STRESSES ON RIGID PAVEMENTS IN ACCORDANCE WITH SPECIFICATION TV CONCRETE 72

TESTS WERE CARRIED OUT TO DETERMINE THE STRESSES ON RIGID PAVEMENTS CAUSED BY ALTERATIONS IN TEMPERATURE AND BY TRAFFIC LOADING. A DISTINCTION WAS MADE BETWEEN LOADS IN THE CENTER AND AT THE EDGE OF THE SLAB. THE TESTS WERE CARRIED OUT WITH FIVE CLASSES OF TRAFFIC. IT IS SHOWN THAT FOR CONCRETE PAVEMENTS DESIGNED FOR TRAFFIC CLASSES 1 AND 2, WHICH HAVE A DISTANCE OF 5 M BETWEEN CONTRACTION JOINTS, THERE IS NO EXCESSIVE STRESS. IF A STABILIZED ROADBASE IS ALSO PROVIDED, A VERY LONG LIFE MAY BE EXPECTED FROM THESE PAVEMENTS. FOR RIGID PAVEMENTS DESIGNED FOR TRAFFIC CLASS 3 AN 18 CM THICK SURFACING IS SUFFICIENT. HERE A DETERMINING FACTOR IN THE STRESS IS THE LOAD AT THE EDGE OF THE SLAB, AND CONSTRUCTION WITHOUT EXPANSION JOINTS IS RECOMMENDED. IN THE CASE OF THE 15 CM THICK SURFACING FOR THE TRAFFIC CLASS 4 STRESS IS CAUSED AT THE EDGE OF THE SLAB BY THE TRAFFIC LOADING, AND FOR THE 12 CM THICK SURFACING FOR TRAFFIC CLASS 5, CRACKING MUST BE EXPECTED IN THE CENTER OF THE SLAB AFTER A FEW ALTERNATING LOADS. /TRRL/ 5, CRACKING MUST BE EXPECTED IN THE CENTER OF THE SLAB AFTER A FEW ALTERNATING LOADS. /TRRL/
