TECHNICAL PROGRAM

Designing Bases and Subgrades for Better Pavement Performance

Speaker: Robert L. Lytton, Ph.D., P.E. Professor of Civil Engineering at Texas A&M University, Bryan TX, Tel. No. 979-845-9964.

Dr. Lytton is an Honorary FPA Life Member, FPA Structural Committee Member, Professor of Civil Engineering in the Zachry Civil Engineering Department of the Texas A&M University and a Licensed Professional Engineer in Texas with a Ph.D. in Civil Engineering from the University of Texas (1967). 

Dr. Lytton is internationally recognized for his work in the study of the effect of expansive soil on foundations and pavements, having given presentations on the subject worldwide, most recently as the keynote speaker at the 2nd Transportation Research Congress in Beijing, China in May 2017. The same Research Congress hosted a symposium that was named in his honor, called The 2nd Transportation Research Congress Symposium in Honor of Robert L Lytton.  In August 2017, at the International Conference in Philadelphia, Pennsylvania, ASCE’s Transportation and Development Institute (T&DI) bestowed its 2017 Francis C. Turner Award on Dr. Lytton for his advancements and innovation of pavements design and construction. 

Dr. Lytton has selflessly presented to this FPA forum at least 15 times and he has also presented in past FPA seminars.  

PRESENTATION SUMMARY

Dr. Robert LyttonThe National Cooperative Highway Research Program (NCHRP) of the National Academies of Science acknowledged that subgrades and base courses have a major effect on pavement performance. In the past engineers had used primitive models to model subgrades and base course that resulted in a mismatch between design and performance. The NCHRP went out for bids for R&D on how to improve the modeling of pavements, base courses and subgrades to better represent what is experienced in the field. TAMU was awarded the project and is nearing completion of its study. TAMU’s study results are the subject of Dr. Lytton’s presentation.

TAMU’s study included models of reinforced / unreinforced concrete and asphalt pavements. The primary variables in TAMU’s newly developed pavement design procedure affecting pavement performance were load, moisture and temperature. Dr. Lytton will present interesting new results in pavement/base/subgrade performance relationships, particularly with respect to pavement joints in reinforced and unreinforced concrete pavements, and the use of geosynthetics in reinforcing base courses. He will also show that using radar, it may now be possible to determine the percent of lime or cement that was installed in stabilized base courses, something that has not been done before.

WHO SHOULD ATTEND?

Pavement Engineers, geotechnical engineers, foundation design engineers, pavement contractors, forensic engineers, city, county and state engineers, building owners, and others interested in improving the performance and life of pavements.
