40-50cm ultra-large-thickness cement stabilized macadam base layer paving construction process
The invention discloses a 40-50cm ultra-large-thickness cement stabilized macadam base layer paving construction process, which specifically comprises the following steps: a mixture is mixed and transported to a paving operation road surface, the mixture is conveyed to a spiral distributing device through a scraping plate in a hopper of a large-thickness paver, the mixture is spread in the full width direction by the spiral distributing device, a height-adjustable screed plate scrapes the mixture to a to-be-paved height, and the mixture is compacted by a rammer to form a paving surface; and then a road roller meeting the large-thickness construction requirement is adopted for rolling according to the sequence of initial rolling, re-rolling and final rolling. Through the ultra-large-thickness paving construction technology, the construction quality is guaranteed, the integrity of the base layer is provided, the production efficiency is improved, the flatness of the base layer is improved, and segregation is little; and highway quality is improved, highway diseases are effectively prevented, and the service life of the highway is prolonged.
本发明公开了一种40‑50cm超大厚度水泥稳定碎石基层摊铺施工工艺，其具体过程为：将混合料经拌合运输至摊铺作业路面，经大厚度摊铺机料斗中刮料板传送到螺旋布料器，螺旋布料器将混合料沿全宽方向摊开，可调高度的熨平板将混合料刮到欲铺高度，经夯锤振实，形成铺面；再采用符合大厚度施工要求的压路机按照初压、复压、终压顺序碾压。本发明通过大厚度的摊铺施工工艺，同时保证施工质量，提供基层整体性，提高生产效率，提高基层平整度，离析少；提升公路质量，有效防止公路病害发生，增加公路使用寿命。
