Abstract

Stone ballast plays an important role in ballasted track of railway.Ballast density and resistance are an important parameter for the analysis of track structure and it has close relations with rapid deterioration of the quality of the track geometry as well as the amount of work in railway track maintenance.Ballast density and resistance are more incumbent on the stability of tracks in Qinghai-Tibet railway under frosty conditions with big difference in temperature.In the paper,the methods of test and analysis on the data of ballast density and resistance were described.There are useful references to tests of ballast resistance.The results show that the data of ballast density and resistance can meet the requirement of the relative criteria by adopting reasonable construction technology and method.
