ICP 1: Guide Specifications for Interlocking Concrete Pavements
This course is no longer active. AEC Daily will not report completion information for this course.
Interlocking concrete pavements are appropriate for any application that requires paving, and durable, creative interlock begins with clear and technically accurate specifications. This presentation moves through every section of ICPI Tech Spec 9: Guide Specification for the Construction of Interlocking Concrete Pavement to show how quality assurance is achieved through specifications.
Upon completion of this course, the Learner should be able to:
- Demonstrate why interlocking concrete pavements create strong, stable surfaces for pedestrian and vehicular traffic by examining their components to show how they work together to create interlock.
- Illustrate why interlocking concrete pavements can create smooth surfaces without tripping hazards when recommended tolerances on lippage, joint size tolerances and the correct edge restraints are installed.
- Identify the most effective and appropriate interlocking concrete pavement patterns and joint widths that support pedestrian, vehicular, industrial, port and aircraft uses safely.
- Evaluate a project site and determine the factors that may affect the structural performance, durability and safety of an interlocking pavement installation by assessing the kind of base required and the type, strength and thickness of all available paving materials.
- Specify interlocking concrete pavements and verify critical aspects of their construction from submittals to execution and then to final inspection.

Presenter Information

Name: David R. Smith
Title: Technical Director, Interlocking Concrete Pavement Institute
Background: Since building his first project in 1977, David R. Smith has worked with civil engineers, architects, landscape architects, and contractors on the design, construction, and maintenance of interlocking concrete pavements (ICP). Besides publishing dozens of articles, peer-reviewed technical papers, guide specifications, and Interlocking Concrete Pavement Institute (ICPI) Tech Spec technical bulletins, Mr. Smith has coauthored student and instructor manuals for contractor courses, taught these courses, and created and presented many continuing education programs. In addition, he has authored three design idea books from Schiffer Publishing. He was editor from 1994 to 2018 of the quarterly Interlock Design magazine (circ. 17,000) featuring ICP projects. Since 1988, Mr. Smith has written or revised several product standards and test methods through membership in ASTM. He also serves as chair of the Small Element Pavement Technologists.
