The repetitive traffic loadings that the road experiences during its service life, combined with temperature fluctuations, cause rutting, fatigue and other forms of deteriorations, which ultimately degrade the performance and durability of pavement structures. According to test procedure specified by ASTM D1559 several hot asphalt mixture were prepared, the aggregate blend made by Job mix formula to obtain the percentage of mix material is give Hot-bin one is 26%, Hot-bin two is 23%, and Hot-bin three 51% where hot-bin one is (20-13.2mm), hot-bin two (13.2-5.0mm) and hot-bin three (5.0-0.00mm). The result of Marshall Test on mix design for hot asphalt mixture, for wearing coarse were conclude that the material used for mix design is good, which gives Marshall stability, 12.57 KN with optimum bitumen content of 5.2% (by weight of total aggregate). Hence the quality of aggregate is good but the influence of other factors such as poor drainage courses, level of ground water table, Varity of geological materials along the road rout and poor construction methodology caused the defect. The flow result of the Marshall mix design gives as 3.6 % which is approach of upper limit of specification 4%, So when flow become high in the mix it result long term deterioration of asphalt performance, hence the pavement condition along the study area has been affected by different failure types such as cracks, surface defect and disintegrating from site observation may result of this.

Marshall Stability

In pavement structures that are often submerged by water, the damage to pavement is often caused by the loss of bonds or adhesions between the aggregate and asphalt, the type of damage that occurs due to the loss of adhesion between the aggregate and asphalt is the exfoliation of asphalt granules so that the road is cracked and corrugated. To reduce the release of aggregate granules and improve the bond between aggregates and asphalt can be made with the addition of anti-exfoliating additives or antistripping agent additives. This study aims to analyze the performance of wear-coated concrete asphalt mixture (ACWC) with the addition of antistripping additives. Antistripping agents used in this study were Zycotherm, Morlife and Adhebit with variations of 0.1% addition, 0.3% and 0.5% of the weight of asphalt mixture. The results of this study showed that ACWC mixture with the addition of Zycotherm additives resulted in optimum Marshall stability and increased durability at 0.5% and Adhebit additives at 0.3% levels, while in Morlife additives although at 0.3% levels were able to show optimum marshall analysis in terms of increased durability did not show expected performance.

The objective of this study is determining the mixing and compaction temperature of the modified asphalt mixture. Results of binder tests showed that the addition of 3% SBS  to control asphalt (PG 64-16) would achieve the desired performance level (PG 76-16) a performance grade that fits our climate with traffic loads. When using 5% SBS the performance grade of binder increased three grades (PG 82-16) and when increasing SBS content to 8% the performance grade increased four grades (PG 88-16). At shear rate of 500 (s-1), the modified asphalt viscosity can be obtained at different temperatures and the viscosity temperature curve can be achieved. As a result, the mixing and compaction temperature of modified asphalt can be determined to reach 0.17 ± 0.02 Pa.s and 0.28 ± 0.03 Pa.s for mixing and compaction, respectively. It is noted that SBS modified reached a viscosity of 3 Pa.s when 8 % additive. Additive contents above these values may not be suitable for good workability and pump ability according to Superpave specifications. While addition of 5% SBS with control asphalt, more than 3.7times at 135°C Increase the viscosity. Marshall Stability test indicated that the strength for the SBS specimens increases as compared to the conventional specimens. An increase of about 39%, 74%, 102%, was observed with 3%SBS 5%SBS 8%SBS modified binders, respectively. The Marshall test results for 8%SBS binders required compaction temperatures above 175°C need to keep up quality of HMA item while limiting natural effect amid development, these proposals are unsatisfactory Modified mixtures the 5% SBS modification was determined to be the maximum useful content. The Superpave method to estimate mixing and compaction temperatures show are not practical for use with modified binders. Also,  it is observed that good agreement values between the average Marshall compaction temperature and the High Shear Viscosity Method (HSRV) and   lower than Superpave methods Where the decline ranges from 15 ºC to 17 ºC.

This study is focused on the effect of basalt fiber on the road performance of the asphalt mixture. The road performance of asphalt mixture with different dosages of basalt fiber was comprehensively evaluated using Marshall Stability test, the wheel tracking test, the three-point bending beam test and the freezing-thaw splitting test. The road performance of lignin fiber reinforced asphalt mixture and polyester fiber reinforced asphalt mixture also were tested to compare with the road performance of basalt fiber reinforced asphalt mixture. The results showed that basalt fiber can enhance mechanical properties, the low-and high-temperature performance and water sensitivity of the asphalt mixture significantly. Considering the road performance and economic benefits, the appropriate dosage of basalt fiber is about 0.3%. Marshall Stability (MS), dynamic stability (DS), the maximum bending strain and the tensile strength ratio (TSR) of asphalt mixture with 0.3% basalt fiber were increased by 19.6%, 25.5%, 22.2% and 6.0%, respectively. Basalt fiber has certain advantages in improving the low-temperature performance of asphalt mixture by comparison with lignin fiber and polyester fiber.

The main goal of this paper is to propose the performance parameter for binder which is good for quality prediction of asphalt mixture in frame of resistance to permanent deformation (rutting). Additionally, correlation between, proposed by the authors, repeatable shear creep-recovery test carried out on binder and bituminous mixture rutting test is under evaluation. The results are analysed and correlation between the proposed functional parameter and rut depth is shown. Thanks to that it is possible to claim that expensive rutting test procedure can be assisted with simple test carried out in dynamic shear rheometer at the initial mix design procedure.

Fiber reinforcement as an available attempt has been proved to be effective in improving the toughness of asphalt concrete and is becoming a new method for highway maintenance. When fiber modified asphalt mixture is used as the surface course of a reconstructive pavement, the interface bonding property between top and lower layers seems to become a crucial factor in the road performance of the long lasting pavement. The primary objective of the research is to study the influence of fiber inclusions on the interfacial shear property of the pavement. With the purpose of discussing the shear strength of the interface between Bonifiber modified asphalt mixture top layer and the normal asphalt mixture layer，the laboratory shear test was developed on MTS-810. Four kinds of double-layered cylindrical specimens were made to simulate the different pavement structures. Test results show that the overlaying with Bonifiber modified asphalt mixture improves not only the general road performance but also the interface property. It is concluded that, the interface property of pavement with fiber reinforced top layer behaves much better than that with normal asphalt concrete one.

Abstract: Good asphalt concrete and good care are required for the highway construction, to support the road capabilities and to raise the quality of asphalt mixture, one step is by adding additives into the asphalt. Additive material used plastic bag waste, while Basalt stone used as material that is raw material from hills. Waste plastic bag can be used in various ways, one of them by adding plastic into an asphalt mixture. Mixing plastic waste into the highway construction has two aims, to minimize plastic waste and to improve the quality of roads. This study was conducted to determine the effect of plastic bag waste use as a substitution of Asphalt Pen 60/70 by using Basalt aggregate toward Marshall’s characteristics of asphalt concrete AC-BC mixture. Initial phase of this research was to calculate Optimum Bitumen Content (OBC). The addition of varied plastic bag waste as an additive respectively 2%, 4%, 6%, and 8% in OBC-0.5, OBC, and OBC + 0.5 from the initial OBC of 5.35%. From the three OBCs, it was taken the highest value at OBC +0.5 of 3.3% for the production of test specimens in plastic OPC variation percentage of ± 2% by determining Marshall’s value and durability. Stability value continued to rise in the percentage of plastic bag waste content variation respectively 1.3%, 3.3%, and 5.3% by 1470.48 kg, kg 1476.28, and 1489.28 kg with 30 minutes immersion (temperature = 600C ) and 1286.42 kg, kg 1316.35, 1345.41 kg with a 24-hour immersion (temperature = 600C). This condition is caused by the additive content that is mixed with asphalt pen 60/70 in the mixture, it causes the adhesion of asphalt with aggregate become better until it reaches a certain value limit, which is at the limit of 5.3% with the best stability value of 1489.28 kg in the 30 minutes immersion and 1345.41 kg in 24-hour immersion. From the comparison of both stabilities, the obtained durability values were 99.84%, so that it met specifications for additive-added mixtures, ≥ 90%.Abstrak: Pembangunan konstruksi jalan raya diperlukan beton aspal yang baik dan perawatan yang baik pula, untuk mendukung kemampuan jalan tersebut dan menaikan mutu campuran beraspal salah satunya dengan menambahkan bahan aditif kedalam aspal.. bahan aditif digunakan limbah plastik kresek, sedangkan untuk material digunakan batuan Basalt yang merupakan bahan baku dari gunung. Limbah sampah plastik ini bisa dimanfaatkan dengan berbagai cara, salah satunya dengan cara menambahkan plastik kedalam suatu campuran aspal. Mencampur sampah plastik kedalam kontruksi jalan raya mempunyai dua tujuan, yaitu meminimalkan sampah plastik dan meningkatkan kualitas jalan. Penelitian ini Tujuan Penelitian dilakukan untuk mengetahui pengaruh pemakaian limbah plastik kresek sebagai subsitusi Aspal Pen 60/70 dengan menggunakan agregat bassalt terhadap karakteristik Marshall campuran aspal beton AC-BC. Tahapan awal penelitian adalah mencari Kadar Aspal Optimum (KAO). Penambahan variasi kantong plastik bekas sebagai aditif secara berturut-turut yaitu 2%, 4%, 6%, dan 8% pada KAO-0,5, KAO dan KAO+0,5 dari KAO awal 5,35%. Dari ketiga KAO tersebut diambil nilai yang tertinggi yaitu pada KAO+0,5 sebesar 3,3% untuk pembuatan benda uji pada persentase variasi plastik KPO ±2% dengan mendapatkan nilai marshall dan durabilitas. Nilai stabilitas terus meningkat pada persentase variasi kadar plastic bekas 1,3%, 3,3% dan 5,3% masing-masing sebesar 1470,48kg, 1476,28kg, dan 1489,28kg dengan rendaman 30 menit (suhu 600C) dan1286,42kg, 1316,35kg, 1345,41kg dengan rendaman 24 jam (suhu 600C). Kondisi ini disebabkan oleh kandungan dalam aditif yang bercampur dengan aspal pen 60/70 di dalam campuran menyebabkan daya lekat aspal dengan aregat menjadi lebih baik hingga mencapai batas nilai tertentu, yaitu pada batas 5,3% dengan nilai stabilitas terbaik yaitu sebesar 1489,28kg pada rendaman 30 menit dan sebesar 1345,41kg pada rendaman 24 jam. Dari perbandingan ke dua stabilitas tersebut maka diperoleh nilai durabilitas sebesar 99,84% sehingga telah memenuhi spesifikasi untuk campuran yang ditambahkan aditif, yaitu sebesar ≥ 90%.
