Free cracking is allowed in CRCP but the cracking pattern is controlled by the continuously longitudinal reinforcement. The problem is that in reality the crack pattern is not as desired.
Distances between cracks are sometimes smaller, creating clusters of cracks. They are lccp responsible for the punch-out effect. With active crack control one tries to force the position of these cracks in the young concrete pavement by making some cuts in the road, where the cracks will then originate.
ALIZE-LCPC – LE LOGICIEL POUR LE DIMENSIONNEMENT DES STRUCTURES DE CHAUSSEES
One tries to find optimal dimensions of the saw cuts which result into a uniform crack pattern. To do this, a numerical 2D model of a road segment is made with the finite element program Samcef Field. Deformations and stresses in the concrete and reinforcement are compared.
The cfack between the notches and the width and depth of the saw cut are varied and results are compared. A 3D model is generated based on the 2D model and discussed in detail.
For this model, the length is varied and results are compared. This study helps to develop and improve the active crack control technique. However, in order to understand the actual crack behaviour of CRCP with active crack control at early-age, it is necessary to conduct site tests on actual CRCP, because simulating CRCP with software has some limitations, as shown by this research.
In future research these models should be used in combination with investigations on the field.
