AASHTO Drop Wall Requirements
- Do you have any thoughts as to a way to note correct type of end section used for skewed box installations?
- Any recommendations as to slab details for fill heights less than 1 foot?
- Any ideas to clean up and ensure that a slab included on a proposed plan, covered by pay items or incidental to structure, is designed as required?
- Can a geotextile filter be used in lieu of the 6-12 inches of granular filter that we commonly call for under the riprap?
- I'm working on a project where we're looking at using a prestressed girder bridge; however, it's in a flood storage area, which submerges the bridge during the 100-year flood. I'm looking for guidance on using blow holes in the top of the deck to allow the air between the girders to escape, which will alleviate buoyancy and girder lateral loading problems. What do you think?
