由于石灰石骨料混凝土路面的磨损是一个值得关注的问题，因此利用轮胎链的松散试验对可回收混凝土路面的磨损和随后的抗滑性进行了研究。可再生混凝土是用粉煤灰混凝土代替40%的水泥质量制成的。石灰石细、粗骨料混合在混凝土中，水胶比为0.33，以获得早期足够的强度。试验结果表明：(1)随着粉煤灰掺量的增加，再生混凝土的磨损逐渐增大；(2)可再生混凝土的抗滑性与含硅骨料混凝土的抗滑性几乎相等。
The abrasion and subsequent skid resistance of recyclable concrete pavement using raveling tests with tire chains has been examined, since the abrasion of limestone aggregate-containing concrete pavements is of concern. The recyclable concrete was made by replacing 40% of the cement mass with fly ash concrete. Limestone rock fine and coarse aggregates were mixed in the concrete with a water/cementitious material ratio of 0.33 for early adequate strength. The test results show: (1) the abrasion wear of the recyclable concrete increases gradually with an increase of fly ash; (2) the skid resistance of the recyclable concrete is almost equal skid resistance to the concrete with siliceous aggregate.
