Abstract
This paper studies the transformation technology of highway permanent and temporary structure based on the concept of low carbon,aiming to solve the problems of resource waste and high carbon emissions caused by the independent design of temporary road and permanent pavement in traditional highway construction.Through the integrated design,the technology organically combines the temporary road with the permanent pavement,and adopts the"rigid flexible"or"rigid semi-rigid flexible"composite structure system,which significantly improves the pavement durability and reduces energy consumption and carbon emissions.Based on the principle of coordinated deformation of permanent and impending structures,the performance parameters of semi-rigid materials are optimized,and the concept of"deformation gradient control layer"is proposed,which effectively alleviates the problem of incompatible deformation.Through quantitative analysis,the energy saving rate and emission reduction rate of the technology in the material production stage reached 26.8%and 25.6%,respectively.During the construction phase,the energy saving rate reached 40%,and the emission reduction rate reached 35.7%.The measured data are consistent with the simulation results,which verifies its significant low-carbon performance.This technology provides a new technical path for the sustainable development of highway construction industry.关键词
