辽宁省高速公路沥青路面技术方案使用效果评价

Evaluation on Using Effect of Technical Scheme for Asphalt Pavement of Expressway in Liaoning Province

为了评价辽宁省高速公路沥青路面技术方案的使用效果,对应用于辽宁省高速公路的高模量、柔性基层、泡沫沥青冷再生等技术的试验路段进行长期观测。结果表明:高模量沥青混凝土技术可有效提高高温重载路段的抗车辙能力,是治理车辙问题的有效技术方案之一;柔性基层技术体现了较好的横向裂缝抑制能力;泡沫沥青冷再生技术在高速公路的实际应用效果距预想状态存在差距,应进一步加强其适用性和质量保证措施研究。

In order to evaluate the using effect of the technical scheme for the asphalt pavement of expressway in Liaoning province, the long-term observation is carried out on the test sections of expressway in Liaoning with technologies like high modulus, flexible base and cold recycling of foamed asphalt. The results show that: the high modulus asphalt concrete technology can effectively improve the rutting resistance of high temperature and heavy load sections, and it is one of the effective technical schemes for controlling the rutting problem. The flexible base technology reflects better lateral crack inhibition ability. The practical application effect of cold recycling technology of foamed asphalt on expressway is different from the expected state, and the research on its applicability and quality assurance measures should be further strengthened.
