FIRST ROAD BASE EXPERIMENT WITH A LABORATORY TEST TRACK, WITH DISCUSSIONS AND CLOSURE

THE TEST TRACK IS A LINEAR APPARATUS CAPABLE OF TESTING PAVEMENT MATERIAL SECTIONS 3 FT. X 4 FT. AND UP TO 13 IN. THICK. THE TROLLEY-MOUNTED TIRE IS CAPABLE OF SPEEDS OF 8 FT/SEC AND LOADS OF 500 POUNDS. MEASUREMENTS OF VERTICAL DEFORMATION WERE TAKEN AFTER A LOAD PATTERN, EACH PATTERN REPRESENTING 100 LOADINGS DISTRIBUTED LATERALLY ACROSS THE PAVEMENT SECTION ACCORDING TO A PROGRAMMED NORMAL DISTRIBUTION. PRELIMINARY RESULTS INDICATE SIGNIFICANT HORIZONTAL MOVEMENTS EVEN FOR A WHEEL THAT APPLIED NO HORIZONTAL FORCE.
