摘要

Pervious concrete (PC) pavements are gaining prominence as a sustainable alternative to traditional impermeable surfaces, offering effective stormwater management, heat island mitigation, and environmental benefits. Their high porosity facilitates rapid water infiltration, reducing surface runoff while enhancing groundwater recharge. However, achieving an optimal balance between mechanical strength, durability, and hydraulic performance remains a critical challenge. This review provides a comprehensive evaluation of the factors influencing PC performance, including mix design, carbonation effects, freeze–thaw resistance, clogging behaviour, and long-term field performances and maintenance strategies of PC pavement. Optimal PC mixtures typically incorporate aggregate sizes between 4.75 and 12 mm, an aggregate-to-binder (A/B) ratio of 2–5, and a porosity range of 18–22%, yielding compressive strengths of 20–30 MPa and flexural strengths up to 4 MPa. The inclusion of 2% steel fibers enhances structural integrity, while partial replacement of cement with 20–30% fly ash, silica fume, or slag improves durability and reduces raveling loss by 20–40%. Carbonation enhances the matrix densification and strength of PC, but requires controlled exposure to prevent C–S–H decalcification and durability loss. pavement thickness varies from 150 to 254 mm for low-traffic roads and heavy traffic areas respectively. Vibrating screeds and steel pipe rollers optimize compaction, while 6 m joint spacing minimizes cracking. Clogging depths range from 10 mm by coarse sand to 60–100 mm by fine sand, necessitating periodic vacuum suction and high-pressure washing for maintenance. PC pavements reduce surface temperatures by 1–3 °C, lowering heat output by 2–5% during rain, promoting environmental sustainability and water conservation.
