LOAD TRANSMISSION TEST FOR FLEXIBLE PAVING AND BASE COURSES

THIS PROGRESS REPORT TO THE COMMITTEE ON FLEXIBLE PAVEMENT DESIGN DESCRIBES TESTS DESIGNED BY THE CIVIL AERONAUTICS ADMINISTRATION TO DETERMINE LOAD TRANSMISSION THROUGH FLEXIBLE PAVEMENT SLABS OR BASE COURSES ON AIRPORT RUNWAYS. A TEST INSTALLATION WAS DEVISED THAT COMPRISES 2-INCH-SQUARE PLATES PLACED SIDE BY SIDE IN 60 ROWS OF 60 PLATES. EACH PLATE IS SUPPORTED BY A STEEL PLUNGER THAT OPERATES AGAINST A COIL SPRING. THE SPRING--PLUNGER ASSEMBLY OPERATES WITHIN A VERTICAL GUIDE CYLINDER WHOSE BOTTOM IS SET INTO BASE PLATES. OTHER DESIGN AND OPERATING CHARACTERISTICS ARE DESCRIBED IN DETAIL. IT IS HOPED THAT PRELIMINARY RESULTS WILL BE READY DURING 1950. IT IS NOT EXPECTED THAT TEST RESULTS WILL BE DIRECTLY APPLICABLE TO DESIGN PROBLEMS, BUT THEY SHOULD GIVE A QUALITATIVE INDICATION OF THE COMPARATIVE EFFECTIVENESS OF VARIOUS MATERIALS AND MIXTURES IN DISTRIBUTING CONCENTRATED LOADS, IN ADDITION TO SHOWING THE EFFECTS OF VARIATIONS IN UNIT LOAD, LOADED AREA, PAVING THICKNESS, AND OTHER FACTORS.
