ANALISIS REDESAIN PERKERASAN LENTUR MENGGUNAKAN METODE BINA MARGA 2017 DENGAN EVALUASI STRUKTUR PROGRAM KENPAVE

Jalan Jampang Tengah – Kiara Dua (Km. Bdg 139 + 000 – Km. Bdg 142 + 000) is a secondary arterial road which is a logistics route for products and services, thus allowing many heavily laden vehicles to pass through this road, due to traffic density on this road It's not too busy, but the large number of trucks passing by and the lack of maintenance causes this road to quickly become damaged. This research was conducted to provide a road redesign plan with flexible pavement using the 2017 Bina Marga road pavement design manual method with a structural evaluation program kenvape to obtain an optimal pavement structure and to determine the strain value in the road structure and also to determine the planned life of the structural redesign MDPJ Bina Marga 2017 method pavement which can be used as an alternative design by related parties. Based on the results of research related to flexible pavement redesign using the 2017 Bina Marga road pavement design manual method, the results showed that the thickness of the pavement was 4 cm, the AC-BC layer was 13.5 cm, the thickness of the CTB top foundation layer is 15 cm thick, and the class A lower foundation layer is 15 cm thick. From the results of the evaluation of the 2017 Bina Marga flexible pavement planning structure using the kenpave program, it was obtained that the strain value in the pavement design with a value at a depth of 9.9997 cm below the surface of the pavement would experience a type of fatigue cracking of 0.0001914, for horizontal strain values at a depth of 9.9997 cm below the pavement surface will experience rutting of 0.0003486, and for the vertical strain value at a depth of 52.0003 cm below the foundation layer, there will be permanent deformation damage of 0.0002147. And the design age used for redesigning the thickness of flexible pavement layers using the 2017 Bina Marga road pavement design manual method is 20 years.
