Incorporation of coconut fiber into the asphalt coating layer of flexible pavements

Abstract

The challenge of designing a resistant floor, aims to conceive an engineering work that meets the structural and functional demands. Thus, this work aimed to incorporate coconut fiber into the asphalt coating layer to gain compressive strength and contribute to the reduction of coconut waste rates to the environment, since this material is characterized as lignocellulosic, as it consists of especially by cellulose, hemicellulose and lignin, which provide resistance to the structure of this material. In main results, the fiber presented around 28% of lignin, a component responsible for the resistance. From the granulometric and compression tests, it was observed that coconut fiber is found as a material applicable to the incorporation in asphalt mix for strength gain and reduction of production cost.
