沥青混凝土路面施工接缝的处理技术

在沥青混凝土路面施工中,接缝有纵向接缝和横向接缝(工作缝)两种。如果接缝处的平整度不好,会产生下洼或凸起。或因接缝处压实度不够和结合强度不足而产生裂纹,甚至松散。接缝处施工质量不理想的现象时常见到。在用宽幅摊铺机全幅摊铺面层的情况下,虽避免了纵向接缝,但横向接缝是不可避免的,至少每天会有一条工作缝。就此,对沥青混凝土路面施工中的接缝处理技术进行讨论。

Techniques for Treating Asphalt Concrete Pavement for Construction Joint

In construction of asphalt concrete pavement there are both kinds of longitudinal and transverse joints(working joints).The hollow and or the embossment will occur if the smoothness at joint is poor.And appers the cracking,even lossing because the compactness of joint is insufficient or its bond strength is not-enough.Unideal construction quality at joint place is common.Under the circumstances of the spreader with broad amplitude spreads cover in the form of whole amplitude,the longitudinal joints are avoided but transverse ones unavoidable,at least a strip of construction joint emerges every day.Therefore,the paper makes an approach to the techniques treating the joints in construction of asphalt concrete pavement.
