Instructor:  David K. Hein, P.Eng

Course Length: 1.5 Hours

Purpose and Background

The design of permeable pavements differs from other traditional pavement systems in that both structural and hydrologic considerations impact the system depth, one of three different infiltration approaches can be used based on site and subgrade conditions, and unique elements are included over sloped subgrades.

New to the ASCE standard is structural design for supporting traffic by using a mechanistic-empirical model that was developed through full-scale accelerated testing research completed at the University of California Davis Pavement Research Center. The impact of pavement loading is modelled using the pavement layer and subgrade stiffness under dry and wet conditions to determine when a user specified rut depth results from traffic loading.

This webinar outlines technical advances in permeable interlocking concrete pavement (PICP) design introduced in the newly created American Society of Civil Engineers (ASCE) standard. This webinar discusses the dichotomy between not compacting the soil subgrade for infiltration, and compacting for enhanced structural support in saturated conditions. Guide construction specifications, construction and maintenance guidelines are provided via checklists.
