The ballast density is one of the principal parameters for roadbed operating state. It greatly affects the railroad stability, the accumulation of railroad residual deformation and the amount of work for railroad maintenance. SM-1 ballast density gauge is designed to determine the density of ballast by using the effect of (gamma)-ray passed through the ballast. Its fundamentals, construction, specifications, application and economic profit are described. (Atomindex citation 23:075461)
