President's Report

Central Ohio  Section Members:

Christopher Nye

Our September lunch meeting was well worth the time to drive to Newark. Brad Lepper, Ph.D., from the Ohio History Connection gave an interesting talk about the Hopewell earthworks, and then we were able to visit them in person. It wasn't until I was standing in the middle of the earthworks that I could truly appreciate their size and the amount of effort and planning that had to go into their construction. Even today with all of our technology, I think it would be a challenging task to align the mounds with the rising and setting of the moon, as they did 2,000 years ago. Many thanks to our new member-at-large, Phil Hinson, for making the arrangements for the lunch and tour.

If you would like to see a few photos of our trip to Newark, you can see them on our new Instagram account, www.instagram.com/centralohioasce , or just search for CentralOhioASCE (all one word) and follow us.

I am pleased to announce that two members have stepped up to help the section out. Sheena Marston has volunteered to take over as newsletter editor, and Peyman Majidi will be our new secretary this year. I am truly grateful to them.

Finally, please join us for the October luncheon on October 18. If you are a professional engineer, you know that the new continuing education requirements include ethics training. We have John Greenhalge, the executive director of Ohio State Board of Registration for Professional Engineers and Surveyors, giving a talk on the laws and rules related to sealing engineering and surveying work product, including the use of electronic seals, how to protect your seal in accordance with Ohio law, and the penalties for plan stamping. I hope to see your there.

Webinars

GEOSYNTHETICS USED IN UNPAVED AND PAVED ROADS

Thursday, October 25, 2018, 12:00 PM - 1:30 PM
Resource International, 6350 Presidential Gateway, Columbus OH 43231
Register Here
->Free to Central Ohio Section ASCE Members
->Seating is limited to the first 25 people
->Bring your own lunch


Purpose and Background

Beginning in mid-1930, geotextiles and then geogrids have been used in unpaved and paved roads for the purposes of reduced stone base thicknesses and/or improved serviceability. Today, they are used primarily in four discrete applications. This webinar is subdivided accordingly. First, for use as unpaved road reinforcement, the theory is well developed such that benefit/cost of using geotextiles or geogrids can be assessed. This application is very well positioned and accepted. Second, the webinar reviews paved road stabilization and a number of geogrid design methods focusing on increased trafficability. Also presented is an observational approach to mitigate longitudinal cracks for paved roads under the assumption of lateral reinforcement. Third, for paved roads, geotextiles have been used as separators to keep the crushed stone base course from mixing with the soil subgrade, the theory is not well developed and reliance is on field studies. Fourth, the webinar describes both geotextiles and geogrids insofar as prevention of reflective cracks through asphalt overlays. Both theory and field behavior are presented.

Primary Discussion Topics

  • Introduction and Background
  • Unpaved Roads Reinforcement With Geotextiles or Geogrids
  • Paved Road Applications Using Geogrid Reinforcement
  • Paved Road Applications Using Geotextile Separators
  • Geotextile and Geogrid Interlayers for Asphalt Overlays
  • Summary and Conclusions


Learning Outcomes

  • Learn about the four major geosynthetic applications with respect to unpaved and paved roads
  • Learn how geotextiles and geogrids are involved depending on exactly where in the roadway cross-section they are placed
  • Learn about the quality of the soil subgrade
  • Design methodologies
  • The relevant test methods and procedures required for input data
  • Numeric examples of the required stone or asphalt thicknesses
  • What an owner or design consultant can realistically expect for long-term field performance


Webinar Benefits

  • Appreciate the very different applications of geotextiles and geogrids insofar as pavements are concerned
  • Understand how the soil subgrade, stone base course, and pavement material function vis-à-vis the specific geosynthetic and its location in the cross-section
  • Appreciate where design models are fully developed, moderately developed or quite nonexistent
  • Understand how laboratory test values of the geosynthetic material are used in the various design processes


Webinar Outline

  • Introduction and Background
  • Unpaved Roads Reinforced With Geotextiles or Geogrids
  • Paved Road Applications Using Geogrid Reinforcement
  • Paved Road Applications Using Geotextile Separators
  • Geotextile and Geogrid Interlayers for Asphalt Overlays

Purpose and Background
PVDs (also called wick drains) have become the most cost competitive method for consolidating deep deposits of saturated fine-grained foundation soils. For their proper utilization one must understand their installation, requisite theory, remaining issues and the opportunity of strengthening (not only dewatering) the soil mass. This webinar provides this specific knowledge.

Primary Discussion Topics

  • Overview of PVDs
  • Decription of installation, including the stresses mobilized during installation
  • Successive design theories of Terzaghi, Barron and Hansbo
  • Description of several issues and concerns that still remain
  • Discussion on the possibility of soil strengthening by PVD inclusions
  • Description of a new generic specification for PVDs


Learning Outcomes

  • Know what PVDs are, do, and how they behave
  • Understand the installation process and stresses that are involved
  • Recognize the analytic background required in the design process
  • Describe the remaining PVD issues and concerns
  • Be exposed to the soil strengthening capabilities of PVDs
  • Understand the tests and issues included in a generic PVD specification


Webinar Benefits

  • Gain an understanding of PVD consolidation and strengthening of soft, saturated fine-grained soil deposits
  • Recognize that there are issues to be overcome such as kinking, soil smear and reduction factors, all of which will be considered
  • Learn about a new, generic specification that is offered for use by owners and consulting engineers


Webinar Outline

  • Background and overview
  • Installation of PVDs
  • Mobilized stresses during installation
  • Terzaghi-barron-hansbo consolidation theories
  • Remaining PVD issues and concerns
  • Slope stabilization using the tensile strength of PVDs
  • Generic PVD material specification
