摘　　要：通过分析复合式(白+黑)路面的结构特点和力学特性,明晰了该种路面结构型式会出现反射裂缝为主的病害。依托广东省某高速公路实体工程,提出了聚酯玻纤防裂布缝铺、聚酯玻纤防裂布全路面满铺、高分子材料接缝处理和PG82热沥青封层等四种延缓反射裂缝的处治工艺。长期跟踪观测结果表明,聚酯玻纤防裂布全路面满铺效果最好,高分子材料接缝处理效果欠佳。Through analysis on the structural characteristics and mechanical characteristics of the composite(white+black)pavement,it is clear that this kind of pavement structure type will have diseases mainly caused by reflection cracks.Relying on an expressway entity project in Guangdong Province,four types of anti-reflection coating including polyester fiberglass anti-cracking cloth,polyester fiberglass anti-cracking cloth pavement,polymer material joint treatment and PG82 hot asphalt seal have been proposed to delay reflection cracking.The long-term tracking observation results have shown that the polyester fiberglass anti-cracking cloth has a good effect on the whole pavement,and the joint treatment effect of polymer materials is not good.
