method for load modification factor and temperature modification factor is proposed,meanwhile,a method for composite pavement grouting effect evaluation based on FWD deflection test is obtained. Engineering example shows that this method can meet the needs of composite pavement grouting effect evaluation.

Key words: composite pavement, grouting, FWD, load modification, temperature modification
