ESR8. Waste mineral filler Recycling in new Pavement solutions (WasteRP)

Objectives:

To reduce the impact of paving materials by means of new mix designs for warm bituminous mixtures and draining paving blocks (cement bound or alkali-activated) with industrial wastes e.g. from quarries and mines.

• Task 8.1: full physical-geometrical characterization of industrial waste fillers from quarrying/mining activities.
• Task 8.2: mix-design of warm mix bituminous mixtures for Split-Mastic-Asphalt (SMA) wearing courses & Porous Asphalts.
• Task 8.3: mastics and mortars rheology by means of Dynamic Shear Rheometers (DSR) and Dynamic Mechanical Analysers.
• Task 8.4: alkali-activation of waste precursors to create engineered binding pastes, artificial aggregates and paving blocks.

Expected Results:

• Recycling protocols (End-of-Waste) for industrial waste fillers into bitumen bound and cement bound mixtures.
• SMA and Porous Asphalts mix-designs for acoustic and pervious pavements’ layers.
• Cement bound and alkali-activation materials for binding pastes, paving blocks and artificial engineered aggregates.
