温拌沥青混合料在多年冻土地区的应用研究

青藏高原多年冻土区气候环境恶劣，海拔高，热效率低，热拌沥青混凝土路面铺筑困难。在对青藏公路多年冻土区温拌温铺沥青混凝土路面试验工程分析的基础上，认为温拌沥青混合料在多年冻土区可以成功应用，且具有节能、环保、适合低温施工等特点。但温拌温铺沥青混凝土路面在低温环境下的水稳定性和耐久性需要进一步观察研究。

Study on Application of Warm Mix Asphalt in Permafrost Region

There has bad climatic environment，high altitude and low heating efficiency in the permafrost region of Qinghai-Tibet Plateau，resulting in difficult paving on warm mix asphalt concrete road.Based on the analysis of test engineering against such pavement，warm mix asphalt could be applied successfully with the characteristics of energy saving，environmental protection and suitability of low-temperature construction；however，the water stability and durability of warm mix and warm paving asphalt concrete pavement in low-temperature environment needs to be further observed and studied.
