By: Gregory Winfree and Zachary Grasley The subject of our nation’s infrastructure is once again prominent, both in the wake of the recent release of the American Society of Civil Engineers quadrennial report card on the state of America’s infrastructure and among our policymakers in Washington, D.C. The ASCE report card presents one of those […]
Increasing recycled materials content in asphalt mixtures has numerous economic and environmental benefits, but ensuring good performance has always been a challenge. That’s because stiff, brittle, heavily aged materials can result in premature cracking. This synthesis project sets the course for revising TxDOT’s Standard and/or Special Specifications to recognize this challenge. The TTI video production […]

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 […]
May 13-20 is the 7th annual Infrastructure Week. This year’s message emphasizes that America’s future will be shaped by the infrastructure choices we make today. So let’s #BuildForTomorrow.
