TRB Webinar: Managing Gravel Road Maintenance
TRB conducted a webinar on April 10, 2012, that explored techniques for maintaining and managing granular surfaced roads. Participants must register in advance of the webinar, and there is a fee for non-TRB Sponsor employees. Contact Reggie Gillum at
RGillum@nas.edu to request a recording of the webinar.
Webinar presenters will share techniques for maintaining and managing granular surfaced roads focusing on proper materials, blading techniques, and preserving the granular material placed on the road. Discussion of base stabilization and dust palliative chemical use will also be included.
This webinar is designed to be beneficial for motorgrader operators, road supervisors, road managers, county and city engineers, and gravel producers and handlers.
