Paving Technology for Asphalt Pavement Under Low-temperature Environments
According to the seasonal characteristics of northern cities in China,the pavement construction technology of asphalt mixture surface layer was studied under low temperature environment.Combined with the comprehensive traffic control project of Beijing Central Business District(CBD),based on the characteristics of ambient temperature and asphalt mixture materials,the various links of pavement construction were explored to propose the pavement construction technology and organization scheme,including personnel organization,material preparation,mechan-ical construction,inspection well reinforcement,kerb quality control,environmental protection measures,temper-ature monitoring and acceptance guarantee.Through monitoring the temperature of materials and the various indica-tors of the pavement after the construction,the effectiveness of the scheme was verified.The temperature monitoring results show that the scheme effectively controls the temperature of asphalt mixture during the construction,paving and compaction.Even in the case of significant drop of ambient temperature,the construction temperature is guar-anteed;The acceptance test results show that the scheme effectively guarantees the construction quality.The con-struction technology and organization scheme is suitable for the pavement construction under low temperature envi-ronment which effectively guarantee the quality and efficiency of the pavement construction.
