PERFORMANCE OF ASBESTOS-ASPHALT PAVEMENT SURFACE COURSES WITH HIGH ASPHALT CONTENTS

THE PERFORMANCE OF EIGHT ASBESTOS-ASPHALT PAVEMENTS AND ADJACENT STANDARD PAVEMENTS PLACED IN 1959 AND 1960 IN FOUR CITIES IS EVALUATED THROUGH CORE ANALYSES, SURFACE TEXTURE PHOTOGRAPHS, WATER PERMEABILITY, AND SKID RESISTANCE TESTS. EVEN WITH ASPHALT CONTENT INCREASED 50 PERCENT OR MORE ABOVE STANDARD OPTIMUM, THE PAVEMENT CONTAINING ASBESTOS FIBERS HAVE REMAINED STABLE UNDER HEAVY TRAFFIC. ASPHALT HARDENING HAS BEEN GREATLY REDUCED, WITH PENETRATION OF RECOVERED ASPHALT AT TWO LOCATIONS REMAINING WITHIN THE RANGE OF ORIGINAL PENETRATION GRADE. ALL THESE TEST PAVEMENTS WITH HIGH ASPHALT CONTENTS SHOW SUPERIOR RESISTANCE TO INCIPIENT RAVELING COMPARED WITH ADJACENT STANDARD PAVEMENTS. SIMPLE MIX DESIGN CRITERIA HAVE BEEN ESTABLISHED FOR ASBESTOS- ASPHALT SURFACE PAVEMENTS BASED ON SUPERIOR PERFORMANCE OF THESE TEST SECTIONS TO DATE /AUTHOR/
