ASBESTOS-CEMENT SLEEPERS

These Italian cross ties are manufactured by compressing a number of asbestos-cement sheets, interspersed with steel rods at very high perssure. The compression, flexure, and shearing strengths are given. Because of the material's intrinsic elasticity, a smooth ride results due to the reduction of rail hammer and hunting. Springs clips with rubber seating cushions and securing bolts with mushroom heads are used as the fasteners. The cross ties have operated satisfactorily under extreme climatic conditions and under heavy traffic.
