Fully adjustable, dual 42-in (1066.8-mm) long augers efficiently metered the LMC in front of the paver's patented Rota-Vibe system. The two 11.5-in (292-mm) long rollers delivered up to 5,000 VPM (83.3 Hz) to reconsolidate the top layer of concrete. This helped to deliver a denser, more uniformly consolidated concrete surface.
"One of the things I like about the 3600 is its flexibility. I can add options in the field to retrofit the paver to meet the needs at the jobsite," comments Solar. Swank Construction's crew used the optional Bid-Well fogging system on the overlay project. The system's unique nozzles atomize water to create a true light fog at a flow rate of 1 to 4 gallons per hour (3.8 to 15.1 lph), which was perfect for a LMC that needs moisture to cure properly.
Even with the tight time frame, Swank Construction was able to finish the project on schedule. "It was a continual process," recalls Solar. "We had close to 100 people working on the bridge over the weekend to mill, hydrodemolish, vacuum, power wash and pave."
The biggest benefit of all, however, is the fact that a LMC overlay is not just a quick fix. The surface wears like iron and should last from 25 to 35 years.
