“This research helps to confirm the direction the department has taken with recent changes to longitudinal joint specifications.”

How to Create Better Longitudinal Joints?
The longitudinal joint is the Achilles’ heel of every paved road. Road managers know the first part of the pavement to fail is the longitudinal joint. As the road’s most permeable part, this joint is susceptible to the elements, especially with their inherently lower density. Air and water work down through this unavoidable seam in the pavement causing the joint to deteriorate, crack, and pothole. And when the longitudinal joint fails, the rest of the road soon follows — triggering the need for even more maintenance and costly repairs.
Toward Zero Deaths (TZD) is a national initiative to eliminate highway fatalities founded in 2009. The ATSSA Foundation’s mission is to support injured or fallen roadway workers and their families, impacted by roadway work zone crashes. This national strategy on highway safety to advocate for eliminating serious injuries and death on our nation’s roadways was conceptualized by safety practitioners, researchers, advocates, and others from a variety of disciplines. This initiative calls for all stakeholders to champion the idea that one death on our nation’s roadways is too many, and we must all work together to bring the annual number of roadway deaths to zero. With this input of over 70 workshop participants and further discussions with the Steering Committee following the workshop, the name of this effort became “Toward Zero Deaths: A National Strategy on Highway Safety.”
Frequent donator, Minnesota-based company 3M raised more than $15k this year partnering with The ATSS Foundation by operating the zero deaths pledge wall from the start of the year through ATSSA’s 52nd Annual Convention & Traffic Expo. The company offered to match donations up to $5,000 and most of the raised funds came in during the final days of the Expo. “As the new ATSS Foundation Chair, I can’t express enough how grateful I am for support from companies like 3M that share the vision with us to help families that have experienced such horrific work zone tragedies,” said Kevin Shelton.

National Work Zone Memorial
Honoring those who died in work zones with a traveling & virtual memorial, The ATSSA Foundation offers the National Work Zone Memorial, honoring lives lost in work zones to help make fatalities “real” to policy makers and drivers. Originally unveiled in April 2002, “The National Work Zone Memorial – Respect and Remembrance: Reflections of Life on the Road” program is a living tribute to the memory of lives lost in work zones2. The new design of the traveling National Work Zone Memorial was unveiled in February 2017.
The traditional Memorial travels to communities across the cross each year to raise awareness of the need to respect and stay safe in America’s roadway work zones. A virtual National Work Zone Memorial is also available for meetings and events and is open to anyone interested in increasing roadway safety awareness and is now available at no cost. The Foundation encourages ATSSA members, ATSSA chapters, state DOTs and industry leaders to host the Memorial at your next event. To apply to host the Memorial at your next event, or to submit a name for the memorial, visit ATSSA webpage for more information.
Roadway Worker Memorial Scholarship Program
A work zone tragedy shouldn’t mean the end of the dreams and aspirations for the worker’s spouse, children, and family. This is exactly why The ATSS Foundation created The Roadway Worker Memorial Scholarship Program. This program provides financial assistance for post-high school education to the children or spouse of a roadway worker killed or permanently disabled in a work zone incident. The scholarships, offered by The American Traffic Safety Services (ATSS) Foundation3, can help put the worker’s dependents on the road to a brilliant future. The scholarships are competitive and have a value up to $10,000. Applicants who demonstrate a strong commitment to volunteerism may be eligible to receive an additional $1,000 in honor of Chuck Bailey, an esteemed member of the roadway safety industry from Ohio who died in 2002 as a result of a work zone incident.
The Roadway Worker Memorial Scholarship Program celebrates its 20th anniversary this year and has awarded $358,000 since its inception. Thirteen students are currently attending college thanks to a Roadway Worker Memorial Scholarship. Two of those also received a Chuck Bailey Memorial Scholarship for this school year. Hear from Roadway Worker Memorial Scholarship recipients about how The ATSS Foundation scholarships helped them achieve their dreams.
“It is a privilege to help the dependents of fallen or permanently injured roadway workers pursue their goals,” said Foundation Director Lori Diaz. “But we couldn’t offer these scholarships without the generosity of individual donors, ATSSA members and sponsors of the events we hold throughout the year.” The ATSS Foundation is the charitable arm of ATSSA and was formed in 1988 with the core purpose to promote roadway safety through charitable giving and public awareness programs.

In March of 2019, the National Lieutenant Governors Association (NLGA)4 passed a resolution recognizing April 8 – 12 2019 as National Work Zone Awareness Week. The resolution was passed at the NLGA 2019 Federal-State Relations Meeting where the lieutenant governors discussed state, federal, and international affairs. ATSSA’s Government Relations staff members were in attendance and requested the resolution be considered by NLGA. The NLGA is a professional association for the elected officials first in line of succession to governors in all 50 states and five U.S. territories. Their goal? The NLGA strives for efficiency in state government by providing professional support, to foster interstate cooperation, and to generally improve the efficiency of state and territorial administration through education on issues and leadership training. “ATSSA is pleased that the Lt. Governors passed a resolution acknowledging the importance of work zone safety awareness as we begin the spring construction season. Public awareness is key in helping to remind motorists to be mindful when navigating work zones,” said ATSSA’s Director of State Government Relations Ashley Wieland.
Many states are looking for methods to improve longitudinal joint performance of their pavements, since these joints often fail before the rest of the surface. With the inherently lower density at the longitudinal joints we often see pavements fail by cracking, raveling, and potholing. Lower density is synonymous with higher air voids which leads to premature failure of pavements due to the intrusion of air and water. Studies have shown that longitudinal joints in pavements are often the weakest areas of a road. (1)
Several state DOTs (Department of Transportation) are now using a materials approach to seal the longitudinal joint region by filling these air voids with asphalt content from the bottom up.
The materials approach is referred to as VRAM(2), a Void Reducing Asphalt Membrane. VRAM is a highly polymer-modified asphalt cement that is placed at the location of a longitudinal joint before paving. As mix is paved over it, the VRAM melts and migrates up into voids in the low-density mix, making the mix impermeable to moisture while sealing the longitudinal joint itself.
Illinois Department of Transportation (IDOT) test pavements were evaluated after 12 years and found to have longitudinal joints that exhibited significantly better performance than the control joint sections and were in similar or better condition than the rest of the pavement. Laboratory testing of cores showed decreased permeability and increased crack resistance of mix near joints with VRAM as compared with similar mix without VRAM. The life extension of the joint area is approximately 3–5 years, and the benefit is calculated to be three to five times the initial cost.
This project’s VRAM application began at 8:05pm with ProTack operating the 05-distributor shooting from the driver’s side. They started at address N3362 in the eastbound lane. Ambient temperature was 61F and existing pavement was 80F. ProTack applied a straight and consistent line throughout the project. VRAM width was measured with an average of 18 inches. (3)
The paving crew started at 11:40. Paving equipment consisted of a Volvo P7170B paver, Sakai SW850-II – 12-ton breakdown roller and a Volvo DD25B-5-ton finish roller. Width was 12 feet. Mix temp was 275F under the screed.
J-Band® is a VRAM product from Asphalt Materials, Inc. and was created in the labs of the Heritage Research Group.
J-Band has been helping roads last longer since 2002. VRAM has been used in 20 states and the District of Columbia.
