The Qinshen Railway Passenger Dedicated Line, the Beijing-Tianjin Intercity Railway, and the Wuhan-Guangzhou Passenger Dedicated Line and the Beijing-Shanghai High-speed Railway under construction have all adopted the slab ballastless track technology. Cement emulsified asphalt mortar is an elastic filling between the track plate and the concrete base. The spacing is adjusted to have a buffer effect on the high-speed train. Therefore, the cement emulsified asphalt mortar production quality and perfusion quality have an important impact on the construction of the ballastless track railway.
