The shear behavior and drainage characteristics of coal-fouled ballast when treated with elastomeric polyurethane are assessed by means of large-scale direct shear and …
Contamination of ballast generally occurs due to particle breakage, infiltration of other undesired materials from the surface or base of the ballast is one of the primary reason for …
This paper presents a comparative study on the shear behavior of coal fouled polyurethane- stabilized and polyurethane-stabilized coal fouled ballast. Fresh ballast and coal fines of …
