Abstract:Under the background of the national double-carbon goal, all industries are actively exploring the innovation path of green environmental protection and sustainable development. In the engineering construction industry, various green technology innovations are competitively carried out to enhance the environmental protection and low-carbon nature of the project. Taking a highway project as an example, by trying the application of new materials and new processes, the practical research on the technical scheme of building recycled material to solidify and stabilize the soil bottom base is carried out. The test results show that the average deflection of the solidified stable soil section of the building recycled material is 56.9 (0.01 mm), much smaller than the 93.1 (0.01 mm) of the ordinary solidified stable soil section. The economic and technical analysis also shows that the solidified stable soil subbase of building recycled materials has the obvious price advantages, and is 30~40 yuan/m3 lower than the unit price of cement stabilized gravel, which can not only significantly reduce the engineering cost, but also simplify the construction procedures and effectively shorten the construction period. Therefore, this technology is an environmentally friendly, low-carbon, simple construction, economical and reliable technical scheme, and has certain application value. The research results are expected to expand ideas and accumulate experience for the green transformation of road engineering construction.
