MATERIAL QUANTITIES FOR SEAL COATS AND SURFACE TREATMENTS
THE PRINCIPLE OBJECTIVE OF THE INVESTIGATION WAS TO OBTAIN BASIC INFORMATION THAT WOULD PERMIT EVALUATION OF THE THICKNESS OF THE BITUMINOUS FILM AND PROPER GRADE AND TYPE OF BITUMINOUS MATERIAL AS RELATED TO THE SIZE AND TYPE OF AGGREGATE FOR SEAL COAT AND SURFACE TREATMENT CONSTRUCTION. PART A OF THE REPORT RELATES INFORMATION CONCERNING THE VOID CONTENTS OF SINGLE AND MULTIPLE SURFACE TREATMENT AGGREGATE LAYERS FOR THE FLAT BOTTOM (NO EMBEDMENT) SITUATIONS. THE INFLUENCE OF SUCH FACTORS AS AGGREGATE SIZE, AGGREGATE SHAPE, AGGREGATE SOURCE, AGGREGATE GRADATION, FINES CONTENT, AGGREGATE TYPE, AND PARTICLE ORIENTATION ON THE VOIDS CONTENT IS REPORTED. PART B OF THE REPORT INCLUDES INFORMATION CONCERNING THE INFLUENCE OF AGGREGATE EMBEDMENT INTO THE UNDERLYING SURFACE ON THE VOIDS CONTENT OF THE SURFACE TREATMENT AGGREGATE LAYER. A PERCENT REDUCTION IS ALSO ESTABLISHED FOR APPLICATION TO THE DATA COLLECTED AND REPORTED IN PART A TO ACCOUNT FOR AGGREGATE EMBEDMENT. IN PART C, A SURFACE TREATMENT DESIGN PROCEDURE DEVELOPED WITH BASIS ON THE DATA COLLECTED IN THIS RESEARCH EFFORT IS PRESENTED. AN EXAMPLE IS INCLUDED TO ILLUSTRATE THE PROCEDURE. PART D OF THE REPORT CONTAINS TABULATIONS OF THE RAW DATA OBTAINED FOR THE SITUATIONS INVESTIGATED. /AUTHOR/
