Self-healing capacity of asphalt mixtures with steel fiber, steel slag and graphite powder, evaluated with microwave induction and fatigue test
نویسندگان
چکیده
Self-healing in asphalt mixtures can be induced by adding particles that are susceptible to heating electromagnetic microwaves. This process allows the closure of microcracks caused fatigue phenomenon and extend service life pavement. In this article, self-healing index without with addition steel slag (15% 65.7%), fibers, (0.2% 0.4%), graphite powder 65.7%) was evaluated. The determined after subjecting damage, microwave heating, rest, damage again. Results showed all additions led healing capacity. A higher observed when mixture produced than powder. It found use a content fibers more effective for healing, successful must heated temperatures ranging between 50°C 75°C. results also it is possible achieve high values having subject heating.

Performance Improvement of Porous Asphalt Mixtures using Crumb Rubber and Steel Slag Powder
In recent decades, porous asphalt has been extended for surface drainage in various regions throughout the world. The permeability of porous asphalt has an important role in the performance of asphalt pavements in the rainy weather. The most remarkable problem related to the porous asphalt is its short service time. Considerable efforts have been made to enhance the mechanical properties of por...
متن کاملSteel Slag Utilization in Asphalt Mixes
Steel slags are the major byproduct from the conversion of iron to steel in the basic oxygen (major type), electric arc and open hearth (minor type) steelmaking processes. Steel recovery from the slag results in a processed aggregate with both positive (wear resistant, skid resistant, rough textured, angular, well graded, stripping resistant) and negative (heavy, expansive) features. Considerab...

This research was conducted in order to evaluate fatigue behavior of asphalt mixes containing Electric Arc Furnace (EAF) steel slag. After initial evaluation of the properties of EAF steel slag using X-ray Diffraction (XRD) and Scanning Electric Microscope (SEM), six sets of laboratory mixtures were prepared. Each set were treated replacing various portions of limestone aggregates of the mix wi...

The present paper deals with the design of experimental work matrices for two groups of experiments by using Response surface methodology (RSM). The first EDM group was dealt with the use of kerosene dielectric alone, while the second was treated by adding the graphite micro powders mixing to dielectric fluid (PMEDM). The total heat flux generated and fatigue lives after EDM and PMEDM models we...
