Development of a Pavement Condition Rating Procedure for Interlocking Concrete Pavements

Most North American cities are using a pavement management system (PMS) for their streets to budget maintenance and future rehabilitation costs. The condition data in a PMS database can also be used as an engineering tool to evaluate the real-life performance of pavement thickness design, mix design, material composition, and construction specifications. Many municipal PMS programs incorporate pavement condition evaluation guidelines that follow the U.S. Army Corps of Engineers MicroPAVER distress guide (published by ASTM) to evaluate flexible and rigid pavements. While there has been some research completed to develop methods of evaluating the condition of interlocking concrete pavements (ICP's), there is no common methodology currently in practice in North America. This paper outlines the procedures used to develop a pavement distress guide for flexible ICP's following the MicroPAVER protocol. The paper provides an overview of the procedures used to develop the distress guidelines for interlocking concrete block pavements, summarizes the results of the analysis and provides an example of the use of the procedures to determine the pavement condition index for a roadway constructed using ICP's as a running surface.
