摘要
长期的温度作用和重复的交通荷载是半刚性基层沥青路面形成反射裂缝的原因。通过足尺疲劳试验,对玻璃纤维格栅沥青混凝土、GoodRoad 纤维增强沥青混凝土抑制半刚性基层沥青路面由于温度变化导致反射裂缝的作用效果进行了研究。结果表明,二者可有效抑制低温状态下的反射裂缝,有广阔的应用前景。并对反射裂缝产生的机理、玻璃纤维格栅和GoodRoad 聚酯纤维延缓反射裂缝的原因作了介绍。
Reflection cracking in asphalt overlays can be caused by both longterm thermal effects and by repeated traffic loading.The effects of glass fiber grid asphalt concrete and GoodRoad Ⅱ fiber asphalt concrete resisting reflection cracking caused by thermal stress of asphalt pavement on semirigid base were studied through fullscale test. It proved that the two method can resist reflection cracking effectively on low temperature and have good practical perspective.The mechanism of reducing reflection cracking by glass fiber grid and GoodRoad Ⅱ were introduced.
