TL;DR: In this paper, a life cycle assessment to compare an RCA-based portland cement concrete (RCA-PCC) pavement and a plain PCC pavement (i.e., without RCA) from all three aspects of sustainability (e.g., economic impact, social impact, and environmental impact) was carried out using an economic input-output life cycle assess (EIO-LCA) approach.

TL;DR: In this article, the authors present a life cycle inventory analysis of reclaimed asphalt pavement (RAP) in portland cement concrete (PCC) as an aggregate replacement for pavement applications.

TL;DR: In this paper, the effect of steel fiber reinforced concrete (SFRC) mixtures under both uniaxial compression and tension was investigated and it was statistically evident that the tensile strength and the strain at the peak load under either compression or tension are positively correlated with the fiber reinforcing index (RI), while there is no sufficient evidence indicating that the modulus of elasticity and compressive strength can be correlated with RI.

TL;DR: In this paper, the authors investigated whether partial replacement of virgin coarse aggregate by coarse RAP is a practically viable option to formulate PCC paving mixtures, and they showed that replacing virgin coarse aggregates by RAP with sufficient intermediate size particles offers the benefits of achieving dense combined aggregate gradation.
