Abstract: Pervious concreteis a key material for the construction of sponge city. At present, the low strength and poor frost resistance of ordinary per-vious concrete are considered to limit its application in high-grade roads. In this work, an ultra-high strength cementitious matrix with a compressive strength of over 160 MPa was developed based on a particle packing model, which has strong film-forming ability. Its stable paste film thickness (SPFT) increases with decreasing fluidity and increasing aggregate particle size, and the relationship between SPFT and fluidity was established. Furthermore, the mix design method of high strength frost resistant pervious concrete (HSFRPC) was proposed. HSFRPC with compressive strength over 50 MPa, flexural strength over 7.5 MPa, water permeability coefficient over 4 mm/s, and frost resistance grade up to F300 was designed and produced by this method. The effects of aggregate particle size and porosity on the mechanical properties, water per-meability, and frost resistance of HSFRPC were analyzed. The properties evaluation results based on radar map show that HSFRPC with an aggregate particle size of 2.36—4.75 mm and a design porosity of 20% has excellent and balanced engineering performance, and can be referred to for road engineering in cold regions.
