Fibras del raquis del banano como componente del concreto asfáltico para mejorar sus propiedades mecánicas.

Abstract

With this research work, it was observed in different tests, the increase of the resistance to the deformation of the mixtures and the reduction of the presence of cracks; In addition, the new conditions of service and maintenance were analyzed. Likewise, the use of banana rachis fiber in asphalt concrete was studied, by dosing it in 0.0%, 0.3% and 0.5% mixed wetly and with an asphalt cement content of 6%, to determine the optimal percentage dose of banana rachis fibers, which should be used in the asphalt mixture with respect to the weight of aggregates and thus, the best possible mechanical behaviour is produced. In addition, it was determined that by introducing asphalt cement to the banana rachis fiber in a proportion of 320% of the weight at 120 ºC, there is a reinforcement in the internal structure, which helps the resistance to bending; In the same way, a social proposal for environmental preservation with technological and economic innovation was established, based on the use of abundant agricultural waste, which can benefit families in rural areas.
