Maintenance and other field workers are exposed to hazards that require a higher level of management than traditional office-based positions within state departments of transportation (DOTs). This webinar will explore the national state of practice and trends on the use of safety management systems to manage maintenance worker safety.
Utilities can cause delays to transportation projects. Proper and timely implementation of subsurface utility engineering (SUE) can assist in reducing those delays. This webinar will explore state department of transportation (DOT) practices for SUE and highlight findings from a recent TRB NCHRP synthesis study.
Modern health, environmental, and social disruptions require transportation institutions to develop new skill sets for teams and preparations for extreme scenarios. This webinar will share approaches to equip teams with new skill sets in decision-making and preparing for modern crisis scenarios.
The light-weight deflectometer (LWD) has seen increased use in quality control and quality assurance testing. Pavement applications include general assessment of unbound layer stiffness and controlling the quality of compacted aggregate and soil layers. This webinar will share test set up, data analysis, and limitations of the LWD device.
Stabilization additives are used to increase the strength and stiffness of road foundations in weak and susceptible soils. Numerous additives exist for improving performance of aggregate base and subgrade layers. This webinar will explore examples and case studies using conventional and nonconventional additives.
The most common approach to reducing highway noise traffic is noise barriers. This webinar will explore the many alternatives that state departments of transportation can consider that may be more context- and cost-appropriate.
