Book excerpt: The ends of continuously reinforced and jointed rigid pavements will experience considerable movement; if they are restrained, they will exert considerable force on the restraining mechanism. Structures or pavements that abut these pavements may be damaged unless provisions are made for their protection. There are two approaches to solving the problem. One is to accommodate the movement by providing sufficient space (joints) in which the end of the pavement may move. The other is to partially restrain the ends with some form of anchor system and to provide space to accommodate the reduced movement. Questionnaires revealed that, for CRCP, both procedures are used; anchor lugs may be used and preferred slightly over wide-flange beam joints. For jointed pavement, the predominant procedure used was to accommodate the movement by providing space for the end movement to occur.
