在自行研发的抗冲刷试验装置基础上,运用灰色关联理论,对压实度、强度、水泥剂量、砂掺量、细石掺量和再生骨料掺量这6个因素与水泥稳定再生骨料基层混合料的抗冲刷性能进行了关联分析。结果表明:对水泥稳定再生骨料基层混合料抗冲刷性能影响最大的是压实度;强度与抗冲刷性能之间没有确定的关系;原材料组成因素中,影响最大的是水泥剂量,其次是再生骨料掺量、砂掺量,细石掺量影响很小。研究结果对水泥稳定再生骨料基层混合料的配合比设计和施工具有一定的指导意义。
On the basis of self-developed anti-erosion test device, using the gray relational theory, the factors such as compaction degree, strength, cement dosage, sand content, fine stone content and recycled aggregate content were compared with those of cement stabilized recycled aggregate The anti-erosion performance of the primary mixture was analyzed. The results show that the most important factor influencing the anti-scourability of cement-stabilized recycled aggregate is the compaction degree; there is no definite relationship between the strength and anti-scouring performance; the most influential factor is the cement dosage, followed by the regeneration Aggregate content, sand content, fine amount of fine stone little effect. The results of this study are of guiding significance for the design and construction of mixture ratio of cement stabilized recycled aggregate base course.
