采用铺路毡料防止沥青路面反射裂缝的试验研究

The experiment research of using paving mat material to prevent reflection crack of bituminous pavement

采用土工合成材料防止反射裂缝的试验结果表明:使用铺路毡效果最好,而铺设玻璃纤维格栅由于出现粘结问题,将导致龟裂和孔洞的形成。按照法国L.R.P.C.Autun的评价体系,使用铺路毡的性价比比不用加筋材料的路面高3倍,比使用玻璃纤维格栅的高2倍,铺路毡性价比最高。

The experiment result of using geosynthetics materials to prevent reflection crack showed that the effect of using paving mat material was the best while paving the glass fiber grill may appeared bonding problem which would lead to fracturing and hole. According to the French L. R. P. C. Autun evaluation system,cost performance of paving mat is 3 times as high as that than non- reinforcement materials,2 times as high as that than glass fiber grid grill. Paving mat gets the highest cost performance. The cost performance of paving mat was the highest.
