Interlocking Concrete Block Pavements for Municipal Roadway Applications


Until 2010, there was no recognized national standard for the structural design of interlocking concrete block pavements in North America. It wasn’t until 2006 that the development of a design standard began under a joint project by the Transportation and Development Institute of the American Society of Civil Engineers (ASCE T&DI) and the Interlocking Concrete Pavement Institute (ICPI). So what’s the current design standard? And how can you use it effectively to ensure long-lasting pavements?

Join David Hein, P. Eng., for our webinar exploring the practical aspects of interlocking concrete pavements for municipal road design, and outlining in-depth the procedures and input requirements to optimize the structural design and life expectancy of interlocking concrete block pavements with granular, cement, and asphalt-treated bases.

We’ll kick off this online training webinar by overviewing the standard for interlocking concrete pavement design that was developed by a joint ASCE T&DI and the ICPI committee consisting of representatives of municipal agencies, contractors, manufacturers, and engineering professionals. We’ll learn how the standard established guidelines for the structural design of interlocking concrete pavements with a design speed of up to 70 kilometers per hour in paved areas subject to axle loads up to 10 million 80 kN (18,000 lbs) equivalent single axle loads (ESALs). We’ll then walk through a series of design tables to understand how the interlocking concrete pavement design standard—which was originally based on the flexible pavement design procedure described in the 1993 AASHTO Guide for Design of Pavement Structure—has been condensed to provide minimum thickness for bases and subbases given the design traffic and characterization of the subgrade soil strength and drainage. Throughout the presentation, we’ll study real-life photos and case studies of the best (and the worst) interlocking concrete block pavements to better understand the key components of the structural design standard, how to use it effectively, and the key features of long-lasting, low-maintenance pavement.

Topics we’re covering include:

  • Design principles, design life, and traffic analysis
  • Subgrade soils assessment for strength and drainage characteristics
  • Pavement base and subbase materials selection and thickness design
  • Drainage details
  • Construction details and specifications
  • Quality control and assurance for maximum performance

Who should attend?

  • Architects, engineers and technicians involved in roadway design, construction and maintenance
  • Municipal staff involved in the maintenance and rehabilitation of pavements
  • Specifiers and other technical staff involved in the development of roadway specifications

Learning Objectives 
Attendees can expect the discussion and education of the following learning objectives:

  • Understand the structural design of interlocking concrete pavement for municipal roadway applications.
  • Learn how to develop and evaluate structural designs for interlocking concrete pavement.
  • Understand the key aspects of interlocking concrete pavement design to increase pavement lifespan.
