TRANSITION ZONE STRUCTURE OF ASPHALT CONCRETE TRACK AND CONSTRUCTION METHOD THEREOF

摘要

The present invention relates to a transition zone structure of an asphalt concrete track for connecting tracks having different track structures like a transition zone for a concrete track and a ballasted track, and a construction method thereof for construction of an asphalt concrete track in a tunnel section or earthwork section. The construction method uses upper fastening devices having different rigidity and methods for gravel adhesion on a ballasted track and installation of reinforcement rails and asphalt layers to solve problems caused by different rigidity track connections of the asphalt concrete track, ballasted track, and concrete track. A double width rail tie or a concrete panel for a reinforcement rail is used as a rail tie for a reinforcement rail in a transition zone of an asphalt concrete track.;COPYRIGHT KIPO 2017
