Abstract

The elasticity or resilient modulus of pavement materials is a very important material property in any mechanistically based design for flexible pavement. The resilient modulus test simulates the conditions in the pavement due to application moving wheel loadings. As a result, the test provides an excellent means for comparing the behavior of pavement construction materials under a variety of conditions including grading and bitumen content. Resilient modulus values can be used with structural response analysis models to calculate the pavement structural response to wheel loads and with pavement design procedures to design pavement structure. The key aim of this study is to identify the effect of state factor in term of grading, temperature and bitumen content on resilient modulus of bituminous mixture. Secondly, KenLayer software was used to indicate the pavement lifetime and proven the MR results from first objective. Various laboratory tests were conducted; Penetration test, Softening point test, Specific Gravity, Marshall Test and Resilient Modulus Test. From the outcome, clearly shows that more course aggregate will get higher MR and more bitumen content will lessen the MR value. Hopefully this outcome will contribute some valuable information in highway materials and continuations with other state factors are welcome from highway researchers outside to the new discovery of design pavement.
