CONCRETE PROPERTIES IMPROVEMENT OF SLAB TRACKS USING CHEMICAL ADDITIVES
, 2015 Purpose. On the Railways of Ukraine a very large number of slab tracks are operated with cracks. Many scientific works of previous years are dedicated to improving the design of slab tracks. The main causes of defects are: poor exploitation of the track;

Interlayer Cracks Evolution in Slab Ballastless Track Based on Acoustic Emission Technology
Chengshi guidao jiaotong yanjiu［Objective］ Slab ballastless track is a typical layered structure system, and the bonding state of its interlayer interface directly affects the safety of train operation. Therefore, it is necessary to study the interlayer evolution of slab ballastless track by combining micro and macro methods. ［Method］ Concrete-mortar composite specimens are made and
