Construction communication system

eRoutes.info is a real-time information system that gathers operational data from all aspects of the construction process, so that project managers obtain an overview of everything going on at a jobsite. It gathers information from the production data logger at the plant, at the transport level (truck position relative to the plant and paver), from the paver itself (position, speed, and other data), and from compactors and other moving machines. Minds Inc. www.mindsinc.ca..

Mid-size cold mills

The W 120 F cold-milling machine has a width of 4 feet, features front-end loading of recycled asphalt via a two-part conveyor system, and can be equipped with either wheels or tracks. The machine cuts to 12.6 inches deep. The W 60 cold mill is a 2-foot-wide machine with a flexible rear loader, making it suitable for trench and channel digging; it cuts to 11.8 inches deep. Wirtgen America. www.wirtgenamerica.com..

Flameless pothole patcher

The FP5 has an insulated 5.1-cu.-yd. hopper that uses electric heat to keep asphalt at a constant temperature. The machine removes material from the damaged area and squares it off with a breaker. Then, its air-and-tack wand blows out remaining debris and applies the tack coating, binding the new asphalt to the existing pavement. The material chute delivers the fresh asphalt to the prepared area, and the compactor consolidates it. The process reduces material waste and saves money. Bergkamp Inc. www.bergkampinc.com..

Moisture/density measurement

The Apex 3430+ moisture/density gauge offers direct readout of wet and dry density, moisture, percent moisture, percent voids, and percent compaction on an enlarged four-line, 20-character display. It can store up to 999 readings, and has NiMH batteries that recharge in approximately three hours. The 3440+ model also has a remote-start keypad, USB port, and end-of-count signal.

Cold asphalt repair

EZ Street cold asphalt can be used to fix potholes, utility cuts, edge repairs, and small overlays in any weather conditions. The product is permanent, does not require mixing, avoids the mess associated with hot-mix asphalt, and can be opened to traffic right after application. Little or no machinery is required to apply. The EZ Street Co. www.ezstreet-miami.com..

Ground-tire asphalt

GTR (ground-tire rubber) asphalt contains recycled rubber from used tires—approximately 2000 tires go into resurfacing 1 mile of a typical two-lane road. The product leads to a high-quality surface with reduced road noise, and installation creates up to 15% reduced emissions compared to standard asphalt mixes. The material is highly workable, and little to no modification is required to work with conventional hot-mix equipment. Seneca Petroleum Co.

Rubber repair plates

TempRamps offer a safer temporary pothole repair than steel utility plates or cold patch. The durable, recycled-rubber repair plates are placed and fasten with anchors. When ready to permanently resurface the pavement, simply remove the anchors and store the plates; they can be reused repeatedly for years. EZ Road Inc. www.tempramp.com..

Custom asphalt formulation

The company offers more than 75 different asphalt emulsions for a wide range of jobsite requirements. The materials are suitable for surface treatments, chip sealing, cold-in-place recycling, cold-mix patching and paving, full-depth reclamation, and other applications. McAsphalt Industries Ltd. www.mcasphalt.com..

Asphalt reclaimers

The RC16000D is a self-contained, 8-ton infrared asphalt reclaimer and storage unit. The truck-mounted dumping unit features hydraulic loading and discharge doors. The machine reclaims, holds, and stores either plant-mix or previously used asphalt at working temperatures, for extended intervals. Ray-Tech Infrared Corp. www.raytechinfrared.com..
