Cement Stabilization for Road Bases and Soil
Presented by Mr. Randy Bowers, P.E., with Cement Council of Texas
BIO: Randy Bowers is the Director of Cement Stabilization for the Cement Council of Texas. He is a professional engineer with 35 years of service at TxDOT, where he served as Area Engineer in Tarrant County and Assistant Director of Maintenance for the Fort Worth District. While in the Johnson County Area Office, he served as the Area Engineer and Assistant Area Engineer where he constructed numerous cement stabilized pavements. Previously as a planning/design engineer, he directed analysis and testing and submitted numerous pavement design reports and recommendations for the Fort Worth District Randy now focuses on offering (at no cost) concrete and cement related solutions and support for end users.
ABSTRACT: This presentation will discuss the benefits of cement stabilization for pavements. As the nation’s infrastructure ages, agencies at all levels are tasked with maintaining and rehabilitating their infrastructure. Sustainable engineering technologies in pavement rehabilitation, such as full-depth reclamation (FDR), could be the answer for agencies in their quest to provide taxpayers with high-quality infrastructure while being good stewards of public funds. Full-depth reclamation of asphalt pavement is a rehabilitation method that involves recycling an existing asphalt pavement and its underlying layer(s) into a new base layer. The FDR process begins with using a road reclaimer to pulverize an existing asphalt pavement and a portion of the underlying base, subbase, and/or subgrade. Usually, the pulverized material is uniformly blended with an additional stabilizing material such as cement to provide an upgraded, homogeneous material. Finally, the stabilized material is compacted in place with rollers. The result is a stiff, stabilized base that is ready for a new rigid or flexible surface course. This presentation introduces the FDR with cement process and discusses issues related to project selection, design, construction, testing/quality control, and the latest innovations. The Cement Council of Texas presentation will equip engineering consultants with facts and information to work with their clients to make long lasting and economical pavement stabilization decisions. Designers and builders of Highways, Streets, Parking facilities, and Runways will benefit by improving their knowledge of the processes and techniques demonstrated in our presentation.

Disaster Management and Rapid Recovery Plans Integrated with New Technologies
Presented by Dr. C. Vipu, P.E., with the University of Houston Center for Innovative Grouting Materials and Technology and Texas Hurricane Center for Innovative Technology
BIO: Cumaraswamy Vipulanandan (Vipu) is an endowed professor of civil and environmental engineering at the University of Houston, Houston, Texas. He is the Director of the Center for Innovative Grouting Materials and Technology (CIGMAT) and the Texas Hurricane Center for Innovative Technology (THC-IT). He was the Department chairman from 2001 to 2009. Earned his MS and PhD in Civil Engineering from Northwestern University. He was the Principal Investigator or Co-Principal Investigator for over 80 funded projects since 1984 amounting to over $13 million. His research areas include, geotechnical, foundations, materials, environmental, disaster management, rapid recovery, artificial neural network and modelling. One focus area of the research is related to development of highly sensing smart cement and smart grouts with real-time monitoring system for applications in oil and gas industries and civil infrastructure industries. Also has developed a new nondestructive method to detect and quantify surface and bulk corrosion. Recently he has developed the Vipulanandan Rheological Model to characterize the fluids including drilling muds and cement slurries and the model is being used around the world. He has also developed the new Vipulanandan Failure Models for rocks, soils and concrete. He has graduated 35 Ph.D. and 90 Masters students (with thesis). He was the editor for seven books published by the American Society of Civil Engineering and American Concrete Institute. Recently he received two patents on “Smart Cement” and “Detection and Quantification of Corrosion in Materials”. He was selected as the Most Valuable Professional (MVP) in 2011 by the U.S. underground infrastructure industry. He has also received several national, state and local awards for his research, teaching and service.
ABSTRACT: In recent years, natural disasters (hurricanes, flooding, winter storms, tornadoes, fires, swelling soils) and human made disasters (accidents, pipelines failures) including cyber-attacks have become a major problem in power failures of critical operations such as water supplies, hospitals, transportation systems, oil supplies, constructions and also charging electric cars and other vehicles. Hence there is a need for developing resilient systems for multiple disasters with alternative methods of electricity production from small scale to large scale taking into account both natural and human made disasters to minimize major disruptions in multiple operations and also the losses in the time and revenue. Also, lessons learned from the past multiple disasters will help in preplanning (PP), disaster response (DR) and rapid recovery (RR). Also new technologies must be integrated with all of the operations to be very effective.
