Abstract

Peat soil stabilization with a mixture of biopolymer materials with a mixture variation of 0.5%, 1%, 2%, 2.5%, and 3% to soil weight. This study aims to analyze the physical properties of peat soil in the Palangka Raya area and analyze the effect of adding a mixture of chitosan biopolymer with peat soil on the value of peat soil shear strength. Examination of soil physical properties includes moisture content examination, fiber content examination, specific gravity examination and volume weight examination. Meanwhile, the examination of mechanical properties in native soils and mixed soils is carried out by direct shear test. The results showed that peat soil in the Palangka Raya area had a moisture content value of 779.87%, fiber content of 61.44%, specific gravity of 1.41, and volume weight of 1.08 g/cm3. The results of direct shear testing on native soil obtained a cohesion value (c) of 0.04 kg/cm2 and a deep shear angle value (φ) of 4.50 °. The addition of biopolymer mixtures to the original soil results in cohesion values and deep shear angle values tend to increase with each addition of mixture variations. The highest increase in cohesion value (c), deep shear angle (φ) and soil shear strength (Ï„) occurred with the addition of 2.5% biopolymer and 3% biopolymer 28-day curing. This shows that the addition of biopolymer mixtures will provide an increase in the shear strength value of the soil, which makes the soil better and more stable.

Abstract

This study investigated the fatigue performance of recycled asphalt mixtures (reclaimed asphalt pavement, RAP) rejuvenated with a bio-rejuvenator derived from coconut shells (BioCS), specifically combinations with 30% RAP using a four-point bending test with strain-controlled and compared the results with the Austroads model. The study found that adding a bio-rejuvenator increased stiffness, reduced cracking, and improved fatigue life, with the optimal dosage of 23% by weight of RA binder (bitumen from RAP). The fatigue life decreased as the strain increased but adding BioCS to AC-WC mixtures containing up to 30% RAP still provided a better fatigue life than the AC-WC control mixture. BioCS is suitable for AC-WC mixtures containing up to 30% RAP in the 200 - 400 με strain classification range. Furthermore, the fatigue failure values generated from laboratory testing using the four-point bending test were close to the Austroads model with a ratio of 0.9. This suggests that the variables from the Austroads model can be considered to build a fatigue life model of asphalt mixtures containing RAP and BioCS as rejuvenators. However, more research is needed to fully understand the long-term performance and environmental impact of using bio-rejuvenators in asphalt mixtures. Overall, this study supports using bio-rejuvenators derived from coconut shells as a sustainable alternative to petroleum-based rejuvenators for improving the fatigue life of recycled asphalt mixtures. Keywords: fatigue life, AC-WC, bio-rejuvenator, coconut shell, recycled material, four-point bending test

Abstract

The effect of using bioasphalt of coconut shell (BTK) and bitutechRAP as recycled asphalt (RA-binder) rejuvenators based on temperature susceptibility (penetration index, PI) is the aims of this study. This RA-binder has a penetration of 10 with the PI value of 0.98, which indicates that the RA-binder has experienced aging with sensitivity to average temperatures. With the bio-asphalt content of 0% to 30%, resulting in an increased penetration value and decreasing softening point, the highest PI value was 1.02 at 20% BTK content (penetration 54), and 0.57 at 16% bitutechRAP content (penetration 58). The content of bioasphalt which produces penetration of 60 – 80, has a smaller PI value, it shows that the increase in the performance of RAbinder using bio-asphalt based on the penetration parameters and the softening point is not in line with the rise in the performance of the RA binder based on PI. However, when compared with pen 60/70 with a PI of -0.31, the PI value of the RAbinder modified by bio-asphalt was better. ABSTRAK Studi ini bertujuan untuk mengetahui pengaruh penggunaan bioaspal tempurung kelapa (BTK) dan bitutechRAP sebagai bahan peremaja aspal daur ulang (RAbinder) berdasarkan parameter kepekaan aspal terhadap perubahan temperatur (penetration indeks, PI). RA binder ini memiliki penetrasi 10 dmm dengan nilai PI sebesar 0,98 yang menunjukkan bahwa aspal sudah mengalami penuaan dengan kepekaan terhadap temperatur normal. Dengan variasi kadar bioaspal 0% sampai 30% terhadap berat RA binder, menghasilkan penetrasi yang semakin meningkat dan semakin menurunnya titik lembek, nilai PI tertinggi sebesar 1,02 pada kadar BTK 20% (penetrasi 54), dan 0,57 pada kadar bitutechRAP 16% (penetrasi 58). Pada kadar bioaspal yang menghasilkan aspal dengan penetrasi 60 – 80, memiliki nilai PI yang lebih kecil, hal tersebut menunjukkan bahwa peningkatan performa RAbinder menggunakan bioaspal berdasarkan parameter penetrasi dan titik lembek tidak sejalan dengan peningkatan performa RA binder berdasarkan PI. Dibandingkan dengan pen 60/70 (PI -0,31) nilai PI dari RA binder yang dimodifikasi bioaspal lebih baik.

Abstract

The use of longitudinally laid composite pavement is currently massively used in Indonesia as part of the 272 national road standard program. This study systematically reviews and discusses the essential characteristics of semi-rigid flexible pavement widely implemented in Indonesia by comparing the bonding conditions between concrete overlays on flexible pavement; asphalt overlays on rigid pavement; longitudinal joints between flexible-flexible pavements, rigid-rigid pavements, rigid (roadway) pavements, and flexible (shoulder) pavements; and finds the potential similarity in characteristics for longitudinal joints between rigid (shoulder) pavements and flexible (roadway) pavements. The results reveal that the stiffness of the material significantly affects the remaining service life. Furthermore, high temperatures and water immersion cause stiffness of asphalt specimens loss, potentially leading to rutting and raveling. This indicates that damages due to water and temperature significantly affect the roadway, which is a structure formed with homogeneity.  Keyword: semi-rigid flexural pavement, interface conditions, stiffness modulus, residual life prediction.

Abstract

Bahu jalan berfungsi menambah kapasitas jalan dan sebagai jalur darurat. Jenisnya mencakup bahu perkerasan kaku, lentur, dan tanah, masing-masing dengan karakteristik berbeda. Pada jalan komposit, perbedaan material antara bahu dan badan jalan sering menimbulkan retak di sambungan memanjang akibat beban lalu lintas dan perubahan suhu. Pembangunan jalan komposit di sambungan memanjang kerap terjadi dan memengaruhi umur layanan jalan. Perbedaan sifat mekanik antara perkerasan kaku dan lentur menyebabkan respons berbeda terhadap beban: perkerasan kaku lebih tahan, sedangkan lentur rentan terhadap deformasi. Untuk mengatasi ketusakan ini, diperlukan desain sambungan dan metode konstruksi yang tepat, salah satunya dengan menambahkan semua takikan dan joint sealant guna memperkuat ikatan dan distribusi tegangan. Uji kuat geser menggunakan alat modifikasi marshall menunjukkan semua skenario memenuhi syarat minimum tahanan geser (32,56 - 10-2 Kg/cm2), dengan hasil terbaik pada sambungan bertakikan (SMPKDT) yaitu 729,84 - 10-2 Kg/cm2.
