EVALUATION OF BITUMEN AND BITUMINOUS MIXTURES IN RELATION TO PAVEMENT PERFORMANCE

THE RESULTS OF VARIOUS INVESTIGATIONS CARRIED OUT WITH THE OBJECT OF EVALUATING BITUMEN AND BITUMINOUS MIXTURES ARE GIVEN THE CAUSES OF PAVEMENT FAILURE IN COLD CLIMATES WERE STUDIED IN FIELD TESTS AND SOME FACTORS WHICH AFFECT PAVEMENT PERFORMANCE WERE FOUND. THE DOMINANT FACTORS PROVED TO BE ABRASION, CRACKING, DISINTEGRATION ECT. THE STUDIES SHOWED THAT SPECIAL ATTENTION SHOULD BE PAID TO THE RAVELLING AND BRITTLENESS OF BITUMEN AND BITUMINOUS MIXTURES. THE CHARACTERISTICS OF VARIOUS TYPES OF BITUMENS AND BITUMINOUS MIXTURES WERE ANALYZED, AND THEIR RELATION TO FIELD PERFORMANCE WAS STUDIED. AT THE SAME TIME THE RAVELLING MACHINE WAS DEVELOPED. THE RELATION BETWEEN THE ABRASION OF VARIOUS TYPES OF MIXTURES AND SOME FUNDAMENTAL CHARACTERISTICS OF BITUMENS WAS INVESTIGATED. BRITTLENESS AND FLEXIBILITY WERE ALSO TESTED. FIELD AND LABORATORY TESTS SHOWED THAT THE PENETRATION INDEX IS ONE OF THE MOST IMPORTANT FACTORS THAT INFLUENCE PAVEMENT PERFORMANCE AT LOW TEMPERATURE. /RRL/A/
