By Bill Stockton This article was originally published in The Texas Tribune, November 14, 2018. Your car’s next tank of gas is on its way to you. You can be assured of that, even though the journey it takes to get there is a sometimes arduous one. That journey could begin at one of hundreds […]
Decisions, Decisions: Lane Choices Aren’t as Simple as We Thought
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 […]
Fingerprinting Asphalt: New Handheld Testing Device Ensures Binder Quality
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 […]
TTI Travels to Africa for a Transportation Improvement Expedition
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.

Faster, Safer, Less Expensive Road Construction Through Utility Engineering
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 […]
Double Time — Accelerated Construction Strategies Enable a Quicker Pace Toward Project Completion
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 […]
Cheap, Fast, Good: Cold, In-Place Recycling Can Deliver All Three
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, […]
