Construction quality control of skeleton dense structure cement stabilized gravel base in alpine and high altitude areas
Cement-stabilized gravel has high strength and stiffness,and good integrity,making it widely used in highway subbases.However,in high-cold and high-altitude areas,the special climatic conditions can lead to cracking and other diseases in cement-stabilized gravel bases.Skeleton-dense cement-stabilized gravel is more suitable for the climate of these regions.This paper focuses on the construction of skeleton-dense structure cement-stabilized gravel bases,analyzing potential problems in various construction stages based on the climatic charac-teristics of high-cold and high-altitude areas.It summarizes key points for controlling construction quality and i-dentifies new technologies and methods to address these issues,providing references for improving the quality of highway construction in high-altitude areas and extending the service life of the roads.
