REQUIREMENTS FOR METHYL METHACRYLATE-BASED MIXTURES: APPROACHES TO QUALITY ASSURANCE

The article presents the requirements for polymer mixtures made on the basis of methyl methacrylate for the arrangement of thin-layer pavements of the bridge deck. The pavement on bridges is an important structural element of the structure, the condition of which affects the overall safety of the entire structure. Given the constant increase in traffic volume and the load on the street network, to increase the durability of road sur-faces, materials should be used that guarantee reliable operation of the roadway of bridge structures. Road pavement is a key structural element for ensuring the safety and comfort of vehicular traffic, in particular due to its flatness, low noise level and roughness, which guarantees proper adhesion coefficient with the tires of vehicles while driving. However, it should be noted that during operation, such a pavement is easily exposed to negative factors that lead to its premature deformation. In order to maximize the potential of materials based on methyl methacrylate, it is necessary to adjust to the quality of the output components and the technologies for the preparation of sums. Unsatisfactory moisture or disruption of technological processes can lead to deterioration in the performance characteristics of the coating, its immediate wear and need in some repairs. Methyl methacrylate compounds demonstrate excellent performance characteristics, such as hardness, high wear resistance, resistance to the infusion of aggressive media and excellent adhesion to different surfaces.
