Project Spotlight: Retail Grocery

THE CHALLENGE:

Builtech, LLC received 6 inches of rain in 7 days in late October.

With Winter nearing and the asphalt plants shutting down for the year

Builtech had to act fast to dry their site to keep their project delivery date on schedule.

THE SOLUTION:

They needed Soil Stabilization with Portland Cement to guarantee their project stayed on schedule.

Multiple lifts, totaling over 17,000 SYs treated with 445 tons of Portland Cement in 3 short days did the trick.

By drying and strengthening each lift to meet compaction, Builtech was able to place their asphalt by late November, avoiding costly delays.

We want to recognize Builtech, LLC for choosing to build smarter, build faster, & build better.

The Problem:

Alston Construction and Witech Excavating needed to expedite Project Heartland to guarantee their building pad would be completed before winter. Wet fill and cooler temperatures put their project schedule at risk.

The Solution:

Using Soil modification with quick lime, dried the wet fill to meet compaction requirements.

Capping the building pad with cement stabilization, protects it from Old Man Winter.

In 19 days over 520,000 SYs of wet fill were treated with quick lime (that’s over 27,000 SY’s per day)

In 6 short days the building pad was cement stabilized to beat the schedule (that’s 25,000 SY’s per day)

We want to recognize Alston Construction and Witech Company for choosing to build smarter, build faster, & build better.

Andy Hynes, Deputy City Engineer on the Brush Hill Project was just one of the many employees within the engineering department at the City of Naperville. Andy has helped advance the use of Full Depth Reclamation on Naperville streets over the past 4 years to help repair their cities failing asphalt roads.

The city of Naperville started using FDR in 2015 when they came across an emergency that needed to be fixed right away. Once they removed the existing asphalt pavement in a cul-de-sac, they saw the aggregate base needed some extensive repairs. Their time was limited so they knew doing a full reconstruction was not an option. After talking with their peers and the contractor they decided to try Full Depth Reclamation. Now, 4 years later they are using this process to reclaim a number of neighborhood and city streets throughout Naperville.

One of the three Full Depth Reclamation projects they performed in 2019 was the Brush Hill Project. This project covered just under a mile of neighborhood roads, equating to ~14,000 SY’s. By implementing FDR with Cement, The City of Naperville not only cuts their costs in half as compared to full depth removal and replacement but cuts their construction timeline even more. In summary, they are getting a stronger road, at half the cost, in less than half the time.

The city of Naperville, since 2015, has completed ~378,000 square yards of FDR (~59,000 square yards of that coming in 2019) and recycled over 245,000 tons of aggregate base.

“The process has, overall, been beneficial. Less impact on the residence, as they are not out of their driveways for a couple weeks at a time (as compared to full reconstruction). On top of that you also have cost savings, so there are a lot of advantages to FDR.” – Andy Hynes, City of Naperville.

Check out this quick video of Rock Solid Stabilization direct injecting 1.7 gallons of asphalt emulsion per SY with one of our Wirtgen WR 250i Reclaimers.  The 3.2 mile Full Depth Reclamation project on Clay Street is part of Lake County, Indiana’s 2018 road preservation plan.  Mix designs from, trusted industry experts, Midland Standard Engineering & Testing, Inc. determined the addition of 2.5% of emulsified asphalt to the top 6” of pre-pulverized asphalt and aggregate base would meet the design strength requirements set forth in INDOT ITM 594-17.

Customization of emulsified asphalt stabilizing agents binding RAP and aggregate base is vital to meeting specific project strength and curing criteria.  We turned to Tri-State Asphalt, LLC for their expertise in pavement preservation.  They provided and delivered the engineered asphalt emulsion that helped Rock Solid Stabilization complete the 45,484 SY project in a little over 3 days.

Top 5 Reasons to use Direct Water Injection when  Stabilizing Soil

1. Uniform Consistency — Direct Injection controls the precise application of water accurately to the exact percentage needed for the stabilized cross section to reach optimum moisture.
2.  Gravity — Water runs downhill and puddles in low spots, so when “top dressing” or applying water through a spray bar there is no guarantee the cross section is receiving the same application of water for the stabilized area.
3. Adjust for Overlap — Direct injection capabilities allow for the operator to control the width of the application area by activating or restricting water nozzles. (A remaining 4’ section can effectively receive the water without over hydrating the previously stabilized adjacent area)
4. Adapt to Changing Ground Conditions — Direct injection capabilities allow the operator to quickly adjust the amount of water applied to reach optimum moisture for the stabilized section. Project soils rarely retain the same moisture content or makeup throughout a site, so it’s important to be able to adjust for these different ground conditions.
5. Better Results & Strengths — When proper moisture is applied consistently the stabilized cross section is better controlled, more uniform, and stronger.

It’s not always possible to use direct injection, but when it is, it is the best way to add moisture to your stabilized section.  It’s the Rock Solid Way!
