Musharraf Zaman, Ph.D., P.E.

University of Oklahoma
Director-Southern Plains Transportation Center (SPTC)



Dr. Musharraf Zaman is the Aaren Alexander Professor of Civil Engineering and Environmental Science and Alumni Chair Professor of Petroleum and Geological Engineering at the University of Oklahoma. (OU). He has been serving as the Director of the Southern Plains Transportation Center (SPTC) – a consortium of eight universities in U.S. DOT Region 6 – for more than three years. He serves as the Editor-in-Chief of the International Journal of Geomechanics, ASCE and as the Executive Vice President of the International Association for Computer Methods and Advances in Geomechanics (IACMAG). He served as the Associate Dean for Research and Graduate Programs in OU College of Engineering for more than eight years.

Dr. Zaman has more than 35 years of experience in the areas of pavement materials and systems, geotechnical engineering, and geomechanics. During his tenure at OU, he has received more than $30 Million in external funding, developed two new laboratories (Broce Asphalt Laboratory and Asphalt Binders Laboratory), and published 172 journal and 224 peer reviewed conference proceedings papers and 12 book chapters. His projects have been funded by NSF, Federal Highway Administration, U.S. Department of Transportation, Oklahoma Department of Transportation, and the private sector. His work on intelligent compaction, along with co-workers, has been funded heavily by the private sector and received patents. He has supervised more than 80 master theses and doctoral dissertations to completion. His research papers have own international-level awards from IACMAG and Indian Geotechnical Society.

PRESENTATION TITLEClimate-Adaptive Surface Transportation Infrastructure: Development and Implementation of Innovative Technologies and Practices

PRESENTATION SUMMERY – With increased frequency and level of severe weather and climate extremes, innovative technologies and practices have become a key factor in developing and maintaining sustainable transportation infrastructure (pavements, bridges, and embankments). The Southern Plains Transportation Center (SPTC) – a consortium of eight universities in U.S. DOT Region 6 (Arkansas, Louisiana, New Mexico, Oklahoma, and Texas) – has been developing innovative technologies, materials, and methods for design, construction, maintenance, and monitoring of climate-adaptive transportation infrastructure. Examples include: web-based routing to reduce pavement damage; rapid and cost-effective rehabilitation; mixture design for pumpable concrete for extreme weather; intelligent compaction for real-time monitoring of compaction quality; risk-based life cycle management; and connected vehicle technology for severe weather warning. This presentation will provide an overview of some of the technologies and practices, with a focus on implementation.


Rongji Cao, Ph.D.

Chief Engineer- JSTI Group



Dr. Rongji Cao is chief engineer of JSTI Group. He is also the director of National Engineering Laboratory for Advanced Road Materials (NLARM). He got Ph.D. degree from southeast university in road and railway engineering. He has 20 years of experience in asphalt mixture design, quality control, pavement rehabilitation, asset management and new road materials. He has published over 50 papers and has 9 patents in recent years. He also engages in implementation of asphalt rubber in China and the asphalt rubber ambassador of Rubber Pavements Association (RPA). Dr. Cao is a technical member of World Road Association (PIARC), and member of International Society for Asphalt Pavements (ISAP).

PRESENTATION TITLEThe Development of Superpave Technology in China in 2 Decades

PRESENTATION SUMMERY – Superpave technology has been introduced to China for more than 20 years, we have experienced the introduction of equipment, technology digestion, pilot projects, widely promotion and technical improvement process, Superpave technology promotes the progress of asphalt pavement technology in China.

  • Superpave asphalt binder specification has been accepted by most highway agencies.
  • In most cases, Ndesign is 100 times for heavy duty pavement, not 125 times. Chinese mixture performance tests are used to verify Superpave mixture.
  • The Superpave mixture method is used in nearly 20 provinces; its idea influenced the revise of asphalt pavement specification in China. Many provinces have included Superpave in local specification.
  • SMA + Superpave structure has become one of the most typical structures of heavy traffic highway asphalt pavements.
  • There are more than 250 SGCs, and more than 40 sets of Superpave Blinder equipments in China. The product standard and product verification regulation of SGC were laid down.
  • Superpave pavements have been built in China for 16 years, and has been implemented over10,000 km, the LTPP study shows that Superpave pavement has a good road performance, especially the resistance to rutting.
  • Superpave has been integrated into China's asphalt pavement technology and refined together.
