Ultrathin overlay process
The invention provides an ultra-thin overlay process which comprises the following 12 construction steps: S1, technical preparation: designing a target mix proportion, a production mix proportion, production mix proportion verification and construction guidance opinions; s2, material preparation: preparing matrix asphalt, coarse aggregate, fine aggregate, mineral powder, a warm mixing agent, a high-viscosity modifier, emulsified asphalt and fibers; s3, mechanical preparation: preparing intermittent asphalt concrete mixing equipment, an asphalt mixture paver I, an asphalt mixture paver II, a double-drum vibratory roller, a pneumatic tire roller, an asphalt distribution truck and the like. The ultra-thin overlay process provided by the invention has excellent performance, does not reduce other pavement performance on the premise of ensuring better skid resistance and noise reduction performance, is low in cost, saves the raw material cost by more than 30% compared with 4cm AC-13, takes into account crack diseases, treats cracks before treating ruts, and has the advantages of short construction period, less material consumption, high paving speed, short construction period and high efficiency. And the influence on traffic volume is small.
本发明提供了一种超薄罩面工艺，包括：12个施工步骤，其中：S1、技术准备：设计目标配合比、生产配合比、生产配合比验证、施工指导意见；S2、材料准备：准备基质沥青、粗集料、细集料、矿粉、温拌剂、高黏改性剂、乳化沥青、纤维；S3、机械准备：准备间歇式沥青砼拌和设备、沥青混合料摊铺机一、沥青混合料摊铺机二、双钢轮振动压路机、轮胎压路机、沥青洒布车等。本发明提供的超薄罩面工艺，其性能优，在能够保证更好的抗滑、降噪性能的前提下，不降低其他路用性能，造价低，相对于4cmAC‑13节约原材料成本30％以上，兼顾裂缝病害，处治车辙前对裂缝进行处理，工期短，用料少、摊铺速度快，施工工期短，对交通量影响小。
