Pullout Performance of Strip Reinforcements for MSE Walls

On by Geosynthetica
News and Articles

By John Sankey and Robert Lozano – For discrete reinforcing strips used in MSE walls, standards developed under the AASHTO codes have identified a method for evaluating pullout of ribbed steel reinforcements through conservative default values using a friction factor term identified as f*. A similar default basis for polymeric reinforcing strips is not available in AASHTO; only values meant ... »
