Abstract
commonly said the ideal gradation. But they are not find of the ideal gradation, because they are not have services from stone crushe in the regional area. The solve of the problem could be used of aggregate gradations as almost reached in the lower limit and or upper limit of the specification, the consequency would be have decrease of the quality of the mixture. In the survey of the decrease of quality is show durability and workability are in the asphalt mix implementation. So, the mix design for research is Split Mastic Asphalt mixture (SMA). This research uses optimum asphalt content of 7.06% as base of secondary data and implemented in Laboratory matherial for pavement of Muhammadiyah University of Surakarta. The sample of the specimen had been made to be submers with 5(five) variation of time ,e.a. 24 hours, 96 hours, 168 hours, 240 hours and 336 hours. The Marshall test would be executed after reached of the times,than the durability analysis are be consist of perhitungan Indeks Kekuatan Sisa (IKS), Indeks Durabilitas Pertama (IDP) dan Indeks Durabilitas Kedua (IDK). The magnitude of the value of workability in terms of the value of density factor that decreased from the middle boundary gradation to the gradation of the lower limit. The result of the research “Analysis of Workability and Durability Material Split Mastic Asphalt (SMA) Grading 0/11 in The Range of The Limits gradation, The Bottom gradation and The Central Limit gradation” shows that 96 hours immersion IKS value is 93.60% for the lower limit gradation, 96.91% for the middle border gradation and 91.52% for the upper limit gradation. From the data seen still meet the minimum requirement of 90% which means the mixture is quite durable based on the value of IKS. IDP value increased until the duration of 336 hours of flooding reached 0.257% for the lower boundary gradation, 0.553% for the middle boundary gradient and 0.375% for the upper limit of all values are still eligible ie <1% so the mixture is said to be durable based on the value of IDP. Total IDK value for 336 hours was 5.38% for lower boundary gradient, 8.60% for middle boundary gradation and 6.27% for upper limit gradient with tolerable limit of each grading of 94.06 hours for lower grade gradation, 98.22 hours for middle boundary gradation, 91.90 hours for upper limit gradation. This indicates that the mixture continues to experience power loss for 336 hours of immersion. The amount of mixed density factor is 105.41% for upper limit gradation, 107.54% for middle border gradation and 94.91% for lower limit gradation.
