Abroad in the 1930s of the last century began to try to apply the asphalt surface to improve the performance of cement concrete pavement , from the early 1970s , it was seriously composite pavement reflective cracking study , more than 30 years , for the composite reflective cracking problem of the pavement , the world has made ??a lot of research work . Relative to the status quo in terms of foreign research and application of research in this area is still in its infancy . Of old cement concrete pavement repair technology research began in the late eighties , early nineties , the focus on data collection methods , survey and measurement methods uniform requirements , based on the various sections of the corresponding conservation strengthening and reconstruction measures . In this paper, the investigation of of Henan Province composite pavement status quo , the disease causes , and Treatment Technology of Composite Pavement reflective cracking . First, the use of three-dimensional finite element method analysis of composite pavement reflection cracking composite pavement structure , asphalt overlay and sandwich physical , structural parameters of the overlay bottom stress and several composite pavement control effects of reflective cracking Treatment Measures ; based in mechanics , of composite pavement structural design methods . Secondly, the indoor simulation experiments to study the stress-absorbing layer fiber asphalt concrete Asphalt concrete measures to prevent the effectiveness of reflective cracking and technical parameters . Finally , relying on a pilot project to observe the actual effect of the program throughout Governance , to carry out the construction technology research , to be improved for the problems .
