  • The Effect of Fouling Materials on Permeability

    In the cases where the shoulder ballast is fouled to more than 50% VCI, it is seen that the drainage is classified as ‘poor drainage’ even if the other ballast layers are relatively clean. Therefore shoulder ballast layer should be cleaned or replaced to maintain an acceptable drainage capacity when it reaches 50% VCI.

  • Various Methods of Ballast Cleaning and Renewal AREMA

    Depth of cleaning depends on the amount of ballast under the ties. To do a perfect cleaning job all of the ballast should be cleaned. Since this is not a practical procedure, as much of the ballast as possible should be cleaned without damaging the stability of the track. The shoulders should be cleaned to the level of the subgrade.

    The ballast shoulder should extend horizontally from the sleeper end. It is, however, acceptable for the ballast shoulder to be profiled in the plane of the sleeper for a normal ballast shoulder width (nominally 400mm) to suit ballast regulators. Any extended shoulders, such as on bridges, should be horizontal.
