Pervious pavements made up of porous concrete are increasingly utilised as a climate adaptation tool to manage stormwater runoff, replenish groundwater, and mitigate urban heat island effects. However, the widespread use of porous concrete is often limited by its stiff, low-slump consistency, which also hinders uniform field placement. Moreover, the absence of standardised workability criteria leaves the quality of compaction dependent on subjective judgment. While slipform paving offers a suitable method for mechanised, consistent placement, the substantial compaction energy it delivers exceeds the conditions under which existing workability frameworks were developed. The combined effect of aggregate angularity and paste volume on the compaction and strength properties of porous concrete under heavy mechanised placement has not previously been quantified in a volumetrically controlled framework.
