Road is a land transportation infrastructure that has an important role in the creation of a balance and equitable development among regions. With the road, it is expected that accessibility to goods and or services will improve the economy of the community, so it is necessary to design the road structure in accordance with the guidelines to provide a sense of security and comfort when driving. In order to improve and develop road quality, it is necessary to evaluate pavement thickness using Analisa Komponen 1987 Method and Austroads 2004 Method and analyze pavement damage using Kenpave Program to know strain value that happened on road due to traffic load. Based on calculations that have been done, the results of pavement thickness of Analisa Komponen Method, that are the surface layer of 7,5 cm (Laston MS 340), the base layer of 10 cm (Laston Up MS 340) and the subbase layer of 15 cm (Sirtu Class B). While for Austroads Method, that are the surface layer of 7,5 cm (Laston MS 340), the base layer of 13 cm (Laston Atas MS 340) and the subbase layer of 50 cm (Sirtu Class B). From the calculation of pavement thickness that has been done, then analyzed the damage of pavement bending using Kenpave Program, got fatigue cracking load repetition of 143.484 ESAL and rutting load repetition of 208,241 ESAL for Analisa Komponen Method. While the value of fatigue cracking repetition of 390,302 ESAL and rutting repetition load of 8,369,086 ESAL for Austroads Method. The repetition of the planned loads is 204.859 ESAL. Based on the results of the damage analysis that has been done, shows that the Analisa Komponen Method is not able to withstand the traffic load of the plan, while the Austroads 2004 Method is able to withstand the traffic load during the life of the plan.
