The use of waste wool and petroleum products as a filler for geogrids in the structural layers of the road surface (review)

Abstract

This review article explores the use of agricultural unused sheep wool and petroleum byproducts spilled on the soil to improve the structure of road surfaces. Tiles obtained by saturating a filler made from animal hair, such as sheep's wool, with oil pollutants can be used as a road surface. Since not all types of sheep wool are used, attention is paid to unused types of wool and methods of processing them. Furthermore, the proposed work contributes to the resolution of an environmental problem. Tiles saturated with oil pollutants are laid on geogrids prepared for the road surface. The geometric dimensions of the geogrid are selected depending on the climatic conditions of the region and the condition of the road surface. The proposed method of laying road surfaces improves the quality of roads and reduces construction costs. Moreover, an increase in the service life of the road is achieved through the use of tiles impregnated with residual oil, which does not absorb moisture and does not allow it to penetrate into the road pavement. This results in the prevention of cracking in the road during the winter season.
