The spent fluid catalytic cracking (SFCC), waste from the petroleum industry, is nonstop increasing and causing environmental pollution in Vietnam. This study is an attempt to recycle SFCC in pavement construction. The study investigated the effect of SFCC, as a filler material in the hot-mix asphalt (HMA), on the essential characteristics of the asphalt concrete mix. First, the optimum percentages of bitumen and SFCC rate were investigated based on the Marshall design method. The HMA with SFCC showed more enhanced stability, flow, and other Marshall properties than the asphalt concrete mixture with the optimum limestone filler of 5%. Besides, the effects of SFCC rates on Marshall characteristics were explored. Second, performance tests were conducted to compare the mix with the different optimum content fillers of SFCC, limestone, and Portland cement. The tests include wheel tracking, indirect tensile, fatigue, and dynamic modulus tests to evaluate the performance of HMA with SFCC. It was found that the asphalt mixture with the optimum SFCC filler content can enhance pavement performance and improve the rutting and cracking resistance of the asphalt pavement.

Technology in transportation used available resources to make it safe, fast, suitable, easy, economic, and environmental to transport people and goods. Olive Husk became an environmental problem as waste materials especially in the Middle East where huge quantities are found. The objective of this research is to investigate the effect of addition of Olive Husk Ash (OHA) on the properties of asphalt concrete mixtures. Marshall Test was used to perform the asphalt concrete mixture by the addition of OHA to the binder of asphalt; different percentages of OHA (0, 5, 10, 15, and 20%) by volume were added to the binder. Five percent of asphalt cements (5, 5.5, 6, 6.5 and 7%) by weight and limestone aggregate were used for preparing asphalt mixture specimens to find the optimum content of asphalt that could be used in the binder. Tests on flow, stability, air void percentage and void in mineral aggregate, retained stability, stiffness, and retained stiffness were made. The principle results on OHA as filler in Asphalt binder improves the Marshall Stability, and void in mineral aggregate and decrease in flow, retained stability, stiffness, and retained stiffness with a 10%-15% of olive husk ash replacement of asphalt binder. The contribution that OHA could be used as a pavement construction material in field.

The non-renewable constituent used in asphalt concrete consumed large amount of materials resulting an increase in the price of asphalt mixture and consequently the cost of road development. On the other hand, huge industrial waste being generated daily from human activities causes environmental degradations. Thus, the study evaluates the performance of fly ash (FA) in asphalt concrete development targeted for road application. The aggregate, bitumen, and fly ash were characterized before being used. The stone dust in asphalt mixture was replaced with FA in predetermined proportions of 2, 4, 6, and 8% to produce a cylindrical specimen of asphalt mixture concrete. Marshal stability test, flow test, X-ray diffraction (XRD), X-ray Fluorescence (XRF) and Scanning Electron Microscope (SEM) was conducted on the composite samples. From the results, stability values of 7.39, 7.70, 7.90 and 8.22 KN was obtained at 2, 4, 6 and 8% replacements, respectively. Hence, the optimum value of 8.22 KN obtained from 8% partial replacement with FA is adequate for heavy traffic while other partial replacement from 2- 6% with stability within the range of 7.39-7.90 KN is suitable for medium traffic in accordance with the criteria for the marshal mix design method provided by Asphalt institute (1997). Corresponding values of 3.7, 3.5, 3.3 and 3.0 mm was obtained for the flow. The flow, air void, void in mineral aggregates and void filled with bitumen results all satisfied Nigeria general specification for road and bridges (1997). Therefore, fly ash can be used as partial replacement in asphaltic concrete to enhance the performance of the mix with a reduced cost for pavement construction.

The property of aggregate has a significant effect on the performance of asphalt mixture because of its high proportion. Asphalt mixture prepared by some kind of aggregate cause the inadequate compaction problem, which results in moisture damage due to its large air void. Limestone manufactured sand is considered as one of the useful solution to overcome the compaction problem. In this paper, fine aggregate is substituted by different proportion of limestone manufactured sand (LMS). The effect of replacement ratio on volume properties and pavement performance is studied. The results show that the limestone manufactured sand can improve the pavement performance and is benefit to the compaction of andesite asphalt mixture. Furthermore, this research also provided some valuable parameters for guiding the pavement construction in the future.

Engineers are constantly trying to improve the performance of the flexible pavements. The main surface distress types which cause maintenance and disruption are rutting and fatigue cracking. For solving these problems, many studies have been carried out until now, ranged from changing gradation to adding polymers and fibers to asphalt mixture. In this study, polypropylene additive was selected as fiber additive because of low costing and having good correlation with asphalt pavement. Three type of polypropylene additive in the length 6, 12 and 19 mm were selected and used at five different percentages in the asphalt concrete mixture. Asphalt specimens were analysed by Marshall Analysis and finally tested by Marshall Stability apparatus. Adding polypropylene increased Marshall Stability (38%), and decreased Flow (39%). These results show that polypropylene can be helpful for increasing pavement life.

In an effort to increase the strength of mixed asphalt concrete structure ( AC-WC ) in addition to the use of hot asphalt mixture with new specification, the selection of material type used is very important. In addition to asphalt, both coarse and fine aggregates and fillers are one component in a pavement construction that has a large role. Therefore further research is needed on the influence of temperature variation and percentage of filler fly ash to the modulus of r esilien which is good so that it can be applied and able to overcome the damages. In this research is divided into 3 (three) stages namely (1) the selection of materials; (2) the preparation of the specimen; (3) research and data analysis. Asphalt concrete mixed test (AC-WC) showed that Asphalt Optimum (KAO) content with 5.5% asphalt content with VIM value of 3.70%, VMA of 19.00%, Stability of 1,152.93 kg, Flow of 2.78 mm and MQ of 417.39 kg/mm. The result of mixed asphalt concrete (AC-WC) asphalt with filler fly ash test showed that the optimum mixture content was 7% filler content with VIM value 4,21%, VMA 19,21%, Stability 1326.10 kg, Flow of 3.69 mm and MQ of 360.13 kg/mm. Dalam upaya meningkatkan kekuatan struktur campuran beton aspal lapisan aus (AC-WC) selain perlu adanya penggunaan campuran beraspal panas dengan spesifikasi baru, pemilihan jenis material yang digunakan adalah sangat penting.

This research tries to use an RCC (Residium Catalytic Cracking) Pertamina waste filler from the oil process in Balikpapan which is expected to increase the resistance of asphalt concrete pavements to damage caused by weather and traffic. The purpose of this study was to analyze the effect of the duration of immersion on the characteristics of hot asphalt mixtures (AC-WC) using Spent Catalyst RCC (Pertamina waste) as a filler. The method used is the Marshall characteristic test with a variation of immersion 2 days, 4 days, 7 days, and 11 days. The results showed that the use of an RCC (Residium Catalytic Cracking) Pertamina waste would affect the asphalt concrete mixture. Asphalt concrete mixture has decreased strength along with the duration of immersion. Longer immersion causes the value of stability to decrease. Soaking stability values within 30 minutes obtained 1,684.27 kg. The immersion stability value within 2 days was reduced to 1,420.09 kgPenelitian ini mencoba menggunakan sebuah filler limbah pertamina RCC (Residium Catalytic Cracking) dari proses minyak di Balikpapan yang diharapkan meningkatkan ketahanan trotoar beton aspal terhadap kerusakan yang disebabkan oleh cuaca dan lalu lintas. Tujuan penelitian ini adalah untuk menganalisis pengaruh durasi perendaman terhadap karakteristik campuran aspal panas (AC-WC) yang menggunakan Spent Catalyst RCC (limbah pertamina) sebagai filler. Metode yang digunakan yaitu uji karakteristik Marshall dengan variasi perendaman 2 hari, 4 hari, 7 hari, dan 11 hari. Hasil penelitian menunjukkan bahwa penggunaan sebuah limbah pertamina RCC (Residium Catalytic Cracking) akan mempengaruhi campuran beton aspal. Campuran beton aspal mengalami penurunan kekuatan seiring dengan lamanya durasi perendaman. Perendaman yang lebih lama menyebabkan nilai stabilitas berkurang. Nilai stabilitas perendaman dalam waktu 30 menit diperoleh 1.684,27 kg. Nilai stabilitas perendaman dalam waktu 2 hari berkurang ke 1.420,09 kg
