M/s Reinforced Earth India is involved in various highway projects in India using polymeric strap as soil reinforcement for design of mechanically stabilized earth (MSE) retaining walls. There are several design guidelines in practice for design of MSE structures in India like British Standard, Federal Highway Administration Publication, NCMA and French Standard AFNOR and now very recently published local Indian guideline IRC SP 102–2014. However, there is no significant reference available on pull-out coefficient to be considered for design of MSE structures except in FHWA for steel reinforcement and AFNOR. Most of these standards and guidelines are based on specific knowledge and many experimental results carried out in France, UK, and USA. Nevertheless, there remains some concern that these guidelines are not fully comprehensive for Indian soil conditions and construction practices. The authors have already published a paper on pull-out test conducted in India for High Adherence steel strip reinforcement. This paper is going to present the results of various field and laboratory pull out tests conducted on polymeric strap soil reinforcement. The results were also used to validate the apparent co efficient of friction μ*, used in the design. The tests were conducted in many projects with different fill properties and heights to study the behaviour of the interaction of soil-reinforcement with the fill. This article also depicts the methodology, equipment and tools used, measurement of test data and findings.
