REVIEW, SELECTION AND CALIBRATION OF ACCELERATED WEAR AND SKID RESISTANCE TESTING EQUIPMENT - INTERIM REPORT-PHASE 1

THE PRIMARY OBJECTIVE OF THIS REPORT IS TO CONVEY THE BASIS FOR SELECTION OF TESTING EQUIPMENT BEING UTILIZED DURING THE CONDUCT OF PROJECT IHR-406. VARIOUS TECHNIQUES AND DEVICES WERE REVIEWED AND SELECTIONS WERE MADE PRIOR TO ACQUISITION OF SPECIFIC ITEMS OF EQUIPMENT. A FURTHER OBJECTIVE IS TO RELATE THE PROGRESS THAT HAS BEEN MADE ON THE RESEARCH PROJECT SINCE ITS INCEPTION OF DECEMBER 15, 1970. THE MAJOR EMPHASIS HAS BEEN DIRECTED TOWARDS 1) CALIBRATION OF THE TESTING EQUIPMENT, AND 2) SAMPLE ACQUISITION. SINCE ONLY LIMITED FIELD WORK AND LABORATORY TESTING TO ESTABLISH PHYSICAL PROPERTIES OF SELECT AGGREGATES (LOS ANGELES ABRASION, SOUNDNESS, ACID INSOLUBLES, ETC.) HAS BEEN PERFORMED TO DATE, DISCUSSION OF THIS EFFORT IS MINIMIZED IN THE REPORT. A REPORT FOR PHASE 2 OF THE RESEARCH PROJECT WILL CONTAIN A DETAILED DISCUSSION OF THE LATTER INFORMATION AND FIELD TEST PROCEDURES USED. THE REPORT CONTAINS A SUMMARY OF EXISTING LITERATURE, PROJECT OBJECTIVE AND WORK PLAN, THE ESTABLISHED EQUIPMENT REQUIREMENTS FOR MEASURING SEVERAL PARAMETERS, AND ACCOMPLISHMENTS TO DATE. IN ADDITION, THE PROCEDURES FOR USE OF THE SELECTED TEST EQUIPMENT IS OUTLINED. THE APPENDICES CONTAIN A BRIEF DESCRIPTION OF ALTERNATE TEST EQUIPMENT AND PROCEDURES. SUCCESSFUL CONCLUSION OF PROJECT IHR-406 SHOULD LEAD TO 1) A RECOMMENDED METHOD FOR PREEVALUATING THE WEAR AND POLISHING RESISTANCE OF AGGREGATES, AND 2) RECOMMENDED AGGREGATE ACCEPTANCE LEVELS TO PROVIDE SKID RESISTANT PAVEMENT SURFACES. /FHWA/
