Speakers: Dr. Amy Cerato, P.E. and Dr. Gerald Miller, P.E., both of the School of Civil Engineering and Environmental Science at the University of Oklahoma
Topics: This seminar will focus on three topics:
1) The state of the practice relative to selecting a stabilizer and determining the optimum additive content based on soil properties. Reference will be made to local practice and the use of Oklahoma Highway Department method OHD L-50.
2) Adverse reactions and unexpected outcomes from chemical stabilization. This part of the seminar will focus on adverse chemical reactions with particular emphasis on how to address soils containing sulfate. Discussions of techniques to measure sulfate content and methods for reducing sulfate induced problems in stabilized soil will be presented.
3) Determination of the additive content of compacted soils in the field. Methods of determining the amount of additive in soil samples obtained from the field will be discussed. Such methods are important for quality control/quality assurance considerations and for forensic investigations. Traditional methods as well as, a new and simple, yet powerful technique will be presented.
