Material samples obtained during the subsurface investigation were <br />tested in the laboratory to provide data on the classification and engineering chazacteris[ics of the road <br />base gravels and [he subgrade soils. The results of the field and laboratory investigations aze presented <br />herein. <br />This report has been prepared [o summarize the data obtained and [o present our conclusions and <br />recommendations, based on [he existing conditions encountered and the proposed traffic loadings. A <br />discussion of geotechnical engineering considerations related to improvement of the existing roadways <br />in [he selected areas are also included. <br />PROPOSED CONSTRUCTION <br />We understand that this project will consist of the improvement of the gravel sections for the existing <br />roadways and the consvuction of a new gavel section far the proposed access roads. The existing <br />roadways which will be improved include selected portions of Hatd Road B, Pond A Access Road, <br />Waste Coal Pile Access Road, Magazine Access Road, PM Bay Access Road SW Bleeder Shah <br />Access Road and the Fish Creek Borehole Access Road. The roadways which have yet to be <br />constructed consist of the West Escape Shaft Access Road, Batch Loadout Access Road and the <br />Eastern Dewatering Borehole Access Road. All of the subject roadways will be gravel surfaced. It is <br />our understanding that the haul roads will be subjected to a mixture of automobile and off road haul <br />trucks and loaders. The access roads will generally be limited to pickup traffic and occasional delivery <br />trucks or construction vehicles. <br />(970)879.7888 • Fax(970)879.7891 <br />29585 U.S. 40 West, Box 775226 • Steamboat Springs, CO 80477 <br />
