Roller compacted concrete layer treatment method
The invention discloses a roller compacted concrete layer surface treatment method. The method comprises the following steps: detecting the layer surface hardness and hydration degree of a roller compacted concrete lower layer; when the surface hardness is larger than 5 mm and the hydration degree is smaller than 0.8, the surface treatment mode adopts insertion tamping and watering; when the surface hardness is not larger than 5mm and the hydration degree is not smaller than 0.8, brushing is adopted for surface treatment, water is sprayed after cleaning, and then the middle cushion layer mixture is laid. The invention provides a specific and accurate lower-layer construction surface state control method and evaluation indexes for solving the problems that the existing roller compacted concrete lower-layer construction surface state evaluation indexes are lack of scientificity and accuracy and the complexity of site construction conditions is considered, so that the layer bonding strength, stability, durability and the like are improved; the problem that an existing roller compacted concrete layer processing method is poor in scientificity, accuracy, economical efficiency and effectiveness is solved.
本发明公开了一种碾压混凝土层面处理方法,包括以下步骤:检测碾压混凝土下层的层面硬度、水化度;当层面硬度大于5mm且水化度小于0.8时,层面处理方式采用插捣、洒水;当不满足层面硬度大于5mm且水化度小于0.8时,层面处理方式采用刷毛、清洁后洒水,再铺设中间垫层拌合物。本发明针对目前碾压混凝土下层施工面状态评价指标缺科学性与准确性,以及考虑现场施工条件的复杂性,提出具体、准确的下层施工面状态控制方法与评价指标,提高了层面结合强度、稳定性和耐久性等,解决了目前碾压混凝土层面处理方法科学性、准确性、经济性、有效性差的问题。
