• Precast concrete transportation products are used in the construction, safety and site protection of our road, airport and railroad transportation systems. Products include: box culverts, 3-sided culverts, bridge systems, railroad crossings, railroad ties, short-span bridges, sound walls/barriers, traffic barriers, tunnel segments and other transportation products.

BOX CULVERTS

Precast concrete box culverts are used for conveyance of fluids such as stormwater and sewage as well as for short span-bridges and access ways. Precast concrete three-sided culverts allow for natural streambeds to remain intact while providing for short-span bridge applications. Because precast box culverts are produced in a controlled environment, they will exhibit high degrees of quality and uniformity. They also offer a multitude of advantages such as superior strength and durability, reduced weather dependency for installation, design flexibility and reduced impact to the job site. Precast concrete is also an environmentally friendly material that will always be readily available. Box culverts are common products and many manufacturers maintain an inventory of several sizes of box culverts ready to be delivered in short notice.

PAVING SLABS

Precast concrete pavement slabs (PCPS) are prefabricated offsite in factory-controlled conditions that are delivered to the job site fully cured and ready to be installed for immediate use. The precast slabs are typically placed upon a prepared subgrade surface that fully supports and positions them such that the top surface of the slab meets the required theoretical pavement surface within specified tolerances.

Precast concrete pavement systems are installed rapidly in abbreviated work windows, some as short as 5 hours, on heavily congested traffic corridors and will result in concrete pavement that will withstand heavy traffic flow over many years.

SHORT-SPAN BRIDGES

Whether you want to replace an aging, deficient bridge, span a creek or river for a golf course cart path, expand an airport tarmac over a roadway, develop a tunnel for vehicular traffic, or provide access to land for new development, a precast concrete short-span bridge is the solution.

Designs include attractive single-piece arches, functional two-piece arches, conventionally reinforced flat bridges, parapets, wingwalls, headwalls and endwalls. Each system has its own specification for span length, span height and load capacity.

SOUND WALLS

Noise problem? We’ve got the solution — precast concrete sound walls!

With growing traffic and expanding communities, road noise has become a real irritant for communities living along the nation’s highways.

Precast concrete sound walls can be designed to blend in with a city’s architecture and local topography, or even to capture a community’s theme or identity. Reflective sound walls can reduce the perceived noise by as much as half, while absorptive treatments have been found to further reduce noise pollution. And with color additives or stains and textured form liners, the options are nearly endless.

TRAFFIC BARRIERS

Precast concrete highway barriers serve as more than just barricades against unwanted vehicular traffic — they also serve as safety and security devices. When installed parallel to roadways, precast concrete barriers have the unique ability to not only realign stray vehicles, but also reduce their speed. Upon impact, precast concrete barriers partially lift the stray vehicle off the pavement, which decreases the lateral resistance force between tires and pavement. Once this force is minimized, the barriers can effectively realign and slow the stray vehicle. Precast barriers can be installed in permanent or temporary applications.
