RIDOT Tests PPEST

Rhode Island steps up their preservation game with paver placed surface treatments.

As opposed to some surface treatment options that require special equipment, microsurfacing for example, PPEST can be installed using conventional paving equipment that you use to place hot mix asphalt; a hauling truck, a hot mix paver and a steel drum roller.

How E-Construction Can Increase Your Efficiency and Your Bottom Line

The Iowa DOT and Manatts Construction partnered with Earthwave Technologies on a pilot project to reduce time-consuming paper shuffling

The pilot project involved an 8-mile resurfacing job on Highway 69 in Central Iowa. The first phase of the pilot was completed without telematics. The second phase used Earthwave Fleetwatcher to monitor HMA delivery trucks and two pavers used on the job.

Contractor Crushes the Bottom Line with New Recycling Equipment

Ajax Paving Industries invests in a mobile crushing and screening spread and cuts costs, produces a higher quality product, increases the amount of recycle in the mix and eliminates subcontractors.

Any overs from the crushing process are fed from the middle-deck screen back to the impactor, where it is crushed again to make a finished product. This product is then conveyed and stockpiled to be added to the asphalt plant.

Interstate Rehab Project Earns Contractor Bonus and Award

Peavy and Son Construction had 120 days to complete a full-depth milling and paving on Florida's highly travelled I-10 between Tallahassee and Monticello

In 2015, FDOT awarded the complete rehab of an eight-mile section of I-10 falling between Tallahassee and Monticello, FL, to Peavy and Son Construction Co.

Asphalt Emulsions Provide Cohesion, Improve Aged Binder

Full-depth reclamation with asphalt emulsions creates an ideal treatment for thin bituminous pavements needing upgrading or rehab

In Monroe County, MI, full depth reclamation, engineered asphalt emulsion is injected into reclaimed materials as they are mixed.

Paving Non-Parking Lot Award Winner: Porous Pavement Poses Challenges for Finley Asphalt

Construction of a multi-use recreational court for the Congressional School of Virginia tested the talents of the Finley team.

“The paving of tennis courts, sports courts, and running tracks is what we call the plastic surgery of paving,” says Eric Finley, owner of Finley Asphalt. “The smoothness tolerance is typically ¼” when checked with a 10’ straight edge, and of course no standing water. The goal is to have the asphalt surface as flat as possible with just enough slope to drain the water off. Typically most parking lots are designed with 1.5% to 2% slope. Sports surfaces range from .83% to 1%.”

Why Pavement Maintenance Contractors Need a Skid Steer

With an ever growing array of available attachments, the role of a skid steer on a jobsite is bigger than ever.

Buckets are essential attachments for any stage of work. Their versatility can handle everything from site prep, to supplying the paver to debris handling.
