The Analysis of Road Condition on the Performance of Muara Teweh – Puruk Cahu Road Section

The existing condition of Muara Teweh-Puruk Cahu road section with ± 100 km long is mostly uphill and bend that currently is experiencing significant damage. This study aims to determine the type of damage in Muara Teweh-Puruk Cahu road section and to analyze the correlation between damage and vehicle speed on flat roads and hilly terrain. The study was conducted by collecting primary data in the form of data of road damage, vehicle speed, and road geometric. Data analysis of road damage is done by the BinaMarga method to obtain the type of damage. The correlation between road damage and vehicle speed is shown in a regression model. The results of the analysis show the vehicle speed will tend to decrease as the increasing number of road damage. The speed of light vehicles on roads with flat terrain shows a very strong correlation with the type of damage, such as cracks, grooves, and depression. The speed of light vehicle going uphill shows a very strong correlation with the type of damage, such as cracks, grooves, potholes, and depression. Meanwhile, when the vehicle goes downhill, it is seen a strong correlation with the types of damage such as cracks, grooves, and depression. The speed of heavy vehicles on roads with flat terrain shows a very strong correlation with the type of damage like cracks, grooves, potholes, and depression. The speed of heavy vehicle when going uphill shows a very strong correlation with the type of damage like cracks, grooves, potholes, and depression. Meanwhile, when the vehicle goes downhill, it is shown a very strong correlation with the types of damage like cracks, grooves, and depression.
