A New Design Method For Control of Cracking in Continuously Reinforced Concrete Pavement

Paper by ABE KAMETA SATO HACBIYA from ISCR 6th 1990

Reinforcement stress and crack width has been in-vestigated in full scale experimental pavement ofContinuously Reinforced Concrete Pavement forthree years. The validity of designequation for pre-dicting crack width distributed through the thick-ness of the slab and reinforcement stress etc.,which is based on bond stress -slip relationshipconsidering the effect of both concrete creep andeccentric arrangement of reinforcing bar from cen-troid of the section, is verified. As a result, theproposed design equation iscapable of estimatingtime- dependent variation of crack width andreinforcement stress with satisfactory accuracy.
