In recent years, pervious concrete (PC) has gained much attention as one of the strategies for low-impact development (LID) in pavements due to its structural, economic, and road-user benefits. This study sought review evaluate changes mechanical, hydraulic, durability performance PC produced with cement aggregate replacements. A meta-analysis was conducted elucidate feasible range replacement ...

The purpose of this study is to identify the differences in porosity and permeability coefficients when mixing ratio aggregates different present satisfying strength requirement compressive specified a specification Korea. Three mix ratios were suggested by considering various aggregate sizes three cylinders made for each ratio. porosities those evaluated through compression water test, measuri...

This paper investigates the Acid Mine Drainage (AMD) remediation capabilities of pozzolanic pervious concrete Permeable Reactive Barriers (PRBs) with a specific focus on effects flow configuration and contact time efficiency. Raw AMD was collected from an abandoned coal mine. Two configurations, gravity column flow, were tested at laboratory scale gradually increasing times. The two orders magn...

This paper reports the results of a two year field monitoring exercise intended to investigate the pollution abatement capabilities of a novel system which offers an alternative to the, now well established, pervious pavement system as a source control device for stormwater management. The aim of this study was to determine the effectiveness of a live installation of a macro-pervious pavement s...

Conventional visual evaluation techniques (i.e., microscopy) of geomaterials are limited to the inspection of two dimensional surfaces, leaving internal three-dimensional characteristics ambiguous or resulting in costly slice-by-slice assembly to generate three-dimensional representations. Improved X-ray–computed tomography (X-ray CT) technology now allows a sample to be analyzed nondestructive...
