Mechanically Stabilized Earth (MSE) walls are widely used in transportation projects due to their cost-saving, time-efficient, and resilient nature. Recently, American Association of State Highway Transportation Officials (AASHTO) and Federal Highway Administration have outlined new design changes to improve the service life of the walls in the FHWA Geotechnical Engineering Circular (GEC) 011. TRB will host a webinar on Wednesday, December 11, 2024 from 12:00 PM to 1:30 PM Eastern that will provide background and an overview of four design approaches for MSE walls: the coherent gravity method, the simplified method, the stiffness method, and the limit equilibrium method. Presenters will discuss how to select the appropriate parameters for the design of MSE walls based on geometry, facing, reinforcement, and backfill utilized.
This webinar is sponsored by TRB’s Standing Technical Committee on Transportation Earthworks.

Transit operators and other frontline workers often deal with high-stress situations, including fatalities, exposure to drug use, along with verbal and physical assaults. Such situations can take a serious toll on their mental health. These stressors contribute to difficulties in both hiring and retaining transit workers.  TRB will host a webinar on Thursday, December 12, 2024 from 1:00 PM to 2:30 PM Eastern that will explore the key stress factors affecting workers and offer actionable solutions for agencies to improve working conditions. Presenters will discuss how agencies can address the root causes of stress, develop effective mental health programs, and implement strategies to enhance morale and build trust among frontline employees.

This webinar is based on TCRP Report 245: Mental Health, Wellness, and Resilience for Transit System Workers.

This webinar is sponsored by TRB’s Transit Cooperative Research Program and the Standing Technical Committee on Truck and Bus Safety.

There is no fee to attend this webinar. Registration is required.

Tack coat specifications can promote long-term pavement performance and reduce issues like slippage and delamination between layers. TRB will host a webinar on Tuesday, December 17, 2024 from 1:00 PM to 2:30 PM Eastern that will provide an overview of NCHRP Web-Only Document 381: Developing Laboratory Methods and Specification Language to Test Tack Coat Materials, highlighting key findings from the study, including recommended changes to tack coat material specifications. Presenters will cover the evaluation plan for tack coat materials and a field experiment designed to validate the proposed specifications.
This webinar is sponsored by TRB’s National Cooperative Highway Research Program and the Standing Technical Committees on Production and Use of Asphalt Mixtures and Asphalt Pavement Construction and Rehabilitation.

The transportation sector is advancing towards full digital product delivery and digital as-built objectives within civil infrastructure. This transformation is driven by the goal of a fully end-to-end digital, asset-centric, interoperable data flow. However, current methodologies still rely on outdated concepts, such as 2D/1D plans and profile/cross-section sheets, which are disconnected from modern construction goals that demand the integration of open building information modeling (BIM) and digital twin technologies. To effectively achieve these goals, it's essential to address the existing geospatial and geodesic inconsistencies between real-world conditions and virtual 3D models. TRB will host a webinar on Wednesday, December 18, 2024 from 11:00 AM to 12:30 PM Eastern that will raise awareness within the department of transportation (DOT) community about the critical need to resolve ambiguities between virtual 3D models and real-world conditions.
This webinar is sponsored by TRB’s Standing Technical Committee on Geospatial Data Acquisition Technologies and the subcommittee on Geospatial and Geodetic Aspects of Building Informational Modeling.

Changes to truck operations and the associated loads will impact both existing and new flexible and rigid pavements, making them an important consideration for owner agencies. TRB will host a webinar on Thursday, December 19, 2024 from 12:00 PM to 1:30 PM Eastern that will facilitate proactive considerations to changes in pavement loading due to advancements in truck technology. These advancements impact current pavement design methods for durable and resilient pavements in the future. Presenters will share international initiatives on pavement technology strategies to address needs such as increased axle loads due to the weight of batteries and an increased loading frequency from truck platooning.
This webinar is the second of a two-part series that will explore potential advancements in truck technology such as electric trucks, truck platooning, CAVs, and their impacts on pavement performance, design methods, and maintenance. The first webinar, Anticipated Truck Loadings in Pavement Design—Part I, was held on November 25, 2024.
This webinar is sponsored by TRB’s Standing Technical Committees on Asphalt Pavement Design and Rehabilitation and Concrete Pavement Design and Rehabilitation and the Subcommittee on Truck Size & Weight.
Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100.
