Econstone comes from the existing pavement. Consists of gravel, aggregate, bitumen and sand. It is milled to a size 0 ---- 31.5 mm or the size requested. Econstone is often used as a sub-base for pavement construction. Eco stands for ecological sustainable, because: * "Replaces new mineral, meaning that the original minerals in the areas of origin, be preserved." * "Reduce CO2 emissions if the material is used in sub-bases, as this will reduce the preparation of hot asphalt for the top layer. This means less production of asphalt plants, thus lower emissions. Economically perhaps Econstone because it is cheaper than traditional gravel. The stabilization Econstone is a frequent application of the granules. For purposes of stabilization, Econstone can be mixed with cement, bitumen emulsion, bitumen foam or other binding agent. The sub-bases to have stabilized to improve the quality of the pavement and one of the advantages is that you can apply thin layers of hot asphalt preparation (expensive) to achieve the same quality of construction. Therefore, we can achieve significant savings with regard to raw materials, construction costs, tax processing and pollution (CO2). Econstone means a saving when used as sub-base preparation of asphalt (hot) to the upper layer. Econstone is certified by the EC in accordance with NEN EN 13242 (Aggregates for hydraulically bound materials for use in civil engineering and road construction).
