COMMENTS ON ASPHALT TREATED BASE COURSES - SYMPOSIUM - ASPHALT BOUND BASES

MATERIALS, ENVIRONMENTAL EFFECTS AND STRESS DISTRIBUTING CHARACTERISTICS ARE DISCUSSED OF ASPHALT TREATED BASE COURSES. INFLUENCE OF THE FOLLOWING FACTORS ARE DISCUSSED: ASPHALT CONTENT, COMPACTION AND RIDING QUALITY. IT IS CONCLUDED THAT BLACK BASES OFFER AN OPORTUNITY FOR A SIGNIFICANTLY IMPROVED FLEXIBLE PAVEMENT IF PROPER ATTENTION IS GIVEN TO THE FOLLOWING DESIGN AND CONSTRUCTION FACTORS: (1) ALL BLACK BASES BE TESTED TO ESTABLISH OPTIMUM ASPHALT CONTENT AND CONSTRUCTION CONTROL PROCEDURES MAINTAINED TO INSURE THAT THE MIX GOES DOWN AT OPTIMUM OR SLIGHTLY BELOW, (2) THE COMPACTION REQUIREMENTS SPECIFIED FOR BINDER COURSES BE SPECIFIED FOR BLACK BASES AND TESTS BE MADE TO INSURE THE REQUIRED COMPACTION IS OBTAINED, AND (3) OTHER FEATURES SUCH AS GRADATION AND LAYER THICKNESS BE CONSIDERED IN THE LIGHT OF THEIR EFFECT ON THE FINISHED RIDING QUALITY AND RIDING QUALITY MUST NOT BE SACRIFICED FOR APPARENT ECONOMIES.
