Effect of Different Ingredients of Ultra High Performance Asphalt Concrete Pavement on Modulus of Elasticity Using Response Surface Modelling

Abstract

This paper provides the result of experimental and statistical modeling study on modulus of elasticity of Ultra High Performance Asphalt Concrete Pavement consisting different level of silica fume, superplastisizer, steel fiber, cement, and water binder ratio. Number of experiments designed by using design of experiment (DOE) in two levels, results modeled by using analysis of variance (ANOVA), and monitored using response surface methodology. This study clearly revealed the effect of each variable and their interactions on modulus of elasticity of Ultra High Performance Asphalt Concrete Pavement. This study is valid for the mixes of UHPC with 0.18–0.32 water binder ratio, 0.04–0.08 steel fibre, 0.7–1.3 cement, 0.15–0.30 silica fume, and 0.04–0.08 superplasticiser by aggregate mass.
