Design Characteristics

Composite rail tie is a true composite structure, integrating desired properties from its various components to generate a "sum better than its parts". The design of the rail tie includes a plastic mixture reinforced by a rectangular wood beam. The outcome is a railroad tie with enhanced carrying capabilities, longevity, crack resistance, and insect resistance.
The Plastic Component
Recycled Composite technology facilitates the processing of various plastic materials without separation or special cleaning. One of the components is a form of cross-linked polyethylene, providing thermal and chemical stability, as well as inherent UV degradation resistance.
The overall performance of the plastic component is characterized by enhanced crack initiation and propagation resistance at all field temperature ranges, including subzero temperatures, and high surface wear resistance.

The Wood Component
Made of oak, the wood component provides excellent flexural and load bearing characteristics well known to the railroad industry. The wood beam is cut to dimension, treated, and dried to pre-determined moisture content before it is ready to be used in production. The treatment utilizes disodium octaborate tetrahydrate (DOT) in accordance with AWPA standards. DOT is environment friendly and will not wash out of the wood as the wood is encapsulated by the plastic component.
Three of the composite railroad ties surfaces are stamped with a pattern to increase the in-track lateral stability of the rail tie.
Additional properties and characteristics are shown here.

Process Characteristics
Incoming materials are subjected to a detailed receiving inspection process. Once approved, the plastic mixture is fed into the patented equipment for processing and delivered into molds where the wood beam is suspended, ready to become a composite railroad tie.
At the end of the cooling cycle, the rail tie is removed from the mold, and is subjected to additional inspection, measurement and testing, to verify compliance with quality specifications.
The rail tie pattern is then imprinted and the composite railroad ties are banded into bundles of 20, ready for shipment to the customer.
One of the biggest drawbacks to using wood railroad ties is the frequent use of creosote as a preservative in wood railroad ties. Coal Tar Creosote is a commonly used wood preservative found in many wooden applications such as telephone poles, rail ties, and switch ties.
While creosote is useful as a wood preservative, it is an extremely toxic substance. The health effects of creosote range from irritation of the skin to more serious issues related to the liver or kidneys, and in some cases even death. Research done by the International Agency for Research on Cancer has concluded that creosote is possibly a human carcinogen.
Given the hazards of wood treated with preservatives such as creosote, many rail companies have begun replacing their wood railroad ties with composite railroad ties made without creosote.

The frequent use of wood in sleeper ties means that the majority of rail ties currently in use are susceptible to insect attack, specifically termite damage. With millions of wood sleeper ties in use throughout the world, many railroad companies end up spending thousands of dollars each year replacing sleeper ties that have fallen prey to termite damage.
Whether through weather, chemicals, or termite damage, thousands of sleeper ties are replaced each year, costing railroad companies thousands in additional track maintenance expenses. While most railroad companies simply use wood sleeper ties to replace the previously damaged ties, more companies are beginning to use composite sleeper ties, which are resistant to a number of environmental factors, such as termite damage.

With many different industrial applications, railroad ties face a variety of factors that can quickly deteriorate a wood railroad tie. Some of these are naturally occurring environmental hazards, such as water damage or termite damage, while others come from the specific purpose of a particular rail line.
Many wood railroad ties used in industrial railways can quickly deteriorate due to the chemicals used in manufacturing or processing or that are hauled on the rail lines. These chemicals include petrochemicals, fly ash, sodium carbonate (soda ash), sodium percarbonate, hydrogen peroxide, sodium hydroxide, caustic soda, and sodium sulfate.
Due to the high costs of maintaining industrial railways, many companies are beginning to replace their old wood railroad ties with more modern composite rail ties.
