FORTA Professorship to expand ASU pavement engineering research

Over the past four decades the FORTA Corporation has built a reputation as a leader in the synthetic reinforcement fibers industry. Through a newly announced professorship at Arizona State University, researchers in the Ira A. Fulton Schools of Engineering will work with FORTA to continue advances to develop stronger pavement materials that make roadways safer and more durable.

The FORTA Corporation has achieved its status as an industry leader in large part because the company has gone beyond merely manufacturing and supplying its product to the construction, concrete and asphalt industries. FORTA has also put significant effort and investment into innovating the synthetic fibers that are used to strengthen pavements and other building materials, becoming one of the “pioneers in the applications of fiber reinforcement,” says Martin Doody, the company’s vice president of asphalt sales.

“We were the first company to introduce an actual reinforcement for concrete in the United States. We were the first company to introduce reinforcements for asphalt pavements,” Doody says. “Although we’re not the largest company in that market, we like to think that we’re the leaders in the research and development of fiber technology.”

One of the bigger leaps forward in the company’s endeavors got off the ground in 2006 when FORTA was working on a project with The Boeing Company in Arizona to implement the use of synthetic fibers in asphalt pavement. For expertise in lab work and testing, the company turned to a local source of expertise: Arizona State University engineers.

The project would result in a research breakthrough and an extensive report detailing the discovery of a new way to use synthetic fibers to boost the performance of pavements, Doody says.

Enhancing a productive relationship

The success of that project opened the doors to a series of collaborations between Pennsylvania-based FORTA and several faculty members and postdoctoral researchers in the Fulton Schools.

Among the first involved was Kamil Kaloush, a professor of civil, environmental and sustainable engineering in the School of Sustainable Engineering and the Built Environment, one of the six Fulton Schools.

The productivity of that working relationship over the years has earned Kaloush the distinction of being named the first FORTA Professor of Pavement Engineering, a designation that supplies Kaloush and his lab with $250,000 over the next five years to support scholarly activities. The professorship funding is part of an overall investment of $1 million by FORTA over five years that will also fund research and support for a postdoctoral researcher.

Kaloush directs of the National Center of Excellence on SMART Innovations at ASU — SMART stands for sustainable materials and renewable technologies.

His expertise in pavements and materials has earned him several professional accolades, including the Rubber Pavements Association Outstanding Research Award. It also brought him into leadership positions with the federal Transportation Research Board’s Design and Construction Group Executive Board, the International Road Federation, the Rubberized Asphalt Foundation and the Arizona Council for Transportation Innovation, among other similar roles.

Kaloush, who is also affiliated with ASU’s School for the Future of Innovation in Society and Urban Climate Research Center, is a leading member of the Fulton Schools Pavement Analysis and Design Group. For many years, he has led the nationally prominent Arizona Pavements/Materials Conference that brings about 400 professionals to ASU annually.

Pavements play an important role in the world’s transportation infrastructure. Globally, about 90% of roadways are made of asphalt mixtures. In the United Sates, more than 500 million tons of asphalt mixtures are produced annually at a cost of $40 billion dollars, Kaloush says.

“So, it’s critical to have pavements that are less susceptible to deformation, cracking and damaging temperature effects,” he says. “This will translate into road-user benefits such as better ride quality, lower maintenance costs and safer roadways.”

Collaboration designed to fuel innovation

FORTA notes Kaloush’s contributions to developing and directing valuable research projects, collaborating with global research leaders and performing effective evaluations of methods, technologies, systems and products related to his field.

Kaloush’s work with FORTA to date has expanded fundamental knowledge in the pavements field, opening the way to innovations in pavement design, fibers composition and using fibers to extend the life of pavements.

Kaloush, who had 15 years of industry experience before earning his doctoral degree at ASU, says he has a “strong belief in the value of industry collaboration to create excellence” and views the FORTA Professorship and research endowment as “truly an honor and highlight of my academic career.”  

FORTA’s support “recognizes the tireless efforts, intensive industry engagement and impactful scholarly contributions Kamil has led for over two decades at ASU,” says Professor Ram Pendyala, director of the School of Sustainable Engineering and the Built Environment. “He has established a global reputation for ASU in pavement engineering and smart materials.” 

ASU engineering colleague Professor Mike Mamlouk points also to Kaloush’s talents as an educator, saying he brings a strong commitment to his work in both the lab and the classroom. In particular, Kaloush’s successes reflect a combination of his abilities to be both a strong leader and an effective team player, Mamlouk says.

“Kamil has accomplished something exceptional by bridging researchers, industry and government for a common cause,” says Fulton Schools Associate Professor Hasan Ozer, whose research focus aligns with Kaloush’s pursuits. “Kamil has earned the trust of everyone among his colleagues and those under his leadership. The friendly environment in his laboratory is an inspiration that enables students and researchers to thrive.”

FORTA executive Doody says the company has already benefited from Kaloush’s work on technological advances that enable more precise measurement and evaluation of the performance of pavements and the impacts of the uses of synthetic fibers.

“There are very few people we know of in the industry who have as good a grasp on what is entailed in achieving this kind of breakthrough progress,” Doody says.

Research support cements partnership

FORTA is confident Kaloush will continue to improve on how fiber reinforcement can strengthen the resilience of pavements and other construction materials, Doody says.

He is also impressed by progress in the field already being made by Hossein Noorvand, the civil, environmental and sustainable engineering postdoctoral researcher who will receive FORTA’s funding.

After listening to Noorvand’s doctoral dissertation presentation and meeting with him, Doody says he sees potential for Noorvand to rise to the caliber of other ASU researchers who have collaborated with the company. 

With researchers like Kaloush and Noorvand, he says, “I see us continuing the partnership with ASU for many years.”

As FORTA’s liaison for its venture with ASU, Doody is “genuinely passionate” about helping students be better prepared for their engineering careers, Kaloush says.

The company’s support to date has aided undergraduate and graduate student work activities, funded the purchase of testing equipment and sponsored travel to national and international conferences, as well as connected ASU researchers with key industry organizations and partners.

New funding will be used for faculty enrichment and to continue updating laboratory facilities, hire students, provide scholarships and support research, travel, curriculum development and community outreach and to advance innovative project ideas.

FORTA’s funding will aid the long-term goal “to push the boundary and productivity of FORTA fibers in pavement rehabilitation and construction,” Kaloush says. “It is a credible and cost-effective technology to improve the quality and durability of asphalt pavements.”
