CONCRETE RESISTANCE TESTS HAVE BEEN MADE WITH THE TALBOT-JONES RATTLER. RESULTS ARE DISCUSSED OF SEVERAL INVESTIGATION INVOLVING THE USE OF THIS APPARATUS. SEVERAL STUDIES HAVE CONCLUDED USING THIS IMPACT APPARATUS THAT THE RESISTANCE DEPENDS UPON THE QUALITY OF THE MORTAR AND THE COARSE AGGREGATE, AND ALTHOUGH A GOOD MATRIX HAS A TENDENCY TO SUPPORT A WEAK COARSE AGGREGATE, THE USE OF A GOOD QUALITY OF THE LATTER WILL MAKE A MORE DURABLE PAVEMENT. HOWEVER, OTHERS REPORT THAT HIGHER COMPRESSIVE STRENGTHS DO NOT IN ALL CASES GIVE GREATER RESISTANCE TO WEAR. IT IS FELT THAT THE JONES-TALBOT RATTLER TEST IS NOT RELIABLE FROM VARIOUS RESULTS REPORTED. IT IS RECOMMENDED THAT AN APPARATUS BE DEVELOPED FOR MEASURING ACTUAL WEAR ON ROADS.
