级配碎石垫层施工中的控制要点

On Control Points of Construction of Graded Macadam Cushion

垫层作为路面结构的组成部分,日益显现出其重要作用,它是路面和路基的连接纽带,其施工质量的控制尤为重要,因其直接影响工程质量的好坏。文章对垫层施工中原材料及施工过程中质量控制的关键要点进行了阐述,以其加强对垫层的质量控制,充分发挥其在路面结构层中的重要作用。

Cushion played an increasingly important part of the pavement structure. It links between pavement and roadbed. The quality control of construction of it is particularly important because it directly affects the engineering quality. The article analyzes the control of construction quality of cushion from raw and processed materials, construction technology and control of quality, which strengthens the quality control of cushion layer, making full use of it in the pavement structure layer.
