AAR LABORATORY INVESTIGATION OF PROPOSED AREA BOX BEAMS AND EPOXY RESIN SHEAR KEYS

Report is made of an investigation on four full-size prestressed concrete box beams constructed according to proposed AREA specifications for use with concrete trestles. Purpose of the investigation is to study the performance of beams under static and repeated loading before recommending them for Manual material. Due to tensile cracking, the original test beams were considered objectionable for railroad use, and the beams were redesigned to eliminate the condition. Load tests are applied to the new beams, and repeated loads in excess of the cracking load are proposed.
