摘　　要：对复合式基层沥青路面在不同层间接触条件下的力学响应分布进行比较和分析,结果表明:当层间接触条件由完全光滑变为完全连续时,复合式基层沥青路面的力学响应分布发生明显变化;相比层间光滑条件,层间连续条件下复合式基层路面具有较明显的力学优势。By comparing and analyzing the distribution of mechanical response under the contact conditions between different layers of composite asphalt pavement,it is showed that when interlayer contact conditions by completely smooth become completely continuous,the composite mechanical response of asphalt pavement of the distribution change significantly;and comparing with the interlayer smooth condition,interlayer continuous conditions composite grassroots pavement has more obvious mechanical advantage.
