flexible pavement on the Aek Raso-Maduma Road section has a low soil bearing capacity, of course this will cause problems if proper and appropriate planning is not carried out. If not handled properly, this will cause a decrease in the top base layer and surface layer. Needed acomponent analysis to determine how thick the lower surface layer, top surface layer, and surface layer are needed so that the plan flexible pavement is safe according to the age of the plan.
The method used to evaluate the thickness of the flexible pavement is a component analysis method carried out by collecting primary and secondary data. Primary data collection was carried out through direct survey, whose function is to find out the actual condition. Secondary Data in the form of average daily traffic value (LHR) , california bearing ratio (CBR) data.
Based on the results of calculations carried out using component analysis methods, it is found that the thickness of the base layer is a minimum of 15 cm, minimum surface layer thickness of 5 cm, and minimum subbase layer thickness of 10 cm, but what is carried out in the ground is the minimum base layer thickness of 15 cm, minimum surface layer thickness of 5cm, and the thickness of the subsurface layer just add heaps of sirtu with thick thickness variations accord to ground conditions, so that it was found that the road improvement was carried out on the Aek Raso-Maduma section it can be said that it does not meet the minimum foundation design standard specifications, because if the CBR data of soil bearing capacity is below 6%, it should use a subbase layer minimum thickness of 10 cm, which can be seen from the table of minimum design standard specifications.
