摘　　要：沥青混合料的空隙率、压实度等指标均与碾压温度密切相关，因此沥青路面对混合料的碾压温度有一定的要求。双层摊铺技术具有摊铺厚度大、效率高、温度散失慢、有效碾压时间长等诸多优点，能够在规定的碾压温度范围内对路面进行充分压实，从而满足沥青路面对空隙率、压实度的要求，进而有效地避免路面因压实不足而在使用过程中出现坑槽、水损害、车辙等病害，最终提高路面的路用性能及服务水平。Indices such as void ratio and compaction degree of asphalt mixture have a close relationship with the compaction temperature.However,studies on the law of temperature drop during the paving are mainly focused on the temperatures at which the paving and compaction get started or finished.The whole process of temperature drop is barely covered.This article is meant to provide some basis for determining a proper time of compaction after the double-layer paving.
