For the sake of enhancing the mechanical properties and durability of asphalt concrete, many studies suggest adding different admixtures, such as waste materials in the form of filler. These admixtures have a significant influence on the performance of asphalt concrete by plying a roll in filling the voids between particles and sometimes as a cementitious material. This study aims to improve the strength of asphalt concrete by adding crushed animal bone to the mix after carbonization at a temperature of 800 Co. Seven different percentages (10, 20, 30, 40, 50, 60, and 100%) of animal bone ash as a replacement for the filler percentage were added to the optimum asphalt concrete mix. A number of tests were conducted on asphalt concrete specimens to measure Marshall stability (MS), Marshall flow value (MF), voids filled with asphalt percentages (VFA), air void percentages (VA), voids in mineral aggregate percentages (VMA), and maximum theoretical specific gravity (GMM). From the results, the maximum stability of 14.85 KN was reached when using animal bone ash of 20% as a partial replacement for the conventionally used filler (limestone). In general, there are some improvements in the physical properties of asphalt concrete with animal bone ash, which can be related to the increase in the bond between the particles of aggregates and the bitumen material. Doi: 10.28991/cej-2021-03091757 Full Text: PDF

The Impact

At present, plastic is a material that is needed by the community at large, where the impact is also very extraordinary after the plastic is used in everyday life which can cause serious problems if the management is not done properly. The problem of plastic waste does not only occur in the city of Semarang, but also in other cities, so that the Ministry of Environment and Forestry has implemented a paid plastic bag program in the short term. But this is only to deal with problems in the short term. In the long run, it will not solve the problem of "plastic waste", because the policy actually encourages people to buy plastic which, of course, will add a new burden for the community to buy it. Based on the above problems, it is necessary to utilize this plastic waste to be made into road pavement materials such as in the manufacture of Asphal Concrette Wearing Course, by making 5 mixed variations ranging from (2 to 10)% of the weight of the aggregate . This research was initiated through a survey process, material procurement, testing of stacking materials, making test specimens, testing specimens. The results of the research can show that the type of Thermosetting plastic waste has a significant influence on the Asphalt Concrete mixture AC-WC heat mixture, including: Density, Marshall Stability, Flow, VIM, VMA, MQ and the remaining Marshall Stability tend to show an increase, moderate VFA and VIMrefusal Density values tend to show a decrease. Thus the plastic waste from the Thermosetting type can be used as a partial replacement of the aggregate for the Asphalt Concrete mixture AC-WC heat mixture with a plastic waste content is limited to a maximum of 10% and at an optimum asphalt content of 5.55%. Thus this research is expected to be of benefit to the industry and the people of Semarang in relation to the use of plastic waste for road pavement.

The paper describes an investigation into mechanical properties of brick-stone bituminous concrete mix. The effect of brick-stone mix on various mechanical properties of the bituminous concrete such as Marshall stability, flow, Marshall Quotient (stability to flow ratio), Indirect Tensile Strength, stripping, rutting, and fatigue life of bituminous concrete overlay has been evaluated. In this study over-burnt brick aggregate (OBBA) and stone aggregate (SA) have been mixed in different ratios (by weight) such as 20 : 80, 40 : 60, 60 : 40, and 80 : 20, respectively. The laboratory results indicate that bituminous concrete, prepared by 20% brick aggregate and 80% stone aggregate, gives the highest Marshall stability. This bituminous concrete mix shows considerable improvement in various mechanical properties of the mix as compared to the other mixes.

This study was conducted to access the performance of asphalt concrete produced with coal bottom ash as partial replacement of cement in the mineral filler. The Marshal Mix design method of hot mix asphalt (HMA) samples preparation and testing was adopted. Fifteen (15) samples of HMA compacted and used for volumetric and stability testing at a varying percentage of bitumen contents (5.0, 5.5, 6.0, 6.5, and 7.0%,) following the Asphalt Institute and Nigeria General Specification for Road and Bridges (NGSRB) approach for determining optimum bitumen content (OBC). An Optimum bitumen content of 5.5 % was obtained and used throughout the study. Another set of 15 samples of the HMA were prepared and compacted at varying percentage replacement of cement with CBA in the order of 15, 20, 25, 30, and 35% by volume of cement to determine the optimum dosage of the coal bottom ash that will satisfy the requirements for the strength and durability of wearing course of flexible pavement. The Marshall Stability, flow, and the volumetric properties test results obtained indicated that the samples prepared with 25% CBA as filler with OBC of 5.5% satisfied the requirements of the NGSRB for wearing course of flexible pavement. Hence, the addition of up to 25% CBA by volume of cement in asphalt concrete can reduce the consumption of cement and provide a proper means of CBA disposal.Keywords- Coal Bottom Ash (CBA), Marshal Stability, Marshal Flow, Mineral filler, Optimum Bitumen Content (OBC)

The cost of cement has been on a steady increase in Nigeria making it difficult for mass housing developments. The possibility of this price hike abating is not envisaged under the current socio-economic situation in the country. One of the ways to reduce dependence on cement in construction of houses is the partial replacement of cement with pozzolanic material which are readily available with little or no cost such as the one developed by Nigeria Building and Road Research Institute (NBRRI). This study inspected the mechanical attributes of concrete made with fractional replacement of cement with NBRRI pozzolan. Concrete mix, 1:1.5:3 was designed for all specimens with w/c of 0.45. NBRRI pozzolan (0%, 3%, 6%, 9%, 12% and 15%) by weight of cement were used for concrete production. The mechanical properties were measured at 7, 14, 21 and 28 days. It was obtained from the results that workability of concrete reduces from 62.5 to 50.5 mm as the percentage of NBRRI pozzolan increases from 0 – 15% respectively. The 28-day compressive, split tensile and flexural strengths of concrete at 12% replacement of cement by NBRRI pozzolan (30.92, 3.11 and 5.48 N/mm2) were found to be comparable to control (34.93, 3.2 and 5.12 N/mm2). It is concluded that 12% replacement of cement by NBRRI pozzolan in concrete (at 28-day curing) will reduce the amount of cement, decrease the cost of concrete production and give desired strength.

The article presents the study of physical characteristics of warm mix asphalt cement concrete (WMA), components designed by the Marshall Method. Stability, flow rate, strength index, air void, and percent voids in mineral aggregate (VMA) of a total of 77 specimens were examined as a general standard specification test of the Department of Highways, Thailand. Limestone was used as aggregate. Adhesive mixtures of asphalt grade 60/70 were mixed with admixture “ADVERA” to the ratios of 0.20%, 0.25%, and 0.30% by weight of aggregate. WMA-mixing and compaction temperatures were controlled at 115°C, 120°C, and 125°C. The results were that the asphalt cement mixed with 0.25% of ADVERA (by total mixed) at 125°C shows the best mechanical properties standard, with higher value of stability (2,200lbs, i.e., more than the standard 1,800lbs), flow rate, air void, VMA and hardness index. Finally, this study indicates that asphalt concrete added with admixture ADVERA (WMA) could reduce the mixing and compaction temperature during production processes from >160°C to ≤ 125°C.
