Correlation of Expansive Soil and Road Pavement Conditions Using Data Mining from GIS Portal

Expansive soil has a fairly high shrinkage rate and will affect the strength of the road pavement structure. This paper aims to analyze the condition of expansive soil associated with road pavement damage. The method of collecting road damage data is done by data mining from the GIS portal database owned by Bina Marga. Meanwhile, data on soil conditions was taken from the portal belonging to the Geological Agency. The analytical method used is the statistical approach t- Test - Paired Two Sample for Means. The results of the study show that there is a correlation between expansive soil conditions and road damage. Expansive soil has a significant effect on road damage.
