Revised 2020
Note: This guide specification for U.S. applications describes construction of permeable interlocking concrete pavers on a permeable, open-graded crushed stone bedding layer (typically ASTM No. 8 stone). The pavers and bedding layer are placed over geotextile-covered structural soil. This guide specification does not cover excavation, impermeable liners, perforated underdrain pipes, or structural soils. See CU-Structural Soil® A Comprehensive Guide for design and specification information. The application is for pedestrian use only. This pavement surface allows water to enter the soil thus benefitting trees and other vegetation planted in it while supporting pedestrian traffic. See detail drawing ICPI-83. Vehicular applications should be limited to automobiles and to intermittent, occasional use.
