“…The reference material in their publication included PG 64-22 asphalts of several crude sources. The viscosity increased in case of pure virgin asphalt [38], binder crumb rubber modifier (CRM), and rubberized warm asphalt binders after artificial short-term aging with rolling thin film oven (RTFO) [39,40].…”

Among warm mix asphalt (WMA) technologies, asphalt foaming techniques offer high potential in terms of decreasing production temperature. Reluctance of manufacturers to introduce this technology is connected with the concerns of a large investment costs. However, there are known additives which, through asphalt foaming, allow a decrease in temperatures by approximately 30 • C; the use of these additives do not involve expensive investment in order to change the asphalt mix production method. These additives are zeolites, that is, minerals of the aluminosilicate group, the crystalline structure of which contains water bound in a specific way. Its release, at mix asphalt production temperatures, causes asphalt foaming. It is currently known that zeolites can be used in WMA, including natural and synthetic zeolites obtained using chemical reagents and waste. This review presents the results of studies of WMA technology, including the effects of zeolite addition on asphalt properties and mix asphalt, as well as related environmental, economic, and technological benefits.

“…Also, the polymer cross-link density would be reduced as severe temperature could cause breaking of the cross-linking network of polymer corresponded to a gradual reduction in the modification level (Abdelrahman 2006). Limited studies have considered applying warm-mix technology additives (WMA) to the RTR-MBs in order to lower the mixing and compaction temperatures and allow better workability and handling , Akisetty et al 2011, Rodríguez-Alloza et al 2013). On the other hand, fewer studies have considered using devulcanised rubber by the cleavage of cross-linking sulphur bonds in rubber vulcanizates without cleavage of the polymer chain bonds, this resulted in improving the dispersion and interfacial adhesion of RTR and binder (Dong et al, 2011;Liang, 1999;Liang & Woodhams, 1998;Xiao-qing et al, 2009).…”

“…Also, the RTR-MBs cannot be stored for long periods after production because of the lack of compatibility between RTR and binder that leads to a phase separation problem. Many studies have been conducted to produce RTR-MBs that have reduced HTV and/or extended shelf life characteristics (Zanzotto and Kennepohl 1996, Glover et al 2000, Attia and Abdelrahman 2009, Akisetty et al 2011, Rodríguez-Alloza et al 2013. Some researchers utilized much severer curing conditions and fine rubber particles to overcome or alleviate these problems (Zanzotto and Kennepohl 1996, Glover et al 2000, Attia and Abdelrahman 2009).…”

“…Process of producing of hot mix asphalt (HMA) involves considerable fuel and energy consumption and emission of greenhouse gases, especially carbon dioxide. Warm mix asphalt (WMA) technology has been developed to solve the mentioned concerns and to produce, place, and compact bituminous materials at lower temperatures than HMA without sacrificing the quality of the resulting pavement [1][2][3][4][5][6][7][8]. Many researchers have indicated the advantages of WMA which are briefly summarized [3,4,8,9] as follows: lowering plant emission and fumes, reducing energy consumption and saving costs, improving workability and compaction efficiency, and quickening turnover to traffic due to reduced cooling time.…”

In traditional method of hot mix asphalt (HMA) production, large energy consumption and increased environmental awareness have resulted in the innovation of a production technology named warm mix asphalt (WMA). In this technology, various methods are used to reduce the temperature of production and paving. On the other hand, steel slag is the by-product of iron and steel factories, and many researches have been done around the world to use these materials in several fields, such as HMA industry. Various studies show steel slag to be considerably effective in improving the performance of asphalt concrete. One of the properties of steel slag is having high heat capacity value which leads to higher energy consumption during the production of HMA compared to conventional aggregates. The main aim of this study is therefore using WMA technology to reduce the energy consumption and to produce steel slag warm mix asphalt (SSWMA). In order to fabricate SSWMA in lab, an amino-based resin was used as an additive to decrease the viscosity of the bitumen. The amount of resin was ranged from 5 to 15 % by the weight of bitumen. The performance of SSWMA samples was evaluated by several tests, including dynamic shear rheometer, bending beam rheometer, Marshall test, moisture sensitivity, indirect tensile strength, and resilient modulus. Experimental results revealed that amino-based resin additive can decrease the viscosity of Transp. Infrastruct. Geotech. the bitumen by producing foam particles. This reduction of viscosity leads to reduction of asphalt production temperature as much as 25°C in application of 10 % resin by the total weight of the bitumen. It can be also concluded that SSWMA proposed acceptable moisture resistance, and modified bitumen showed a superior performance rather than the neat bitumen in the case of rutting resistance.
