Use of paper mill waste product for construction of internal roads and stockyard – a case study

This paper presents a case study about using industrial waste products such as paper mill fly ash and paper mill bed ash for construction of internal roads and stockyard of paper mill. The industrial waste products used were Paper Mill Bed Ash and Paper Mill Fly Ash. A detailed mix design study was carried out to determine optimum combination of the waste products, soil from factory premises and admixtures such as lime and cement. The optimum combination was determined to achieve maximum strength by keeping the admixtures to minimum. Based on the mix proportion determined in the lab a field trial was carried out to understand construction related issues. The feedback from field trial was used to further refine the design mix. The construction of both internal roads and stockyard were carried out with design mix. The performance of the road was monitored over the last two years and found to be satisfactory. This paper presents the details of the laboratory study to arrive at the design mix, field trials and construction of the roads and stockyard.
