  • Large Direct Shear Tests Performed with Fresh Ballast

    This study evaluates the ballast shear strength from the testing of 20 specimens, performed in a very large direct shear box that has a shearing plane of 1 m by 1 m and can hold specimens with a thickness up to 80 cm. Tests comprise two different types of ballast (mylonitic and andesitic) and two different specimen preparation techniques (with and without compaction).

  • Testing of Contact Stress at Ballast Bed Soil astm

    As the interface stress between the ballast bed and the subgrade is a key factor in subgrade deterioration, new testing methods and numerical calculation methods can consider the discontinuous characters of the ballast appropriately to be necessary for the investigations of the interface contact stress.
