“…This study is divided to two stages: firstly, the materials cost are arrived from Publics Works Department Standard Scheduled of Rates (PWD -SSR), Government of Tamilnadu, India and market survey. The Optimum Binder Content (OBC) for all the mixtures is taken from the published report (Devulapalli et al, 2019b). In the second stage the production cost of the asphalt mixture, and the RAP incorporated asphalt mixtures with rejuvenator are evaluated.…”

“…gives the production cost of the RAP incorporated asphalt mixtures with WVO. The virgin aggregate and RAP aggregate gradation, and the OBC for all the mixtures are taken from the published work [10] and same is used in the cost calculation for each mixture. Since the price of the WVO and cellulose fibre are not available in the PWD-SSR, then the rate is taken based on the local market survey.…”

“…The main objective of the study is to evaluate the influence of RAP content and rejuvenator dosage on the cost-benefit ratio of the Stone Matrix Asphalt mixtures (SMA). SMA is a gap graded pavement which consists 70% of coarse aggregate which forms an aggregate skeleton and a fair amount of fine aggregate helps to fill the voids present in the coarse aggregate and give better stone-on-stone contact and gives strength to the mixture [10,11].…”

It is desirable to incorporate Reclaimed Asphalt Pavement into the asphalt mixtures, which provides several benefits i.e. economic, environmental and performance. It is necessary to study, the economic analysis of the RAP since that incur several contingencies to the asphalt mixtures. In this study, a simple approach is used to evaluate the production cost of the asphalt and RAP incorporated asphalt mixtures. Apart from that Waste Vegetable Oil (WVO) is used as a rejuvenator to enhance the properties of the mixture. In this study, asphalt mixture production cost is evaluated and cost of each material is taken from the Public Works Department Standard Scheduled of Rates (PWD – SSR) and the market survey techniques are followed. From the cost-benefit ratio, it is observed that the reduction in the Optimum Binder Content (OBC) provides great economic savings to the production cost. The incorporation of the RAP reduced the asphalt content and reduced the production cost of the asphalt mixtures. The addition of the WVO further reduced the OBC but increased the production cost compared to the non-rejuvenated mixture. The increase in the production cost is due to the extra cost invested on the WVO and other contingencies.

“…Steel slag has a higher specific gravity of between 3.01 and 3.67 [44][45][46][47], although coconut waste and palm oil shells have high absorption values of between 13.8 and 25% because of their porous structure [48][49][50][51][52]. The Los Angeles abrasion for the wastes ranges between 11.29 and 25.3% [44,45,[53][54][55][56][57][58][59][60], which is lower than the 55% for CBA [24]. The lower Los Angeles abrasion values indicate that the materials are tougher and more resistant to abrasion than CBA.…”

A Review of the Utilization of Coal Bottom Ash (CBA) in the Construction Industry

et al. 2021

View full text Add to dashboard Cite

One effective method to minimize the increasing cost in the construction industry is by using coal bottom ash waste as a substitute material. The high volume of coal bottom ash waste generated each year and the improper disposal methods have raised a grave pollution concern because of the harmful impact of the waste on the environment and human health. Recycling coal bottom ash is an effective way to reduce the problems associated with its disposal. This paper reviews the current physical and chemical and utilization of coal bottom ash as a substitute material in the construction industry. The main objective of this review is to highlight the potential of recycling bottom ash in the field of civil construction. This review encourages and promotes effective recycling of coal bottom ash and identifies the vast range of coal bottom ash applications in the construction industry.

“…Waste oils can be categorized differently according to their constituents and source. Among different types of waste oil, the potential of waste engine oil (WEO) and waste cooking oil (WCO) have been explored by many researchers [9][10][11][12][13][14][15][16][17][18]. These studies concluded that WCO and WEO can significantly affect different characteristics of asphalt mixture [19][20][21].…”

Comparative Evaluation of Waste Cooking Oil and Waste Engine Oil Rejuvenated Asphalt Concrete Mixtures

2020

In road construction, different types of waste oil have been recommended to overcome the stiffening effect of reclaimed asphalt pavement content. However, the selection of an effective rejuvenator based on a comparative study can lead to using the resources more efficiently. In this study, waste cooking oil and waste engine oil are used to rejuvenate three different percentages (30%, 40%, and 50%) of reclaimed asphalt pavement following the current maximum industrial adaptability. The waste oil rejuvenated mixtures are compared to the fresh mixture, and mixtures rejuvenated with commercial rejuvenator. The moisture sensitivity, indirect tensile strength, and resilient modulus of the various asphalt mixtures are analyzed. Based on the statistical analyses and overall ranking, it is concluded that 7% of waste engine oil performs better till 40% of reclaimed asphalt pavement, whereas 13% of waste cooking oil can be used till 50% of reclaimed asphalt pavement.
