Increasing the durability of pavement on bridge structures through the use of thin-layer coatings

Abstract

Road pavement is a key structural element for ensuring the safety and comfort of vehicles, in particular due to its flatness, low noise level and roughness, which guarantees the proper coefficient of adhesion to the tires of vehicles while driving. However, it should be noted that during operation, such a coating is easily exposed to negative factors that lead to its premature deformation.

In today's conditions of intensive development of transport infrastructure, the use of materials capable of ensuring the durability and reliability of pavements on roads and bridges is of particular importance. One of these materials is methyl methacrylate-based mixtures, which are becoming increasingly popular due to their exceptional performance properties. Methyl methacrylate mixtures provide high wear resistance, chemical resistance, fast curing and the ability to be used in various climatic zones. They also demonstrate excellent adhesion to various types of surfaces, making them particularly valuable for repairing and overlaying bridges and other complex structures.

However, in order to maximize the potential of methyl methacrylate-based materials, it is necessary to comply with the requirements for the quality of the initial components and the technology of manufacturing mixtures. Inadequate quality of raw materials or violation of technological processes can lead to deterioration of the pavement performance, its premature wear and the need for frequent repairs.

Asphalt concrete mixtures based on methy methacrylate resin with different types of aggregate (sand, screenings) were tested. The main task was to determine the physical, mechanical and thermo-rheological properties of the tested samples. The obtained results of the studies indicate the effectiveness of the use of asphalt mixtures based on methomethacrylate for use as a thin-layer pavement on road bridges.
