道面混凝土结构防冻胀措施研究OA

With the continuous development of modern building technology,the impact of concrete pavement structures on airport pavement traffic is becoming increasingly significant.In cold regions,the low temperature environment in winter poses a severe challenge to the perform-ance and service life of concrete pavement structures.At extreme low temperatures,concrete structures may experience frost heave,leading to cracking,damage,and decreased load-bearing capacity of the pavement.To address this issue,researchers have begun to focus on the study of anti freezing measures for concrete structures.The article studies the factors affecting the frost heave of pavement concrete structures,estab-lishes a frost heave model analysis,and proposes targeted solutions for reference.
