Method for constructing upper surface layer by using high-content rubber powder asphalt concrete
The invention discloses a method for constructing an upper surface layer by using high-content rubber powder asphalt concrete, the upper surface layer comprises a lower bearing layer and an upper sealing layer, and the method comprises the following steps: laying the lower bearing layer, and carrying out leveling treatment; preparing rubber modified asphalt for laying an upper sealing layer by using an intermittent mixer; asphalt upper sealing layer construction is carried out on the upper surface of the leveled lower bearing layer through rubber modified asphalt, and the construction process of the upper sealing layer comprises the following steps that an upper sealing layer is primarily pressed, specifically, a double-steel-wheel road roller is adopted, primary pressing is carried out in a following type rolling mode, and the temperature is not lower than 165 DEG C; the upper sealing layer is re-pressed, specifically, re-pressing is conducted after initial pressing, strong vibration rolling is conducted three times through a double-steel-wheel road roller, then rolling is conducted three times through a rubber-wheel road roller, and the compaction temperature of strong vibration rolling is not lower than 150 DEG C; performing final pressing on an upper sealing layer, namely performing final pressing by rolling twice in a static rolling manner at the temperature of not lower than 120 DEG C; traffic is open; key technical indexes and key technical control are summarized, and the method has popularization significance.
本发明公开了一种使用高掺量胶粉沥青混凝土进行上面层的施工方法，上面层包括下承层和上封层，包括以下步骤：铺设下承层，并进行平整处理；使用间歇式拌和机，制备用于铺设上封层的橡胶改性沥青；在平整后的下承层的上表面，通过橡胶改性沥青进行沥青上封层施工，上封层的施工过程包括以下步骤：上封层初压：采用双钢轮压路机，通过追随式碾压方式进行初压，温度不低于165℃；上封层复压：在初压后进行复压，先通过双钢轮压路机进行强振碾压3遍，再通过胶轮压路机进行碾压3遍，强振碾压的压实温度不低于150℃；上封层终压：采用静碾方式碾压2遍进行终压，温度不低于120℃；交通开放；本发明总结了关键技术指标及关键技术控制，具有推广意义。
