Effect of Soil Conditions on Road Damage at Roads Puncak Joyo Agung, Malang City, Indonesia

Abstract

This study aims to determine the distribution of the types of road damage which can be viewed from the road roughness condition index, knowing the effect of soil conditions on the road and knowing the solutions to overcome the problem of road damage due to soil conditions on Roads Puncak Joyo Agung, Malang City. The method used in this research is a qualitative method. The results of the analysis of the distribution of road damage on the Puncak Joyo Agung road section in Malang City, it can be seen that segment one is slightly damaged, sometimes there are holes, the surface is uneven with the visual value condition, namely 4 -5, the second and third segments are heavily damaged, many holes and all pavement area with a visual value condition of 2-3. The CBR analysis results show that the average CBR is 3.43% <5% with a DDT value of 4.00, so it can be concluded that the subgrade conditions are not good. The solution for repeating the damage is by means of which, among others, it is scratched, leveled, and compacted after which it is coated with buras and can be repaired by giving an additional layer over the layer that has shed grain after the layer has been cleaned. Meanwhile, another solution that needs to be taken is by digging sections of the road which are the points of damage which are then replaced with hard rocky soil that is compacted again and road maintenance is carried out based on Permen PU No.13 / 2011. and compacted after which it is coated with buras and can be repaired by giving an additional layer over the layer that has shed grain after the layer has been cleaned.
