Self-repairing asphalt mixing design by heat induction, to control surface faults of heavy traffic in tropical areas of South America

This research proposes the design of an asphalt mixture that has the property of self-repair, taking as a starting point the design of the conventional asphalt mixture, which incorporates 1 % of polymers and fibers of steel wool, with 1 %, 2 % and 3 % to improve the physical and mechanical behavior of the asphalt mixture and thus find the repair of cracks by heat induction, for this the three-point bending test is performed on the repaired samples to determine the percentage of recovery. The results obtained indicate that, in general, the repair of asphalt mixtures was 50.7% with respect to their initial resistance. In addition, it is observed that metallic aggregates increase the levels of repair of the mixtures and increase the stability in reference to a conventional mixture, being better the results obtained with the asphalt mixture with a lower percentage of steel wool fiber (1 %). If test sections are carried out and this technique is put into practice to see its viability, it is concluded that this technique will provide great potential in pavement maintenance.
