Tailoring construction and repair solutions to unique problems along a discrete part of the roadway — instead of applying a one-size-fits-all method — is gaining popularity as a pavement design/rehabilitation method for entire corridors. It’s just one innovation that Texas A&M Transportation Institute (TTI) researchers are using to help the Texas Department of Transportation (TxDOT) […]
Using recycled materials on roadways has been standard procedure in construction for several decades. The challenge lies in having a practical mix design process — think of it like a recipe, selecting the right ingredients and proportions — that agencies responsible for highway infrastructure can rely on for guidance. The Texas Department of Transportation’s (TxDOT’s) […]
Hosted by the Texas A&M Transportation Institute (TTI), the Federal Highway Administration’s (FHWA’s) Sustainable Pavements Technical Working Group (SPTWG) met at The Texas A&M University System’s Center for Infrastructure Renewal (CIR), located at the A&M System’s RELLIS Campus, Oct. 30–31. The group’s stated purpose is to “provide technical input to the FHWA on sustainability and […]
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. […]
Construction defects in new asphalt layers often cause early pavement failures. Imagine a time when these are eliminated. “I think that time is here,” says Tom Scullion, manager of the Flexible Pavement Program at the Texas A&M Transportation Institute (TTI). Scullion is speaking of a three-step process (detailed in this article) that uses technologies developed […]
In recent years, there has been a boom of energy-related activities in Texas, but many short- and long-term impacts on the state’s right-of-way and infrastructure are not properly documented.
