THE RELATION BETWEEN LOS ANGELES ABRASION TEST RESULTS AND THE SERVICE RECORDS OF COARSE AGGREGATES

IN GENERAL, IT APPEARS THAT THERE IS A DEFINITE RELATION BETWEEN THE LOSS IN THE LOS ANGELES ABRASION TEST AND THE SERVICE RECORD OF MATERIALS USED IN CONCRETE, BITUMINOUS CONSTRUCTION, AND SURFACE TREATMENT. ON THE BASIS OF THE DATA AVAILABLE, THE FOLLOWING PERCENTAGES OF WEAR APPEAR TO BE SUITABLE FOR USE IN SPECIFICATIONS TO CONTROL THE QUALITY OF COARSE AGGREGATES: CONCRETE 50%, BITUMINOUS SURFACING 40%, SURFACE TREATMENT 40%. DEFINITE CORRELATIONS BETWEEN THE LOSS IN THE LOS ANGELES TEST AND THE STRENGTH OF CONCRETE ARE FOUND, NAMELY, THE LOWER THE PERCENTAGE OF WEAR, THE HIGHER THE CONCRETE STRENGTH. DEFINITE CORRELATIONS ARE ALSO FOUND WITH THE RESULTS OF A CIRCULAR TRACK ROLLER TEST AND A TEST FOR SOFT OR FRIABLE PIECES. IT APPEARS THAT THE LOS ANGELES TEST GIVES ACCURATE INDICATION OF THE QUALITY OF THE MATERIAL UNDER TEST, AND THAT ITS USE IN SPECIFICATIONS CONTROLLING THE ACCEPTANCE OF COARSE AGGREGATE IS WARRANTED. /AUTHOR/
