Composite Railroad Ties - RTI's PermaTie Facts

RTI's clientele currently includeds Class l Freight, Regional, Local Short Line and Transit railroads, Maintenace of Way contractors and the U.S. Department of Defense.

RTI's PermaTie^TM composite ties have been continuously tested on Transportation Technology Center's railroad test track for over 830 MGT and surpass all prescribed AREMA and ASTM standards for engineered composite railroad ties.

MOR, MOE and accelerated weathering and aging tests were performed on RTI's composite railroad ties at University of Illinois by Poo Chow, Ph.D.

Unlike chemically treated wood ties, spike pullout resistivity increases over the life of PermaTie^TM crossties.

PermaTie^TM composite ties are completely compatible with wood tie rail systems.

Unlike chemically treated wood crossties, PermaTie^TM composite railroad ties do not conduct electricity. PermaTies^TMhave virtually no moisture content, and although they possess AREMA compliant strength, PermaTies^TM do not rely upon any conductive steel or concrete components for structural strength as do some other composite ties. PermaTies^TM are electrically non-conductive thereby diminishing railroads' problems with stray current corrosion and interference with proper track circuit and signalling operation.

Unlike other composite ties, PermaTie^TM composite crossties do not require any pre-drilling of holes prior to spiking (cut or screw spikes) and do not/will not crack or split during any type of conventional mechanical or manual spiking.

All PermaTies^TM are numerically serialized, and tested at intervals for quality assurance.

PermaTie^TM engineered ties are made exclusively with quality, UV protected, recycled plastics and a common mineral filler; no other miscellaneous fillers or extraneous ingredients.
