In order to investigate the effect of water on pervious concrete pavement, The damage evolution equations of pervious concrete under three cycle modes of dry-wet, freeze-thaw, dry-wet and freeze-thaw were studied, and the damage mechanism under single and double factors were revealed. The results show that the basalt fiber changes the pore structure and initial property of pervious concrete, but does not affect the freeze-thaw damage mechanism. The exponential growth of secondary cracks caused by freeze-thaw cycle is the main reason for the difference in the evolution law of the properties of dry-wet cycle. Dry-wet in the early stage of damage causes the dissolution, loss of pore wall surface material and edge curl and peel, while freeze-thaw in the late stage of damage causes the formation and expansion of cracks, resulting in intergranular fracture. The mutual promotion of the damage caused by dry-wet and freeze-thaw cycles results in the decrease of performance indexes greater than the sum of the two.
