Abstract: As the scale of highway construction continues to expand, the complex terrain environment has become the main factor affecting highway construction. Based on the principle of economy, in this type of road construction,stone-filled roadbeds with large-size fillers are often used. Studies have shown that selecting strong and hard stones,optimizing the construction rolling combination and compaction parameters, strengthening foundation treatment, and doing a good job in slope protection can improve the construction quality of stone-filled roadbeds. Based on the actual construction conditions of a project, this paper adopts the construction technology of stone-filled roadbed to reduce the project cost. Practice has proved that the application of the stone-filled roadbed construction technology has good results.
