Development of an innovative mineral-asphalt blend produced in asphalt foam technology by the addition of zeolites
Reference number of the aid programme: SA.42799(2015/X), help_de_minimis: §42 of the Ordinance of the Minister of Infrastructure and Development of 10 July 2015 on the granting of financial assistance by the Polish Agency for the Development of Enterprise under the Operational Programme Intelligent Development 2014-2020. The subject of the project is the development of an innovative mineral-asphalt mixture produced in the technology of asphalt foamed by the addition of zeolites. The new product – a mineral-asphalt mixture, which can be used for asphalt paving at a lower incorporation temperature, will constitute a product innovation in Poland. The technology based on the use of synthetic zeolites produced from volatile ashes for the production of mineral-asphalt mixtures has not yet been used on the Polish market. The innovative product will be characterised by a reduction in the temperature of production, incorporation and compaction of mineral-asphalt mixtures and increased quality parameters compared to the currently used hot mixtures. The scope of the project includes: 1. Determination of types of zeolite structures which, due to their properties, allow their optimal use in the process of foaming asphalt. 2. Assessment of the effect of the addition of zeolite materials on the properties of asphalt binders. 3. Preparation of recipes of mineral-asphalt mixtures produced in the process of asphalt foamed by the addition of zeolites. 4. Carrying out laboratory tests for the use of zeolites as an additive for asphalt foaming in mineral-asphalt mixtures and assessing the quality parameters of the produced mixtures. 5. Technological tests under real conditions – production of mineral-asphalt mixture produced by the asphalt foam technology by the addition of zeolites. The result of the work submitted to the applicant by the scientific unit will be the technological documentation for the production of the mineral-asphalt mixture (MMA) produced in technolo
