Abstract

Abstrak Sampah plastik saat ini sudah menjadi suatu permasalahan yang sangat umum di lingkungan hidup, upaya pengurangan dan pencegahan telah banyak dilakukan, namun hasil yang diperoleh tidak sesuai dengan pertumbuhan dan penggunaan yang terus meningkat khususnya plastik yang tidak terkelola dengan baik. Salah satu upaya yang harus dilakukan untuk mengurangi limbah plastik adalah dengan memanfaatkan viscoelastisity plastik dan dikombinasikan dengan karbon arang tempurung kelapa serta material tersebut akan dimanfaatkan sebagai bahan pengganti sebagian aspal pada lapisan AC-WC. Tujuan penelitian ini untuk mengetahui besarnya variasi campuran plastik LDPE dan arang tempurung kelapa yang dapat dimanfaatkan untuk memenuhi parameter marshall pada lapisan AC-WC. Metode yang digunakan pada penelitian ini adalah metode eksperimental yang bersifat deduktif. Hasil penelitian yang telah dilakukan dengan kadar variasi plastik LDPE 5%, 10%, 15% dikombinasikan dengan arang tempurung kelapa 5%, 10% dan 15% hasil yang diperoleh dari pengujian marshall untuk variasi 10%, VIM dan VFA tidak memenuhi, variasi 20% VIM dan VFA tidak memenuhi dan variasi 30% hanya flow yang tidak memenuhi spesifikasi yang disyaratkan oleh Bina Marga Tahun 2018 Revisi II, sehingga dapat disimpulkan bahwa plastik LDPE dan arang tempurung kelapa tidak dapat dimanfaatkan sebagai substitusi sebagian aspal pada variasi 10%, 20% dan 30%, hal tersebut disebabkan karena seluruh variasi campuran tidak memenuhi parameter marshall. Kata kunci: Arang Tempurung Kelapa, Plastik LDPE, Parameter Marshall, Substitusi Sebagian Aspal   Abstract Plastic waste has now become a very common problem in the environment, Many reduction and prevention efforts have been carried out, but the results obtained are not in line with the growth and increasing use, especially plastics that are not managed properly. One of the efforts that must be made to reduce plastic waste is to utilize the viscoelasticity of the plastic and combined with coconut shell charcoal carbon and the material will be used as a substitute for part of the asphalt in the AC-WC layer. The purpose of this study was to determine the magnitude of variations in the mixture of LDPE plastic and coconut shell charcoal that can be used to meet marshall parameters in the AC-WC layer. The method used in this study is an experimental method that is deductive. The results of studies that have been carried out with LDPE plastic variation levels of 5%, 10%, 15% combined with coconut shell charcoal 5%, 10% and 15% results obtained from marshall testing for 10% variation, VIM and VFA are not eligible, 20% variation in VIM and VFA are not qualified and 30% variation only flow does not meet the specifications required by Bina Marga 2018 Revision II, so it can be concluded that LDPE plastic and coconut shell charcoal cannot be used as a partial substitution of asphalt at variations of 10%, 20% and 30%, this is because the entire variation of the mixture does not meet the parameters of marshalls. Keywords: Coconut Shell Charcoal, LDPE Plastic, Marshall Parameters, Partial Substitution

Abstract

This study aims to determine the effect of compaction temperature variation and graphene addition on Marshall parameters in AC-WC asphalt mixtures. The issues raised are premature damage to asphalt layers due to compaction temperatures that do not meet specifications and the lack of studies on the effect of graphene with compaction temperature variation on AC-WC. The materials used include coarse aggregate, fine aggregate, filler, Portland cement, 60/70 penetration asphalt, and graphene with variations of 0.01%–0.05% by weight of the mixture. The compaction temperatures tested were 110°C, 120°C, 130°C, 140°C, and 150°C. Testing was conducted in accordance with the 2018 Revised II General Specifications for Road Construction using the Marshall method. The results showed that adding 0.01% graphene at a compaction temperature of 140°C produced the best performance with a 19.55% increase in stability, yielding a stability value of 1711.367 kg. Density and MQ increased, while VMA, VIM, and flow decreased due to the addition of graphene, but still met the specification range. The decrease in these values demonstrates that graphene functions effectively in asphalt mixtures, improving porosity and strength compared to standard asphalt. At compaction temperatures of 110°C and 120°C, the VIM values exceeded the maximum limits of 9.67% and 7.05%, respectively. This increase could lead to excessive voids in the asphalt, making graphene a viable solution for asphalt construction.

Abstract

Highways play a strategic role in supporting economic development, so the quality of pavement materials (flexible pavement) must meet previously established quality standards. The Asphalt Concrete Wearing Course (AC-WC) layer, as the topmost layer of flexible pavement, is susceptible to damage caused by aging triggered by environmental conditions, particularly ambient temperature. Temperatures above 30°C are known to accelerate plastic deformation (rutting) and reduce pavement bearing capacity. The Meteorology, Climatology, and Geophysics Agency indicates that temperatures in Lhokseumawe City, North Aceh, range from 33.7–35.3°C with day-night fluctuations that could potentially accelerate the degradation of mechanical properties. This study aims to analyze the Marshall characteristics of AC-WC asphalt mixtures under ambient temperature conditions. The testing was conducted with varying exposure times of 0, 15, 30, 45, 60, 75, and 90 days at a minimum temperature of 23.90°C and a maximum temperature of 31.80°C, with an average humidity of 87.93%. The test results showed that the AC-WC asphalt mixture experienced a decrease in stability value of 21.37% and an increase in flow value of 36.36%, resulting in a decrease in the Marshall Quotient (MQ) value of 42.52%.

Abstract

Peningkatan suhu permukaan bumi dan kondisi iklim tropis yang fluktuatif dapat mempercepat penuaan aspal dan menurunkan performa perkerasan jalan, khususnya pada lapisan Asphalt Concrete–Wearing Course (AC-WC). Salah satu pendekatan untuk mengurangi dampak ini adalah penambahan graphene , nanomaterial yang mampu meningkatkan ikatan antara aspal dan agregat. Penelitian ini mengevaluasi pengaruh graphene sebesar 0,04% terhadap karakteristik Marshall campuran AC-WC yang dipaparkan pada ambient temperature dengan suhu rata-rata harian 27°C (23,9–31,8°C) dan kelembapan rata-rata 87,93%. Hasil pengujian menunjukkan bahwa campuran dengan graphene mempertahankan stabilitas lebih lama dibanding campuran normal, dengan peningkatan awal hingga 12,87%, sedangkan flow meningkat 15,68% secara bertahap dengan laju lebih rendah, dan Marshall quotient lebih tinggi pada awal hingga pertengahan pemaparan. Penambahan graphene secara keseluruhan memperlambat degradasi campuran AC-WC akibat fluktuasi suhu dan kelembapan tinggi, sehingga meningkatkan ketahanan dan ketegaran struktural campuran pada kondisi tropis.

Abstract

Progressive deterioration (e.g., corrosion) of the ageing bridge infrastructure is the main cause of structural deterioration and early failure of bridge especially in the marine environment. This paper presents a reliability-based approach for predicting the residual life of a bridge subjected to progressive deterioration. Specially, this study mainly focuses on developing a numerical approach for assessing the time-dependent probability of failure of a bridges. The results ofstudy show that the increase of progressive deterioration rates has a great impact on the decrease of bridge residual life. Further, the proposed realibility-based approach demonstrates the potential use for assessing probability of failure as well as predicting the residual life of bridges.

Abstract

Indonesia’s tropical climate, characterized by high temperatures and fluctuating humidity, presents a major challenge to the service life of pavements, as it accelerates asphalt aging and reduces the performance of the Asphalt Concrete–Wearing Course (AC-WC), the primary protective layer against traffic loads. This study investigates the effectiveness of Polyethylene Terephthalate (PET) waste as a modifying additive to enhance the resistance of AC-WC under ambient temperature conditions. Test specimens were prepared with 3% PET by asphalt weight and evaluated in accordance with Indonesian National Standards (SNI) and the 2018 Bina Marga General Specifications. The samples were exposed to temperatures of 23.77°C–31.11°C and an average humidity of 88.79% for periods of 0, 15, 30, 45, 60, 75, and 90 days, followed by stability, flow, and Marshall Quotient (MQ) testing. The results showed a stability increase of 13.74% at day 30, followed by a 16.81% decrease at day 90. Flow increased by an average of 19.70%, while MQ decreased by 15.75%. The mixture met the specification requirements for stability and MQ, but flow exceeded the limit after day 45. These findings confirm that PET can improve the early performance of AC-WC in tropical climates, although further optimization is required to control long-term plastic deformation.  Keywords: Polyethylene terephthalate, AC-WC, Marshall parameters, ambient temperature, tropical climate.
