Abstract

Asphalt concrete tracks are excellent in terms of workability and economy, and have the advantage of improving running stability and easy maintenance. However, because it is constructed on site in the buttom-up method, methods for precise construction are required. The composition of the asphalt concrete track system can be divided into subgrade installation, asphalt concrete ballast installation, track installation, and vertical and horizontal resistance equipment, Management through guide wire and measurement is required to secure the precision of each process. If studies to increase precision are continuously promoted through these field installation studies, it will contribute to the technological development of asphalt concrete tracks.
