Statistical Approach Model to Evaluate Permanent Deformation of Steel Fiber Modified Asphalt Mixtures

A good asphalt mixture is very important to maintain the triangle of sustainability. Many accidents occur due pavement damage such as permanent deformation caused by external loads induced heavy traffic. Stone Mastic Asphalt (SMA) has a low resistance moisture and other performances. researchers have conducted on SMA using various types fiber. However, not much research been done steel fiber in analyzed result obtained statistical approach. The objective this was identify optimum amount modified characterize performance approach Response Surface Methodology (RSM) Design Expert Software. In study, proportions 0 percent, 0.3 0.5 0.7 percent total weight were used. Marshall stability flow test, dynamic creep susceptibility ultimately, RSM analysis used evaluate properties fiber-modified SMA, which contained 6.2 PEN 60/70 binder content. testing findings unmistakably demonstrated that addition greatly improves mixture’s deformation. An found be most content from optimization Methodology, thus proven with additional enhancing mixture. As result, it can determined mixtures improved construction pavements, method an efficient for producing appropriate empirical model relating parameters predicting best asphaltic
