Stiffness of cold asphalt mixtures with recycled aggregates from construction and demolition waste

Mechanical, durability and microstructure properties of Cold Asphalt Emulsion Mixtures with different types of filler

“…One of the most significant trends towards more eco-friendly asphalt mixes is the use of material such as recycled asphalt pavement, municipal solid waste incineration ash, construction and demolition waste material, cement kiln dust and coal ash [1][2][3][4][5][6][7][8].…”

Nonlinear elastic behavior of bitumen emulsion-stabilized materials with C&D waste aggregates

“…Hence, the peak stiffness was achieved with the minimum studied water content (9%). As discussed previously [20][21][22], lower contents of bitumen and water are not advisable when using CDWA, because their high absorption tends to bring about premature setting of the asphalt emulsion during the mixing process, forming clots and thereby obstructing the complete coating of the aggregates.…”

“…This research area has already been explored and a higher rate of success was achieved with other construction materials such as concrete [14][15][16] and HMA [17][18][19], and a study of mixtures with asphalt emulsion was also initiated [20][21][22].…”

“…Because the visco-elasto-plastic behavior of cured BSM-E with CDWA has already been studied [20][21][22], the aim of this study was to provide a preliminary understanding of their nonlinear elastic behavior. For this purpose, BSM-E before and after curing were treated as granular materials and studied using dynamic triaxial tests.…”

Behavior of a hot mix asphalt made with recycled concrete aggregate and crumb rubber

“…In comparison to other uses (e.g., base and subbase course materials, concrete), few studies have been performed in order to evaluate the potential use of RCA in asphalt mixtures (Berthelot et al 2010;Pérez et al 2012a;Moghadas et al 2013;Pasandín and Pérez, 2013; D r a f t Pérez et al 2007Pérez et al , 2010Pérez et al , 2012Pérez et al , 2012aBessa et al 2012;Lee et al 2012;Gómez-Meijide and Pérez, 2014;Gómez-Meijide et al 2015;Radević et al 2017;Al-Bayati et al 2018;Kareem et al 2018) and also higher air voids (Paranavithana and Mohajerani, 2006;Rafi et al 2011;Pérez et al 2012a;Pasandín and Pérez, 2014;Pourtahmasb and Karim, 2014;Fatemi and Imaninasab, 2016;Qasrawi and Asi, 2016;Zhang et al 2016;Pérez and Pasandin, 2017;Radević et al 2017;Al-Bayati et al 2018;Kareem et al 2018). It is also general agreement that both OAC and air voids increase with higher RCA contents and when it is used as fine or filler aggregate (Rafi and Qadir, 2011).…”
