Tech Spec Update

The Interlocking Concrete Pavement Institute (ICPI) announced updates to two of its popular Tech Spec technical bulletin series. “Tech Spec 10 Application Guide for Interlocking Concrete Pavements” and “Tech Spec 15 A Guide for the Specification of Mechanically Installed Interlocking Concrete Pavements” received significant edits.

Tech Spec 10 is completely revised to be the “starter piece” for design professionals and contractors. Organized in a manner similar to the Construction Specifications Institute (CSI) SpecData™ sheets, the revised Tech Spec demonstrates the range of applications suitable for interlocking concrete pavements and provides essential information on each. The reader is directed to specific ICPI design, installation and maintenance resources for these applications. The bulletin treats interlocking concrete pavement as a pavement system and gives direction on how to adapt that system to specific applications. For that reason, Tech Spec 10 should be the first read among the series of 17 ICPI Tech Spec technical bulletins as free downloads on ICPI website.

The title for Tech Spec 15 was modified to more clearly indicate that the bulletin is about considerations when writing specifications for machine-installed concrete pavers. This method of installation accelerates construction time compared to manual methods, while managing costs and maintaining crew energy. It has been used on countless street, industrial, port and airport projects in North America and overseas. Specifications using this installation method are framed around a method statement where the paver manufacturer, paver installation contractor and testing laboratories provide specific information on the paving and bedding materials, test methods and frequencies, installation methods and measures for documenting project quality control/quality assurance.

The original Tech Spec version was framed from lessons learned on large port paving projects, including the Port of Oakland, CA, built in the early 2000s with approximately 4.7 million sf (470,000 m2) of interlocking concrete pavement for container handling facilities. The updated version provides additional information on placing and stitching paver clusters, i.e., the individual paver layers typically cover a square yard (m2) and consis of 35 to 45 concrete pavers manufactured in the final (or near final) laying pattern. The selection of paver layers and the decision to stitch them together primarily affect installation costs and secondarily, pavement performance. Criteria are provided for when and how to stitch together selected paver layers or clusters.
