英文摘要: Abstract(#br)The objective of the paper is to assess the feasibility of using solid waste incineration (MSWI) bottom ash (BA) as cement-stabilized macadam (CSM) aggregate. CSM was prepared by replacing natural limestone aggregate with MSWI BA in different proportions (0%, 5%, 10%, 20%, and 30%). The physical properties, chemical properties, and micro-morphology of MSWI BA were studied to explore the mechanism of MSWI BA aggregate in CSM. The mechanical properties (unconfined compressive strength, cleavage strength, compressive resilience modulus), drying shrinkage, freezing resistance, and leaching behavior of CSM were tested. The results showed that MSWI BA had low density, low strength, high water absorption, high porosity, hydraulicity, and cementitious activity. Substitution of MSWI...
