Gravel road designs are at times overlooked or not understood. This presentation will review the criteria to consider for gravel roadway designs. Participants will be challenged to think about the roadway section, it’s function, water issues, gravel loss methods and generally how to make gravel roadways...

This webinar will give participants a look inside the state-of-the-art of using Intelligent Transportation Systems (ITS) to solve real world work zone traffic control and safety problems. The course will highlight resources available for you to use in considering, planning, designing, deploying, maintaining...

The presentation will cover research methods and results of the Mountain-Plains Consortium (MPC)-439 research project on this topic. The study conducted by SDSU was intended to resolve longitudinal joint deterioration of the double tee precast girder system commonly used in local government bridges of...

This webinar will present the research findings of the Mountain-Plains Consortium Research Project 480. This research was based on innovative geometric designs as a solution to the challenge of increased traffic volume with limited resources. This particular study focused on diverging diamond interchanges. The...

Many communities in the U.S. were not designed for pedestrian and bicycle travel. However, today, walkability and bikeability are important for active transportation and are indicators of a livable community. Accommodating pedestrians and bicyclists must be done safely. Each year, over 5,000 pedestrians...

While perpetual pavement (PP) concepts received heavy attention about 15 years ago, many states continue to apply the concepts to pavement design. Perpetual pavements are intended to last 50 years or more with treatments limited to the top 2 to 3 inches of pavement. To do this, designers specify materials...

Provide an overview of design for all types of deep foundations (driven pile, drilled shafts, micropiles and auger-cast piles), including typical sizes and capacities. Introduce the concept of support cost. Discuss construction of driven piles including hammer types, vibration mitigation, splicing...

Flowing water can have sufficient energy to cause substantial erosion. Scour produced by rivers and streams flowing under highway bridges can be detrimental to the integrity of bridges. This presentation will cover bridge scour mechanisms, analysis and repair methods or countermeasures. Topics to...
