Abstract

In order to solve the problem of excess steel slag resources and shortage of natural aggregates required for traditional highway construction, several studies have verified the feasibility of using steel slag as pavement aggregate, and related test sections have been laid, which shows that the performance of steel slag pavement is good. This study applies the Life Cycle Assessment (LCA) theory to analyze an engineering case, establishing a carbon emission accounting model and calculating emission reductions achieved by substituting traditional natural sand and gravel with steel slag in highway reconstruction and expansion projects. The carbon mitigation potential of this substitution was further evaluated.
