THIS REPORT DEALS EXTENSIVELY WITH THE PROCEDURES ESTABLISHED FOR THE RATING OF SEAL COATS. FIVE MAJOR FACTORS INFLUENCING THE OVERALL PERFORMANCE OF SEAL COATS ARE EVALUATED INDEPENDENTLY AND NUMERICAL VALUES RANGING FROM 0 TO 20 ARE ASSIGNED TO EACH FACTOR. THESE FACTORS ARE CHIP RETENTION, SKID RESISTANCE, UNIFORMITY OF APPLICATION, CRACKING AND BLEEDING. THE SUMMATION OF ALL OF THE NUMBERS ASSIGNED TO EACH FACTOR IS AN INDICATION OF THE OVERALL PERFORMANCE AND CONDITION OF THE RATED SEAL COAT. A SIMILAR METHOD IS REPORTED FOR RATING THE CONDITION OF UNDERLYING SURFACES PRIOR TO THE APPLICATION OF THE SEAL COATS. ALSO INCLUDED ARE TWO TYPICAL FORMS THAT ARE USED TO RECORD THE RESULTS OF THE RATING. /AUTHOR/
