AASHTO has marked a milestone in communicating technical credibility and reliability of properly designed, constructed, and maintained vehicular, service or pedestrian interlocking concrete pavements. Its recently released Guide to Interlocking Concrete Pavements covers materials, design, construction, and maintenance as well as resilient and sustainable aspects of technologies originally transferred from Europe to North America in the 1970s. In addition to conventional paver practice, the publication addresses permeable interlocking concrete pavements—well timed with public or private owners’ needs for solutions to reduce stormwater runoff, pollution and flooding.
Issued by AASHTO Committee on Materials and Pavements and developed under the Subcommittee on Pavement Design and Chair Dr. Dulce Ruffino Feldman, P.E. (Caltrans), the 129-page guide passed through technical review with assistance from consultants to AASHTO and association staff. The content is authored by David R. Smith, a 40-year veteran of interlocking concrete pavement production, standards and practice, and now a consultant to the industry.
