Abstract

Abstrak. Parameter yang berhubungan dengan sifat mekanistik bahan, seperti modulus kekakuan sangat diperlukan baik untuk perencanaan tebal lapisan perkerasan jalan maupun untuk mengevaluasi kinerja campuran beraspal. Mengingat campuran beraspal merupakan material yang tidak bersifat elastis sempurna maka pemakaian istilah modulus elastis kurang tepat digunakan. Sebagai gantinya digunakan beberapa istilah seperti modulus resilien dan modulus dinamis. Tujuan dari penelitian ini adalah mengembangkan korelasi antara dua parameter modulus campuran beraspal tersebut, khususnya pada campuran SMA (Stone Matrix Asphalt). SMA yang digunakan dibedakan menjadi dua, yaitu dengan serat selulosa sebagai bahan penstabil dan dengan asbuton butir sebagai bahan penstabil. Berdasarkan hasil pengujian pengaliran aspal (draindown) terlihat asbotun butir dapat berfungsi sebagai penstabil SMA. Nilai modulus resilien dan modulus dinamis SMA akan berkurang apabila temperatur pengujian bertambah. Sementara dengan turunnya frekwensi pembebanan maka nilai modulus resilien dan modulus dinamis akan menurun juga. Korelasi antara modulus dinamis dengan modulus resilien pada kondisi frekwensi pembebanan dan temperatur yang sama cukup baik dengan R2 = 0,97 dimana nilai modulus dinamis sekitar 0,9 dari nilai modulus resilien. Abstract. Parameters that are related to the mechanistic properties of material, such as the modulus is an important factor both for thick layers design and for pavement performance evaluation. It is well known that most paving materials are not elastic but experience some permanent deformation after each load application and term of elastic modulus inappropriate to use. Another alternative that can be used is the terms such as dynamic modulus and resilient modulus. The purpose of this research is to develop a correlation between the two modulus parameters, especially for the SMA mix (Stone Matrix Asphalt). SMA is used can be divided into two, i.e. with cellulose fibers as a stabilizer and with granular asbuton as stabilizer. Based on the results of the draindown asphalt  testing, granular asbotun can serve as a stabilizer. The value of dynamic and resilient modulus will be reduced when the temperature testing increased. While the decrease of loading frequencies will be reduced the value of dynamic and resilient modulus. Correlation between the dynamic modulus and the resilient modulus quite well with R2 = 0.97 on the same conditions of temperature and loading frequency, where the dynamic modulus value about 0.9 the resilient modulus value.

Abstract

Asbuton is a natural rock asphalt that can be found on the island of Buton in Southeast Sulawesi province, has a large deposits but not yet well utilized. This research aims to find out the performance of asphalt mixtures AC-WC (Asphaltic Concrete Wearing Course) and HRS-WC (Hot Rolled Sheet Wearing Course) using bitumen results from full extraction of asbuton. The research was done by experimental methods through laboratory tests then its performance was compared to convensional mixtures using asphalt oil with penetration grade of 60. The results obtained showed that the bitumen of asbuton did not meet the specification of bitumen based on penetration grade. Characteristics of hot mixture asphalt using bitumen of asbuton showed better performance in terms of the Marshall stability namely 1871 kg higher than the convensional hotmixture of asphalt, with 1100 kg for AC-WC and 1241.9 kg compared with 1094 kg for HRS-WC. In addition, the results of deformation resistance tests showed asphalt mix with pure asbuton  more resistant to rutting shown by higher dynamic stability value namely 4200 track/mm compared with 492 track/mm for AC-WC and 2739 track/mm compared with 325 track/mm. The modulus resilient value of mix with pure asbuton is also higher at temperature of 25°C and relatively the sameat temperatures of 35°C and 45°C. While the resistance of  fatigue for AC-WC and HRS-WC on the test tensile strain of 150 µs were relatively the same as hotmix asphalt using asphalt oil penetration grade of 60, but on test of  a larger tensile strain has worse fatigue resistance, especially for AC-WC.

Abstract

Asphalt polymer has superior characteristics than conventional asphalt. Styrene Butadiene Styrene (SBS) is a polymer that has proven its performance in heavy traffic, but it must be imported and expensive. Crumb rubber have high potential to be used as an asphalt modifier. Asphalt modified crumb rubber has high viscosity and is not homogeneous, so that the utilization cannot be delayed. This reduces workability in the field. This study aims to obtain asphalt modified crumb rubber which is easier to use by adding materials that do not affect its performance. RejIRE is a low viscosity additive to restore the properties of bitumen on crumb rubber modified. Experiments were carried out by adding variations in RejIRE levels to crumb rubber modified asphalt to determine its characteristics. Continued investigation of the performance of hot paved mixtures for wearing courses compared to asphalt mixtures with Pen 60/70 asphalt and SBS modified asphalt mixtures. The result is the addition of 0.75% RejIRE on asphalt crumb rubber modification have high workability. Overall the performance of the mix with SBS modified asphalt is better, but the mixture of hot paved with modified asphalt crumb rubber has a resistance to permanent deformation superior to the other paved mixtures.

Abstract

ABSTRAK Deformasi permanen atau alur pada jejak roda merupakan jenis kerusakan yang banyak dijumpai dalam perkerasan jalan beraspal, danflow number umumnya digunakan sebagai parameter untuk melihat ketahanan terhadap deformasi permanen. Salah satu jenis perkerasan beraspal yang dikembangkan untuk lebih tahan terhadap alur adalah SMA (Stone Matrix Asphalt).  Tujuan dari studi ini adalah untuk mengembangkan model deformasi permanen pada campuran beraspal panas, khususnya pada campuran SMA.  Metodologi yang digunakan adalah metoda experimental  yang dimulai dengan pengujian bahan, pembuatan rancangan campuran dan selanjutnya pengujian flow number dengan variasi temperatur pengujian, jenis aspal, rongga udara dalam campuran serta gradasi campuran. Temperatur pengujian digunakan bervariasi dari 20, 35, 45 dan 56 0C.  Dua jenis aspal digunakan , yaitu aspal minyak pen 60/70 dan aspal minyak yang dimodifikasi dengan asbuton (aspal batu buton). Hasil studi menunjukkan nilai flow number (ketahanan terhadap alur) akan menurun jika temperatur dan void dalam campuran meningkat, dan flow number akan meningkat jika filler bertambah dalam rentang tertentu. Flow number juga akan meningkat dengan meningkatnya viskositas aspal.  Pengembangan model deformasi permanen telah dikembangkan dengan jumlah data sebanyak 32 buah.  Persamaan tersebut  dibatasi untuk material SMA dengan menggunakan gradasi AASHTO dan untuk beban axial 87 psi (unconfined test). Apabila dibandingkan dengan model deformasi permanen yang telah dikembangkan Rodezno dkk (2010), model ini menghasilkan nilai flow number yang lebih rendah sebagai akibat dari adanya perbedaan dalam pengkondisian contoh uji. Kata kunci: deformasi permanen, flow number,  stone matrix asphalt, asbuton  ABSTRACT Rutting has been considered the most serious distress in flexible pavement, and flow number is an explanatory index for the evaluation of the rutting potential of asphalt mixtures.  One type of asphalt paving are developed to be more resistant to rutting is the SMA (Stone Matrix Asphalt),.  The objective of this study was to develop permanent deformation model for hotmixtures, especially for SMA mix. The methodology used in this study is experimental method, its start from material testing, perform design mix and flow number test in some defferent variables such as  testing temperature, binder type, mix volumetric and  mix grading.  The temperature used vary from 20, 35, 45 and 56 0C. Two different binder type was used, i.e. pure petroleum bitumen 60/70 pen grade and  pure petroleum bitumen modified  by granular Buton rock asphalt (asbuton).  The flow number (rutting resistance) of SMA mixture observed in ths study were decreases when the temperature and void in mix increase, and  the flow number will increase if  the increased filler in a certain boundary.  Flow number will also increase with increasing viscosity of asphalt.  The development of permanent deformation model has been developed with the amount of data as much as 32 data.  The equation should be limited to the SMA mix by using a gradation of AASHTO standard  and axial stress for testing of 87 psi (unconfined test).When compared to the permanent deformation modes that have been developed by Rodezno et al (2010), the model generates value of flow number is lower as a result of the differences in  conditioning of the sample. Keywords: permanent deformation, flow number,stone matrix asphalt, asbuton
