利用由旧路面水泥混凝土块破碎而成的再生骨料,进行了再生修补型路用混凝土的性能试验,主要测试了其抗压强度、抗折强度、干缩变形以及抗冻性能。结果表明,所配制的再生早强型和再生快修型混凝土具有较好的力学性能和耐久性能,可用于重交通等级路面的修补。 The performance of recycled concrete for road repair was tested by using recycled aggregates broken by the old pavement cement concrete blocks. The compressive strength, flexural strength, shrinkage deformation and frost resistance were mainly tested. The results show that the prepared recycled early strength and fast recycled concrete with good mechanical properties and durability, can be used for heavy traffic pavement repair.
