Abstract

The increase in road traffic during the last two decades in combination with an insufficient degree of maintenance due to shortage in funds has caused an accelerated and continuous deterioration of the road network. To alleviate this process, several types of measures may be effective, e.g., securing funds for maintenance, improved roadway design, use of better quality of materials and the use of more effective construction methods. Aspalt can also be modified by adding different types of additive. One of these additives is the polymers such as Polyethylene (PE) and  High Density Polyethylene (HDPE).  The addition of polymers typically increases the stiffness of the aspalt  and improves its temperaturesusceptibility. Increased stiffness improves the rutting resistance of the mixture in hot climates and allows the use of relatively softer base aspalt, which in turn,provides better low temperature performance. This study was conducted to determine the effect of utilizing Polyethylene (PE) and High Density Polyethylene (HDPE) as a mixture of thin layer of asphalt concrete in wearing course (Lataston_WC) using Marshall design parameters. The parameters assessed are the stability, flow,  the percentage of air void in the mixture (VIM), the percentage of void in the mineral aggregate (VMA), the percentage of void filled with aspalt (VFA), and Marshall Quotient (MQ). Marshall samplers prepared with the PE and HDPE modified aspalt binder provide the specification limits. The percentage of  PE and HDPE as asphalt mixture is 0%, 2%, 4% and 6% by weight of the asphalt. The result of Marshall test showed that the value of stability, flow and VFA have tendencey to increase with incresing of percentage of PE and HDPE. But, the value of VIM, VMA and MQ have tendency to decrease with  incresing of percentage of PE and HDPE. It can be seen that effect of addition HDPE on aspalt mixture provide the value of Marshall characteriscs are better than aspalt mixture with PE

Abstract

In Indonesia, many roads have been damaged especially on flexible pavement design. There are caused by the high of traffic volume, extreme climate changes, the bad subgrade quality and the lack of quality of pavement material. The aim of this research is to analysis of the pavement quality of the road using KENPAVE program. Case study research is on Karangmojo– Semin road,  Sta. (0 + 000) to Sta. (4 + 050), Gunung Kidul,  D.I Yogyakarta. The program can give the value of stress and strain on the road due to traffic load. The response of  stress and strain caused by fatigue cracking and rutting from KENPAVE output with pavement thickness analysis using Bina Marga 1987method are 0,000408 and 0,00138, respectively and using AASHTO 1993 method the fatigue crackingand rutting are 0,000322 and 0,00134, respectively. The flexible pavement design using method of Bina Marga 1987 and AASHTO 1993 produce the amount of load repetition with a traffic load plan is greater than the number of repetition load plan, so the road will have possibilities of  fatigue cracking and rutting damage before the design life reached.

Abstract

There are four main factors causing traffic accident : human factor, vehicle factor, road factor and environment factor. Accident data from Poltabes Yogyakarata in 2007 showed that road factor causes accident is 2.45%. In effort to achieve traffic safety, the infrastructure must be considered in the first list. This research is dealing with “Utilizing High Density Polyethylene (HDPE) Synthetic Aggregate as a Chip Sealing Material in Improving Skid Resistance”. The purpose of this research is to understand the effect of chip sealing using HDPE synthetic aggregate on the skid resistance, so that the surface pavement can provide good service for traffic and road users and the quantity of accident can be reduced. In this research the skid resistance was  measured using British Pendulum Tester such that the its skid resistance is also called British Pendulum Number (BPN). BPN is a measured based on 3 variations of aggregate weight being spreaded, that are 240 grams, 271 grams and 304 grams. The result of BPN will be correlated with the wet accident ratio, friction coefficient and stopping distance. The BPN values being obtained are 55.96, 55.6 and 53.4, respectively. The BPN was found to increase with the increase of aggregate weight in chip seal mixture. It was revealed that BPN with chip sealing using HDPE could be increased by approximately 10 % in comparison with that without chip sealing. In addition, chip sealing using HDPE can reduce the accident ratio by 47.32 %, improve the traffic safety by 47.32 %, and shorten the stopping distance. The greater friction coefficient the lower stopping distance, and the lower stopping distance the better traffic safety.

Abstract

The overlay is the addition of pavement layer thickness which is placed on the existing pavement construction to increase the strength and to serve the planned traffic during the specified period. This research is a case study conducted in Yogyakarta-Batas Kota Bantul road using Bina Marga and Asphalt Institute method. Although a new highway is upgraded, it is possible that the road construction will be damaged in a relatively short time. With this consideration, it is necessary to evaluate the thickness of pavement overlay. The length of the evaluated road segment was divided into three (3) sections, namely Segment I (Sta 4+000 - Sta 5+800), Segment II (Sta 6+000 - Sta 7+800) and Segment III (Sta 8+000 - Sta 10+320) to get the pavement thickness uniformity level. Based on the results of the analysis with the Bina Marga method (Pd T-05-2005-B), the thickness of the layers was added for segment I (6.942 cm), segment II (6.618 cm), and segment III (6.055 cm). While in the calculation using Asphalt Institute (MS-17) method, it was obtained that there was additional layer thickness 3.556 cm in segment I, 3.048 cm in segment II, and 2.790 cm segment III. The result of overlay thickness correction of Bina Marga method using AASHTO equivalent shows the number of 2.794 cm segment I, 2.470 cm in segment II, and 1.907 cm in segment III.

Abstract

Aspal dapat dimodifikasi dengan menambahkan berbagai jenis aditif. Salah satu aditif yang biasa digunakan adalah berupa polimer seperti Polypropilene (PP) dan High Density Polyethylene (HDPE). Penambahan polimer biasanya meningkatkan kekakuan aspal dan meningkatkan kerentanan suhu. Peningkatan kekakuan aspal akan meningkatkan ketahanan campuran terhadap rutting dari suhu dan cuaca yang  panas. Penelitian ini dilakukan untuk mengetahui pengaruh pemanfaatkan limbah plastik PP dan HDPE sebagai campuran pada  beton aspal (Laston_WC) dengan menggunakan parameter Marshall. Parameter Marshall yang digunakan yaitu stabilitas, flow, VIM, VMA, VFA dan MQ. Prosentase PP dan HDPE yang digunakan sebagai campuran aspal sebesar 0%, 2%, 4% dan 6% dari berat aspal yang digunakan. Hasil uji Marshall menunjukkan bahwa nilai stabilitas, flow, VFA dan MQ memiliki kecenderungan mengalami peningkatan dengan bertambahnya  prosentase kadar PP dan HDPE yang digunakan. Tetapi, nilai VIM dan VMA memiliki kecenderungan menurun dengan bertambahnya prosentase PP dan HDPE. Hal ini dapat dilihat bahwa pengaruh penambahan PP pada campuran aspal beton akan memberikan nilai karakterisk Marshall yang lebih baik dari campuran aspal beton dengan HDPE.

Abstract

Aspal merupakan bahan yang digunakan sebagai perekat pada perkerasan lentur. Pada umumnya perkerasan lentur melimpaskan air hujan hanya dipermukaan perkerasan saja, akibatnya sering terjadi genangan yang membahayakan pengendara yang melintas. Salah satu alternatif untuk mengatasi permasalahan ini adalah dengan menggunakan teknologi aspal porus. Aspal porus merupakan perkerasan aspal dengan rongga be rkisar 11%-28% sehingga bisa mencegah genangan air saat terjadi hujan. Penelitian ini mengkaji pengaruh lateks sebagai bahan pengganti sebagian aspal pada perkerasan aspal porus dengan variasi kadar lateks 0%, 1%, 3%, 5% dan 7%. Spesifikasi yang digunakan adalah spesifikasi AAPA (1997). Nilai KAO didapat sebesar 5,75%, pada pengujian aspal dengan campuran lateks didapat nilai penetrasi tertinggi adalah 63,9, kehilangan berat minyak 0,2576, nilai daktalitas, titik lembek mengalami kenaikan seiring penambahan kadar lateks. Pada pengujian aspal porus dengan variasi kadar lateks diapat nilai density dan VFA mengalami penurunan seiring bertambahnya kadar lateks, nilai VMA, flow dan VIM cenderung mengalami peningkatan seiring bertambahnya kadar lateks, nilai stabilitas marshall tertinggi 592,04 kg, nilai Marshall Quotient 132,76 kg/mm, nilai Asphalt Flow Down 0,21% dan nilai Cantabro Loss adalah 14,61%.
