连续高温作用下沥青路面车辙治理试验研究

Experimental Study on Rutting Control of Asphalt Pavement under Continuous High Temperature

摘要:

在全球气候变暖与城市热岛效应的共同作用下，北京市高温天气频次及连续高温时长显著增加，沥青路面的高温稳定性面临严峻考验。以北京市崇文门西大街为工程背景，分别将高黏高弹聚合物改性沥青混合料和高模量沥青混合料铺筑于试验段，以验证工程应用效果。在经历了2025年夏季连续的高温作用后，试验段路面未出现明显车辙，表明2种新型抗车辙沥青混合料均具备优良的高温抗变形能力与路用性能，可有效解决连续高温条件下重载路段车辙病害频发的问题，可为同类城市道路车辙治理提供参考。

Abstract:

Under the combined effect of global warming and urban heat island effect, the frequency and duration of consecutive high-temperature weather in Beijing have increased significantly, posing a severe challenge to the high-temperature stability of asphalt pavements. Based on the engineering project of Chongwenmen West Street in Beijing, test sections are paved with high-viscosity high-elastic polymer modified asphalt mixture and high-modulus asphalt mixture respectively to verify the engineering application effects. After experiencing the consecutive high-temperature weather in the summer of 2025, no obvious rutting occurred on the test pavement. The test results show that both new anti-rutting asphalt mixtures exhibit excellent high-temperature deformation resistance and pavement performance, which can effectively solve the frequent rutting distress of heavy-duty road sections under continuous high-temperature conditions, and provide references for rutting treatment of similar urban roads.
