Structure stress of asphalt overlay on old cement concrete pavement

The structure stress of old cement concrete pavement with asphalt overlay was analyzed with the one of the structure withuence of traffic loads, temperature changes, and thes on the structure stress of asphalt overlay was studied. The results showte pavement without thegth of asphalt materials, growing the depth ofe modulus of bases can improve the mechanic performance of asphalty on a limited scale, and this method is not always economical and efficient . If STRATAete pavement and the load transfertaneously, the stress and strain in the asphalt overlayraffic and temperature loads can be improved significantly. 6 tabs, 6 figs,
