Life cycle assessment of asphalt pavement containing MSWI bottom ash
Abstract This paper employs the life cycle assessment method to evaluate the energy consumption and environmental emissions associated with the use of municipal solid waste incinerator (MSWI) bottom ash aggregate (BAA) in asphalt pavement. The analysis divides the life cycle into four stages: the ra...

| description | Abstract This paper employs the life cycle assessment method to evaluate the energy consumption and environmental emissions associated with the use of municipal solid waste incinerator (MSWI) bottom ash aggregate (BAA) in asphalt pavement. The analysis divides the life cycle into four stages: the raw material production stage, the pavement construction stage, the operation maintenance stage, and the structural demolition stage. Energy consumption is calculated using the quota method, while environmental emissions are calculated using an emission factor method. Based on an analysis of life cycle inventory data, asphalt pavement containing MSWI BAA shows 9.9% higher energy consumption than conventional asphalt pavement, while both have similar gas emissions throughout their life cycles. Considering the significant consumption of domestic waste incineration bottom ash in asphalt pavement containing MSWI BAA, these advantages are believed to outweigh the disadvantages. This research provides relevant data for the application of bottom ash in asphalt pavement engineering, promoting its development and implementation. |
