AbstrakPada campuran perkerasan aspal dibutuhkan bahan pengisi (filler) untuk mendukung kinerja konstruksi perkerasan jalan agar dapat menahan beban lalu lintas. Berbagai jenis filler telah banyak digunakan antara lain abu batu, semen portland dan lain-lain. Namun keterbatasan sumber daya alam mendorong upaya pemanfaatan bahan-bahan buangan dalam konstruksi perkerasan jalan. Pada penelitian ini, digunakan limbah kaca sebagai filler pada campuran perkerasan aspal. Penelitian ini bertujuan untuk mengetahui prosentase filler limbah kaca yang paling optimum dan pengaruhnya terhadap kinerja campuran. Kinerja tersebut diukur melalui pengujian stabilitas, flow, Marshall Quotient, rongga dalam campuran, rongga di antara mineral agregat, rongga terisi aspal, Marshall immersion, tegangan tarik tidak langsung dan Cantabro loss. Hasil penelitian menunjukkan bahwa penggunaan limbah kaca dengan proporsi 75% terhadap berat filler meningkatkan stabilitas dan kekakuan campuran sehingga lebih mampu untuk menerima pembebanan. Campuran dengan proporsi 75% filler limbah kaca menghasilkan nilai VIM dan VMA lebih kecil serta nilai VFB lebih besar yang mengindikasikan bahwa campuran memiliki daya ikat dan sifat saling mengunci yang kuat sehingga menghasilkan rongga lebih kecil serta selimut aspal lebih tebal. Berdasarkan hasil uji Marshall immersion dan Cantabro loss, campuran dengan proporsi tersebut lebih tahan terhadap rendaman air sehingga memiliki durabilitas lebih tinggi serta lebih tahan terhadap potensi disintegrasi. AbstractFiller is required in the asphalt concrete mixture to support the performance of pavement construction in order to withstand the traffic load. Various types of filler has been widely used, such as stone ash, portland cement and others. However, because of limitation of available natural resources, there has been a significant increase in the demand for using waste materials in pavement construction. In this study, waste glass was used as filler in asphalt concrete mixture. This study aims to determine the optimum percentage of waste glass filler and evaluate its effect on the performance of asphalt concrete mixtures. The performance was measured in term of stability, flow, Marshall Quotient, voids in mix, voids in the mineral aggregate, voids filled with bitumen, Marshall immersion, indirect tensile strength and Cantabro loss. The results showed that using the percentage of waste glass of 75% by weight of filler increased stability and stiffness so that the mixture became stronger to withstand the load. The mixtures with a proportion of 75% waste glass filler have smaller VIM and VMA values and a larger VFB. It is indicated that the mixtures have strong bonding and interlocking properties resulting in smaller voids and thicker asphalt binder film thickness. Based on the results test of Marshall immersion and Cantabro loss, the mixtures with stated proportion more resistant to water immersion, resulting in higher durability and greater resistance to potency of disintegration.

Asphalt concrete wearing course is laid on the top of road pavement so that directly exposed to ultra violet light and other environment impact. The higher temperature at the pavement surface and exposure to atmospheric oxygen accelerated aging cause asphalt to stiffen and become brittle. This aging result decrease the binding of asphalt and aggregate leads various damage of pavement. The aged asphalt rejuvenated and recycled with rejuvenating agent has been developed to reduce the use of virgin material for road maintenance. This article aims to review durability of asphalt concrete wearing course using waste cooking oil, epoxy resin, kerosene and waste engine oil as asphalt rejuvenators. Aging asphalt was prepared by heating in an oven at 85 oC for 120 hours (long term oven aging). Durability was assessed from the value of Marshall immersion which represent the resistance of asphalt mixture at water immersion. Relation between Marshall immersion and voids in mix (VIM), voids in the mineral aggregate (VMA), voids filled with bitumen (VFB) and density are also evaluated. From the analysis, it can be concluded that the use of waste cooking oil, epoxy resin, kerosene and waste engine oil as asphalt rejuvenators increase the durability of asphalt mixture containing the aged asphalt.

Sifat volumetrik campuran pada laston merupakan salah satu faktor yang menentukan durabilitas (keawetan) lapis perkerasan jalan. Untuk meningkatkan keawetan lapis perkerasan jalan dan mengurangi dampak negatif terhadap lingkungan dapat dilakukan antara lain melalui modifikasi aspal dengan getah pinus dan limbah styrofoam. Tulisan ini bertujuan untuk mengkaji sifat volumetrik campuran laston menggunakan aspal modifikasi getah pinus dan limbah styrofoam tersebut. Sifat volumetrik campuran laston yang dikaji adalah rongga dalam campuran, rongga di antara mineral agregat, rongga terselimuti aspal, density dan bulk specific gravity. Pada penelitian ini digunakan agregat bergradasi rapat yang dicampur dengan aspal modifikasi pada suhu 155 oC dan dipadatkan 75 kali pada kedua sisinya. Pada seluruh benda uji, prosentase limbah styrofoam yang digunakan adalah 6% sedangkan getah pinus sebesar 0%, 1%, 2% dan 3% terhadap berat aspal modifikasi. Hasil penelitian menunjukkan bahwa campuran laston yang menggunakan aspal modifikasi getah pinus menghasilkan nilai VFB, density dan bulk specific gravity lebih besar serta nilai VIM dan VMA lebih kecil dibandingkan dengan campuran yang menggunakan aspal modifikasi limbah styrofoam. Dengan nilai VIM dan VMA lebih kecil, campuran yang menggunakan aspal modifikasi getah pinus menghasilkan daya ikat lebih kuat sehingga memiliki durabilitas lebih tinggi. Ditinjau dari persyaratan laston sebagai lapis aus pada perkerasan jalan, penggunaan getah pinus dan limbah styrofoam sebagai modifier aspal memenuhi persyaratan volumetrik campuran. Volumetric properties of asphalt concrete is important factor to determine the durability of road pavement. Improvement the durability of road pavement and reducing negative impact of the environment can be done by using modified asphalt. This article aims to know the volumetric properties of hot mix asphalt using pine resin and waste styrofoam as asphalt modifier. The volumetric properties include voids in mix, voids in the mineral aggregate, voids filled with bitumen, density and bulk specific gravity. In this study, a continuously graded aggregate was used and mixed with modified asphalt at 155 oC and compacted with 75 blows on both sides. The percentage of waste styrofoam was 6% whereas the percentages of pine resin where 0%, 1%, 2% and 3% by weight of modified asphalt. From the analysis, it can be concluded that asphalt concrete containing pine resin as modifier strengthen the binding between asphalt and agregate, due to increasing value of voids filled with bitumen (VFB), density and bulk specific gravity. Durability of asphalt concrete using pine resin as modifier was higher than that of asphalt concrete using waste styrofoam because of decreasing value of voids in mix (VIM) and voids in the mineral aggregate (VMA). Based on the specification of asphalt concrete wearing course, the use of pine resin and waste styrofoam as asphalt modifier has fulfilled volumetric properties requirements.

Road damage is caused by several factors, namely: unstable subgrade, climate, poor drainage system, materials, and work processes that do not meet the requirements. Besides that, vehicle traffic loads have a greater effect. Normal traffic load can maintain life as design. Problems arise when many vehicles pass with loads that exceed the required load limit. This will reduce the service life. Therefore, strict supervision of the maximum load at the weighbridge requires special attention. Especially if the road is an arterial road that is dominated by freight vehicles. The effect of decreasing pavement service life due to overloading can be done by comparing the service life with normal load and overload. The research was conducted on a national road section, namely Jalan Raya Ahmad Yani, located in Narmada, West Lombok Regency. The analysis was carried out on secondary data, namely the number of vehicles entering the weighbridge and daily traffic on average in 2018 and 2019. The results of the analysis are the number of equivalent axle loads and the Vehicle Damage Factor (VDF) on each type of vehicle with normal loads or more using the Bina Marga Method. Furthermore, the design life reduction analysis is carried out based on the cumulative results of Equivalent Standard Axle Load (ESAL) under normal load and overload conditions. The results of the analysis show that the equivalent value or VDF of normal load vehicles is 385120.1870 and VDF overload is 643207.3800 so that the percentage increase in VDF value is 67.01% and there is a decrease in age of 3.1 years, with the planned age of 10 years.
