THE USE OF ASPHALT PAVEMENT STRUCTURES IN THE AUSTRALIAN ENVIRONMENT

AN ASSESSMENT OF THE USE OF ASPHALT BOUND GRANULAR MATERIALS AS A STRUCTURAL ELEMENT IN AUSTRALIAN ROAD AND AIRFIELD PAVEMENTS IS MADE. AT PRESENT, THESE MATERIALS ARE APPLIED AS SURFACE COURSES TO PAVEMENTS AT AIRPORTS AND IN URBAN AREAS AND THEY ARE RELATIVELY EXPENSIVE. RESEARCH IS IN PROGRESS TO COMPARE THEIR BEHAVIOUR WITH THAT OF UNBONDED GRANULAR MATERIALS NOW GENERALLY USED AS THE STRUCTURAL ELEMENT. RESULTS OF THE CONTINUOUS MEASUREMENT OF TEMPERATURE AT VARIOUS DEPTHS IN A 4 INCH LAYER OF ASPHALTIC CONCRETE AT A SITE NEAR MELBOURNE ARE GIVEN. MODEL EXPERIMENTAL SECTIONS HAVE BEEN LAID AT ONE SITE TO COMPARE THE LOAD SPREADING PROPERTIES OF THE TWO TYPES OF BASE MATERIALS AND, BY SURFACE AND SUBGRADE DEFLECTION COMBINED WITH SUBGRADE STRESS MEASUREMENTS, THEIR RELATIVE BEHAVIOUR IS DEMONSTRATED. /AUTHOR/
