REPORT ON EXPERIMENTAL PROJECT IN MISSOURI

THE MISSOURI INVESTIGATION PROJECT WAS CONSTRUCTED IN THE SUMMER OF 1941 ON U.S. HWY 169 IN THE NORTHWESTERN PART OF THE STATE. IT SERVED AS A TEST SECTION FOR A 10-YEAR STUDY ON THE EFFECTS OF SPACINGS OF EXPANSION JOINTS IN CONCRETE PAVEMENTS. CLIMATOLOGICAL AND TRAFFIC DATA AS WELL AS DAILY, SEASONAL, AND PERMANENT CHANGES IN JOINT WIDTH AND ELEVATION WERE RECORDED AND CONDITION SURVEYS MADE FOR FAULTING, CRACKING, AND PUMPING. AVERAGE DAILY MOVEMENT IN SHORT SLABS WAS FOUND TO BE INDEPENDENT OF EXPANSION JOINT SPACING, BUT THE USE OF DOWELS REDUCED THE MOVEMENT BY 40%. THE AVERAGE DAILY MOVEMENTS AT EXPANSION JOINTS VARIED WITH LENGTH OF THE SLABS, THE SPACING OF THE EXPANSION JOINTS, AND WHETHER OR NOT DOWELS WERE USED IN THE INTERMEDIATE CONTRACTION JOINTS. DATA ON THE CONDITION SURVEYS, FAULTING, AND MEASUREMENTS OF SEASONAL AND RESIDUAL CHANGES IN JOINT OPENINGS ARE GIVEN.
