Open-Graded Base Courses for Slabs-on-Ground

2016-8-2  Such open-graded (permeable) base courses are intended to serve as subdrainage layers in concrete pavements and as a capillary break that prevents liquid water from rising to the bottom of interior concrete slabs through capillary action in the base course. Open-graded bases are not as stable as densely graded, well-compacted, crushed stone bases.
