THE STUDY OF INFLUENCE THAT INTRODUCTION OF MODIFYING ADDITIVES HAVE ON PHYSICAL AND ECONOMIC PROPERTIES OF ASPHALT CONCRETES
Keywords:
silica clay, mineral supplement, adhesion, bitumen, asphalt concrete mixture, pH valueAbstract
The results of studying the influence of silica clay as a mineral additive of natural origin on the pH value of asphalt-concrete mixture and on the adhesive properties of bitumen correspondingly are presented. An assessment of economic effect from using the additive (silica clay) in comparison with standard asphalt-concrete mixture with the use of the MP1 standard mineral additive produced at the MUP "Specialized Road Enterprise" of the city of Kurgan is carried out. It is determined that due to the use of the mineral additive made of silica clay, which is much cheaper than the mineral additives used in production of asphalt concrete at the moment, we managed to reduce the cost of the asphalt concrete mixture and improve the basic physical and mechanical properties.
