Analysis of Damage to Banggoi-Bula Road Section Eastern Seram District

Abstract

Conditions  on  the  Banggoi-Bula  Road,  Eastern  Seram  Regency.  Suffering  from sinking damage, longitudinal cracks and crocodile skin. And the road was widened from  the  direction  of  the  village  of  Jakarta  Baru  to  the  city  of  Bula,  because  the contour of the road was very extreme. The aim of this research is to analyze the type and  level  of  damage,  plan  the  culverts  at  STA  44+645,  45+400,  45+350  and determine the thickness of the pavement layer on the Banggoi-Bula Road section. The research can determine the type of damage on the Banggoi – Bula STA 43+350 and  STA  25+213-25+800  roads  loaded  using  the  PCI  method,  determine  the thickness  of  flexible  pavement  on  the  Banggoi-Bula  Road  section  using  the  2017 Pavement Design Manual method, and determine planning culverts on the Banggoi- Bula Road. After observing the condition of the road pavement surface that occurred on  the  Banggoi-Bula  Road  section,  the  types  of  damage  were  subsidence, longitudinal cracks and crocodile skin cracks. on the Jakarta Baru-Bula Road section starting from STA 43+350, 25+213-25+800 after averaging segment 1 at 20% Very bad  level  of  damage  (very  bad),  segment  2  PCI  value  at  53%  Moderate  level  of damage (fair), and the PCI segment 3 value is 47%. The level of damage is moderate (fair), so the level of damage is bad so that appropriate handling is based on the 2017 Bina Marga method, which is included in the regular maintenance program. From the research results, the dimensions of the culvert channels at STA 44+645, 45+400, and 45+350 were found to be 1.5 m/sec, with a discharge of 4.0187. and from the results of the flexible pavement research analysis, the traffic value on the planned lane is 769,688.64 or 0.76 million ESA5, the thickness of the AC-WC surface layer is 40 mm, the thickness of the AC-BC layer is 60 mm and the thickness of the class A foundation layer is 400 mm.
