RATES OF SPREAD AND SPRAY IN BITUMINOUS SURFACE DRESSING OF ROADS

THIS ARTICLE CONTAINS A DESIGN METHOD FOR SURFACE TREATMENTS DEVELOPED FOR USE IN SOUTH AFRICA. IT IS REPORTED TO BE A FAST, EASY, AND ECONOMICAL METHOD OF DESIGN. BASICALLY, A PAN, SIMILAR TO A TEST BOARD, IS USED TO OBTAIN THE QUANTITY OF AGGREGATE. THE AGGREGATE, INSTEAD OF BEING WEIGHED, IS PASSED INTO A CYLINDER AND THE AGGREGATE SPREAD RATIO IS DETERMINED DIRECTLY BY READING A GRADUATED DIPSTICK. THUS, THE AGGREGATE SHAPE IS TAKEN INTO ACCOUNT AUTOMATICALLY. A NOMOGRAPH IS ALSO GIVEN FOR USE IN DETERMINING THE BINDER REQUIREMENT. /AUTHOR/
