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

ICPI Tech Spec 18: Construction of Permeable Interlocking Concrete Pavement Systems

The new bulletin summarizes permeable interlocking concrete pavement (PICP) and provides guidance on best construction practices. The publication is for contractors and project inspectors, and assists design professionals in understanding construction requirements for project specifications. Tech Spec 18 covers PICP 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.

Tech Spec 18: Construction of Permeable Interlocking Concrete Pavement Systems can be accessed at http://www.icpi.org/techspec18. ICPI members may purchase printed copies in packs of 10 through its online store at https://www.icpi.org/online-store.

A more detailed treatment of design, construction and maintenance is found in ICPI’s comprehensive, 92-page manual entitled Permeable Interlocking Concrete Pavements, available on http://www.icpi.org with extensive information from research and practical field experience.

For contractor training on permeable interlocking concrete pavement systems, ICPI offers a one day PICP Specialist Course on PICP best construction practices. Installers completing the course, passing the exam and meeting the minimum experience requirements earn the PICP Specialist designation. The course covers PICP systems, job planning and documentation, job layout, flow and estimating quantities, soil and site characteristics, subbase and base materials, edge restraints, bedding and jointing materials, paver selection and installation, and maintenance. Visit http://www.icpi.org/picpcourse for more information on dates and locations.
