SUMMARY:Online Workshop on Embankments and Their Interaction with Structures and Subsurface Utilities
DESCRIPTION:Embankment fills are commonly used to meet the vertical grade requirements of a facility. Fills placed to accommodate the vertical profile as the roadway approaches a bridge are often referred to as “approach embankment fills” or “approach roadway fills.”  Embankment fills are also needed for many other infrastructure projects. Deformation and instability (local or global)\, both vertical and lateral\, of embankment fills are common problems. Consideration of the effects of such fills on structures founded on fills\, adjacent structures\, and subsurface utilities is important to avoid costly post-construction maintenance and potential legal issues; e.g.\, approach embankment fill deformation near a bridge structure leads to the ubiquitous “bump at the end of the bridge.”  This workshop discusses the mechanisms of internal and external deformation in embankment fills. Evaluation of subsurface stresses and slope stability aspects related to embankment fills is also discussed. Estimation of the ground compaction factor is discussed\, which is a key element for the determination of final earthwork quantities.  Good practices for ensuring the stability and performance of a bridge structure’s approach elements are discussed.  Practical design solutions to mitigate the embankment stability problems will be discussed. \nUsing a collaborative and interactive learning approach\, this virtual workshop will help you understand: (a) design elements for embankment fills\, and (b) the effect of embankment fills on structures in fills\, adjacent structures\, and subsurface utilities. The workshop will help you assimilate these crucial considerations through active participation\, frequent interactions\, and real-time expert feedback. These interactions will help you better understand the nuances of design and construction procedures\, so you can avoid costly errors in real-world projects. Between the two live sessions\, attendees will work independently on an application (e.g.\, exercises) or a reflection (e.g.\, reading) assignment. \nSESSION 1 \n\nIntroductions\nConfiguration of embankment fills\nGeneral concepts of stress and strain\nEstimating stress distribution in foundation geomaterials\nNarrow versus wide embankment fills\nConcepts of lateral squeeze\nSlope stability considerations\nEstimation of internal and external deformations\nReview of Session 1\nInteractive Question and Answer (Q&A) session\nAssignemnt of classwork\n\nSESSION 2 \n\nReview of classwork\nBridge abutment configurations (e.g.\, stub\, open\, integral\, MSE\, etc.)\nEffects of fills on bridge abutments\nEffects of fills on approach slabs\nEffects on subsurface utilities\nSelection of embankment fill materials\nCompaction procedures and induced stresses\nSuggestions for geotechnical investigations\nSuggestions for mitigation of embankment stability problems\nReview of Session 2 and full workshop\nInteractive Question and Answer (Q&A) session\nAdjourn

SUMMARY:Online Workshop: Soil Nail Walls - Design and Construction
DESCRIPTION:Soil nailing technology is versatile and has been widely used worldwide over the last 3 decades for temporary and permanent excavation support. The design and performance of soil nail walls are intricately linked with their construction procedures.  To avoid adverse performance issues\, design and construction processes for a soil nail wall must be tailored to specific geometry and the environment (conditions) expected over its specified lifetime. This workshop will help participants gain a better understanding of design and construction procedures using limit-state concepts\, aligned with the latest guidelines based on the Load and Resistance Factor Design (LRFD) methodology of the American Association of State Highway Officials (AASHTO) and the Federal Highway Administration (FHWA). The contrast between LRFD and Allowable Stress Design (ASD) methodologies will also be included. Design and construction (including field testing) aspects of Solid Bar Soil Nails (SBSNs) and Hollow Bar Soil Nails (HBSNs) will be discussed. \nUsing a collaborative\, interactive learning approach\, this virtual workshop will help you understand the design and construction of soil-nail walls. You will learn new design approaches based on the LRFD platform\, which underpins the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA) guidelines for soil nail walls. The workshop will help you assimilate the design and construction aspects through active participation by frequent interactions throughout the workshop and real-time expert feedback. These interactions will help you understand the nuances of the newer design principles and avoid costly design errors in real-world projects. Between the two live sessions\, attendees will work independently on an application (e.g.\, exercises) or a reflection (e.g.\, reading) assignment. \nSession 1 of 2 \n\nIntroductions\nTerminology\, construction steps\, applications\, and explorations\nLimit states\, load factors\, and resistance factors\nService limit state (wall movements)\nStrength and Extreme Event limit states\nLimit Equilibrium (LE) analysis software tools\nCorrosion Considerations\nFacing (shotcrete)\nReview of Session 1\nInteractive Question and Answer (Q&A) session\nAssignment of classwork\nAdjourn for classwork and break\n\nSession 2 of 2 \n\nRoadmap for Session 2\nReview of classwork assignments\nInformation for plans and specifications\nNail types and construction processes\nGrout and grouting\nNail testing and nail acceptance criteria\nClosure and References\nReview of Session 2 and full workshop\nInteractive Question and Answer (Q&A) session

SUMMARY:Online Workshop on Compaction of Soils and Engineering Properties of Compacted Soils
DESCRIPTION:In the construction of highway embankments\, earth dams\, retaining walls\, structural foundations\, and many other facilities\, loose soils must be compacted to increase their densities.  The principal objectives in compacting soil are normally to create fill of high strength and low compressibility\, and\, in the case of water-retaining fill\, of low permeability. The ultimate goal is to construct safe earth structures that can provide the desired serviceability over their design lifetimes and minimize long-term maintenance. This workshop discusses the conventional (e.g.\, Proctor) methods of compaction and alternative methods of compaction based on soil air voids and shear strength (SAV&S) principles. It evaluates applicability of compaction procedures for various soil landforms (e.g.\, residual vs transported) soils. It also discusses implications of laboratory tests on field compaction specifications and properties of compacted soils such as shear strength\, volume change\, and permeability. It evaluates the concept of cohesion component of shear strength in compacted soils. \nUsing a collaborative and interactive learning approach\, this virtual workshop will help learners understand challenges associated with specification and construction of safe and serviceable compacted soil structures that will also help long-term maintenance needs. Learn new concepts of soil compaction that builds upon your prior knowledge and through active participation you will integrate the new knowledge into your understanding. You will also generate new ideas through brainstorming and discussion and develop a better understanding of the practical methods and processes of soil compaction\, learn about real-world problems that your peers encounter on projects\, and solutions they have implemented\, and receive real-time expert feedback. In between the two live sessions\, attendees will independently work on an application (e.g.\, exercises) or a reflection (e.g.\, reading) assignment. \nSession 1 \n\nIntroductions\nTerminology and Basics of Compaction\nEffect of Unit Weight\, Voids\, and Fabric/Structure\nField Compaction Procedures\nRelative Density and Relative Compaction\nPractical Issues and SAV&S Field Control Method\nChoice of Field Compaction Control Method\n\nSession 2 \n\nReview of classwork assignment\nRoadmap for Day 2\nShear Strength Characteristics of Compacted Soils\nVolume Change Characteristics of Compacted Soils\nPermeability Characteristics of Compacted Soils\nProof-rolling\nReview of full workshop\nInteractive Question and Answer (Q&A) session\n\nAdjourn
