ASPHALT PAVING MIXTURES AND THEIR LAYER EQUIVALENCIES, WITH DISCUSSIONS AND CLOSURE
THREE ASPHALT PAVEMENT STRUCTURES ARE CURRENTLY AVAILABLE TO HIGHWAY ENGINEERS: CONVENTIONAL, DEEP STRENGTH, AND FULL DEPTH. SINCE THE COST PER TON OF ASPHALT CONCRETE IS SUBSTANTIALLY HIGHER THAN THAT OF AGGREGATE, A NUMBER OF FACTORS ARE LISTED TO INDICATE POSSIBLE SOURCES OF ECONOMY IN THE USE OF FULL DEPTH OR DEEP STRENGTH ASPHALT PAVEMENTS. IT IS SHOWN THAT THE USE OF DENSE GRADED PAVING MIXTURES, MADE WITH AGGREGATES OF LARGER NOMINAL MAXIMUM PAVING MIXTURES, MADE WITH AGGREGATES OF LARGER NOMINAL MAXIMUM PARTICLE SIZE, COMPACTION DURING CONSTRUCTION TO 100 PER CENT OF LABORATORY COMPACTED DENSITY, AND THE USE OF THICK LAYERS DURING CONSRUCTION, WOULD MAKE DEEP STRENGTH AND FULL DEPTH PAVEMENTS LESS EXPENSIVE AND MORE COMPETITIVE. THE LAYER EQUIVALENCY VALUES PROVIDED BY A NUMBER OF TEST ROADS ARE EXAMINED. PROGRESS TOWARD THE DEVELOPMENT OF A RATIONAL METHOD OF ASPHALT PAVEMENT STRUCTURAL DESIGN IS REVIEWED. THE LOSS OF SMOOTHNESS OF RIDING QUALITY BECAUSE OF ENVIRONMENTAL FACTORS IS LITTLE UNDERSTOOD, POSING A PROBLEM EVEN AFTER A RATIONAL DESIGN METHOD FOR ASPHALT PAVEMENT DESIGN COMES INTO GENERAL USE. /AUTHOR/
