Mix for building a road surface and method for producing it

摘要

the object of the application is a mixture of bituminous - rubber - asphalted road surface construction and way of producing.the mixture for the construction of road surface is characterised by having granules of the asphalt uziarnieniu 5,6 to 11.2 mm, in quantities of from 95 to 99% by weight preferably 98,8%the rubber granules diameter 3.0 mm, preferably 1.0 mm in quantities to 1,0% by weight preferably 0,18%, bazaltowo - polymer fibre length from 10 to 20 mm, preferably 12.5 mm in quantities of up to 2% in weight, preferably 0.6%, quartz sand of uziarnieniu 0,2 to 1,0 mm, preferably 0.4 - 0,8mm of 0,1 to 0,5% by weight, preferably 0.2% asphalt 50 / 70 in amounts from 0.6 and 1.2% by weight preferably 1.0%. advantageously, when the fibres bazaltowo - polymer length equal to 1 - 1.5 the greatest dimension of the grains.advantageously, the fibres bazaltowo - polymer consists of fibres bazaltowych coated polymer in quantities of 75% by weight of aramidowych 25% by weight.object of the application is also the manufacture of compound for the construction of the road surface, which is characterized by the fact that after mixing in the gas mixing piece of the asphalt.quartz sand, granular rubber is heated to the temp.in the process of dispersing 150u00b0c after adding the fibre bazaltowo - polymer and asphalt type, 50 / 70 are mixed and heated to temp 180 - 200u00b0c subjected to adsorption process during the 15 minadvantageously, the aramid fibres and the process runs in known manner.
