HYDROCOMPACTING SOILS ON THE INTERSTATE 70 ROUTE NEAR GRAND VALLEY, COLORADO

Soils susceptible to hydrocompaction have been identified for approximately 30 miles along the proposed route of Interstate highway 70 east and west of Grand Valley. Owing to arid climate, southern exposure, and occasional intense cloudbursts, the primary modes of earth material movement and deposition are mudflowage, slope wash, and alluvial-fan processes. When wetted these naturally relatively dry and stable deposits can decrease in volume by as much as 15 percent. A drilling and sampling program determined the extent of these materials, and field tests were conducted to determine if they would collapse upon wetting. Five aerial sprinkler sites and two test ponds were constructed. The deposits were then wetted over a period of five months. All sites showed settlement; a maximum of 3. 5 ft. was observed in one of the ponds. A 3-mile construction project will be built to test the effectiveness of prewetting techniques in minimizing future serious damage to pavements built over hydrocompacting soils.
