摘　　要：为了合理地评价沥青路面的施工质量,通过室内试验和现场调查研究非均匀性对沥青混合料性能的影响,论证沥青混合料抗车辙性能和沥青路面车辙病害的关系,提出沥青路面施工质量检测的新方法,并依托实体工程验证检测方法的可行性。研究结果表明:非均匀性对沥青混合料路用性能的影响较大。非均匀沥青混合料内部无法形成密实骨架结构,空隙率通常过大或过小,且混合料的强度往往不足。仅通过控制沥青混合料良好的高温稳定性,并不能保证沥青路面的抗车辙性能。利用非均匀性和抗车辙性能的施工质量检测,可有效评价沥青路面的施工质量。China’s existing construction quality detection and acceptance system for asphalt pavement is not enough to control the quality of asphalt pavement engineering effectively. To evaluate the construction quality of asphalt pavement reasonably,the influence of heterogeneity on the performance of asphalt mixture was studied by laboratory test and field investigation. The relationship between rutting resistance of asphalt mixture and rutting disease on asphalt pavement was demonstrated. The new method of construction quality detection for asphalt pavement was put forward. And the feasibility of detection method was verified by relying on entity engineering. The results show that heterogeneity significantly affects the road performance of asphalt mixture. The dense skeleton structure cannot form in non-uniform asphalt mixture, so the void ratio is usually oversized or undersize. And the strength of the mixture is often inadequate. The anti-rutting performance of asphalt pavement cannot be guaranteed only by controlling the high temperature performance of asphalt mixture in the laboratory. The construction quality detection method based on heterogeneity and rutting resistance can be used to evaluate the construction quality of asphalt pavement effectively.
