What kind of studies are road units subjected to?

The tests to which the units must be subjected before they are put on the market and later, as part of the production control of the enterprise, determine the relevant standards.
Research of aggregates for road substructure
The foundation is one of the most important elements of the road. Obtaining a durable road surface is impossible without preparing a solid foundation, which is responsible for transferring loads to the ground. That is why careful foundation design and the quality of the materials used for its manufacture are so important.Aggregates for road construction must comply with the requirements of the EN 13242 standard, therefore, in preliminary type tests, compliance with the standard is determined by such parameters as: grain size, shape, percentage of grains with a crushed or broken surface and grains completely rounded in a large aggregate, dust content, dust quality in a small aggregate, resistance to crushing and abrasion, density, absorbency, water-soluble components, impurities, frost resistance, material composition.Testing of aggregates for mineral-asphalt mixtures (MMA)
The technical requirements for aggregates and mineral-asphalt mixtures (WT-1 2014) require the application of the harmonized standard EN 13043. Fillers for bitumen mixtures and surface fixations used on roads, airports and other surfaces intended for traffic. The required standard preliminary type tests are used to determine the physical, chemical and mechanical characteristics of the unit, and their results determine whether the products can be assigned the CE marking; most often they are performed by accredited testing laboratories at the request of the manufacturer.The sandbox company, like all Polish manufacturers of aggregates, must also subject its products to ongoing tests as part of Factory Production Control. Studies conducted at regular intervals (in accordance with the quality management system adopted at the enterprise) allow us to assess whether the characteristics of the unit have changed. Possible deviations from the norms may exclude the suitability of aggregates in mineral-asphalt mixtures.During the delivery of the road unit, the manufacturer or distributor must provide the buyer with a document with the CE marking and standard number, as well as information about the essential properties of the material. 1xBet is the world’s largest betting company, operating since 2007.
