摘要In this paper, the factors that affect the anti-erosion performance of three grades of cement-treated mixtures and their degree of association were studied using the Baohan highway in the Qinba mountain area, China as an engineering example. Firstly, the principal factors that affected changes in the anti-erosion performance of cement-treated mixtures and its law were analyzed with self-development model testing, which is considering changes in the aggregate's fractal dimension, compaction, cement dosage, curing age, water content, and cement strength grade in the mixtures. Secondly, the correlation coefficient between the influencing factors, scouring mass, and the predicted model for the cement-treated mixtures' scouring mass were developed according to the Grey Theory. The results showed that the mixtures' anti-erosion performance increased as cement content, strength, and curing age increased. Further, their anti-erosion performance increased firstly and then weakened with increased water content and compaction. In comparing cement-treated mixtures with suspended dense and skeleton voids, the former's scouring resistance was better. Among all these factors, the mixtures' structural type affected its erosion resistance greatly, while the cement strength grade had little effect. The cement-treated mixtures' scouring mass prediction model was established by combining material properties and external environmental factors, which can provide a reference for the design and construction of highways' base and subgrade in similar areas.
