Permeable pavement is a technology that allows rainwater to infiltrate into the pavement. Permeable pavements not only help reduce surface runoff by allowing rainwater to infiltrate into the pavement, but also improve water quality with the filter layer that removes particulate matter pollutants. This study evaluated the particulate matter removal efficiency of bottom ash–sand mixtures as filter layers for removing fine (≤10 μm) or ultrafine (≤2.5 μm) particulate matter in the laboratory. Five filter media were tested: silica sand, bottom ash, and bottom ash–sand mixtures with 30:70, 50:50, and 70:30 ratios. The mixed filters exhibited more consistent and stable particulate matter removal efficiency over time than either the uniform sand or bottom ash filter. The 50:50 bottom ash–sand mixture demonstrated removal rates of 58.05% for 1.8 μm particles, 93.92% for 10 μm particles, and 92.45% for 60 μm particles. These findings highlight the potential of bottom ash–sand mixtures as effective filter media for removing PM10 road dust, although field validation with actual pavement systems is necessary.

“…The studies reviewed above demonstrate the wide variety of findings that are possible from different investigations related to the hydraulic properties of permeable pavements. While studies have shown that the pavement performance-in terms of clogging-is dependent on a number of parameters [9,13,[15][16][17]20,21], there are no established test procedures or standardized methods for evaluating the hydraulic capacity of a permeable pavement, especially in laboratory models [5,9]. This is particularly evident from the three pieces of literature widely reviewed here.…”

“…As these pollutants are being trapped within the joints and layers of the permeable pavement, the drainage performance of the pavement is at risk of failure, until it finally reaches an unacceptable level [6,9,12]. To better understand the clogging and filtration processes within permeable pavements, many studies have been conducted to assess the long-term hydraulic capacity through field and laboratory experiments [6,[13][14][15][16][17][18][19].…”

“…In 2017, Ahn et al [15] developed a lab-scale apparatus for measuring the permeability of various pervious materials, which were not limited to pavement materials, but also to soils. Their apparatus ( Figure 4) had more flexibility in terms of test methods, as it could perform both constant head and falling head permeability tests.…”

“…The bedding sand was tested first to verify the laminar condition of flow through the porous material using a smaller version of the equipment. The details of the small permeability equipment are discussed in the paper by Ahn et al [15]. A total of eight constant head permeability tests were conducted at approximate hydraulic gradients of 0.5, 1.0, 1.5, and 2.0.…”

Abstract:The use of permeable block pavement has been acknowledged as one of the promising Low Impact Development (LID) strategies to mitigate the harmful effects of depletion of natural surfaces, due to the uncontrollable development of infrastructure and buildings. Numerous studies, associated with drainage properties and long-term performance of this traditional pavement alternative, have been conducted in the past 30 years. Nevertheless, standardized equipment and methodologies are still limited, specifically for small-scale laboratory models. This paper suggests equipment that is capable of evaluating the hydraulic performance of permeable pavement materials in a laboratory set-up, by monitoring permeability and simulating the physical clogging process. Constant head permeability tests with systematic application of fine clogging particles were conducted on three identical permeable block systems (PBS), composed of four stone pavers. Each test system received an equivalent amount of eight years' particle loading of silica sand, with different size distributions. The experimental results revealed that all the models showed permeability degradation trends similar to those presented in other literature.
