由于要求路面混凝土体积变形小、混凝土板的膨胀收缩小及耐磨性能好等,所以总希望尽可能地采用单位用水量小的干硬性混凝土。目前,在大规模的路面工程中,当可能采用混凝土路面铺筑机时,混凝土的塌落度可选用2.5cm,但对于配筋量多的板或用人工铺筑路面时,混凝土的塌落度则要求8

Due to the small deformation of concrete pavement, small expansion and contraction of concrete slab and good wear resistance, it is always hoped that as much as possible, the dry hard concrete with small unit water consumption will be used. At present, in large-scale pavement engineering, when the concrete pavement paving machine may be used, the concrete slump can be used 2.5cm, but for the plate with more reinforcement or artificial pavement, the concrete slump Degree requires 8
