The Transportation Research Board (TRB) 94th Annual Meeting held this past January accepted several papers and posters from the University of Hawaii at Manoa’s College of Engineering including one from our very own Adrián Ricardo Archilla. His area of specialty in transportation engineering include: Transportation Infrastructure Management Systems, Pavement Engineering, Deterioration Modeling, Transportation Systems Analysis, Transportation Systems Analysis, Applied Statistics, and Traffic Engineering. Dr. Archilla will share with us his TRB presentation.
Top-down fatigue cracking is now recognized as a common type of distress occurring in all types of environments on heavy duty hot mix asphalt (HMA) pavements. The top-down fatigue cracking mechanism is not yet well understood and its modeling is limited in current state of the practice tools. Despite significant recent advances in its modeling, for regions with high temperature seasons, an extreme high temperature profile with depth is a potentially important factor that has not received enough consideration. This presentation explores the potential of temperature gradients caused by high pavement surface temperatures to induce top-down fatigue cracking.
