The Adaptability Analysis of Asphalt Pavement in Everfrost Area Under Heavy Load Conditions

Based on the current condition of asphalt pavement of Qingzang road,the article analyzes the five normal road pavement samples using finite variable models and conducts comparative analysis on their stress force response under different temperatures.The results show that pavement models with intermediate layer(ACR for example) have better adapta-bility.They also have lower vertical replacement,compression strain,maximum shearing strength,maximum shearing strain and tensilestress level.The article gives reference for the asphalt pavement design in areas with frozen soil.
