Comparative analysis of load transfer efficiency in plain and continuously reinforced concrete pavements

In this article, the continuously reinforced concrete pavement (CRCP) was presented, highlighting the recognized international success of the structure due to its high durability and low need for maintenance. The constructive details of four experimental sections of short extension show that the absence of shrinkage joints facilitates the execution process of this pavement and makes it less susceptible to errors typical of simple concrete pavement (SCP) designs. Tests with Falling Weight Deflectometer in the cracks allowed the calculation of load transfer between cracks (LTE). The results indicate a very high LTE for all cracks. Comparatively, LTE data from an experimental SCP located near the CRCP were analyzed. It was found that even without transfer bars and in winter, when the cracks are more open, the CRCP presents LTE values greater than 90%.
