Changing the ratio between the large (size 5… 10 mm) and the small aggregate in the composition of the concrete leads to a change in the density of the packing of the aggregates, changes the coefficient of sliding of grains of crushed stone soluble part and the average density of concrete. Based on the calculations of the technical and economic efficiency of the use of the polymeric SBS modifier, it was found that the increase in the cost of such mixtures is not compensated by the increase in the service life of the coating. However, due to the possibility of reducing the thickness of the layer, the use of asphalt mix with 5% polymer modifier is economically feasible.  Product Description popup.authors Efremov Sergiy V.
