Abstract

The current work tries to valorize the bottom ash from Municipal Solid Waste Incineration (MSWI). The bottom ash from waste incineration consists of atypical granular materials. They are industrial by-products resulting from the incineration of domestic waste and the way of the considered valorization is road gravel. In this paper, we present the state parameters of bottom ash taken from a recycling company in the North of France. These features can help us evaluate our bottom ash according to the technical guide of realization of embankments and subgrades.

Highlights

  • Municipal solid waste management technologies include landfilling, recycling/recovery, and incineration

  • THE MATERIAL The Municipal Solid Waste Incineration (MSWI) bottom ash used in this study originated from the platform of recycling of the PréFerNord Company located in Fretin, France

  • The obtained values of compaction characteristics of bottom ash fall within the variability of the field defined by information note of SETRA on the use of bottom ash in road construction

Summary

A Study of State Parameters for Road Construction of MSWI Bottom Ash

Abstract-The current work tries to valorize the bottom ash from Municipal Solid Waste Incineration (MSWI). The bottom ash from waste incineration consists of atypical granular materials They are industrial by-products resulting from the incineration of domestic waste and the way of the considered valorization is road gravel. We present the state parameters of bottom ash taken from a recycling company in the North of France. These features can help us evaluate our bottom ash according to the technical guide of realization of embankments and subgrades. This article presents the state parameters by particle size distribution, moisture content, absolute density, Proctor compaction and bearing capacity index tests These tests results are evaluated according to the technical guide of realization of embankments and subgrades
