“…For example, between 1979 and 2002, the Florida Department of Transportation reported that reusing of RAP in the production of HMA mixtures could result in $224 million saving which is equal to two-thirds of its annual resurfacing budget [59]. Additionally, the cost-benefit of using RAP in HMA mixtures for some plants was investigated by Franke and Ksaibati [78]. Results of this study showed that there was a remarkable amount of savings ($40.87 per ton) in the application of RAP in hot mix asphalt.…”

During recent decade, the pavement sustainability has received much attention by road agencies, companies, governments and research institutes. The aim of this paper is to introduce and evaluate the sustainability of the technologies developed or underdeveloped to address environmental issues of asphalt mixtures, and the waste materials and by-products that can be recycled and reused in asphalt production. Warm Mix Asphalt (WMA) technology, the most popular waste materials to substitute neat binder (crumb rubber modifier (CRM), recycled plastic (RP), vacuum tower bottoms (VTB)) and/or virgin aggregates (reclaimed asphalt pavement (RAP), reclaimed asphalt shingles (RAs), construction and demolition (C and D) wastes, steel and copper slags), and bio-binders were evaluated with respect to their environmental and economic benefits and engineering performance as the main components of pavement sustainability. The performance evaluation was carried out by examining rutting, moisture susceptibility, thermal and fatigue cracking resistance. Two main environmental impacts, greenhouse gas (GHG) emission, and energy consumption were considered to study the environmental effects of these technologies and materials. Additionally, the economic effect was investigated considering initial cost and long-term benefit. Results of investigation illustrated that although each individual technology and waste material is valuable in terms of performance and/or the environment, specific combinations such as WMA + RAP, WMA + CRM, RAP + CRM, and WMA + CRM + RAP lead to further benefits. Notably, these combinations suffer from a lack of comprehensive economic analysis, thus, their sustainability cannot be fully assessed and is prone to future studies.

“…Based on the similarity in these procedures between recycled and virgin materials, the costs associated with transporting, milling, placing, and compacting are not included in this cost analysis. Additionally ignored are social and environmental benefits, whose worth is hard to quantify and differ between projects [15].…”

Paving is regarded as one of the essential layers in the construction of a road since it directly affects traffic loads and is subject to environmental factors. As a result, appropriate asphalt mixes that can support the designed traffic loads and environmental conditions must be developed. From an economic and environmental aspect, recycling the waste from the old pavement is a good step in this regard. This paper comprises detailed laboratory work that tested the impact of using different recycled asphalt pavement (RAP) content in addition to 3% crumb rubber (CR). The (CR) is used as fine aggregate. The tests were evaluated based on the response of hot asphalt mixes (HMA). The objectives of this study are to analyze the volumetric or weight change in hot mix asphalt of the different percentages and then analyse the costs of Kut-Maysan Road as a case study in case of using the different percentages of RAP and CR. The results show that the cost analysis of using RAP reduces the cost of a produced ton of HMA. On the other hand, the use of CR increases the cost of producing HMA. Using 10% RAP reduces the cost of one ton of HMA by 0.64 $ while using 20% RAP reduces the cost by 1.10 $, and the cost is reduced by 1.41 $ when using 30% RAP. On the other hand, the use of 3% CR with 10% RAP increased the production cost of one-ton HMA by 1.47 $. While decreased by 0.82 $ with 20% RAP content and by 0.28 $ with 30% RAP.

“…Amerika Birleşik Devletlerinde her yıl yaklaşık 500 milyon ton asfalt üretiminin yaklaşık %15'ini sökülmüş asfaltın geri kazanılması ile elde etmekte ve yılda 300 milyon $ tasarruf sağlanmaktadır [1]. Franke ve Ksaibati [14] çalışmasında sıcak asfalt karışım, stablize yollar ve temel tabakası olmak üzere 3 farklı karayolu uygulaması için RAP kullanımının maliyet açısından sağlayacağı faydaları araştırmıştır. Yapılan maliyet analizine dayanarak, karışıma katılacak her bir ton RAP malzemesi için sıcak karışımlarda %40,87, stabilize yollarda %17,07 ve temel tabakalarında %15,71 kâr edildiği belirtilmiştir.…”

Bu çalışmada farklı filler içeriğine sahip RAP agregası-doğal agrega (DA) karışım oranına filler içeriğinin etkisi incelenmiş ve maliyet analizi yapılmıştır. Sonuç olarak filler içeriği düşük RAP kullanılması durumunda daha yüksek oranda RAP kullanılabileceği ve yaklaşık olarak karışımda kullanılan RAP oranı kadar malzeme maliyetlerinde azalma olduğu belirlenmiştir./ In this study, the effect of filler content on the mixing ratio of RAP with different filler content and natural aggregate (NA) was examined and cost analysis was made. As a result, it was determined that if RAP with low filler content is used, a higher rate of RAP can be used in mixtures and there is a decrease in material costs approximately as much as the RAP ratio used in the mixture Şekil.

Schematic diagram of the study workflow Amaç (Aim) Bu çalışmada, farklı filler içeriklerine sahip RAP agregalarının DA'ya alternatif olarak kullanılabilirliğinin incelenmesi ve etkilerinin değerlendirilmesi amaçlanmıştır./ In this study, it was aimed to examine the usability of RAP aggregates with different filler contents as an alternative to NA and to evaluate their effects. Tasarım ve Yöntem (Design & Methodology)RAP agregalarının kullanım oranları deneysel olarak değerlendirilmiş ve karışımlar için maliyet analizi yapılmıştır. / The usage rates of RAP aggregates were examined experimentally and the optimum mixture ratio was evaluated by performing cost analysis for the mixtures. Özgünlük (Originality)Farklı RAP agregaları daha önce PMT tabakasında kullanılmamıştır. Bu nedenle, hem içerik hem de sonuçları bakımından orjinal bir çalışmadır./ Different RAP aggregates have not been used in the PBL. Therefore, it is an original study in terms of both content and results. Bulgular (Findings)RAP malzemelerinin PMT tabakalarında kullanılabileceği ve maliyeti belirgin oranda düşürdüğü mevcut görülmüştür./ It has been observed that RAP agregates can be used in PBLs and significantly reduce the cost. Sonuç (Conclusion)Düşük filler oranına sahip RAP agregasının PMT tabakası için daha yüksek oranlarda DA ikamesi olarak kullanılabileceği ve daha düşük maliyet sağlayacağı görülmüştür. / It has been observed that the RAP aggregate with a low filler ratio can be used as a NA substitute for the PBL at higher rates and provides lower costs.
