The Roadtec CIR Additive System is used in the cold-in-place recycling of asphalt pavement in the repair and rehabilitation of asphalt-paved roads. The system is used to transfer, measure, and inject either emulsion or foamed asphalt to the cutter housing of the milling machine. The additive is then thoroughly blended with the milled material and transferred for paving.
Asphalt Drum Mixers, Inc. offers the EX120 asphalt plant as a solution for producers who need a portable counterflow plant that can process high percentages of RAP. Featuring single-drum counterflow technology, the compact 120-tph EX Series plant meets all federal and state emission regulations.
The new M310CS truck-mounted slurry seal and micro surfacing paver from Bergkamp Inc. receives power from the Tier 4 truck engine that fulfills stringent emissions regulations. Based on customer feedback, Bergkamp developed the M310CS with the same proven design, efficiency and productivity as its M310 paver, but with PTO-driven hydraulic pumps that allow elimination of the side engine. This feature, along with the Tier 4 truck engine technology, allows customers to reduce their emissions reporting and equipment maintenance needs.
Costello Industries, Inc., a milling service provider based in Newington, CT, relies exclusively on cold milling from Wirtgen. Costello Industries has been rehabilitating highways, streets and bridges since 1945. "The focus of our work is on safety, quality and productivity," says Todd Nedzweckas, Operations Manager at Costello. "We specialize in milling work and offer additional services, such as road, highway and bridge repair and maintenance."
The new Case DV23CC and DV26CC combination vibratory rollers compact with the front drum and deliver a smooth finish with rear pneumatic tires. An inline drum with tapered edge and high curb clearance offers precision compaction capabilities in tight spaces, and adjustable scrapers, an automatic vibration control system and a pressurized water system ensure a smooth, clean finish in a variety of asphalt applications.
BOMAG, the specialist in road construction and asphalt and soil compaction, is celebrating its 60th anniversary this year. The company's focus on innovation, quality, user-friendly products and the highest level of service has transformed a small business into a successful global manufacturer of construction machinery. BOMAG - founded in the town center of Boppard/Rhine in Germany in October 1957 - now employs approximately 2,200 employees and generates annual revenue of about € 700 million. The company has production plants in Germany, Italy, Brazil, the United States and China.
Purchasing an asphalt plant is a serious decision for any company, small or large, as prices range from $500,000 to $4 million. However, there may be good reasons to consider the purchase. If you buy asphalt from a supplier, your truck drivers may have to wait in line to receive hot mix. Then they have to make the trip back to the worksite, which could be many kilometres away. Finally, the crew may be doing some waiting of its own; after all, work can’t progress without the hot mix, so the crew is stalled until the truck arrives. There is also the actual cost of the asphalt, something the receiving companies have no control over.
CASE Construction Equipment now offers two new combination vibratory rollers - the DV209CD and DV210CD. The new vibratory rollers compact with the front drum and deliver a smooth finish with rear pneumatic tires. The DV209CD and DV210CD come standard with automatic vibration control, crab steering, an oscillating articulated roller joint and a pressurized triple-filtration water system. High-frequency is offered as a standard feature allowing for frequencies up to 4,020 vpm (67 Hz) for greater control of compaction performance based on the thickness and density requirements of each lift.
Time is money, especially in road construction. When it comes to cost efficiency, being able to put all equipment to maximum use is a critical factor. Consequently, it is a major advantage when a machine can be used flexibly, like the 3800 CR recycler from Wirtgen, which can use the up-cut and down-cut cold recycling processes or operate as a high-output milling machine. Thanks to its diverse application options, the recycler fulfills unique construction specifications as required by an application or invitation to tender.
Caterpillar’s PM620 and PM622 Cold Planers are half-lane milling machines that perform controlled full-depth removal of asphalt and concrete pavements in a single pass. They are powered by a Cat C18 ACERT engine, a turbocharged, 6-cylinder diesel engine that provides 470 kW (630 hp) of gross power, meets Tier 4 Final emission standards and is iso-mounted to reduce vibration and increase operator comfort. Turbocharged air-to-air aftercooling provides high horsepower with increased response time, while Automatic Engine Speed Control optimizes output to match the load, reducing excessive fuel consumption and wear on the engine. Approximate weights for the PM620 and PM622, respectively, are: operating weight of 33,330 kg and 33,900 kg; transport weight of 29,400 kg and 30,000 kg.
Zhengzhou Yutong Heavy Industries Co., Ltd. has become the first Chinese manufacturer to participate in the Trimble Ready program for dynamic compaction applications. As part of the program, Trimble and Yutong will work together to integrate the Trimble DPS900 Machine Control System onto Yutong dynamic compaction machines.
The new Sakai SW754, 67-inch vibratory tandem drum roller offers improved operating efficiency as well as ease-of-maintenance while retaining many of features of its successful 770-series line. Applications include both thin and thick asphalt lift compaction, as well as compaction of coarse graded asphalt mixes and aggregate base and subbase layers. EPA Tier 4 emissions compliance is achieved by an efficient 3.8 L Kubota engine offering up to 10 hours of actual run time without refueling.
Wacker Neuson has expanded its compaction equipment product offering with a line of tandem and combination rollers. The comprehensive line offers 15 models with operating weights ranging from 1.8 to 4.5 tons. Designed to increase productivity, while offering operator comfort and convenience, these rollers feature maneuverability, safety, optional configurations and Tier 4 Final engines. The RD series of ride-on rollers deliver quality results in demanding conditions.
The Roadtec MTV-1100e offers a low, machine-height profile, which is designed to keep the operator closer to the ground. The lower 9’ 10½” (3m) machine height with a deck height of 6’ 2” (2m) is designed to provide the machine operator with a clearer view of the surroundings and the ability to more easily talk with ground crew. A dual staircase with handrails flanks the machine allowing workers to cross the paving train without risk of being on the ground between machines.
CASE Construction Equipment has introduced two new double drum asphalt rollers—the DV209D and DV210D. The new vibratory asphalt rollers deliver 100 percent tractive effort and reliable compaction performance due to a balanced drum design and a variety of standard features, including automatic vibration control, crab steering, an oscillating articulated roller joint and a pressurized triple-filtration water system. An available high-frequency option allows for frequencies up to 4,020 vpm (67 Hz) for greater control of compaction performance based on the thickness and density requirements of each lift. A combination option is also available for both models, featuring a vibratory front roller and rear pneumatic tires that provide a smooth surface finish.
The new BOMAG BM 2200/75 delivers high-performance milling of half-lane widths reaching 86.6 in (2,200 mm) at precise milling depths of up to 13.8 in (350 mm). Offering range of quick-change milling drums options and efficient transition of engine to milling power, this largest cold mill in the BOMAG product line is ideally suited for high performance applications such as major roads, highways, and airports.
CASE Construction Equipment has launched the DV45CC combination vibratory roller. The new vibratory roller compacts with the front drum and delivers a smooth finish with the rear pneumatic tires. An offset drum with tapered edge and high curb clearance offers precision compaction capabilities in tight spaces; and adjustable scrapers, an automatic vibration control system and a pressurized water system ensure a smooth, clean finish in a variety of asphalt applications.
Ammann now has an asphalt mixing plant that not only utilizes recycled asphalt (RAP) but also incorporates consumer waste, such as glass bottles, tires and fly ash. The result is a mix comprised of 99 percent recycled materials – or put another way, a mix that uses only one percent virgin materials.
