The use of concrete block pavement (CBP) is limited in the U.S. The report examines CBPs from several perspectives to provide an overview of this alternative pavement type. First, the CBP system is described. The importance of using the proper bedding sand gradations is stressed, and the phenomenon of lock-up, or interlock, is explained. The various design methods for CBPs are also presented, and the concept of equivalency factors is discussed. Next, the structural performance of several CBP projects varying from 1 to 10 years is reviewed. Finally, the range of CBP costs in the Puget Sound area are provided and compared to recent WSDOT costs for flexible and rigid pavement.
