USE OF SPECIALLY BLOWN BITUMEN AS A BINDER FOR ROLLED AND GUSSASPHALT IN ROADS

ANWENDUNG VON SPEZIELL GEBLASENEM BITUMEN ALS BINDEMITTEL FUER WALZ- UND GUSSASPHALT IM STRASSENBAU

BECAUSE OF INCREASING DAMAGE IN THE SHAPE OF WEAR AND DEFORMATION TO ASPHALT ROADS, ATTEMPTS ARE BEING MADE TO IMPROVE THE AGGREGATES AND THE BITUMINOUS BINDER. RECENTLY SPECIALLY BLOWN TYPES OF BITUMEN HAVE BECOME AVAILABLE. THE PROPERTIES OF THESE PRODUCTS ARE TO BE TESTED AS IS THEIR EFFICIENCY IN PRACTICE AS A BINDER BOTH FOR ASPHALTIC CONCRETE AND GUSSASPHALT. AFTER A PRESCRIBED PERIOD OF OPERATION, INFORMATION IS TO BE OBTAINED ON THEIR SUITABILITY FOR ROLLED OR GUSSASPHALT.
