Study on Temperature Shrinkage Problem of Oblique-Reinforced Transverse Prestressed Continuous Concrete Pavement

Abstract:

Aiming at different kinds of transverse joints of common concrete pavements, this paper puts forward oblique-reinforced transverse prestressed continuous concrete pavement, and compares it with other reinforcement types of continuous pavements in their mechanical and deformation behaviors under the influence of temperature drop. Analysis results show that oblique-reinforced transverse prestressed concrete pavement could take advantage of deformation transfer competence of oblique steels, and while applying prestressing force on slab along transverse direction, longitudinal prestressing force appears which would effectively counteract temperature shrinkage stress along driving direction. Thus this paper provides corresponding theoretical support for the feasibility study on jointless concrete pavement.
