Topic: “Performance Engineered Concrete Pavement Mixtures (PEM) – Concrete Pavement Performance System (CPPS)”
Edit TextDelete Text
Kevin Wentland P.E. is currently the Regional Business Development Manager, Concrete Division for Astec- CEI Enterprises. He has more than 30 years of experience in the planning, design, and construction of large industrial and commercial developments across the US. Over twenty years ago, Mr. Wentland, implemented a program of Roller Compacted Concrete (RCC) pavement that was utilized nationally initially as a solution to replace failed pavements within large 20 plus acre facilities with daily traffic in some cases in excess of over 800 semi-truck daily on facilities operating 24/7 365 days a year. The use of RCC was expanded for pavement of industry/commercial developments including use within facilities for the slab-on- grade.

Kevin is a fellow of the American Concrete Institute and a member of ACI Committees 327 Roller Compacted Concrete Pavements, 230 Soil Cement, 522 Pervious Concrete Pavements, and 325 Concrete Pavements. Kevin is also a member of ASCE Coasts, Oceans, Ports, and Rivers Institute Ports and Harbors Committee - Port Pavement Task Committee. For 3 years Mr. Wentland utilized his experience with these performance engineered concrete mixtures (PEM) and the equipment requirements to help Astec CEI Enterprises, Inc. develop a new concrete mixing equipment to support “better concrete” production and expand the use of these emerging “cement-binder material” pavement processes

Title:  Military Pavements in Texas 

 
Presentation Summary:
The 2005 Base Realignment and Closure Act dramatically affected the Corps of Engineers military construction program.  The BRAC proposal recommended the closing of 33 major military bases and the “realignment” (either shrinking or enlarging) of 29 other military installations. The state of Texas was a primary benefactor of these realignments.  The BRAC military construction program in Texas, valued at $4.78 billion, directly affected the way of life for the El Paso and San Antonio, Texas communities .  At Fort Bliss, we witnessed the one of the largest expansion plans in the history of the US Army. In San Antonio, one of the largest medical training campuses in the Department of Defense was constructed to upgrade existing medical centers to treat our wounded warriors from the Iraq and Afghanistan theaters of war. The purpose of this presentation is to focus on pavement construction projects that occurred at Fort Bliss, Fort Sam Houston, Fort Hood, and Laughlin AFB during this massive construction program and realignment process. Pavement processes and problems encountered during these projects will be featured and discussed.

Title:  Twisted Steel Micro Reinforcement (TSMR) and Cement Hydration Catalysts 

 
Presentation Summary:

TSMR is a new high performance concrete reinforcing technology that allows for steel fibers to serve as a primary reinforcement.  TSMR was developed over 15 years ago by the Army Corp of Engineers at the University of Michigan.  TSMR achieves six times higher pull out resistance then ordinary fibers and has a ductile response similar to rebar.  It is the only reinforcing type that increases the pre-crack strength of concrete.

Intercellular Cement Densification or ICD is a cement hydration technology that can be added to new concrete or applied to existing concrete.  Cement hydration is a very inefficient process and only 50-60% of mix water is normally utilized.  ICD based products act as a catalyst to the hydration process and enable greater then 90% hydration.  The resulting concrete is much denser, has ultra low permeability and significantly higher durability then ordinary concrete.

Title:  Thermally Induced Failure of Calcium Aluminate Sewer Repair

 
Presentation Summary:  If you ever specify novel repair materials on your projects, this presentation will be of interest to you.  This presentation describes an unusual failure of a calcium-aluminate repair to concrete sewer walls damaged by sulfuric acid.
A concrete repair project was performed at series of large manholes for the city of Austin. Part of the way through an apparently successful repair operation, shotcrete applications started to debond soon after application.  Preliminary investigation concluded that poor surface preparation and application errors were the cause of the debonding.  Results of a more detailed investigation concluded that a significant thermal-stress event within the first 24 hours was the primary cause.  This presentation discusses the investigation, mechanisms behind the failure, and the impact of project specifications on preventing future failures.

Effects of Warping and Curling of Jointed Plain Concrete Pavement
on Ride Quality
 
Presented By:
Daniel Butler, Graduate Engineer
Fugro Consultants, Inc.
 
Curling and warping of jointed concrete pavements have been interpreted to affect the ride quality of roads.  This common phenomenon of pavement distress will change in severity both daily and annually with regards to the temperature fluctuations the pavement undergoes.  A study was conducted by the Western Region support contractor using data from the Long Term Pavement Performance program to evaluate the effects of curling and warping on ride quality over a 16 year period.  The analysis showed that curling and warping plays a significant part in the perceived roughness of the roadway, and that ride quality can change significantly even through the course of a single day. Curling and warping of pavements should be considered when evaluating the roughness of a roadway, especially when project acceptance incentive/disincentive criteria are included. This presentation summarizes the study results and an evaluation method for determining the roughness of a jointed pavement without curling effects.
 
Mr. Butler is a Graduate Engineer in the Austin Pavements Group with Fugro Consultants, Inc., previously from the Washington, DC area where he pursued a Master’s Degree in Pavement and Geotechnical Engineering from University of Maryland, College Park, Daniel has worked in Fugro's  Austin office since May 2012.
