茅坪溪土石坝沥青混凝土心墙最大设计高度94m，这是我国第一次采用心墙专用摊铺机施工；为确定合理的施工工艺参数，在正式施工前进行了系统的现场摊铺碾压试验，在此基础上制定了本工程的施工技术要求，包括施工准备，沥青混凝土制备、运输、铺筑及质量控制等等。
The maximum designed height of the asphalt concrete core wall of the Maopingxi earth-rock dam is 94m, which is the first time that the construction of a heart-wall paver is used in our country. In order to determine the reasonable construction process parameters, the system has been systematically in-site paved and laminated before formal construction Based on this, the construction technical requirements of this project were formulated, including preparation for construction, preparation of asphalt concrete, transportation, paving and quality control and so on.
