Paulding County, GA

AGENCY NAME

Paulding County, Georgia

PROJECT NAME & LOCATION

  • R.C. Thompson Road
  • Harmony Road
  • McGarity Road
  • Pleasant Grove Road

BACKSTORY

After visiting Gallagher’s HIR project for Bartow County, Georgia last summer, the forward-thinking folks at Paulding County knew they had to consider this process for their 2017 resurfacing needs.

AGENCY PROBLEM

Paulding County needed a cost-effective solution to resurface pavement and minimize reflective cracking.

GALLAGHER’S SOLUTION

Using the HIR process prior to adding structure resulted in further crack retardation—as compared to a simple overlay—and a significant cost savings too when compared to a thicker asphalt overlay.

Chisago County, MN

AGENCY NAME

Chisago County, MN

PROJECT NAME & LOCATION

Chisago County Heater Scarification Project

  • County Road 57 (from CSAH 30 to CSAH 9)
  • CSAH 18 (from CSAH 30 to CSAH 14)

BACKSTORY

After the successful completion of Hot-In-Place Recycling in 2016, Chisago County utilized HIR as a solution for their road resurfacing needs for a second, consecutive year.

AGENCY PROBLEM

Although the roads were structurally sound, Chisago County was looking for a solution to address reflective cracking and improve pavement “rideability.” In addition, the roads were showing signs of delamination on chip sealed pavements—all common aging issues. Chisago County needed an economical solution to work within their budget, but found that the options were limited with conventional methods available.

GALLAGHER’S SOLUTION

Heater Scarification rejuvenates old, worn-out asphalt, putting the “ride back in the road.” HIR resulted in improved “rideability” and provided a solution the for the road’s reflective cracking and delamination. Rejuvenating the existing asphalt in-place, with a chip seal overlay, resulted in additional savings and provided a cost-effective solution in Chisago County.

City of Rock Island, IL

AGENCY NAME

City of Rock Island, IL

PROJECT NAME & LOCATION

City of Rock Island Heater Scarification Project

  • 31st, 32nd, 41st, 42nd, and 43rd Streets (between 14th Avenue and 18th Avenue)
  • 35th, 39th, and 40th Streets (between 11th Avenue and 18th Avenue)
  • 12th Avenue (between 35th and 38th Streets)
  • 20th Avenue (between 5th and 9th Streets)
  • 17th Avenue (between 21st and 23rd Streets)

BACKSTORY

In 2016, Rock Island needed a cost-effective and time-sensitive solution to address their pavement issues. They contracted with Gallagher Asphalt on the Urban Heater Scarification project in the hopes that Hot-in-Place Recycling (HIR) was the answer. The city was so impressed with their new recycled roads they decided to renew their contract in 2017 and hope to continue the process into the foreseeable future.

AGENCY PROBLEM

Rock Island is an urban city in northwestern Illinois that faces the same issues so many other similar-sized cities face year after year—too many roads to fix and not enough money to fix them. Like many agencies, they were relegated to address their roads with a “worst first” approach, and year after year the available funds were exhausted before all their roads could be addressed.

GALLAGHER’S SOLUTION

Hot-in-Place Recycling. Simply put, Rock Island realized almost a 30% savings versus the cold in-place process they used in the past. In fact, in 2016 after utilizing HIR, the city was able to resurface all of their targeted streets.

City of Indianapolis, Indiana

AGENCY NAME

City of Indianapolis, Indiana

PROJECT NAME & LOCATION

City of Indianapolis Hot-in-Place (HIR) Recycling Project

  • Carroll Road (from Treasure Point to 86th Street)
  • Pike Plaza Road (from Moller Road to 450 W. Lafayette Road)
  • 30th Street (from Meridian Street to Central Avenue)
  • Martin Luther King Jr. Street (from 11th Street to 16th Street)
  • Brookside Avenue (from Hamilton Avenue to Olney Street)

BACKSTORY

The city of Indianapolis was searching for a more cost-effective alternative to resurfacing all the roads within their 2017 budget. The city’s Department of Public Works, working with AECOM consulting firm, decided to look into Hot-in-Place Recycling. By working with Gallagher Asphalt, the savings they attained—rather than using a traditional mill and fill approach—is enabling them to repair and resurface all the roads that were originally planned to be remediated.

AGENCY PROBLEM

Indianapolis needed to find a budget-conscious solution. Traditional methods were too costly. Plus, they wanted a solution that was environmentally-friendly and less disruptive to the residents and business community. Reducing user delays was crucial for them.

GALLAGHER’S SOLUTION

Using the HIR process, rather than a traditional 2” mill and fill, the city was able to take a progressive approach to remediating their streets in-place. They were also able to apply the substantial savings toward an additional 1.25” hot mix overlay afterwards and add structure. The structural gain will now increase longevity and alleviate pavement distress from heavy truck load traffic.

PROJECT NAME & LOCATION

Waukesha County Hot-in-Place (HIR) Recycling Project

  • County Trunk Highway (CTH) E (from CTH 16 to CTH VV)
  • CTH P (from CTH B to Fairview Road)
  • CTH Y (from Menomonee Avenue to CTH Q)

BACKSTORY

As the third-most populous county in Wisconsin and experiencing continual growth each year, Waukesha County needed a strategy that was sustainable and cost-effective. Known for “leading the way” through economic and environmental stewardship, they are on their 13th consecutive year recycling their roads with Hot-in-Place Recycling and have contracted nearly 2MM SYs worth since 2005.

AGENCY PROBLEM

Waukesha County is continuing to receive more truck traffic than ever before. They needed a solution to add additional structure and address their biggest challenge—fixing the roads’ reflective cracking beforehand. Responsible for over 400 miles of highways, they needed to find a way to stretch their budget and fix as many roads as possible each year.

GALLAGHER’S SOLUTION

Waukesha County put their plan into action, utilizing the HIR process to heat and recycle the existing asphalt in-place, resulting in an estimated $80,000-$140,000 savings per mile. HIR not only provided a solution to further retard the roads’ reflective cracking by performing the process before adding the necessary structural 2” overlay of hotmix, but it also saved time and money.

Atlanta, GA

AGENCY NAME

City of Atlanta, GA

PROJECT NAME & LOCATION

Multiple streets totaling 325,000 S.Y. spread out over all 12 council districts of the City of Atlanta, GA.

BACKSTORY

After visiting Gallagher’s HIR project for Paulding Co., Georgia. in June of 2017, Atlanta’s innovative and forward-thinking public works department. knew that HIR could benefit their resurfacing program.

AGENCY PROBLEM

The City of Atlanta needed a cost-effective solution to resurface older pavements and minimize reflective cracking.

GALLAGHER’S SOLUTION

Using the HIR process, prior to adding structure, resulted in further crack retardation and a longer lifecycle—as compared to a simple overlay. This combination of HIR with a thin wearing surface, also provided a significant cost savings when compared to a traditional mill and fill process, as well as less traffic interruption.

Cecil County, MD

AGENCY NAME

Cecil County, MD

PROJECT NAME & LOCATION

Connelly Road between Route 222 and Route 1.

BACKSTORY

With many rural roads in need of resurfacing and the cost of asphalt increasing, the agency used the HIR process for a cost-effective solution for their road resurfacing needs.

AGENCY PROBLEM

Many of the country roads within the county are in need of resurfacing. HIR is the solution that will allow the county to resurface more miles at a reduced cost and eliminate the need for milling. HIR also eliminates the need to purchase new asphalt, while bringing the roads back to like-new condition.

GALLAGHER’S SOLUTION

After using the HIR process, the road surface was brought back to like-new condition, increasing the drivability of the road making it ready for the final slurry surface treatment.
