Abstract
The need for formation of prices for road construction works producing, by using composite of cationic bituminous structures, is dictated by absence of this type of work in estimate-normative base, due to the fact that this type of materials had never been used before. Estimated specifications could be used either for determination of work cost or for substantiation of efficiency of using new type of materials. This paper provides basic concepts, related to formation of estimate-normative base for determination of construction and installation works cost, particularly road construction works, also it shows formation of coating installation prices by using composite of cationic bituminous emulsions.
Highlights
Modern system of estimated specification is the foundation of definition of construction and installation works cost, road construction works cost
The development of estimated specification for road constructing work production with using composite cationic bituminous structures is determined by advantages of this material over traditional technologies of hot and cold road asphalt paving: 1. There is no need in adherence to temperature conditions, due to the fact that this method can be used either in worm or in cold weather conditions
This paper shows the process of formation of prices for road construction works with using composite cationic bituminous structures, and gives a comparison of work costs for road covering installations with using new materials and traditional methods of hot and cold asphalt-concrete mixtures
Summary
Modern system of estimated specification is the foundation of definition of construction and installation works cost, road construction works cost. Current system can’t cover the whole spectrum of modern constructive materials, new materials that had never been used before in constructing or in other definite type of works. The development of estimated specification for road constructing work production with using composite cationic bituminous structures is determined by advantages of this material over traditional technologies of hot and cold road asphalt paving: 1. The repairing of road cover can be produced in high humidity conditions at positive ambient temperatures [1, 9]. 2. You can exploit roads 2 hours after finishing repairing works, which is especially actual on increased workload roads [2, 6, 11]. The value of bitumen using is highly reduced compared to hot and cold asphaltconcrete mixtures structure [1, 9]
