The State of Temperature and Shrinkage Stress in CRCP in Curve Areas

Paper by BOTA PANTEL ILIESCU HODA from ISCR 8th 1998 Lisbon Portugal

In the literature of speciality there are studies about the calculus and behavior of continuously reinforced concrete pavements for alignment areas. In our paper we present some aspects of temperature variation and shrinkage stress in curve areas, taking also into account friction, which is determined experimentally in the laboratory. The initial stresses, which are calculated in the hypothesis of uncracked plates, are used for calculating the opening of the cracks. The calculus is made on the basis of the finite element method. The rigidity of the finite elements is determined by taking into account the cracks, and the stress and crack calculus is repeated in one or more iterations.
