THE USE OF RUBBER CRUMB IS FOR MODIFICATION OF BITUMEN

Iryna Mirchuk Artur Onyshchenko Ievgen Plazii

The main reason for the destruction of road wear layers is the loss of structural connections in the material of asphalt concrete layers, which is largely due to the low quality of bitumen. In order to improve the properties of binding materials, composite binders based on bitumen and modifiers are used in foreign and domestic practice for the installation and repair of road surfaces. One of the ways to improve the properties of asphalt concrete is the use of modifiers based on rubber crumb obtained from car tires that have lost consumer properties, as well as other rubber products. The problem of using tires is also of great environmental importance. Used products accumulate in places of operation (car parks, airfields, industrial enterprises, etc.). In addition, tires have a high fire hazard, and products of uncontrolled combustion have an almost irreversible impact on the environment. The paper presents a domestic and foreign analysis of the use of rubber crumb to modify bitumen in order to improve the physical and mechanical indicators of road wear. Asphalt concrete coating on transport facilities, which includes bitumen, is subject to significant influence of adverse factors (precipitation, change in environmental temperature, load from motor vehicles, etc.), which reduce its durability. Modification of road bitumen is one of the promising ways of increasing the durability of asphalt concrete pavement on artificial structures. Since the rubber crumb has an organic affinity with the components of bitumen and the physical and mechanical interaction gives a homogeneous material with significantly different characteristics from the original material
