Roadtec MTV-1100e designed with low profile for better visibility

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 announces Tier 4 Final double drum vibratory asphalt rollers

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.

Going for the ultimate Asphalt Recycling Plant

Asphalt mix produced from 99 percent recycled materials

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.

New Radio Wave Technology Assesses Asphalt Integrity

Properly compacted asphalt is a major factor in the lifespan of roads since inadequately compacted asphalt deteriorates at a more rapid rate than properly compacted material.  
Construction engineers typically assess asphalt by measuring density variations, which can be used to calculate the air void content. The air void content within asphalt varies based on the amount of compaction during asphalt emplacement and variations in the asphalt mix composition. Asphalt with too many air voids (often considered to be more than 8 percent) deteriorates at a more rapid rate. Too few air voids (less than 3 percent) results from over-compacted asphalt, which is also undesirable. In either case, the asphalt is subject to early failure and the road’s lifetime is less than asphalt that contains the optimal air void content.

Sandvik introduces tool for abrasive asphalt milling conditions

Sandvik Mining and Rock Technology introduces its new Double TriSpec tool, which is intended for use in extremely abrasive asphalt milling conditions. In road milling, the greatest cause of tool failure is known as body wash – the premature wearing away of the steel body that surrounds and supports the vital brazed-carbide insert in each of the tools on the milling drum. When body wash occurs, the tool’s steel body becomes vulnerable to failure, and the tool must be changed long before the carbide tip has been fully utilized – resulting in downtime, lost production and higher labor costs.

Pneumatic tire roller adaptable for uniform smoothness and performance

Volvo Construction Equipment’s PT125C nine-wheeled pneumatic tire roller is an exceptionally adaptable machine that delivers uniform smoothness and long-lasting performance. Designed for roadway construction and resurfacing applications, the machine employs a kneading action for the compaction of hot and warm mix asphalt. The PT125C is also appropriate for chip seal applications, thanks to its heavy-duty 14-ply tires, which press the aggregate into the binder without fracturing.
