RECYCLED TRASH AS ROAD BASE IS GOLD AS STATE SAVES $1 MILLION

Almost 200,000 cu yd of trash is being mixed with soil to construct embankments for a realigned highway and planned expressway. The trash was buried since 1959 under a 2 to 4 ft thick layer of earth. Specifications call for mixing the trash with soil on a 1:1 basis. Each layer of the mix must be covered with solid soil. Biodegradable material cannot exceed a thickness of 6 in. Settlement requirements, and the scheduling problems they caused are discussed. Compaction presented few problems. To check water runoff from the trash embankments and silting of the San Diego Creek, earth dikes have been built on both sides of the creek.
