Soil nailing technology is very 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 is intricately linked with its construction procedures. To avoid adverse performance issues, design and construction processes for a soil nail wall must be tailored […]
This is a pilot Instructor Led Training (ILT) course for the Federal Highway Administration (FHWA). It will be offered as a 2-day course in Salem, Oregon. Naresh Samtani will be the co-Lead Instructor with Jerry DiMaggio of ARA.
Mechanically Stabilized Earth (MSE) walls are used extensively for grade-separation fill structures in many applications, e.g., highways, railways, marine, commercial, etc. To avoid adverse performance issues, and to ensure safe and serviceable MSE walls, the fills and component details must be tailored to specific geometry and the environment (conditions) expected over its specified lifetime. To […]

This 2-day workshop will discuss compaction of soils and engineering properties of compacted soils. Using 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.

This presentation will be made for the Arizona Chapter of American Public Works Association (APWA) at its May 2022 monthly meeting. The presentation will introduce three recent developments in geotechnical engineering that provide significant value to transportation infrastructure projects. These include: (1) Infiltration evaluation for deep foundations in ephemeral streams (2) Evaluation of subgrade stresses […]
Using a collaborative and interactive learning approach, this virtual workshop will help you understand: (a) the design and construction procedures for drilled shafts in soils, and (b) the importance of constructability considerations in design of drilled shafts. The workshop will help you assimilate these crucial considerations through active participation by frequent interactions throughout the workshop and real-time expert feedback. The interactions will facilitate a better understanding of the nuances of the various design and construction procedures which would help you avoid costly design and construction errors in real-world projects. In between the two live sessions, attendees will independently work on an application (e.g., exercises) or a reflection (e.g., reading) assignment.

Foundations for bridges and approach structures should be designed so that their movements will not damage the bridge superstructure and associated structures such as abutments and approach slabs. Various aspects of movements that should be considered in the design of bridges include (a) the effect of uneven (differential) settlement between various support elements, (b) the rotation and horizontal movements of the foundation system affecting movements at the bridge-seat level; (c) movements due to material deterioration; and (d) serviceability problems near a bridge abutment and approaches. The presentation will be based on latest (2020) version of the Bridge Design Specifications (BDS) and the Load and Resistance Factor Design (LRFD) platform of the American Association of State Highway and Transportation Officials which is a key component of Federal Highway Administration (FHWA) guidelines for this topic. Information on Extended Service Life (ESL) and Protection Index (PI) concepts from AASHTO’s latest (2020) Guide Specification for Service life design will also be presented.
