Warm mix project yields valuable research

Long haul posed little challenge for warm mix placement on Nebraska warm mix highway project for Knife River's Midwest Division.

The project consisted of 6,000 tons of conventional hot mix and 5,570 tons of warm mix. The temperature of the mix was monitored to determine the rolling pattern required to achieve density for both hot and warm mixes.

New plant addresses market growth, mega project

To minimize disruption to production demand, Florida asphalt producer/contractor installs new plant in 19 days.

New components of the plant included three Meeker 30,000-gallon AC tanks.

Nevada Pequop I-80 CIR

Nevada?s second Interstate 80 cold in-place recycling (CIR) east of Elko exhibits the road agency?s confidence in using the rehabilitation approach on a heavily-traveled corridor.

After completing the inside lanes of the two project sections, Valentine's CIR crew began work on the 12-foot outside travel lanes and the 10-foot outside shoulders.

Shingles - a valuable paving resource

Minnesota asphalt producer/contractor continues to pave the way by recycling waste roofing shingles into high-performance paving projects, like the recently completed Trunk Highway 149 in Eagan, MN.

Editor's Perspective

'Tank' delivers high production

Stavola Companies of New Jersey adds a heavy-duty Dillman 600-tph asphalt plant to its Bound Brook location to meet high-production needs.

With the two plants, the Bound Brook facility will produce 750,000 tons of mix annually to support Stavola paving crews and outside customers.

Juggling an interstate resurfacing project

Waukesha, WI-based asphalt producer/contractor Payne & Dolan delivers a smooth ride, while maintaining open travel lanes on a busy section of I-94 west of Milwaukee.

To accomplish the resurfacing work required for the Interstate 94 project, Payne & Dolan milled and paved at the same time during the night when one of the travel lanes could be closed.
