Discussion of "Fiber-reinforced flyash subbases in rural roads," by Praveen Kumar and Shailendra Pratap Singh

Abstract

[Extract] The discussers appreciate the authors for presenting test values of many properties of fiber-reinforced fly ash by conducting more than 500 tests. These properties are listed as: optimum moisture content OMC, maximum dry density dmax, unconfined compression strength UCS, stress-strain properties, modulus of elasticity E, California bearing ratio CBR, resilient modulus Mr, and modulus of subgrade reaction. These values can be useful for dealing with pavement design works involving fiber-reinforced fly ash. Based on the test values, the authors have emphasized that the fiber-reinforced fly ash is suitable in an economical way for subbase courses in rural roads.
