Recycling is a concept that most of society supports as a practice that can benefit the environment and overall well-being, as well as reduce the needs and costs associated with raw materials. However, the conversation needs to shift from just recycling to responsible recycling. This is the focus of a feature article in the November-December 2020 issue of TRB's magazine, TR News (Issue 330). TR News  is TRB's bimonthly magazine featuring timely articles on innovative and state-of-the-art research an...

Asphalt binders experience aging that occurs in two distinct stages under quite different conditions: (1) short-term during construction (plant mixing, storage, placement, and compaction) and (2) long-term during the service life of the pavement. The TRB National Cooperative Highway Research Program's pre-publication of NCHRP Research Report 967: Asphalt Binder Aging Methods to Accurately Reflect Mixture Aging documents research conducted to improve laboratory binder conditioning methods to accurately si...

British–Hungarian Nobel Prize physicist Dennis Gabor wrote: “The future cannot be predicted, but futures can be invented." Considering in a reasonable and logical way what the implications of new technologies may be and acting on our conclusions is how the future is invented.

Laboratory testing and field experience have shown that highway concrete should be properly air entrained to resist the action of freezing and thawing, particularly in wet climates. Several gaps in the state of the knowledge still exist. The TRB National Cooperative Highway Research Program's NCHRP Research Report 961: Entrained Air-Void Systems for Durable Highway Concrete addresses these gaps and, more specifically, investigates innovative test methods for effectively characterizing the air system in f...

Pavement recycling is a technology that can restore the service life of pavement structures and stretch available funding for pavement rehabilitation. In general, pavement recycling techniques remix the existing pavement material and reuse it in the final pavement in the form of a stabilized layer. Limitations to further widespread implementation of pavement recycling processes have been reported in previous national research efforts. The TRB National Cooperative Highway Research Program's  NCHRP Re...

The year 2020’s raging coronavirus pandemic and reckoning with long-standing racial injustice led to widespread disruption and suffering, social unrest, and renewed calls for an accounting of our fragmented public health system and troubled history of racial inequity. The crises of 2020 transcend transportation yet also raise fundamental questions for it along with other sectors of our society and economy. In this addendum to Critical Issues in Transportation 2019 , the Transportation Research Board (TRB...
