Three Gray Gravel Road Performance Of Study

Through analyzing ways of proportion design about the semi-rigid basement, hi the 1 ight o f climate a nd m aterial i n t he city of PingDingShan, t his p aper r esearchs integrate road-relate performance of cement lime fly-ash gravel(CLFG),such as mechanics performance ,anti-cracking performance, wear performance and so on , then optimizing aggregate and composition of semi-rigid material. Theory and testing demonstrate that suit CLFG contains the advantage of lime fly-ash gravel(LFG) and cement fly-ash gravel(CFG).Using this suit CLFG in several highways construction, we find that these highways have good performance. Secondly, for enhancing anti-cracking of basement, we append several fibers to CLFG independently, then researching its pavement performance. Thirdly, we tender anti-cracking temperature fatigue index, using this index to judge base cracking.
