New Paving Equipment Helps Your Bottom Line
You might think after all the new offerings at World of Asphalt 2019 back in February meant original equipment manufacturers (OEMs) would sit back and relax for a while. That’s not the case. More goodies were launched at BAUMA 2019 in Munich and additional updates have hit the marketplace independent of specific tradeshows. For example, Grote Industries Inc., Madison, Indiana, has continued to release light emitting diode (LED) hazard lights for the construction and other industries in answer to power consumption concerns when it comes to the need to increase brightness. Here’s the article Grote prepared, which leads us into this month’s look at paving and pavement maintenance equipment offerings.
Upgrade LED Hazard, Warning Strobe Lights
To ensure the visibility and safety of everyone on the road, the Society of Automotive Engineers (SAE) mandates that vehicles such as construction, utility, tow and snowplow trucks are equipped with hazard and warning lights. Whether roof-mounted beacons or directional surface mounted to the vehicle’s body or grill, these flashing strobe lights are to capture the attention of motorists and pedestrians and warn of a potentially hazardous activity or situation.
They’re available in several colors—amber, white and blue—and a variety of pulsating strobe effects. They come in several SAE classes and mounting styles depending on how quickly the vehicle will be moving. As the lighting world continues to transition to LEDs, these hazard and warning lights are now available in low electrical consumption, long life models that exceed traditional halogen or gas-discharge options. Making this move attractive for fleet managers are the plummeting prices of LED technology, which have decreased to the point that many vehicles that require Class 2 lights are instead being outfitted with brighter, Class 1 options given the minimal price differential.
“Today, the entire hazard and warning light industry is undergoing a significant sea change—namely, the industry’s shift to LED technology,” Chris Cammack of Grote Industries said.
“The reason for this migration comes down to three factors: energy efficiency, longer service life and brightness. LEDs consume less power than any other lighting technology on the market and are powered by low voltage, allowing for minimal draw of electrical current from the vehicle’s battery.”
LEDs consume about 25-35 percent of the power of gas-discharge strobe and halogen lights. As a result, LED strobe lights have a service life that is 10 times longer, often lasting 70,000 hours or more, according to the company.
LED quality has continued to improve as well. In the early days of LEDs, they were not bright enough to meet SAE requirements for luminous intensity of hazard and warning lights, measured in candelas. However, technology has advanced and LEDs are now as bright—if not brighter—than the average strobe or halogen light.
“LEDs today are much brighter,” Cammack said. “Today, they are more than bright enough to meet the SAE standard for candela over 100 feet.”
For manufacturers such as Grote, the options are virtually unlimited.

Of the more than 100 products Ammann Group, Langenthal, Switzerland, had on display at Bauma in April, a new line of soil compactors featured new technological solutions to meet the latest emissions standards, reduce fuel use, and provide data to eliminate unnecessary passes on jobsites. A variable range of frequencies and centrifugal forces provide the required compaction ability and make the machines productive in many applications and on varied materials and compaction thicknesses, according to the manufacturer.
Sustainability efforts center on the new ECOdrop initiative that is being used across the Ammann product line. Among the benefits of ECOdrop are improved machine serviceability and engine efficiency that leads to lower fuel costs. Hydraulic and vibratory components have been optimized to reduce the fluids required to run the system.
“The savings with ECOdrop are substantial,” Vlasta Medek, Global Commercial Compaction, said. “For example, with the ARS 70, fuel consumption dropped 22 percent. The required hydraulic oil dropped by 26 percent and the oil needed in the vibratory system was reduced by 10 percent. Customers therefore can expect a corresponding drop in the costs of fluid acquisition and disposal.”
Standard on the ARS 70 is the Kubota V3307-CR-TE4 diesel engine. The Deutz TCD3.6L4 engine is standard on the ARS 110 and ARS 130; the Deutz TCD4.1L4 is standard on the ARS 150 and ARS 170. The rollers are compact because of the innovative no-rear-axle concept, which positions the engine, coolers, liquid tanks and hydraulic components in the engine compartment. All these new design innovations enable a unique range of new technical advantages—maneuverability chief among them—according to the manufacturer.
Ammann also commemorated its 150th anniversary at Bauma.

One of HAMM’s highlights at World of Asphalt 2019 was its tandem roller DV+ 90i VV-S, a model from Series DV+. These pivot-steered tandem rollers are available in two weight categories (7.7 tons and 9.9 tons). All of the eight models come with split vibration drums as a standard feature. Brand new on the market are the new models offered by Hamm with a split oscillation drum. They combine the benefits of oscillation with the added value of a split drum.
The pivot-steered rollers of the DV+ series are available as tandem roller with double vibration, as tandem roller with one vibration and one oscillation drum, or as combi roller. They feature intelligent drive control plus pivot steering with four steering modes and large turning angles.
New in the DV+ series are models with split oscillation drum: DV+ 70i VS-OS and DV+ 90i VS-OS. They combine the benefits of oscillation with the added value of a split drum.
Developed and patented by Hamm, this premium solution is the only one of its kind on the market. A separate, mechanically-independent oscillation unit operates in each half of the split oscillation drums. An integrated control mechanism adjusts the rotational speeds of each half of the drum to match one another. The synchronization is done electro-hydraulically. Because the system reacts quickly and precisely, synchronous vibration in each of the two drum halves is guaranteed in any situation, according to the manufacturer.
This reduces the danger of cracks in or displacement of the asphalt.
Refueling breaks interrupt the compaction process. To avoid them, Hamm has equipped the DV+ series tandem rollers with large water and fuel tanks. Filling is user-friendly because the water can be replenished centrally from the ground via a pressurized supply of at least 14.7 psi (1 bar) as a standard feature. Because the tanks are linked together via communicating pipework, they are filled simultaneously. Connection to a hydrant is also an option. Alternatively, water can be gravity-fed from above in the traditional way via one of the four filling spouts on the top. Replenishment of diesel and hydraulic fluid is also conveniently arranged: both can be carried out from ground level.
Despite the extensive machine functions, operation of the DV+ has been made intuitive. The key to this is the innovative Easy Drive operating concept, developed by Hamm in collaboration with universities and experts in ergonomics, as well as roller drivers from different countries. At the heart of the operating concept is an ergonomically optimized operator platform with many details. For example, the seat allows the driver to adopt a relaxed sitting position, facing in the direction of travel in all situations, as it can be turned mechanically by 90 degrees in either direction, and shifted to the left or right as standard. Another key feature of Easy Drive is its operating structure. A steering wheel is used for steering. All other important functions are operated via a joystick and the multifunction armrest. Here, the driver is able to see all the keys on the joystick. All other operating elements are arranged around the joystick in such a way that the most frequently used ones are placed closest to it. At the same time, the operation is designed to be entirely language-neutral. Hamm uses color coding to achieve unambiguous assignment of the functions, and a clear overview.
All DV+ series models are equipped with state-of-the-art engines, satisfying requirements of EPA Tier 4 emissions requirements. So the rollers are equipped with future-proof technology that can be used even in the most strictly regulated markets. An automatic engine stop system can also be incorporated as an optional extra; it switches the engine off during extended periods of inactivity, saving fuel.

EU Stage V-certified, air- and liquid-cooled engines that comply with the directive that’s been in force since Jan. 1, 2019, are now available for machine manufacturers and Hatz partners. Hatz has received official certification for its EU Stage V-compliant engines for mobile machines from the German Federal Motor Transport Authority (KBA). The certification applies to air-cooled engines of the B-, D-, G-, L- and M-series with a power output of less than 19 kilowatts. Since 2013, these engines have fulfilled the EPA Tier 4 final emission stage and have now also been certified in accordance with EU Stage V regulations—without any technical modifications or additional exhaust gas aftertreatment.
The KBA has also granted type approvals for the new Hatz H-series liquid-cooled engines that were specially developed for EU Stage V using innovative technology. The 3H50TICD and 4H50TICD three-cylinder and four-cylinder engines in power classes from 19 to 55 kilowatts are now available with an official EU Stage V certificate.
To meet the requirements of EU Stage V, the three-cylinder and four-cylinder engines are also equipped with a separable combination of diesel oxidation catalytic converter and diesel particulate filter (DOC/DPF). With optiHEAT (optimised Hatz Exhaust Aftertreatment Technology), the Hatz engineers ensured their best design of the DPF in terms of size, optimum adaptation to the possible load profiles in use and a regeneration strategy in line with requirements. In addition, combustion is perfected with iHACS (intelligent Hatz Advanced Combustion Strategy). iHACS ensures low soot input from combustion as well as low oil consumption and reduced ash input into the filter. The result is a long filter service life with a comparatively small size. Hatz achieved another industry-wide innovation with diesel article filter regeneration. For the first time, an automatic cylinder deactivation during standstill regeneration was integrated in industrial diesel engines.

Process Heating Company
The Patch King pothole patcher from Process Heating Company (PHCo), Seattle, heats hot or cold mix patching material and keeps it at the desired working temperature, from 50° to 350° F, for at least 10 hours, according to the manufacturer. The unit features Lo-Density® open-coil, drywell-style heaters, evenly distributed across the sides, bottom, ends and discharge doors, which dissipate up to 1 watt per square inch of heat. Operators can either heat the material at the beginning of the day, set a time clock for early morning pre-heating or keep it hot overnight for more efficient use of material and improved worker productivity. It heats without flame.
Available in insulated 3.0-, 4.0- or 8.0-cubic yard models, the Patch King is popular with municipalities and road maintenance contractors because the insulated patch box easily mounts into a dump truck or onto a flatbed to keep mix hot all shift. UL-listed controls located on the unit offer easy-to-use, complete automation of temperature regulation. A high-low heat selector switch mounted in the control panel can supply heat individually to the floor and gates—or to the floor, sides, ends, and gates, providing heat for full or partial loads.
The main disconnect and individually fused heat circuits provide overcurrent protection. All components are mounted and prewired in a UL-listed, weatherproof enclosure.
In addition to the standard dump model, the Patch King is available in a trailer model and a rotary auger model. On the rotary auger model, the reversible rotary conveyor is driven by a hydraulic motor and supported by heavy-duty ball bearings. A mix/anti-bridging device features separate hydraulic drive and controls. The wear parts, including auger, are easily replaceable. The reversible auger feeds patch mix to the work area to eliminate costly dump beds and hoists. All other features are the same as the standard model. The drywell-style elements are accessible from outside of the body for service ease.

Topcon Positioning Group
Topcon Positioning Group, Livermore, California, introduces Pavelink, a cloud-based logistics application designed to connect stakeholders in real-time throughout the paving process. The mobile application is designed to complete a connected ecosystem workflow between the asphalt plant, delivery trucks, company office and paving site. The software as a service (SaaS) application has been developed by the Topcon Technology Eindhoven paving application center in the Netherlands, which expands the portfolio of Topcon paving solutions. It is designed to integrate with existing planning and management tools.
“Pavelink is a revolutionary way to plan and manage the asphalt paving process with real-time visibility throughout the project lifecycle,” said Murray Lodge, senior VP, construction.
“The system automatically gathers and centralizes all relevant information such as quantities, temperatures, number of trucks loaded, current truck locations, job site arrival estimations, number of trucks returning or queuing for more loads, current screed width, current paver speed, and amount of roadway that has been laid.
“The information provides real-time visibility for every stakeholder. The entire team can be reached in an instant with smooth communication. If the mix needs to be adjusted, for example, the field crew can easily signal the asphalt plant. They can also ask to expedite material and send more or fewer loads. The home office has access to the real-time data, facilitating assistance with daily job management,” he said.
The system automatically generates digital weigh tickets at the plant that are delivered to the truck driver’s loaded app, as well as uses geofence recognition of the arrival of a haul truck at the job site, and tracks all activity digitally. Lodge said, “This logistics application is the newest piece of the Topcon end-to-end paving solution offering.”

SprayJet technology from Vögele, a Wirtgen Group company, Antioch, Tennessee, is used for pavement rehabilitation and construction in many markets around the world. The operation of the SUPER 1800-3i SprayJet spray module has been integrated into the ErgoPlus 3 operating concept. The module is designed as a completely self-contained functional unit. This modular design makes the new SUPER 1800-3i SprayJet simple to service and allows it to be used both as a spray paver and as a conventional asphalt paver. The paver has a maximum spray width of up to 19.6 feet. As a conventional paver without spray function it can pave widths of up to 29.5 feet.
The insulated emulsion tank has a capacity of 555 gallons. (The capacity can be increased to 1,875 gallons with an optional additional emulsion tank.) The integrated electric heating ensures that the emulsion is maintained at the ideal temperature for spraying. A heated emulsion pump circulates the bitumen emulsion in the tank, keeping it homogenized. An additional filler port on the left-hand side of the Dash 3 spray module makes for greater flexibility when refilling. All the main service points are readily accessible behind large service panels, even with the spray module installed.
The SUPER 1800-3i SprayJet is equipped with five spray bars. The front spray bar has six spray nozzles and is located between the machine’s crawler tracks right behind the push-rollers. An articulated spray bar installed on each side of the paver comes with seven nozzles per side. Finally, a short spray bar with two nozzles is provided right behind each crawler track. This arrangement of the spray bars allows full coverage of the existing surface with emulsion, even when the paving width varies. The rate of spread can be selected accurately.
The SprayJet nozzles do not spray the emulsion continuously, but operate instead in pulsed mode. The frequency of the spray pulses is adjusted automatically as a function of the selected rate of spread, paving speed and paving width.
For the SUPER 1800-3i SprayJet, two screed options are available: AB 500 and AB 600. Either of the extending screeds handles pave widths up to 19.6 feet. AB 600 comes with a basic width of 10 feet and extends hydraulically up to 19.6 feet. AB 500 builds up to its maximum width of 19.6 feet with additional bolt-on extensions of 2.5 feet. The widths of the screeds are limited electronically to a maximum of 19.6 feet. As a conventional paver without spray function it can pave widths of up to 29.5 feet with the AB 600. Either screed is available in TV version (with tamper and vibrators) or in TP1 version (with tamper and one pressure bar). Like all Vögele screeds, the AB 500 and AB 600 Extending Screeds also feature electric heating.
