Question

If geotextiles are used as reinforcements, then they should have __________

(a) low modulus of deformation

(b) high modulus of deformation

(c) low coefficient of friction

(d) low breaking strength

I had been asked this question in an interview.

This intriguing question comes from Geotextiles in division Reinforced Earth and Geotextiles of Geotechnical Engineering II

Answer 1

Right option is (b) high modulus of deformation

To elaborate: When the geotextiles are used as reinforcements in the soil, they should take up some of the tensile stresses and help to distribute them more evenly. Therefore, they must have high modulus of deformation.
