Abstract
Permanent deformation, often known as rutting, happens as a result of repeated loading from
high traffic, which causes gradual buildup of permanent deformation under repeating tyre pressures. In
engineering practise, asphalt mixtures are blended with steel fibres to enhance traditional asphalt concrete pavement performance, decrease road maintenance costs, and extend the life of the pavement. To replicate the performance of flexible pavement with life, two slabs with dimensions (300*300*50) mm were produced for rutting tests with two percentages of steel fibre content (0.0, 0.2) percent. The findings revealed that the rutting value in the control mix is (27.04) mm, but the rutting value at 0.2 percent steel fibre content and 5.5 percent asphalt content is (22.42) mm. At 0.2 percent steel fibre concentration, the dynamic stability of the asphalt mixture increases by around 6.4 percent. The development of a three-dimensional finite element model for flexible pavements is carried out using ABAQUS (6.14-4) to mimic laboratory testing. A statistical analysis is used to determine the compatibility of lab models and numerical models, as well as to evaluate the possibilities of employing the numerical technique to anticipate further improvements in the pavement body.
