Kerusakan jalan akhir-akhir ini semakin sering terjadi pada lapis perkerasan jalan  berupa  retak-retak, terkelupasnya agregat, lubang-lubang hingga amblasnya perkerasan jalan. Hal  ini dapat terjadi disebabkan: tingginya temperatur permukaan jalan, intensitas curah hujan yang sulit diprediksi serta beban lalulintas yang semakin hari semakin bertambah. Aspal modifikasi dibuat dengan menambahkan bahan yang bersifat elastomer seperti karet alam, maupun karet sintetis dan bahan plastik, sehingga dapat meningkatkan sifat-sifat fisik dari aspal seperti: elastisitas, ketahanan terhadap temperatur dan dapat meningkatkan stabilitas pada campuran aspal beton. Uji coba pemanfaatan limbah plastik sebagai bahan pengganti aspal telah dilaksanakan pada jalan nasional di Indonesia maupun di Manca negara, hal ini menimbulkan pro dan kontra dari  aktivis lingkungan. Namun menurut beberapa sumber menyatakan bahwa aspal modifikasi ini bisa bertahan di suhu ekstrem (- 4,5oC hingga  80oC). Berdasarkan permasalahan di atas akan diteliti, berapa persen limbah plastik HDPE yang efektif ditambahkan pada aspal modifikasi untuk campuran Laston (AC-BC) agar tahan terhadap cuaca ekstrem.  Pengujian dilakukan pada 75 benda uji dengan kadar aspal optimum 5,4 % dan limbah plastik HDPE bervariasi 0%; 2%; 4%; 6% dan 8% terhadap berat aspal. Untuk mengetahui pengaruh suhu dari campuran Laston, sebelum dilakukan Marshall Test, terlebih dahulu benda uji direndam pada suhu 60oC; 70oC; 80oC selama 30 menit dan 60oC  selama 24 jam. Berdasarkan Spesifikasi Lapis Perkerasan aspal (Bina Marga revisi 3, 2010), limbah plastik HDPE yang dapat ditambahkan pada campuran LASTON (AC-BC)  hanya   2-4 % terhadap berat aspal, yang memenuhi nilai karakteristik Marshall dan tahan terhadap cuaca ekstrem.Kata kunci: Limbah plastik HDPE, aspal beton, cuaca ekstrem Recent road damage is increasingly common in pavement layers in the form of cracks, peeling aggregates, holes, until the pavement is inundated. This can happen because: the high surface temperature of the road, the intensity of rainfall that is difficult to predict and the traffic load that increasingly day. Asphalt modification is made by adding elastomeric materials such as natural rubber, as well as synthetic rubber and plastic materials, so as to enhance the physical properties of asphalt such as: elasticity, resistance to temperature; and can increase the stability of concrete asphalt mixture. Plastic waste utilization trials as asphalt substitute have been implemented on national roads in Indonesia as well as in many countries, leading to the pros and cons of environmental activists. However, some sources have stated that this modified asphalt can survive in extreme temperatures (- 4.5°C to 80°C). However, according to some sources stated that this modified asphalt can survive in extreme temperatures (- 4.5°C to 80°C). Based on the above issues, it was examined how much the effective percentage of HDPE plastic waste was added to modified asphalt for the Laston mixture (AC-BC) which was resistant to extreme weather. The test was conducted on 75 specimens with optimum asphalt content of 5.4% and HDPE plastic waste varied 0%; 2%; 4%; 6% and 8% to asphalt weight. To determine the effect of temperature from the mixture of Laston, before the Marshall Test conducted, the first specimen is immersed at 60°C; 70°C; 80°C for 30 minutes and 60°C for 24 hours. Based on Asphalt Pavement Specification (Bina Marga Revision 3, 2010), the HDPE plastic waste that can be added to the LASTON (AC-BC) mixture is only 2-4% of the asphalt weight, which meets the Marshall characteristics and is resistant to extreme weather.Key words: HDPE plastic waste, concrete asphalt, extreme weather

Several factors that can affect road damage are excessive traffic load, temperature (weather), water, and pavement construction that does not meet the technical requirements. The durability of an asphalt mixture is the resistance of the mixture to the effects of water, water vapor, and temperature. A mixture with a high durability value provides a good mix quality and long-term use. The purpose of this study was to determine the durability of the AC-BC mixture using Mount Baba stone. The general specifications of Bina Marga in 2018 are the reference in this study. By using the standard Marshall test method, the results obtained through the Marshall AC-BC mixture immersion test with a duration of immersion time of 0.5 hours, 12 hours, 24 hours, 36 hours, 48 hours, 60 hours with a durability value of 95.49% - 86.99%. The increase in immersion time causes a decrease in the durability of the mixture.

An asphalt modified by epoxy resin and rubber has the following improved properties: the softening point is 70 , elastic recovery rate is 80%, and kinematic viscosity at 175 is 2879.1mm2 /s. In order to solve the early curing in the process of mixing, storage and transportation, methyl hexahydrophthalic anhydride(MHHPA) was used as the curing agent. A reflective cracking caused by traffic load simulation test was established with the objective to compare the propagation speed of reflective crack of three different structure asphalt mixture samples. The results showed that the sample with epoxy resin and rubber used as stress-absorbing layer can obviously delay reflective cracking, improve the pavement performance and prolong the road life. Furthermore, the results of Marshall test, immersion Marshall test and Rutting test were consistent with the results of the reflective crack simulation test.

Polymer Modified Asphalt

Asphalt Concrete mixture of polymer modification are used to reduce the damage early and increasing the durability of pavement to various damage such as permanent deformation, cracking due to temperature changes, fatigue During this process the polymer asphalt mixing using Hot Mix Asphalt / HMA. In accordance with the name and nature of hot mix asphalt, require high enough heating temperature on the Asphalt Mixing Plant (AMP), and also requires a high temperature compaction. As a result, it takes quite a lot of fuel so produced a large exhaust emissions. Emissions generated during the mixing process and compaction of HMA is a challenge for the environment. Some countries have developed a method of asphalt mixture to overcome this by using Warm Mix Asphalt technology. Warm Mix Asphalt is the technology of mixing and compaction temperatures of asphalt mixtures using mixing and compaction temperatures lower than Hot Mix Asphalt. Decreasing the mixing and compaction temperatures by adding additives to the asphalt mixture. Types of additives that have been widely used and developed for Warm Mix Asphalt them is the use of synthetic zeolites with various trademarks such as Aspha-min (R), Sasobit(R) dan Advera(R). In this paper the synthetic zeolite will be replaced by natural zeolite as an additive to be mixed with a mixture of Polymer Modified Asphalt Concrete. This study uses laboratory testing, using aggregate materials from Subang, West Java, Asphalt Elastomer Polymers, natural zeolite mineral mordenite sourced from Bayat, Central Java, Indonesia.

Flexible pavements deteriorate and crack with time due to the frequent traffic load imposed upon it. Many studies have been done to predict the effects of frequent traffic load and environmental conditions on pavements in the effort to find the best pavement design which resist deterioration and ensure longer pavement service time. This study investigates the effect of mixing asphalt with varying percentages of nano calcium carbonate (CaCO3), namely 0, 2, 4, and 6 %. The mixtures were designed based on the Superpave mix design criteria. Investigation was done using several tests, namely resilient modulus, indirect tensile strength, moisture susceptibility, and dynamic modulus tests. Samples were subjected to aging to determine their resilient modulus. The results of the investigation show that resilient modulus and indirect tensile strength increased when higher percentages of nanoparticles were added to asphalt mixture, with improvement of 138 and 48.18% respectively. Modified binders showed up to 17% improvement in moisture susceptibility comparison to base asphalt mixture, while the result of dynamic modulus test showed that the stiffness of modified asphalt increased 76.69%. The investigation also found that adding 6% CaCO3 nanoparticles to asphalt produced modified asphalt with the best performance. In addition, the results show that the modified asphalt with CaCO3 is suitable for hot and humid regions (tropical countries) in the field of highways construction, as the modifier was able to mitigate the influences of high-temperature rutting and moisture damage.
