  • A Review Of Methods For Estimating Ballast

    A Review Of Methods For Estimating Ballast

    Changes to the bulk ballast electromagnetic EM properties in turn affect GPR wave travel times, reflection strengths, and signal attenuation, while changes in air void size can directly impact the scattering behavior of GPR waves as they propagate through the ballast.

    Characterization Of Rail Track Ballast Fouling Using

    2013-12-5ballast or a capping layer placed above the formation soil. Ballast is a coarse granular medium usually hard rock ballast placed above the sub ballast and below the rails. The loads from the sleepers are distributed to the sub ballast and compacted earth through the main ballast section. A rail ballast bed acts as the main foundation.

  • Assessment Of Railway Track Substructure Condition

    Assessment Of Railway Track Substructure Condition

    Abstract. Ground penetrating radar GPR has been employed to assess railway track substructure ballast, subballast, and subgrade conditions. GPR involves transmitting radar pulses into the substructure and measuring return signals that have reflected off boundaries between substructure layers with different electromagnetic properties.

    Iet Digital Library Characterisation Of Ballast Materials

    In recent years the use of high frequency GPR antennas such as the 2GHz horn antenna have become popular for railway trackbed evaluation due to their ability to help determine the extent of fouling within the ballast layer. Fouling of the ballast affects both its strength and drainage properties. The theory is based on the scattering behaviour of GPR signals in an inhomogeneous media.
