MIXTURE USE INFLUENCE LIQUID ASBUTON TOWARDS ASPHALT POROUS IN VALUE FLOW AND BINDER DRAIN DOWN M. gani 1, H. Arfan, M. Mangussa 2 ABSTRACT : Porous Asphalt asphalt mixture that being developed for construction wearing course. this layer uses opened gradation (open graded) that is spreaded on waterproof asphalt covering. mixture is dominated by coarse aggregate, to get pore enough tall so that got permeability porous asphalt tall, where is permeability memfungsikan to subsurface drain. in indonesia the increasing of national asphalt need can not be filled asphalt production in country, so that half from total still must be imported. one of [the] alternative that can considering to decrease asphalt import all at once repair bituminous mixture performance make use liquid asbuton. the troubleshoot how far use liquid asbuton can subsidize asphalt performance porus remember in liquid asbuton contain mineral that can clog existing pore. to test water flow time in asphalt pore porus, done watchfulness at laboratory with make test thing has used japanese gradation as much as 60 fruit with 5 asphalt degree variations to has got optimum asphalt degree value and as much as 12 fruit by using optimum asphalt degree values. from asphalt characteristics testing result porus by using optimum asphalt degree value is got value cantabro 13,01%, porosity value 15,81%, flow speed value 0,143 cm/dtk, value binder drain-down 0,08% and stability value marshall 952,92 kg. Keyword: asphalt porus, Liquid Asbuton, value flow, binder drain down, japanese gradation FOREWORD Along construction technology development perkerasan road, design perkerasan to increase style scours especially to prevent aquaplaning at runway airfield, (ministry of defence, 1998). moment applied to perkerasan highway, known with previous macadam and then day is known with the title porous asphalt/pa (british standards institutions 2001). asphalt mixture porus be new generation in perkerasan bent, permit water penetrates into flake (wearing course) vertically and horizontal. this layer uses opened gradation (open graded) that is spreaded above waterproof asphalt covering. asphalt covering porus this effectively can give welfare level more, especially at rain time so that doesn't happen aquaplaning so that produce surface coarseness harsher, and can decrease noise (noise reduction). has deposit asbuton that be nature materials found at island buton provinsi celebes south east, asbuton not yet can be maked use in an optimal fashion because still to lose to compete with oil asphalt, this matter is caused because 1 2 Lecturer, civil technique direction, university hasanuddin, makassar 90245, indonesia Student university, civil technique direction, university hasanuddin, makassar 90245, indonesia 2
asbuton still necessary cleansing beforehand before maked use for mixture perkerasan. besides degree bitumen found on asbuton low relative, that is vary between 15% - 45% from heavy total. (tjitjik, s sastramihardja, 1998). METHODOLOGY method eksperimental serious (trueexperimental research) used in this watchfulness with holds effort activity at where is asphalt porus produced by using aggregate kind with opened gradation system (open granded). aggregate is got from river bili district parangloe result stone crusher celebes province south, while liquid asbuton taken from testing area laboratory and celebes province clan build official technology development south later on is done observation towards values karaktristik ingredient at university transportation engineer laboratory hasanuddin. next made test thing with 5 asphalt degree variations to get optimum asphalt degree value, after got optimum asphalt degree value is done testing marshall, cantabro, binder drain-down, and flow speed. ingredients that used in asphalt mixture porus beforehand tested characteristics from each coarse aggregate good ingredient, soft aggregate, filler also testing towards liquid asbuton where does testing method threaten in sni and this testing is done at laboratory. every asphalt degree variation is made 3 test things (total 72 test things).

Hasil pengujian marshall CONCLUSION AND SUGGESTION Conclusion Based on data analysis that got in this watchfulness, so inferential as follows: 1. from asphalt characteristics testing analysis result porus that use open graded japanese gradation with liquid asbuton upon which binder can fulfil spesification parameter for structure perkerasan bent. 2. optimum asphalt degree value that got from connection graph analysis result several asphalt performance parameters porus (cantabro, porosity, permeability, binder drain down, stability marshall, flow, and marshall quotient) 8,6 %. 3. water flow time analysis result in asphalt pore porus flow speed testing uses optimum asphalt degree value is got result that is 0,143 cm/dtk. this show asphalt porus use japanese gradation and liquid asbuton upon which binder can channel water well because fulfil spesification parameter minimum 0,1 cm/dtk. Suggestion Based on watchfulness result, proposed several suggestions as follows: 1. Necessary be done test variation try watchfulness hit water flow time insides asphalt pore porus furthermore again so that can detect until how far asphalt ability porus if flowed water and in the event of gagging. 2. Necessary done test tries asphalt use application porus to ruas - ruas road in indonesia especially in region with curah rain with tall accident level. DAFTAR PUSTAKA Affan, M.
