Background and Need
Prior to this research, PICP structural design relied on the flexible pavement design method in the 1993 AASHTO Guide for Design of Pavement Structures. While this design method was developed and validated with full-scale testing for impermeable road pavements, it was adapted by ICPI to use for PICP for subbase thickness design tables up to one million 18,000 lb equivalent single axle loads or ESALs. Coincidentally, Caltrans was writing a guide on permeable pavements and this presented an opportunity to include information on PICP structural design.
