摘　　要：研究沥青混合料吸放热规律,对降低沥青路面温度提高抗车辙能力具有重要的战略意义.文中通过对现有3种类型、5种结构沥青路面吸放热规律进行研究,结果显示,不同类型路面结构吸放热特性存在差异:悬浮密实型结构绝热升温高;骨架空隙型吸、放热速度高;骨架密实型总储热量大.The paper Studies on Suction and exothermic law of asphalt absorb for reducing temperature of asphalt pavement and improving rutting-resistance of asphalt pavement have important strategic significance.This paper studies the suction and exothermic regular pattern of existing three types、five kinds of asphalt pavement structure.It turns out that there are differences in suction and exothermic characteristics of different types of pavement structure.Suspension close-grained type structure has higher adiabatic heating;gap-type skeleton has faster speed of suction and exothermic;and dense skeleton has more total quantity of heat storage.

关 键 词：沥青路面 吸放热特性 变化规律 储热量
