  要:结合实体工程,研究了温拌技术在低温季节沥青路面施工中的应用,并确定了低温季节温拌改性沥青混合料各环节的施工温度。路用性能结果表明:采用“热拌温铺”技术,在气温降低10~15℃的情况下,即低温条件温拌改性沥青混合料和正常条件热拌改性沥青混合料相比,拌和与出料温度降低5~10℃,其他各环节温度总体降低20℃时,两者的路面性能相当。

Abstract: With the applied engineering, the application of warm mix asphalt technology in asphalt pavement construction at low temperature was studied, and the construction temperature of each link of warm mix asphalt mixture at the lowtemperature was determined. The results showed that warm mix asphalt mixture compare with the normal conditions of hot mix asphalt mixture, the pavement performance of hot mix asphalt and warm mix asphalt was equivalent at low temperature by the technology of "hot mix warm paving" under the condition of reducing the ambient temperature of 10~15, mixing and discharging temperature reduced 5~10 and the other links temperature reduce 20.

Keywords: warm mix asphalt mixture; low temperature; hot mix warm paving
