TESTS AND THEORIES ON PENETRATION SURFACES
A PRACTICE IS RECOMMENDED FOR DETERMINING THE AMOUNTS AND TYPES OF ASPHALT AND AGGREGATE FOR A SINGLE SURFACE TREATMENT. THE SQUARE-YARD-TEST-BOARD METHOD WAS USED TO DETERMINE THE EFFECTIVE MAT THICKNESS AND THE SPREAD RATIO OF THE AGGREGATE. AN ASPHALT-QUANTITY CHART IS PRESENTED THAT RELATES THE AMOUNT OF ASPHALT NEEDED TO THE DEPTH THAT THE AGGREGATE IS TO BE EMBEDDED IN THE ASPHALT, THE PERCENTAGE OF VOIDS IN THE AGGREGATE AND THE THICKNESS OF THE AGGREGATE. THE INFLUENCE OF GAP-GRADED AGGREGATES AND FLAT AND ELONGATED PARTICLES ON THE PERFORMANCE OF SURFACE TREATMENTS IS ALSO DISCUSSED. /AUTHOR/
