Recycled pavement saves money and the environment. By Amy Epps Martin and Edith Arambula Ask just about anybody to name the most recycled material in America, and you’re likely to get some predictable responses: Aluminum cans. Plastic bottles. Glass bottles. Paper. Each guess is logical. And each one is wrong. That’s because 99% of reclaimed […]
TTI Associate Research Engineer Edith Arambula’s National Cooperative Highway Research Program project on evaluating the use of recycling agents was recently featured in an article for Asphalt Pavement. Taking RAP to the Max examines the barriers that prevent the use of reclaimed asphalt pavement (RAP), which is stockpiled throughout the country, and what can be […]

Plastic or paper. Decaf or regular. Cash or credit. Consumers make choices every day. Whether it’s about how we shop, how we dine, or how we purchase goods and services, most of our decisions are pretty straightforward. We know what we want, and we know why. When it comes to how we commute, however, things […]
Ensuring that asphalt binders don’t contain too many contaminates can be key to ensuring a longer-lasting roadway. The Texas Department of Transportation (TxDOT) is implementing use of an innovative technology in a new test method and updated specifications developed during a two-year study conducted by the Materials and Pavements Division of the Texas A&M Transportation […]
A week-long visit to Namibia by the leaders of the Texas A&M Transportation Institute (TTI) in October continued a longtime working relationship with that country but lays the groundwork for relationships with numerous other African countries. Agency Director Greg Winfree, Assistant Director Joe Zietsman and Associate Research Engineer Tara Ramani met with the country’s Roads […]
By Jolanda Prozzi The current tropical storm season has barely begun, and we’re still recovering from the last one, mindful of a few sobering realities: Weather and climate disaster events — which include hurricanes and other major flooding — are becoming more frequent. According to the National Oceanic and Atmospheric Administration, the U.S. suffered 203 […]

The practice of burying or placing utility lines without adequate documentation has caused large-scale problems across the country. It’s also helped create a new program devoted entirely to the issue. The Utility Engineering Program, formed last year at the Texas A&M Transportation Institute (TTI) to capitalize on the Institute’s two decades of leading-edge research and […]
ENCOUNTERING the same construction zones day after day, month after month, it’s only natural for travelers to ask “Why does this have to take so long?” Thanks to a growing reliance on creative thinking, it no longer does. That thinking is at the root of accelerated construction, an effort launched in Texas in 1998 and […]
The old adage, “Cheap, Fast, Good: Pick Any Two,” applies to most things. Defying this commonly held belief, rehabilitating a roadway with cold-in-place recycling (CIR) can actually be faster and cheaper than traditional methods and still yield outstanding results. CIR is a single operation. An existing deteriorated hot-mix asphalt (HMA) layer is recycled and treated, […]
By Gregory Winfree and Zachary Grasley In August, we mark 11 years since the Interstate 35 bridge in Minneapolis collapsed into the Mississippi River, killing 13 people and injuring 145 more. For anyone not living there, or otherwise not personally affected by that tragedy, the anniversary will likely pass without a single thought as to […]
Flooding has plagued Houston roadways for decades, but now, thanks to a first-of-its-kind warning system initiated by Houston TranStar and developed by the Texas A&M Transportation Institute (TTI), motorists will be warned in real time about locations where roadway flooding is likely occurring. View the Houston TranStar warning system “Houston was ground zero for Hurricane […]
A National Cooperative Highway Research Program (NCHRP) project describing a new mechanical-based method for testing aged asphalt led to international recognition for two Texas A&M Transportation Institute employees: Postdoctoral Researcher Meng Ling and TTI Research Engineer Robert Lytton. “An Inverse Approach to Determine Complex Modulus Gradient of Field-aged Asphalt Mixtures” was named a 2017 Best […]
