Research on Construction Technology of Subgrade and Pavement in Settlement Section of Asphalt Concrete Highway
In this paper,the whole construction process of roadbed and pavement in settlement sensitive section of asphalt concrete highway is discussed.This paper first analyzes the key technologies in the construction preparation stage,including the selection of fillers and the optimal configuration of construction tools,in order to ensure that materials and equipment can meet the needs of high engineering standards.In the subgrade treatment and pavement laying process,the use of precise automated paving technology and scientific compaction strategies is ex-plored,aiming to ensure the smoothness and thickness consistency of the road surface,and reduce the cracks and uneven settlement that may occur during the curing process of the material.Finally,the ground subsidence meter and horizontal displacement observation device are used to monitor the immediate performance of the pavement and predict its performance change under long-term use,verify the effectiveness of the adopted technology,and demonstrate how to minimize the subgrade settlement and optimize the pavement performance through technological in-novation,in order to provide scientific reference for the settlement section construction of asphalt concrete highway.
