Sugarcane bagasse as an alternative material for the reuse of scarified pavement material

The increasing amount of sugarcane fibrous waste presents range of challenges such as pollution and land degradation through uncontrolled disposal which are menaces to the environments. The reconstruction of existing highways due to modern globalization results in a larger volume of scarified pavement materials that are often discarded as waste which upon reused as constituent of road sub layers may result in promising result. Also finding an economical and sustainable approach of recycling and reusing of reclaimed scarified- pavement materials in place of conventional laterite soil for road construction could potentially unlock a new dimension. Thus, this study attempts to evaluate the geotechnical characteristics of reclaimed pavement materials stabilized with sugarcane bagasse ash (SCBA) for road sub layers application. The preliminary results show that sugarcane bagasse ash can potentially improve the reclaimed soil’s strength characteristics, with an increased proportion of sugarcane bagasse ash, Unconfined Compressive Strength (UCS), and California Bearing Ratio (CBR) were enhanced by more than 350% and 100% respectively. All the geotechnical characteristics analyzed were found to be enhanced significantly by increasing the amount of sugarcane bagasse ash up to. This makes the SCBA-stabilized reclaimed soil a potential suitor in relaying and repair works of pavements sublayers.
