Pervious concrete pavements (PCPs) have been widely accepted as a green infrastructure solution for urban areas. Currently, pervious concrete is commonly used in permeable pavement systems such as roadways, sidewalks, driveways, parking lots, and other light-duty flatwork applications. However, the main disadvantage of this type of pavement is that it loses permeability over time due to clogging and lower compressive strength due to the pore's structures. These critical issues are the topic of this review paper. Laboratory test results relevant to the compressive strength, clogging and maintenance are discussed in detail. This review aims to present a compilation of prominent findings of studies focused on compressive strength, clogging and maintenance of PCPs. Note that PCPs with higher compressive strength must be used on roads with high traffic volumes. Subsequently, periodic maintenance is necessary to prevent sediment clogging and maximise the life of PCPs. Based on this review paper, the area of need for future research are identified.

The development of recycled aggregate concrete (RAC) provides a new approach to limiting the waste of natural resources. In the present study, the mechanical properties and deformability of RACs were improved by adding basalt fibers (BFs) and using external restraints, such as a fiber-reinforced polymer (FRP) jacket or a PVC pipe. Samples were tested under axial compression. The results showed that RAC (50% replacement of aggregate) containing 0.2% BFs had the best mechanical properties. Using either BFs or PVC reinforcement had a slight effect on the loadbearing capacity and mode of failure. With different levels of BFs, the compressive strengths of the specimens reinforced with 1-layer and 3-layer basalt fiber reinforced polymer (BFRP) increased by 6.7%-10.5% and 16.5%-23.7%, respectively, and the ultimate strains increased by 48.5%-80.7% and 97.1%-141.1%, respectively. The peak stress of the 3-layer BFRP-PVC increased by 42.2%, and the ultimate strain improved by 131.3%, relative to the control. This reinforcement combined the high tensile strength of BFRP, which improved the post-peak behavior, and PVC, which enhanced the structural durability. In addition, to investigate the influence of the various constraints on compressive behavior, the stress-strain response was analyzed. Based on the analysis of experimental results, a peak stress-strain model and an amended ultimate stress-strain model were proposed. The models were verified as well; the result showed that the predictions from calculations are generally consistent with the experimental data (error within 10%). The results of this study provide a theoretical basis and reference for future applications of fiber-reinforced recycled concrete.

“…Zhang [27] found that the proportion of fly ash replacing cement in permeable concrete should not exceed 20%. Liu [28] showed that the compressive strength of fly ash permeable concrete developed well after more than 150 d. Admixtures, such as fly ash [29], pumice powder and nano-clay [30], recycled low-quality brick-concrete [31], pulverized biochar [32], coal ash and rice husk ash [33], or a new admixture [34], were added to prepare environmentally friendly permeable concrete materials. Exceeding the best content will have an adverse impact on the strength and permeability of permeable concrete.…”

Urban construction has produced a large amount of construction waste which has caused huge environmental problems. The sponge city is the development direction of urban construction, and permeable pavement concrete is an important material for sponge city construction. To see the law influencing different factors on the performance of recycled aggregate permeable pavement concrete, different water binder ratios, recycled aggregate particle gradations, ordinary aggregate substitution rates, and fly ash and admixture contents are designed to prepare permeable concrete. The compressive strength, permeability coefficient, frost resistance, and pore structure of permeable concrete are tested. The results show that when the replacement rate of recycled aggregate is 50%, the 28-d strength of concrete with a 0.25 water binder ratio can reach 28.9 MPa, and the permeability coefficient is 13.26 mm/s. The addition of fly ash will reduce the compressive strength, and the permeability coefficient increases first and then decreases with the increase of the fly ash content. When the mass fraction of fly ash instead of cement is 12%, the 28-d strength is 94.8% of that of the cement group, and the permeability coefficient can reach 14.03 mm/s. A water-reducing agent can obviously improve the workability of permeable concrete; the best content of the water-reducing agent is 0.2% of the cement mass. A reasonable amount of fly ash and water-reducing agent can optimize the number of harmless holes and less harmful holes in the concrete to improve the frost resistance and strength after the freeze–thaw, and the frost resistance is F150. This study provides a theoretical basis and technical guarantee for the resource utilization of recycled aggregate in permeable pavement concrete.
