Four years in the making, the standard covers hydrologic sizing and structural design of PICP as well as construction and maintenance guidelines. The intent of the standard is adoption in whole or part by provincial, state, and municipal road agencies as well as by stormwater agencies and green infrastructure managers. ASCE/ANSI 68-18 is a detailed guide for civil and environmental engineers. It provides informative reading for environmental planners, landscape architects, and architects. Chaired by David K. Hein, P. Eng., the standard was written by a committee of PICP experts from across the U.S. and Canada representing industry, consulting civil engineers, stormwater agencies and contractors. Mr. Hein notes that, “PICP is seeing increased used for parking lots, alleys and streets. The ASCE 68-18 standard provides a high level of design confidence in PICP performance drawn from research that determines pavement thicknesses.” “PICP is seeing increased used for parking lots, alleys and streets.

PICP can be reliably designed to accept some bus and truck traffic as shown here at the Chicago Museum of Science & Industry.
