ANALYTICAL MODELING AND FIELD VERIFICATION OF THERMAL STRESSES IN OVERLAY

This paper describes analytical and graphical procedures for computing thermal stresses at joint locations in pavement overlays. Equations and nomographs are used to calculate stresses caused by horizontal and vertical movements of slabs. Both average temperature drop and maximum temperature differential expected in pavement slabs are determined from temperature distribution noted at time of overlay construction. Stresses caused by slab movement are calculated for different overlays. The results confirm that these often exceed the maximum stresses in asphalt-concrete overlays; therefore, reflective cracking occurs when asphalt concrete is laid over jointed pavements. /Author/
