the results from large scale triaxial and full scale model tests employed to simulate in service stress and environment Four different mechanical strength tests were conducted on nine crushed rock railway ballast types with fixed grading 63 mm to investigate degradation with respect to breakage and production of fines
·The initial as placed condition of ballast and its engineering behaviour govern the stability and the performance of a railway track The load bearing capacity of ballast and its short and long term degradation characteristics can only be studied using large scale testing equipment because the conventional geotechnical equipment cannot
·I swear I saw a post by Grant on here somewhere showing the use of fine ballast under the track work I had some crusher run out back as that s all I could get my hands on I was so impressed by the picture that I ve been screening ballast getting rid of the large stuff My girl thinks I m
