Abstract

One of the major stresses which develop in CONCRETE PAVEMENTS is the THERMAL STRESSES. Since concrete is less able to deform in response to temperature changes than bituminous materials, THERMAL STRESSES have to be taken into account as well as traffic stresses in analysing the behavior of CONCRETE PAVEMENTS. Temperature stresses in concrete slabs can be divided into three categories namely, end restraint compressive stress, foundation restraint compressive and tensile stress and partially or completely restrained warping stresses. Since the concrete has a high compressive strength, the first category does not take into account, but developing the two other kinds of THERMAL STRESSES in CONCRETE PAVEMENTS are inevitable and when added to traffic stresses here are called COMBINED STRESSES. The combination of these can cause cracking and failure in pavements. The conclusion of this investigation showed that the day time COMBINED STRESSES have an adverse relation to the length of slabs while the night- time COMBINED STRESSES are directly proportional to the slab's length. From comparing the various results it was concluded that the results from Westergaard equations normally overestimate the CURLING STRESSES for both day and night times by 17% and 30% respectively.
