All airports have one thing in common: pavement, and a lot of it. In fact, in many cases, maintaining runways represents the largest expenditure at an airport. It’s critical that airport management inspect and maintain its pavements in a timely fashion for safety reasons and to avoid costly, full-pavement rehabilitation projects. Researchers at the Texas […]
There is one thing all airports have in common—pavement—and a lot of it. In fact, pavements represent perhaps the largest expenditures at any airport. Thus, it is critical that airport management inspect and maintain their pavements for not only safety reasons, but to perform timely maintenance in order to avoid costly full pavement rehabilitation projects.

Over the past 60 years, drivers have seen countless changes on Texas roadways — not only in how they’re used by drivers but in how they’re built and maintained. Yet one thing remains constant: the partnership between the Texas Department of Transportation (TxDOT) and the Texas A&M Transportation Institute (TTI). These two agencies work together […]
Training Courses Teach TxDOT Personnel Best Practices in Seal-Coat Projects The Texas Department of Transportation (TxDOT) maintains more than 79,000 miles of farm-to-market, ranch-to-market, state, U.S. and interstate highways. That’s more roadway than any other state. As resources are stretched thin, maintaining the roadways is a challenge. Seal coats — also known as chip seals […]
The truth is, nobody likes potholes. But when you’re responsible for the integrity of your roadways, finding the funds to proactively plan maintenance is difficult when limited resources are already stretched to the limit. Add to that challenge new energy developments bringing hundreds of heavy trucks to two-lane roads, and it doesn’t take long for […]
Roads in South and West Texas are taking a pounding from energy-sector traffic. The affected roads are most often narrow farm-to-market (FM) roads with thin-asphalt surfaces. They’re now carrying 20 to 50 times more truck traffic than they were designed for. Weigh-in-motion data indicate that many of these trucks are also overloaded. The Texas Department […]
Pavements With close to 80,000 miles of roadways in Texas, maintaining the pavements, whether asphalt or concrete, is a demanding and costly part of city, county and state responsibilities to keep our transportation system among the best in the country. When potholes, cracks and ruts appear and begin to degrade the pavement, it’s often too […]
TTI researchers have spent years refining thin asphalt overlay mixes that bridge the gap between high traffic loads and limited maintenance budgets.
