Feasibility Study of Reclaimed Asphalt Pavements (RAP) as Recycled Aggregates Used in Rigid Pavement Construction
TL;DR: In this paper , the sequential characterization of RAP aggregate to obtain optimized proportions for strength was carried out and the results showed that 40% RAP recycled aggregates with 10% ZSF as a replacement for cement outperform DRAP aggregates in concrete mixes.

Assessment of reclaimed asphalt pavement (RAP) as recycled aggregate for concrete
TL;DR: In this paper , a study about the performances of reclaimed asphalt pavement (RAP) sourced from five different Italian collection sites is presented to evaluate RAP as aggregate for concrete, and several RAP properties are investigated: physical properties (particles size distribution, water absorption, porosity, wettability), microstructure by microscopy, dimensional stability, and durability assessment by freezing-thawing cycles.

Evaluation of Mechanical Properties of Rigid Pavement with High RAP Content
TL;DR: In this paper , Zirconia silica fume (ZSF) is used as an admixture that partially replaced the ordinary Portland cement (OPC) in the concrete mix.

The Interfacial Transition Zone (ITZ) Between Cement Paste and Aggregate in Concrete
TL;DR: In this article, the authors describe the so called interfacial transition zone (ITZ) in concrete as the region of the cement paste around the aggregate particles, which is perturbed by the presence of the aggregate, and show that the higher porosity present initially is significantly diminished by the migration of ions during hydration.

Backscattered electron imaging of cementitious microstructures: Understanding and quantification
TL;DR: In this article, the general microstructural features of hydrated cement pastes are described and the possibilities to quantify backscattered electron imaging images of polished surfaces are described. And an example of the potential for BSE images to study concrete durability is given.
