| Abstract: | The maximum dam height of Alagou pivotal project asphalt concrete core wall is over 105 meters with large work quantity and difficult work construction,and the asphalt concrete core wall needs to be constructed in winter,which means the construction quality control is the key,including material selection and ratio,mixing and transportation,warehousing and rolling,material test and quality inspection and other control links.This paper introduces the general technical requirements and practices for the construction of the RCC core wall,and emphatically describes the construction methods and measures of the asphalt concrete core wall in winter in the range of-20℃,which can be used as a reference for similar projects. |
