Road damage refers to the condition where the road surface experiences physical
damage such as waves, patches, disintegration, ruts, cracks, and potholes. The aim
of this research is to determine the effect of vehicle volume on road damage. The
study was conducted on the Sokaraja-Kaliori road segment. A primary survey was
conducted by counting the number of heavy vehicles, light vehicles, and motorcycles
over three days from 6:00 AM to 4:00 PM. The analysis of the relationship between
heavy vehicles (X1), light vehicles (X2), and motorcycles (X3) with the amount of
road damage (Y) was performed using multiple linear regression analysis with the
stepwise method. The initial findings revealed that the peak traffic volume in terms
of SMP/hour on the Sokaraja-Kaliori segment was 2144.5 on Saturday, 1886.3 on
Sunday, and 2204.1 on Monday. The results indicated that heavy vehicles (X1) and
light vehicles (X2) have an impact on the amount of road damage (Y), with the
resulting model equation being Y = -6.093 + 0.096X1 + 0.024X2 and an R-squared
value of 0.984.
