Abstract The strength and the freeze-thaw resistance of pervious concrete are key properties for its application in heavy-load traffic roads and cold regions. The workability, the strength and the interfacial adhesion of cement paste as well as the strength and the freeze-thaw resistance of pervious concrete were investigated, and the main factors affecting the performance of pervious concrete were revealed. The results show that the wor-kability of paste and pervious concrete can be evaluated by the maximum paste-aggregate ratio, and good workability of pervious concrete can be obtained when the maximum paste-aggregate ratio is close to the designed paste-aggregate ratio. The adhesive damage occurs whether freeze-thaw tests are performed on the unmodified paste or not. On the contrary, the pull-off strength of the modified paste is 67% to 156% higher than that of the unmodified paste without freeze-thaw tests, with cohesive damage occurring, while it is significantly reduced after freeze-thaw tests,with both cohesive damage and adhesive damage appearing. The compressive strength of the pervious concrete with good workability is 38.2—40.3 MPa, the flexural strength is 3.8—4.3 MPa, and the permeability coefficient is 2.85—2.92 mm/s. The results of the principal component analysis show that the principal factors on the performance of pervious concrete are in order as follows: 44.8% for interfacial properties, mix design of paste and void characteristics, 27.5% for coating properties of paste, and 20.0% for the strength of paste.
