Decarbonization Analysis and Sensitivity Research of Road Base with Plant Mixed Cold Recycling Technology
Based on the real data of construction organization and records,this paper establishes the life-cycle carbon emission calculation model,compares the carbon reduction between the scheme of plant mixed cold recycling technology and the alternative base scheme-traditional ATB-25 asphalt stabilized crushed-stone base,and analyzes the sensitivity of construction materials,carbon emission factors of energies,and the delivery distance.The results show that compared to the traditional ATB-25 scheme,the scheme of plant mixed cold recycling technology could reduce a large number of carbon emission from the production and mixture of mixed materials with a reduced rate of 21.1%.The decarbonization benefit is great.
