Product specification

News, Q&A: GMA Techline | June 1, 2007 | By:

Subject: Product specification We are proposing to stabilize a section of eroded riverbank with riprap. We would like to install a fabric beneath the riprap to hold the existing sandy soils in place.

Can you give us a recommendation?

The river is tidal and the area is exposed to full sun so UV is a factor to consider.

Reply: Your question is a common one that has had quite a bit of past research, to the point that AASHTO has a generic specification for this particular application.

The spec is embodied in AASHTO M288-05, and I will fax the appropriate info to you today.

Thanks for asking.
