Title: Mixture Proportion Development and Performance Evaluation of Pervious Concrete for Overlay Applications
Author(s): John T. Kevern, Vernon R. Schaefer, and Kejin Wang
Publication: Materials Journal
Appears on pages(s): 439-448
Keywords: concrete overlay; durability; freezing and thawing; pervious concrete; storm-water management; sustainability
Abstract:This paper describes the results of studies to develop pervious concrete for use as an overlay material over traditional concrete to reduce noise, minimize splash and spray, and improve friction as a surface wearing course. Workability and compaction density testing methods were developed to ensure constructibility and placement consistency. The mixture testing matrix consisted of evaluating aggregate type and gradation, cementitious material amounts and composition, and various admixtures. Selected mixtures were tested for permeability, strength, workability, overlay bond strength, and freezing-and-thawing durability. The selected mixture was self-consolidating and slip-formable and was placed at the MnROAD testing facility during late October 2008. The test results indicate that pervious concrete mixtures can be designed to be highly workable, sufficiently strong, permeable, and have excellent freezing-and-thawing durability, thus being suitable for pavement overlays.
