Highway repair material

Long Life Highway Repair is an asphalt cold mix formulated to outlast standard cold mixes and hot-mix patching materials in cold, wet conditions under highway traffic. The product is viscosity graded to be workable in cold temperatures, making it possible for road crews to install quickly. Cutting Edge Cold Mixes. www.meredithbrothersinc.com.

Recycled asphalt

Green Mix recycled asphalt can help a roadway or parking area project attain LEED certification, or it may bump a certified structure into a LEED Silver, Gold, or Platinum premium certification. Made from recycled asphalt pavement, the product can be placed, graded, and compacted. It accommodates heavy traffic almost immediately. It typically serves as a durable base to support a thin asphalt wearing course or surface treatment. Wirtgen America Inc. www.wirtgenamerica.com.

Flatwork screed

The WRS SuperScreed is ideal for flatwork and paving applications. It's sectional truss frame and several strike tube lengths allow it to strike off 14-to 52-ft. panels. It works on highway offramps and on curved and tapered roadways. Powered by a removable hydraulic power unit that's driven by either a 20-hp gasoline or 28-hp diesel engine, the self-propelled roller screed requires one operator, two laborers, and two concrete placers. Multiquip Inc. www.multiquip.com.

Vibratory rollers

The 200 Series of vibratory compaction rollers can be used in a variety of asphalt paving applications. With engine ranges from 27 to 148 hp, the rollers offer high centrifugal forces, 360-degree visibility, rugged components, and up to 36 hours of operation per fuel fill. Case Construction Equipment. www.casece.com.


Pothole patcher

With its insulated electric-heated hopper and thermostat, the FP5 Flameless Pothole Patcher reduces material waste while keeping asphalt pliant and at a constant temperature. The damaged area is first removed and squared off with the pavement breaker. Then the air and tack wand blows out any remaining debris and applies the tack coating. The material chute delivers fresh, hot asphalt and consolidates the material evenly with existing pavement. Bergkamp Inc. www.bergkampinc.com.

Spray patcher

One person can control all patching functions from inside the cab with the RA-300 spray patcher. This spray-injection system allows patching on the go with no need for auxiliary power. The operator uses joystick control to extend and retract the patching boom. The three-stage telescoping aggregate delivery tube and emulsion hose take-up reel provide a wide patching range with minimal maintenance. Patching can be done in less than a minute. Rosco, a LeeBoy Co. www.leeboy.com.

Tack coat applicator

The trailer-mounted Tack Kettle heats and applies bituminous emulsions and tack coats. Its staggered dual flue design offers even, energy-efficient heating. Other features include a large solvent/flush tank and 36332-in. maintenance hatch for speedy cleanup, and a 50-ft. retractable material hose with lightweight spray wand. Two models are available: 500-gal. and 250-gal. Cimline Inc. www.cimline.com.

Structural geogrid system

The Spectra roadway improvement system combines Tensar Biaxial (BX) and Uniaxial (UX) geogrids with crushed aggregate and/or granular fill to improve subgrade and base course performance. It's used beneath roadways, parking lots, and more to allow heavy construction on sites with weak soils, eliminating all or most foundation and/or soil stabilization work. Geogrids are made from either polyethylene, to resist elongation; or from polypropylene or copolymers, to resist high, short-term dynamic loads and moderate loads over longer time periods.
