Abstract

Abstract Pavement Flexural Stiffness Modulus and Phase Angle tend to bend due to over load of vehicle. Using Reclaimed Asphalt Pavement (RAP), in this case asphalt recycling will decrease deformation endurance of asphaltic mixture. The lower deformation endurance of asphaltic mixture, the worse asphaltic mixture quality is. Therefore modified of asphalt recycling, must be done to improve deformation endurance of asphalt. This research using Styrene-Butadiene-Styrene (SBS) which is elastomer polimer as asphalt modifier. Variation of SBS polimer are 2.5% and 5% of asphalt weight and variation of RAP are 20% and 30% of mixture weight. The value of Flexural Stiffness Modulus and Phase Angle was determined by Fatique testing using Four Point Loading Apparatus. According to the result, the highest Flexural Stiffness Modulus is 5,763.67 MPa which found in variation RAP 30% and SBS 5%. This mixture composition also have the lowest Phase Angle that is 23.33°. The result showing that the stiffness will be increase by adding Reclaimed Asphalt Pavement (RAP) and SBS Polimer. Keywords: Flexural Stiffness Modulus, Phase Angle, Reclaimed Asphalt Pevement (RAP), SBS polimer  Abstrak Nilai Modulus Kekakuan Lentur dan Sudut Fase campuran beraspal memperlihatkan kecenderungan material untuk mengalami deformasi akibat beban yang diterimanya. Penggunaan perkerasan daur ulang, dalam hal ini aspal daur ulang, akan menurunkan tingkat ketahanan campuran beraspal terhadap deformasi akibat beban yang diterimanya. Makin rendah tingkat ketahanan campuran terhadap deformasi yang terjadi, makin buruk mutu campuran tersebut. Untuk itu diperlukan modifikasi terhadap aspal daur ulang sehingga dapat memperbaiki tingkat ketahanannya terhadap deformasi yang terjadi. Pada penelitian ini digunakan modifikasi aspal dengan tambahan polimer elastomer, yaitu polimer Styrene-Butadiene-Styrene dengan persentase 2,5% dan 5% terhadap berat aspal. Kandungan material daur ulang yang digunakan adalah sebesar 20% dan 30% terhadap berat campuran. Nilai-nilai Kekakuan Lentur dan Sudut Fase diperoleh dari pengujian kelelahan campuran menggunakan Four Point Loading Apparatus. Hasil yang diperoleh menunjukkan bahwa nilai Modulus Kekakuan Lentur tertinggi diberikan oleh campuran dengan kandungan material daur ulang 30% dan Styrene-Butadiene-Styrene 5%, yaitu sebesar 5.763,67 MPa. Komposisi campuran ini juga memberikan nilai Sudut Fase yang terkecil, yaitu 23,33°. Hasil analisis menunjukkan bahwa penambahan polimer SBS pada material daur ulang meningkatkan kekakuan. Kata-kata kunci: Modulus Kekakuan Lentur, Sudut Fase, material daur ulang, polimer SBS

Abstract

The earthquake in Central Sulawesi in September 2018, accompanied by tsunami and liquefaction, caused very significant infrastructure damage, especially in Palu City. Roads are one of the vital infrastructures that have suffered a lot of damage. Efforts to rehabilitate roads due to the disaster have been carried out and have left quite a lot of old road pavement material. This dredging material needs to be optimized for use, especially in new pavements. Because this can make new materials efficient, especially aggregates in the pavement mixture. The use of new aggregates can be conditioned to a minimum by making efficient use of recycled materials. Namely by determining the type of pavement layer that best suits the gradation conditions of the recycled material. The purpose of this study was to obtain the type of flexible pavement layer that best suits the gradation of post-disaster recycled material based on standard specifications. The method used is sieving analysis of recycled material from several locations in Palu City that were affected by the disaster. The results showed that the use of post-disaster recycled materials, based on the recycled aggregate suitability value, was the AC-WC layer of 78.33%, the HRS-WC layer of 70%, the AC-BC layer of 66.67%, the layer of AC-Base is 41.67% and SMA-Thin layer is 40%. Based on the grading analysis, post-disaster recycled material in Palu City is most suitable for the AC-WC layer type because the addition of new aggregate is the least, resulting in the most optimal use of recycled material.Kata kunci: Recycled Material, Post Disaster Material, Flexible Pavement, Gradation

Abstract

Increased population growth boosted road transport infrastructure. So it takes a good pavement structure. Efforts to increase the hot asphalt mix with the new specification implies the use of hydrated lime as an anti stripping agent in the mix asphalt. This study aimed to investigate the characteristics of the use of hydrated lime as a filler that uses a mixture of asphalt with aggregate filler composition arrangement between a stone dust and hydrated lime on Asphaltic Concrete - Wearing Course (AC - WC). The composition is lime: stone dust is 0%: 100%, 25%: 75%, 50%: 50%, and 75%: 25%.  The results of this research indicate that the lime filler significantly affects the quality of the mix, the value of stability, flexibility, durability, density, VIM, VMA, VFB, and flow with the value of F table greather than F arithmetic based on Anova two factor analysis. From the research lime used 0%, 25%, and 50%, due to the variation of 75% lime can not set the value of the optimum bitumen content. Stability values obtained at optimum bitumen content in lime variation of 0%, 25% and 50% is 1114,862 kg, 1243,425 kg, and 1167,645 kg. And for Retained Marshall Stability value of 94,303%, 98.301% and 99.202%. The quality of the mix with hydrayed lime as a filler is better. Based on the value of Marshall Stability and durability, it can be stated that the addition of hydrated lime as a filler can improve the quality of the mix.

Abstract

Pavement recycling is an appropriate technology for constructing and restoring road pavement structures due to the limited supply and high cost of pavement materials. This study aims to improve the recycled mix's performance by replacing the fine aggregate in the recycled mix for road pavement with Buton Granular Asphalt (BGA). The percentage of recycled material (Reclaimed Asphalt Pavement/RAP) in the mixture was limited to 20% and 30% by weight of the total mixture. BGA was added by 3%, 6%, and 9% in each mixture with the RAP variation. Mixture performance was obtained through Indirect Tensile Strength (ITS) testing. The ITS test results showed that the ITS value of the mixture with RAP and BGA increased by an average of 4.7–15% compared to the mixture without RAP and BGA. The Toughness Index (TI) value increased by 3.5–19.8% with the addition of RAP. With the addition of 3% BGA, the TI value tends to increase and subsequently decrease up to 9% BGA levels. The result indicated that adding 30% RAP and 3% BGA to the mixtures improved pavement performance and could be a solution to increase the elasticity and fracture resistance of the mixture. Doi: 10.28991/CEJ-2023-09-06-09 Full Text: PDF

Abstract

Pemanfaatan material perkerasan jalan pasca bencana di Kota Palu dan penggunaan material lokal yaitu Asbuton Butir Lawele diharapkan dapat bersinergi dengan baik pada campuran Beton Aspal Lapis Aus (AC-WC). Tujuan dari penelitian ini adalah untuk menguji pengaruh penggunaan material daur ulang (RAP) dan asbuton butir terhadap sifat volumetrik campuran AC-WC. Bahan RAP yang digunakan dalam campuran adalah 20% dari berat campuran dan variasi asbuton yang digunakan adalah 0%, 3%, 6% dan 9% dari berat campuran. Berdasarkan hasil pengujian diketahui bahwa penambahan material RAP dan asbuton butir pada campuran AC-WC dapat mempengaruhi sifat volumetrik campuran. Nilai rongga dalam campuran (VIM) dan rongga dalam agregat mineral (VMA) akan meningkat seiring dengan peningkatan persentase asbuton. Sebaliknya, rongga yang terisi aspal (VFB) akan berkurang dengan bertambahnya jumlah asbuton. Sehingga dapat dikatakan bahwa campuran AC-WC yang mengandung RAP dengan penambahan asbuton butir, akan mengalami perubahan volumetrik jika dibandingkan dengan campuran tanpa RAP dan asbuton butir. ABSTRAK Utilization of post-disaster pavement materials in Palu City and Indonesian local materials, namely Asbuton Butir Lawele, are expected to synergize well in Asphaltic Concrete Wearing Course (AC-WC) mixture. This studio aims to examine the effect of recycled materials (RAP) and granular asbuton on the volumetric properties of the AC-WC mixture. The RAP material used in the mix is 20% of the mixture weight and variations of asbuton used are 0%, 3%, 6% and 9% of the mixture weight. Based on laboratory results, it was found that the addition of RAP material and granular asbuton to the AC-WC mixture could affect the volumetric properties of the mix. The value of voids in the mixture (VIM) and voids in mineral aggregates (VMA) will increase as the proportion of asbuton increases. On the other hand, the void filled with asphalt (VFB) will decrease with the increasing number of asbuton. So it can be said that the AC-WC mixture containing RAP with the addition of granular asbuton, will experience volumetric changes compared to the mix without RAP and granular asbuton.

Abstract

The penetration index (PI) of bitumen is one of the parameters to measure the temperature sensitivity of bitumen. The bitumen quality will decrease if the bitumen's resistance to temperature changes decreases. This evaluation was based on previous research that used recycled bitumen from the extraction process. Bitumen modification was done by adding different percentages of recycled bitumen to fresh bitumen. PI values were determined using the Pfeiffer and Van Doormall equation, which shows the relationship between penetration and bitumen softening point. Based on the analysis, it was found that adding recycled bitumen up to 30% can increase the PI of bitumen, but the PI of bitumen will decrease with the addition of RAP. Adding recycled bitumen can reduce the bitumen's resistance to temperature, so a rejuvenating agent is needed to restore the physical properties of bitumen containing a high percentage of recycled bitumen. ABSTRAK Indeks penetrasi (PI) bitumen merupakan salah satu parameter untuk mengukur sensitivitas bitumen terhadap temperatur. Sensitivitas bitumen terhadap temperatur dipengaruhi oleh perubahan viskoelastis bitumen. Kualitas bitumen akan menurun bila ketahanan bitumen terhadap perubahan temperatur juga menurun. Evaluasi ini didasarkan pada penelitian sebelumnya yang menggunakan bitumen daur ulang dari proses ekstraksi. Modifikasi bitumen dilakukan dengan menambahkan bitumen daur ulang dengan presentase yang berbeda pada fresh bitumen. Nilai PI ditentukan menggunakan persamaan Pfeiffer dan Van Doormall, yang menunjukkan hubungan antara nilai penetrasi dan nilai titik lembek bitumen. Berdasarkan hasil analisis diperoleh bahwa penambahan bitumen daur ulang hingga 30% dapat meningkatkan nilai PI bitumen, namun PI bitumen akan menurun seiring penambahan RAP. Berarti bahwa penambahan bitumen daur ulang dapat menurunkan ketahanan bitumen terhadap temperatur sehingga bahan peremaja diperlukan untuk mengembalikan sifat fisik bitumen yang mengandung bitumen daur ulang dengan persentase yang tinggi.
