ADHESIVE QUALITIES OF BITUMINOUS BINDERS TO AGGREGATES IN ROAD BUILDING AND HYDRAULIC WORK

A WIDELY-KNOWN METHOD OF IMPROVING THE ADHESIVE QUALITIES OF BITUMINOUS BINDING AGENTS TO AGGREGATES FOR ROAD BUILDING AND HYDRAULIC WORK CONSISTS OF INCLUDING SURFACE-ACTIVE ADDITIVES IN THESE BINDERS. A MORE UP-TO-DATE METHOD PROVIDES FOR INTRODUCTION OF THE ADDITIVES BY DIRECT APPLICATION ON THE INTERFACE BETWEEN THE CEMENTING SUBSTANCE AND THE AGGREGATE. THE FIRST PART OF THE PAPER REVIEWS THE TECHNICAL AND ECONOMICAL ADVANTAGES OF THIS NEW METHOD. LAB TESTS, ENABLING AN EVALUATION OF THE PRODUCTS EFFICACY IN VARIOUS APPLICATIONS, ARE DESCRIBED AND DISCUSSED. IN THE SECOND PART, THE RESPECTIVE INFLUENCE OF THE VARIOUS FACTORS PERTINENT TO THE BINDING AGENTS (VISC, ORIGIN) AND THE AGGREGATES (CHEMICAL COMPOSITION, PERCENTAGE OF FINE AGGREGATE, POROSITY, SPECIFIC SURFACE) ON THE EFFICACY AND ECONOMY OF THE METHOD ARE EXAMINED. CONCLUSIONS ARE DRAWN POINTING IMPROVEMENTS IN PRODUCTS AND APPLICATIONAL TECHNIQUES.
