Reporters from the March 1st meeting of the Shanxi provincial highway work meeting was informed that: the completion of construction investment of 4100000000 yuan in the last year, based on the construction of highway 527.3 kilometers, this year, the province plans to invest vertical roller mill 3000000000 Yuan to build 300 kilometers of trunk road, and constantly improve the comprehensive service level of road network.
This year's work in highway construction, will complete the transformation of 35 dangerous bridge, highway 500 km rural road maintenance, vertical roller mill machine completed an investment of 1500000000 yuan, the streets hardening projects completed investment of 7000000000 yuan, the construction of village streets sclerosis with full coverage.
At present, in the road construction, the fly ash with cement or lime by proportion, as paving material of highway subgrade layer, vertical roller mill has the characteristics of high strength, low compressibility, consolidation fast.
The use of industrial waste fly ash in road construction can not only save the fine aggregate, and it is of great benefit to Protect environment. At present, the technology has been more than 200 fly ash in China, of which there are more than 70 mature technology, which is widely used in road engineering, production of building materials, construction engineering, fertilizer, soil improvement etc..
The mixture of fly ash after a certain period of time hard, showing a good plate body, water stability and a certain frozen stability, can effectively shorten the construction period, reduce the settlement of road surface, the current highway construction in other provinces have been widely used in.
The wide application of fly ash in highway construction, the technology is feasible, has a very positive and practical significance. At the same time, the extensive use of fly ash in highway construction, is to protect the ecological environment, turning waste into treasure, turned into a good thing, for the benefit of society, is in line with the implementation of Kexue Fazhan Guan, to promote circular economy strategy. Technology of vertical roller mill powder processing equipment ash, environmental protection, low noise, little dust, clean operation environment, product quality is stable, particle size uniform, easy and reliable operation, simple repair operation, high efficiency, low operation cost, welcomed the consultation!
