###### Abstract  
Construction and demolition wastes (C&DWs) have raised a large number of ecological and environmental problems. Recycling C&DWs into recycled concrete aggregate (RCA) will help save natural resources effectively and reduce the negative impact of C&DW on the environment. Innovative pervious concrete (ITC) can mitigate extreme weather disasters, such as ransiorms, and overcome the low strength and poor durability of traditional pervious concrete. In this study, innovative recycled pervious concrete (IRPC) is prepared by combining RCA with IPC, which has broad application prospects and ecological friendliness. This study investigates the effect of RCA quality grades and replacement rates on the mechanical property, permeability, sulfate resistance and abrasion resistance of IRPC. IRPC mixtures were prepared with three different quality grades (high, medium and low qualities) of aggregates named as NA, RCA\({}_{1}\) and RCA\({}_{2}\). Moreover, the replacement rate of RCA for NA varied as 0%, 25%, 50%, 75% and 100%. The IRPC specimens were tested for compressive strength, mass loss and abrasion resistance after different sulfate wetting-drying cycles of 0, 30 and 60. The results exhibited that the initial compressive strength of all types of IRPC was more than 40 MPa. The compressive strength and mass of most IRPC increased first and then decreased slightly with the passage of a number of sulfate wetting-drying cycles, indicating IRPC has good resistance to sulfate attack. Sulfate attack and the addition of RCA will reduce the abrasion resistance of IRPC. However, when the replacement rate is lower than 50%, and the RCA quality is better (attached mortar content < 25%), the abrasion resistance of IRPC will be improved under sulfate attack. The experimental results might be useful as a reference and design methodology for employing IRPC in pavement applications in the future. innovative recycled pervious concrete; recycled aggregate; quality grades of aggregate; replacement rate; abrasion resistance; sulfate attack +

development and social life [8]. Compared with traditional impervious pavement, pervious concrete pavement can reduce rainwater runoff, reduce noise, replenish groundwater, reduce the heat island effect and remove rainwater runoff pollutants [9; 10]. However, the low strength, high likelihood for clogging and poor durability of traditional pervious concrete limit its potential use in structural applications [11; 12]. In order to solve these defects, a kind of innovative pervious concrete with top-bottom interconnected pores was designed and prepared by our former research [13]. The results prove that innovative pervious concrete is superior to traditional pervious concrete in mechanical properties and frost resistance. The environmental friendliness of innovative pervious concrete can be further improved by replacing NA with RCA. However, whether it has adverse effects on mechanical properties and durability of innovative recycled pervious concrete (IRPC) remains to be studied. In general, the utilization of RCA will contribute to the degradation of mechanical properties and the durability of recycled concrete [14; 15; 16]. Replacing NA with RCA will lead to a decrease in compressive strength of the concrete, which will continue to decrease with the increase of the replacement rate of RCA [17; 18; 19]. Moreover, the quality grades of RCA, such as water absorption, crushing index and attached mortar content, play an important role in the durability of recycled concrete [20]. Furthermore, the strength and durability of recycled concrete are affected by the interfacial transition zone (ITZ), as it owns many cracks and pores, low bonding strength and high permeability [21].
