Abstract In order to study the mechanical properties of cement stabilized crushed stone base in acid rain environment, this work simulates the comprehensive effects of multiple factors such as acid rain, dry-wet cycle, and repetitive load on cement stabilized crushed stone through indoor experiments, and conducts neutralization tests and microscopic tests on the specimens to reveal the strength degradation law of cement stabilized crushed stone base under different acidity, dry-wet cycle, and repetitive load times. The experimental results show that under the action of 7 cycles of wet-dry cycle, the strength of cement stabilized crushed stone specimens increases with the increase of solution acidity, and in short-term acid rain erosion tests, the degree of neutralization inside the specimens is very low. In an acid rain environment with pH=3, as the number of dry-wet cycles increases, the specimen deteriorated from the outside to the inside, resulting in a decrease in its strength; In the same acid rain environment, the combined effects both dry-wet cycle and load cycle weaken the strength of the specimen more significantly, and the order of these two cycles have different effects on the specimen. On this basis, a strength evolution model of cement stabilized crushed stone under multiple factors was established. By comparing and verifying with measured values, the model has high prediction accuracy and can be used to estimate the residual strength of cement stabilized crushed stone base in old road renovation.
