摘　　要：温度应力是高温差地区引起道面破损的主要应力形式,通过在3种材料道面板纵、横两个方向不同位置布设应变计,测量了由温度变化引起的道面温度应变值,分析了各板块温度应力的变化规律,研究了温度对不同板块的影响情况和产生板块侧移及破坏的原因,为提高高温差地区水泥混凝土道面使用寿命提供了重要的理论支持。Among all stress that cause pavement destruction,temperature stress is the main factor in area where exists high difference in temperature.The paper designed a contrast experiment.The experiment measured pavement temperature stress of three kinds of material in vertical and horizontal and in different places.And the paper analyzed variation law of each plate＇s temperature stress,and studied environmental influences on different plates and reason for side move or destruction.The conclusions provide scientific basis for prolonging use life of airfield concrete pavement.
