Measurement of particle agglomeration and aggregate breakdown of reclaimed asphalt pavement
TL;DR: In this paper, the effect of milling speed on the RAP particle agglomeration rate was evaluated through a pavement maintenance project and the size-susceptibility of the aggloomate d particles, gradation deviation of the recycled mixture, and morphology classification of RAP particles were discussed.
Journal ArticleDOI
Ecological geopolymer produced with a ternary system of red mud, glass waste, and Portland cement
TL;DR: In this paper , the use of residues from the processing of bauxite and glass powder as precursors for the preparation of geopolymers was evaluated using compressive strength tests.
Journal ArticleDOI
Rethinking the carbon dioxide emissions of road sector: Integrating advanced vehicle technologies and construction supply chains mitigation options under decarbonization plans
TL;DR: In this article, the authors evaluated the impact of the combination of these two aspects on CO2 emissions mitigation of road life cycle is less known even though it is critical to the longer-term road transportation decarbonization and long-range policy making for transportation sector, especially under latest worldwide net-zero carbon emission goal.

Magnesium industry waste and red mud to eco-friendly ternary binder: Producing more sustainable cementitious materials
Maysa Lorena Figueiredo Martins,Paulo Roberto Ribeiro Soares Junior,Thiago Henrique da Silva,Priscila de Souza Maciel,Ivete Peixoto Pinheiro,Augusto Cesar da Silva Bezerra +5 more
TL;DR: In this paper, the feasibility of using industrial waste (i.e., magnesium industry waste (MW) and red mud (RM) as supplementary cementitious materials was evaluated, and a PC/MW/RM mixture containing 75% PC substituted with 25% of MW and RM was developed as a ternary binder.

Paulo H. R. Borges,Paulo H. R. Borges,Nemkumar Banthia,Himad A. Alcamand,Wander L. Vasconcelos,Eduardo Nunes +5 more
TL;DR: In this paper, the effect of silicate content on the mechanical and durability-related properties of metakaolin (MK) and BFS (blastfurnace slag) alkaline activated mortars was studied.
Journal ArticleDOI
Performance of Warm Mix Recycled Asphalt containing up to 100% RAP
TL;DR: In this article, the authors presented a study that combines Warm Mix Asphalt with the use of RAP aggregates, while being produced at lower temperature than traditional Hot Mixtures contain 100% RAP.

Bonding in cementitious materials with asphalt-coated particles: Part I – The interfacial transition zone
TL;DR: In this article, the authors quantified and compared the interfacial transition zone (ITZ) for mortar with RAP aggregates relative to dolomite aggregates through image analysis of backscattered electron micrographs.
Journal ArticleDOI
Durability and long term performance of geopolymer stabilized reclaimed asphalt pavement base courses
TL;DR: In this paper, a fly ash is activated in an alkali environment to form a geopolymer by triggering the unreacted polymeric compounds present in the fly ash, which is used to stabilize the RAP:VA mixes.
