The increased utilization of mines raises overburden wastes over time. Overburden wastes can be exploited as construction and pavement materials in order to reduce waste depots. The present study explores the geotechnical properties of two overburden wastes of Golgohar mine, Iran. After stabilization with Portland cement at fractions of 5%, 7%, and 9%, samples were compacted at the standard and modified Proctor energy levels. The specimens were then cured and subjected to unconfined compressive strength (UCS) and durability tests. The result shows that the cement-stabilized samples with a cement fraction of 5% met the minimum required UCS and durability for the stabilized base materials. To model the UCS and mass loss of the two cement-stabilized overburden wastes, the response surface method (RSM) was implemented and validated using the hold-out cross validation method. The results of the performance indicators as well as the validation of the developed models showed high accuracy of these models for predicting UCS and durability.
