The Standard deals with squared, prestressed, reinforced concrete crossties for wide-gauge railroads, standard rolling stock, rails of the P50, R65, and R75 types, and for intermediate rail fastenings of the KB and ZhB types, on straight and curved track sections (with a radius not less than 350 m). The shapes, basic dimensions and types of crossties have to conform to drawings on Table 1. There are two sorts of ties, I and II, according to their quality. Admissible deviations from standard dimensions are given in Table 2. The sloping of the under-tie area has to be 1/20 (within limits for tie I of 1/19 to 1/20, and for tie II of 1/19 to 1/22). Technical specifications and GOST requirements for various types of aggregate, the quality of Portland cement, mechanical stresses in ties, and all construction equipment are described. Acceptance rules and testing methods are described, as well as transportation, marking and storing methods.
