Abstract
The use of activated rubber chips in the reconstruction of the upper part of overpasses and the roadway of bridge structures
Incoming article date: 01.02.2025Intensive wear of the road surface under the influence of traffic loads, climatic factors and structural features of bridges has increased the number of studies in this area. One of the promising areas for improving the operational reliability of bridge structures is filling asphalt concrete mixtures with activated rubber chips, which are highly resistant to wear and mechanical damage. Both traditional paving technologies using polymer-composite mixtures and modern technologies using asphalt concrete filled with activated rubber chips are considered. The advantages of using recycled rubber, which increases the traction properties, wear resistance and durability of the road surface, are considered. A comparative calculation of the cost of pavement reconstruction using the compared technologies was carried out, which showed a significant reduction in the cost of materials and laying asphalt concrete with activated rubber filler compared with polymer composite coatings.
