MADAWASKA ASBESTOS ASPHALT PAVEMENT

A REVIEW IS PRESENTED OF THE CONDITION OF A ROAD IN MADAWASKA, MAINE, PAVED WITH HOT BITUMINOUS MIXTURES CONTAINING 2% ASBESTOS. THE ASBESTOS FIBERS WERE INCORPORATED IN ORDER TO COMPENSATE FOR THE POOR QUALITY OF THE AGGREGATE IN THAT AREA OF THE STATE. THE ROAD HAS BEEN IN USE SINCE 1961 AND IS STILL IN GOOD CONDTION AFTER SEVEN YEARS IN SERVICE. A ROADWAY ADJACENT TO THIS PROJECT WAS RESURFACED AT THE SAME TIME USING THE CONVENTIONAL TYPE PAVEMENT. THIS ROAD HAS SINCE BEEN RESURFACED AGAIN AND AT PRESENT IT STILL IS NOT IN AS GOOD CONDITION AS THE ASBESTOS PAVEMENT. TESTS ON SAMPLES CUT FROM THE ROADWAY WITH ASBESTOS INDICATE THEY HAVE HIGH ASPHALT CONTENTS, HIGH DENSITIES, AND MINIMUM AIR VOIDS. THE PROPERTIES OF THE RECOVERED ASPHALT INDICATE, IN GENERAL, THAT THE ASPHALT IS STILL IN VERY GOOD CONDITION. /AUTHOR/
