ICPI Releases Tech Spec 18

The Interlocking Concrete Pavement Institute (ICPI) has published the newest addition to its popular Tech Spec technical bulletins, Tech Spec 18: Construction of Permeable Interlocking Concrete Pavement Systems.

This bulletin is for contractors and project inspectors, and assists design professionals in understanding construction requirements for project specifications. Tech Spec 18 covers permeable paver components, benefits, recommended sites and important characteristics, sites to avoid, functional descriptions for full, partial and no exfiltration systems, design considerations and a step-by-step description of the construction process, which is also summarized in a convenient check list.

Permeable interlocking concrete pavement (PICP) is recognized by federal, provincial, state and municipal stormwater and transportation agencies as a best management practice (BMP) and low impact development (LID) tool to reduce runoff and water pollution. In addition, PICP offers unique design opportunities for reducing combined sewer overflows with green alleys and streets, as well as with parking lots and pedestrian surfaces. Tech Spec 18 addresses a growing need to educate contractors on installation best practices for this sustainable pavement system.
