Purpose of the development: Construction technology durable asphalt layers of warm asphalt mixtures prepared with the solid hydrocarbons, is designed to improve the quality of the road surface and prolong the operation.

Recommended application field: Construction (Ministry of Infrastructure of Ukraine, the State Agency of Ukraine highways, spacecraft "Kievavtodor" design and construction organizations).

Advantages over analogues: Comparison with world analogues: meets world standards.

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: The economic attractiveness of development for market promotion , application and realization, parameters, price : A method of estimating the durability of asphalt layers of warm asphalt produced using solid hydrocarbons , as well as algorithms and programs for computer analysis - the nature of the interaction of temperature and the nature of phase transitions in model compounds bitumokompozitnyh materials. Economic effect obtained by reducing the energy consumption at the stage of preparation of asphalt mixtures due to the reduction of heating temperature of stone materials, bitumen , reducing effort during mixing bituminous mixture , by increasing the durability of asphalt layers with warm asphalt . Existing results of application : The research results are implemented in the design of reconstruction of the streets of Kiev : st. Vatutina , ave. Science , as well as in other cities of Ukraine.

Description of the development:
()
Character temperature reduction after laying the mixture affects the quality of the finished pavement , so changing the thermal properties of the mixture represents a significant scientific interest. So , it is advisable to apply the warm asphalt to extend the temperature range with the right to enter into mechanical and termoreologicheskimi characteristics that will ensure high durability . Scientific novelty and significance of the results is the development of technologies of building durable asphalt layers with warm asphalt using solid hydrocarbons , creating new methods for the study of technological parameters of the construction of asphalt layers and their longevity on the global level. Among them, the development of techniques to study technological regimes placement and compaction of warm asphalt mixes using the sector press technique to study the stability of the warm asphalt to the accumulation of plastic deformation at high cycle repeated loading at elevated temperatures at which asphalt is visco- plastic state . Patenting , competitive results : 3 obtained a certificate of copyright registration (№ 41995 , № 44255 , № 48068 ) . State of readiness of the development : the development of a pilot passed testing and implementation in practice of design , repair and construction of pavements on objects spacecraft " Kievavtodor ."
