“…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). Besides, asphalt mixtures using RCA, generally meet the national Marshall design specifications for medium and low traffic (Pérez et al 2007(Pérez et al , 2012Mills-Beale and You, 2010;Qasrawi and Asi, 2016). Additionally, the grain size distribution of asphalt mixtures changes during the mixing and compaction process, mainly because of the weakness of the attached mortar on the RCA surface (Paranavithana and Mohajerani, 2006;Cho et al 2011;Arabani and Azarhoosh, 2012;Pasandín and Pérez, 2013).…”

“…Most studies agree that asphalt mixtures containing RCA had a considerably higher stripping potential, especially when increasing its content (Paranavithana and Mohajerani, 2006;Mills-Beale and You, 2010;Pérez et al 2007Pérez et al , 2010Pérez et al , 2012Pérez et al , 2012aZulkati et al 2013;Qasrawi and Asi, 2016;Ossa et al 2016;Pasandin, 2015, 2017). However, some studies reported that mixtures using RCA meet the national specifications for resistance to moisture damage (Aljassar and Al-Fadala, 2005;Shen and Du, 2005;Cho et al 2011;Chen et al 2011;Zhu et al 2012;Pasandín and Pérez, 2013;Wu et al 2013;Gómez-Meijide and Pérez, 2014).…”

“…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).

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

An experimental program was devised to evaluate the effect on the resistance of a hot mix asphalt (HMA), due to the total replacement of a natural aggregate (limestone -LS) by a recycled concrete aggregate (RCA). Two asphalt binders were used: conventional AC 50-70 (penetration grade) and AC 50-70 modified with crumb rubber (CRM). The mechanical properties investigated were the stability and flow ratio (Marshall test), indirect tensile strength, resistance to abrasion (Cantabro test), resilient modulus, resistance to permanent deformation, to fatigue and to moisture damage (modified Lottman test). When the LS is completely replaced by RCA, the resistance under monotonic loading, moisture damage and permanent deformation improved, the mass loss in the Cantabro test and the resilient modulus

“…Qasrawi and Asi (2016) indicate that mixtures containing RCA appear less sensitive to water (stripping resistance) than RCA-free mixes and that the replacement rate of more than 50% of the RCA does not violate 80% of the TSR limit [19].…”

The distress of moisture induced damage in flexible pavement received tremendous attention over the past decades. The harmful effects of this distress expand the deterioration of other known distresses such as rutting and fatigue cracking. This paper focused on the efficiency of using the waste material of demolished concrete to prepare asphalt mixtures that can withstand the effect of moisture in the pavement. For this purpose, different percentages of waste demolished concrete (0, 10, 20, 30, 50, 70 and 100) were embedded as a replacement for coarse aggregate to construct the base course. The optimum asphalt contents were determined depending on the Marshall method. Then after, two parameters were founded to evaluate the moisture susceptibility, namely: the tensile strength ratio (TSR) and the index of retained strength (IRS). To achieve this, the indirect tensile strength test and the compressive test were performed on different fabricated specimens. The results show that mixtures with a higher percentage of demolished concrete possess higher optimum asphalt content as this parameter increased from 3.9 % for control mixture to 4.5 % for mixture with coarse aggregate that fully replaced by demolished concrete. This work indicated that optimum percent of waste demolished concrete that can be utilized in the asphalt mixtures is 30 %, whereas this percent recorded higher value of increased increments for TSR and IRS by 10.6 % and 7.9 % respectively.

“…Percentages up to 40% of RCA will be suitable only when using anti-stripping additives. Qasrawi and Asi (2016) indicate that RCA replacement up to 50% leads to mixtures that comply with water resistance requirements. Nevertheless, these authors also stated that RCA leads to mixtures with lower stripping resistance.…”

To guarantee sustainable construction, we investigated the reuse of construction and demolition waste (CDW) as recycled concrete aggregate (RCA) for the manufacture of hot-mix asphalt (HMA) in place of natural aggregates. The use of waste tire rubber as a bitumen modifier could be a means of improving the water resistance of these mixtures. In this investigation, moisture damage resistance of HMA for binder course, type AC 22 bin S, was analysed. Percentages of 0% (control mixture), 35% and 42% RCA were used in place of natural aggregates. Two types of bitumen have also been used: a conventional B35/50 penetration grade bitumen and BC35/50, a crumb rubber modified bitumen. Volumetric properties and water resistance were determined by means of indirect tensile tests. The results indicate that contrary to expectations, mixtures made with BC35/50 do not display better water resistance than mixtures made with B35/50. Nevertheless, a mixture made with B35/50 or BC35/50 does comply with Spanish requirements. Additionally, reversibility of moisture damage resistance was clearly demonstrated in this research. This research may help to better understand the performance of HMA made with RCA and the drawbacks of using waste tire rubber as a bitumen modifier.
