It proves that adding up fiber and modified asphalt in the common asphalt mixture can decrease the brittle point temperature and strength the ability of resisting cracking . fiber - reinforced asphalt concrete and glass fiber grid which has been set between the road base and overlay can delaying reflection cracking effectively 试验证明，在普通沥青混合料中加入聚酯纤维以及使用改性沥青可脆化点温度降低，增强低温抗裂性，加入goodroad聚酯纤维和在基层与面层之间铺设玻纤格栅可有效抑制反射裂缝，值得推广。
