Laboratory Investigation of Type I and Type II Hardened Cement Emulsified Asphalt Mortar [PDF]

open access: yes, 2014
The research presented in this thesis investigated the mechanical and viscoelastic properties of a relatively new construction building material that has been given a lot of attention in the past decade. Cement emulsified asphalt mortar (CEAM) has unique

CONCRETE PROPERTIES IMPROVEMENT OF SLAB TRACKS USING CHEMICAL ADDITIVES

open access: yes, 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

open access: yesChengshi 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

The assessment of track deflection and rail joint performance [PDF]

open access: yes, 2018
Track stiffness is the one of the most critical parameters of the track structure. Its evaluation is important to assess track quality, component performance, localised faults and optimise maintenance periods and activities.
