Abstract:

Damping is a critical factor for the safe operation of passenger and freight shared track railway. Currently, three types of material are commonly used to provide the damping: (1) asphalt trackbed; (2) crumb rubber modified asphalt; (3) cement emulsified asphalt mortar (CEAM). CEAM possesses higher strength and modulus than asphalt mater ials but lower than those of concrete, which makes it more suited for ballast less railway construction than other materials. In Japan, China, and Europe, CEAM has been widely used in high-speed rail (HSR). However, little research has been conducted on CEAM in the U.S.
