THE PERFORMANCE OF SINGLE SEALS LAID ON FIVE MAIN HIGHWAYS IN VICTORIA DURING THE PERIOD 1938-1959

A SURVEY WAS MADE OF THE LIVES OF BITUMEN SEALS /MAINLY RESEALS / LAID ON FIVE MAIN HIGHWAYS IN VICTORIA DURING THE PERIOD 1938-1959. TECHNICAL INFORMATION ON THE CONSTRUCTION OF THE SEALS AND ON THE AMOUNT AND TYPE OF TRAFFIC WHICH THEY CARRIED WAS ALSO OBTAINED. THERE WAS SUFFICIENT INFORMATION ON SINGLE SEALS FOR A LIMITED ANALYSIS OF FACTORS INFLUENCING THEIR LIFE. AVERAGE LIFE INCREASED WITH THE SIZE OF THE AGGREGATE USED RANGING FROM 8 YEARS FOR A SAND RESEAL TO 15 YEARS FOR A RESEAL USING 5/8 IN. SIZE STONE. THE PERFORMANCE OF SEALS LAID IN THE 1948-1954 PERIOD WAS INFERIOR TO THOSE LAID BOTH BEFORE AND AFTER. THIS BEHAVIOUR IS ATTRIBUTED TO THE MAJOR USE OF KLAMONO /NEW GUINEA/ BITUMEN DURING THIS PERIOD. EXTENSION OF THE SURVEY TO OTHER ROUTES SHOULD GIVE MORE INFORMATION ON PERFORMANCE OF LIGHTLY TRAFFICKED ROADS AND PROVIDE MORE EXAMPLES OF INITIAL SEALING. /RRL/A/
