In order to prolong the lifetime and to improve the quality of pavements made of asphalt concrete it is necessary to apply innovative solutions in the process of design of such building materials. In order to solve the problem of low durability of asphalt concrete a modifier was proposed, which consists of diatomite, iron hydroxide sol (III) and silica sol. Application of the diatomite with nanoscale layer of nanomodifier allows getting a stone mastic asphalt, which has high values of physical and mechanical properties and allows refusing from expensive stabilizing additive. Mineral filler was replaced by diatomite, which has been modified by iron hydroxide sol (III) and silica sol. Modified diatomite allows sorption of bitumen and increase the cohesive strength and resistance to shear at positive temperatures. The modified asphalt has higher resistance to rutting at high temperature, abrasion resistance at low temperature and impact of climatic factors: alternate freezing and thawing, wetting-drying, UV and IR radiations. It is achieved by formation of solid and dense bitumen film at the phase interface and controlling the content of light fractions of the bitumen. The modifier consists of sol of iron hydroxide, which blocks the oxidation and polymerization of bitumen during operation. The proposed material allows controlling the initial structure formation of stone mastic asphalt. It was shown that modern test methods allow assessing the durability of asphalt in the design phase compositions.

Subject: technical and economic efficiency of the use of nanomodified porous mineral powder in the composition of asphalt-concrete mixture. The system of quality indicators of crushed stone-mastic asphalt-concretes obtained using nanomodified porous filler is presented. A general criterion for the quality of asphaltic concrete and a method for assessing the technical and economic efficiency of the use of nanomodified filler to control the properties of asphalt-concrete have been developed. Using the methods of system analysis, decomposition of the asphalt-concrete quality system was carried out and the basic quality indicators and dependencies for calculation of particular quality criteria were identified. The efficiency of using a filler based on a porous mineral material whose surface is modified with an additive based on iron hydroxide sol and silicic acid is shown. Research objectives: substantiation of effectiveness of the use of nanomodified porous mineral powder in the composition of asphalt-concrete mixture, taking into account the efficiency and cost criteria. Materials and methods: oil road bitumen BND 60/90, gabbro-diabase crushed stone of 5-20 mm fraction, granite crushing and screening products, stabilizing additive Viatop-66 and nanomodified diatomite were used. Samples of crushed stone-mastic asphalt-concrete were tested in accordance with the standard methods, and resistance to varying weather and climatic conditions and also rutting resistance were studied. Results: the proposed criteria allow one to estimate the effectiveness of the use of nanomodified mineral powder in asphalt-concrete, taking into account both the technical characteristics of the asphalt-concrete, obtained by using the powder, and the economic costs necessary to achieve improvement in quality indices. Concrete SMA-20, in which 100 % of the traditional filler is replaced by a powder based on diatomite, modified with iron (III) hydroxide sol and silicic acid, has a 28 % higher technical and economic efficiency compared to traditional crushed stone-mastic asphalt-concrete. This is achieved by significantly improving the quality of the material compared to the necessary ones. Conclusions: the use of the powder based on diatomite, modified with the iron (III) hydroxide sol, and silicic acid as a filler in the composition of asphalt-concrete mixture makes it possible to increase the asphalt-concrete efficiency index by 35 %. The increase in technical and economic efficiency by 28 % justifies application of the modified filler.
