“…Once clogging occurs at the sites and the infiltration ability decreases, runoff will increase, and retention and groundwater recharge will decrease. The permeable pavement might experience clogging in the first 2-3 years, which leads to a reduction in permeability [30][31][32]. The sediment loads in locations affect the clogging level [33,34]; therefore, regular maintenance, such as sweeping and cleaning, is suggested [34].…”

Low-impact development (LID) structures are widely used to mitigate urbanization impacts on hydrology. The performances of such structures are strongly affected by field conditions, such as the ratio of LID area to drainage area and rainfall properties, such as rainfall intensity. In this study, onsite continuous monitoring was performed at a permeable pavement site and a raingarden site in Taipei, Taiwan, to determine their water retention and groundwater recharge potential under subtropical weather. In addition, the verified Storm Water Management Model (SWMM) was used to illustrate the annual performance on the hydrological cycle. Based on one year of monitoring, data on 41 and 24 rainfall events were obtained at the permeable pavement and raingarden sites, respectively. The ratio of the permeable pavement area to the total drainage area was 36.0%, and this ratio was 15.9% for the raingarden. The results showed that the average runoff reduction rate was 14.7% at the permeable pavement site, and 98.3% of the rainfall was retained in the raingarden and an underground storage tank. The validated model showed that the permeable pavement site experienced 45.3% outflow, 31.6% evaporation, and 23.1% infiltration annually. For the raingarden with an underground storage tank, 91.4% of the annual rainfall infiltrated and was stored, with only 4.1% outflow. According to the observed rainfall event performance and the simulated annual performance, the permeable pavement and raingarden performed well in subtropical regions. Pavement that was approximately 1/3 permeable in a drainage area increased infiltration by approximately 20%, and a raingarden with a sufficient underground storage tank preserved over 90% of the rainfall.

“…Periodic removing of surface sediment particles prevents their deeper penetration inside the concrete matrix and thereby affecting the drain ability of the pavements. The FRNFC specimens subjected to clogging test are then rehabilitated to restore the infiltration rate by standard cleaning methods such as pressure wash (wet cleaning), vacuum sweep (dry cleaning), and combined method [24].…”

The massive development of the construction industry demands sustainability, and the studies on No Fines Concrete (NFC) will support sustainable development in the field of transportation and highway industry. It is the key requirement of all developing countries like India in order to satisfy three main criteria namely sustainability, serviceability and feasibility in addition to its performance. Application of NFC pavement is itself a sustainable method to manage and discharge the retaining stormwater during heavy floods. Fibre Reinforced No Fine Concrete (FRNFC) was considered, with findings suggesting that the inclusion of fibres has minimal impact on strength characteristics and only marginally reduces the permeability of NFC. However, NFC pavements require regular maintenance to prevent clogging of pores with dust, sediments, and debris, which impairs water flow. A 2 m x 2 m span real-time FRNFC pavement was cast and subsequently subjected to assessment of its serviceability performance. The study examines the performance of FRNFC under clogging and suggests rehabilitation methods to reinstate infiltration capacity. Pressure wash combined with vacuum sweep shows the highest Drainage Efficiency Restoration (DER), maintaining drain ability from 99% to 90% after 12 cycles. Routine pressure wash monthly and vacuum sweep yearly are recommended for proper pavement serviceability and effective stormwater runoff mitigation.

Permeable asphalt pavement refers to an asphalt mixture layer with an air void content of more than 18% and internal water permeability and drainage capabilities that can quickly drain away water on the road surface, improve rainy day travel safety, and improve ride comfort. This paper aims to explore the optimal asphalt mixture design for long longitudinal slope pavement (referred to as the FAM mixture). By using CT scanning technology to analyze the air void content of different rotated and compacted asphalt mixture specimens and extensively testing and evaluating the performance of permeable pavement mixtures, the following conclusions are drawn: Based on the research philosophy of functional integration, a new asphalt mixture gradation suitable for long longitudinal slope roads is proposed, with the optimal key factor composition being: 0.075 mm passing rate of 7%, 2.36 mm passing rate of 20%, 9.5 mm passing rate of 55%, and an oil-stone ratio of 4.8%. The FAM mixture was divided into three parts for air void analysis, with the upper part having a slightly higher air void content than the lower part. The air void distribution diagram of the FAM mixture is concave, with higher air void rate curves on both sides and a lower middle curve. Through dynamic modulus testing, the strength requirement for the road asphalt mixture in the pavement structure design was evaluated. It was found that at high temperature conditions (50 °C), the minimum dynamic modulus value of the FAM mixture was 323 MPa, with a peak value of 22,746 MPa at a temperature of −10 °C and a frequency of 25 HZ. The dynamic modulus value at high temperature conditions is lower than at low temperature conditions, while the dynamic modulus value at high frequency conditions is higher than at low frequency conditions. This study provides useful information and experimental data for the design of new asphalt mixtures for long longitudinal slope roads and has conducted in-depth research on the air void distribution and performance of the mixture, providing strong support for related research fields and practical applications.
