摘要
从气象学的基本原理出发，建立了路表有效辐射的日变化过程曲线的计算方法，并与Ｂａｒｂｅｒ、严作人及舒尔茨分别给出的结构温度场计算中有效辐射的近似计算方法进行了比较，分析结果表明：正确计算路表有效辐射对准确估计沥青路面温度场有重要影响．
Based on the fundamental laws of climatology, this paper presented a computing method for the effective radiation of the surface of bituminous concrete pavement andanalysed some other approximate computing results of the effective radiation of bituminouspavement temperature field. The correct computing method played an important role in theaccurate estimation of bituminous pavement temperature field.
