Abstract : Endurance of asphalt concrete pavement on traffic load and temperature depends on the type and composition of aggregates, asphalt and filler used. Many attempts have been made to improve the quality of the mixture, such as using modified asphalt. Modified asphalt made by mixing asphalt pen. 60/70 with addition material. In this research, we used crumb rubber as an aggregate substitute material on AC-BC mixture. This study aims to determine the influence of additional substitution of used crumb rubber. The first step of the research is to find the optimum asphalt content (OAC), then add the crumb rubber as an aggregate substitute material from 0%, 1%, 2%, 3%, 4% and 5% to the weight of the mixture. The results showed that the percentage of crumb rubber influenced Marshall parameters value, especially the value of stability, VIM and VMA at 5.285% asphalt content. The highest stability value was found in the mixture of 2% crumb rubber is 1128.48 Kg. The highest VIM value is in the 5% mixture of the used crumb rubber is 16.94%. The highest VMA value is in the 5% mixture of the used crumb rubber is 27.88% and the highest flow value is in the 5% crumb rubber mixture of 4.97 mm. However, in MQ value increase and decrease that happened very big. No big changes in the density and VFA values for all substitutions of crumb rubber. For the durability value of AC-BC mixture with crumb rubber variation 90% requirement only on crumb rubber 1%.Abstrak: Ketahanan perkerasan beton aspal terhadap beban lalulintas dan temperatur sangat tergantung pada jenis dan komposisi agregat, aspal serta filler yang digunakan. Banyak usaha telah dilakukan untuk meningkatkan kualitas campuran, salah satunya dengan menggunakan aspal modifikasi. Aspal modifikasi dibuat dengan mencampur aspal pen. 60/70 dengan bahan tambah. Pada penelitian ini bahan tambah yang digunakan adalah parutan ban karet bekas sebagai bahan pengganti agregat pada campuran AC-BC. Penelitian ini bertujuan untuk mengetahui pengaruh substitusi tambahan ban karet bekas sebagai bahan pengganti agregat. Tahapan awal penelitian adalah mencari Kadar Aspal Optimum (KAO), kemudian dilakukan penambahan parutan ban karet bekas sebagai bahan pengganti agregat mulai dari 0%, 1%, 2%, 3%, 4% dan 5% terhadap berat campuran. Dari hasil penelitian menunjukkan penambahan persentase parutan ban bekas mempengaruhi nilai parameter Marshall, terutama nilai stabilitas, VIM dan VMA pada kadar aspal 5,285%. Nilai stabilitas tertinggi didapat pada campuran 2% parutan ban bekas yaitu 1128,48 Kg. Nilai VIM tertinggi ada pada campuran 5% parutan ban bekas yaitu 16,94%. Nilai VMA tertinggi ada pada campuran 5% parutan ban bekas yaitu 27,88% dan nilai flow tertinggi ada pada campuran 5% parutan ban bekas yaitu 4,97 mm. Namun pada nilai MQ kenaikan dan penurunan yang terjadi sangat besar. Nilai Density dan VFA tidak terjadi perubahan yang besar untuk semua substitusi variasi parutan ban. Untuk nilai durabilitas campuran AC-BC dengan variasi parutan ban yang memenuhi persyaratan 90% hanya pada pemakaian parutan ban 1%.

Although there is a large population in the limited space of metropolitan areas in Taiwan, but many manholes are often set on the pavement, which impact the quality of the pavement service and lead to public complaints. In recent years, the manholes have been gradually buried under the pavement on policy, so as to improve administration performance of government. The construction quality at the location of manhole is not easy to control, and often leads to the pavement damaged. This study assesses the differences of the temperature changes at manhole location from the general asphalt concrete when paved with asphalt concrete using the infrared thermal imager. The study found that the use of infrared thermal imager can get the difference of temperature of asphalt concrete pavement between the manhole position and the non-manhole position, and also can determine the position and width of manhole, so as to help to the construction compaction and quality control. Furthermore, because the temperatures of pavement at manhole position and non-manhole position are different, when the pavement damaged and need to dig the pavement for maintaining, the infrared thermal imager can be used to find nonmetallic manhole for construction management reference.

Abstract: The highway has been growing with the development of China's economy and among which asphalt concrete pavement is widely used in highway construction with its many advantages such as good slip resistance, durability, surface smoothness, strength, stability and easy maintenance. This paper takes the highway construction of Yunfu to Zhanjiang section of the Shan-Zhan Expressway and branch line of the LM10 contract section as an example to explore the quality of raw materials, construction quality and other aspects of asphalt concrete pavement. It is hoped that it will help to promote the construction quality of asphalt concrete pavement.
