摘要
介绍沥青的胶体结构及其感温性能机理,指出沥青在加热过程中温度控制的重要性,提出沥青老化行进性观点。阐述沥青混合料加热拌和过程和温度失控对沥青质量的影响,提出沥青混合料在加热拌和过程中温度控制要点和沥青摊铺的保温措施。
This article briefly introduces the colloid structure of asphalt and its temperature induction mechanism, and points out the significance of temperature control on asphalt in the temperature elevating process. For the first time it puts forward a concept of aging advance of asphalt. It explains the heating blend process of asphalt mixtures and indicates the influence of losing control of temperature on asphalt quality. It also illustrates the main points of temperature control on asphalt in the temperature elevating blend process and heat preservation measures.
