Overview

This research demonstrates improved mechanical performance with graded asphalt dust in concrete paving blocks, suggesting better resource use.

Key Points

  • To assess the mechanical performance and sustainability of incorporating asphalt dust in alkali-activated concrete paving blocks.
  • Proposed a graded utilization strategy based on particle size of asphalt dust waste (ADW).
  • Fine ADW fraction replaced blast furnace slag, while coarser ADW replaced river sand.
  • Investigated different lithologies of ADW, namely limestone and basalt.
  • Compressive strength improved from 45.3 MPa to 56.6 MPa.
  • Water absorption decreased from 5.3% to 4.1%.
  • All mixtures met abrasion and slip resistance requirements for pedestrian pavement.
