Measurement of Permeability and Comparison of Pavements

Abstract

Permeable pavements have the ability to reduce surface runoff by allowing water to infiltrate into the underlying soil. The potential of permeable pavements to assist in managing stormwater and improve water quality has gained attention as an option, other than conventional impermeable concrete for paving purposes. This study examined the permeability of three different pavement systems, including the JW Eco-technology pavement (JW), which has not previously been installed or studied in the U.S., standard impermeable concrete (IC), and pervious concrete (PC). Each pavement type was installed in triplicate. Devices based on the ASTM C1701/C1701M and ASTM C1781/C1781M constant-head methods, the National Center for Asphalt Technology (NCAT) falling-head permeameter, and two new square frames, SF-4 and SF-9, modified to fit the JW pavement, were utilized for permeability measurement on several locations of each pavement system. The results showed that the JW Eco-technology pavement had comparable permeability to the commonly used PC pavement in each method used. In addition, there was a strong correlation between the permeability measurements of NCAT method and SF-4, and between the ASTM standard and SF-9. The square frames used in this study showed their effectiveness and efficiency in performing permeability measurements. It was also found that the permeability obtained had a pronounced difference in values between the falling head and the constant head methods, with an average ratio ranging from 4.08–6.36.

How Can Sustainable Materials in Road Construction Contribute to Vehicles’ Braking?

“…Hence, it may be stated that pavement surfaces with open-graded asphalt mixes exhibited a better frictional performance when contaminated by wet dust or aggregate particles. This issue comes in accordance with the so far knowledge on this subject [43,44].…”

Advancing Pervious Pavements through Nomenclature, Standards, and Holistic Green Design

“…Alternatively, Jayasuriya and Kadurupokune extrapolate pervious pavements as a general category of pavements reducing run-off and filtering sediments, www.videleaf.com under which are porous pavements (a -thick porous layer with strong infiltration capacity‖) and permeable pavements (-normally constructed by impervious paver concrete blocks with infiltration voids between the blocks‖) [31]. In their comparative study, Chen et al [46] acknowledge inconsistencies in pavement nomenclature and testing results, frequently citing Li [47]. Commenting on the -state of the art‖, Pantsi et al [48], citing Alsubih [49], consider -pervious pavement‖ an overarching term containing -porous pavement‖ (continuous surface) and -permeable pavement‖ (discontinuous surface).…”

“…Within the academic literature, studies and reviews of the physical properties of different pervious pavement compositions continue to be published at an extraordinary rate [54,55,18,46]. As researchers explore unique components such as palm kernel shells [56], waste tire rubber [57], recycled aggregate concrete [58], and recycled plastics [54], and special applications like overlays [59] and integrated perforated pipe pathways [60], the high volume of publications will undoubtedly continue.…”

“…www.videleaf.com Almost a decade ago, uses of silica fume, superplasticizer, and polymer modification achieved porous concrete compressive strengths of 32-46 MPa (4640-6670 psi) [55]. For the most common applications of pervious pavements, low traffic roadways, walkways, and parking lots, several examples of decades-long durability have been documented across different types of pervious pavements [17,46]. As an example, a U.S. EPA study found porous asphalts to have lower freeze/thaw stress than conventional pavement, potentially leading to a doubling of service life from 15 to 30 years (in continental or polar climates) [66].…”

Urban stormwater characterization, control, and treatment

“…Infiltration testing of an innovative load‐bearing permeable pavement with a unique structure and design called the JW Eco‐technology pavement was conducted by Chen, Chen, Chen, Chen, Lecher, and Davidson (2019). The pavement reportedly has the load‐bearing capacity of a standard roadway.…”
