A fixed number of geosynthetics will be checked by defined European as well as the Swiss test methods. The test results will be evaluated and correlations will be determined. From the evaluations and correlations suggestions on test methods and standards for geosynthetics with protection function will be formulated. The final report can be already used for the revision of the SN 670 243.
Corresponding to the request for proposal 40 geosynthetics with the defined 10 test methods will be checked. The 40 geosynthetics will be purchased on the European and the Swiss market. The tests on the geosynthetics will be done in European and Swiss accreditated testing institutes. The test results will be evaluated and correlations will be defined. From the evalutation suggestions for test methods and standards will be developed.
The suggestions will be used as a base for the revision of the norms SN 670 243 and SIA 272 in regards to geosynthetics with protection function.
