Book Description

The report concludes formal evaluation of forty-one experimental high-type railroad-highway grade crossing surfaces installed throughout Louisiana between 1970 and 1984. These crossings were composed of various types of rubber, high-density polyethylene, precast concrete or steel plate construction and were installed under varying ADT situations. Six interim reports profiled construction techniques, durability of proprietary surface crossing materials, rideability characteristics, effectiveness of drainage, track rehabilitation procedures and included statistical rail and traffic data. Performance evaluations were conducted examining criteria necessary for establishing departmental policies, procedures and specifications with regard to railroad-highway grade crossings and determining the materials' suitability for inclusion on the Qualified Products List.
