The access/haulroad was surfaced with gravel to form a durable road surface. The gravel characteristics conform <br />• to [he following specifications: <br />Screen Size Material passin¢ <br />I-'/, inch 100% <br />linch 75-90% <br />3/8 inch 40-75% <br />No. 4 mesh 30-60% <br />No. 10 mesh 20-45% <br />No. 40 mesh IS-30°io <br />*No. 200 mesh 5- I S% <br />*The fraction passing [he No. 200 mesh shall not be greater than two-thirds of the fraction passing the No. 40 <br />mesh. <br />Acid and/or toxic forming substances were not used in the road surfacing. <br />Vegetation was cleared for no more than the width needed for the roadway and drainage control. <br />A cross-section and centerline profile of the access/haulroad is shown on Map 30, Road Profiles and Cross- <br />Sec[ions. Grade and pitch requirements were not exceeded in road design or construction. <br />Embankment materials utilized conformed to applicable standards. No excess or unsuitable material from <br />excavations was encountered. No acid and toxic-forming materials were encountered during embankment <br />construction. Construction activities of the access/haulroad were conducted in accordance with the approved <br />• permit C-82-056. As-built P.E. certification for this access/haulroad may be found in Exhibit 25, As-built <br />Certifications of Access/Haulroad and Haulroad. <br />^. Haulroad <br />A haulroad was constructed [o connect the TCC haulroad with the CYCC haulroad B. The location of the haulroad <br />is shown on Map 24, Surface Facilities. The centerline road profile and typical cross-section are shown on Map <br />30, Road Profiles and Cross sections. <br />Road design specifications are as described below and comply with Rule 4.03.1, Haul Roads. the planned activity <br />will not be conducted within t 00 feet of a public right-of--way of any public road and will not require relocation of <br />a public road. <br />Drainage ditches have been constructed a[ [he toe of all cut slopes formed by [he construction of [he haulroad with <br />relief cross drains spaced according to [he grade. The road is crowned to prevent ponding of water. Surface dips <br />have been used in conjunction with the ditches to control erosion where required by Rule 4. <br />Crossing the hauhoad an 18 inch corrugated metal pipe was installed at 2% slope to control drainage. Culvert size <br />criteria are included in Exhibit 8, Sediment Control Plan. <br />Moisture content and compaction were monitored during construction. The subgrade was proof compacted and <br />any deleterious or unsound material removed. Road fill was hauled by trucks and scrapers. Material was spread <br />and compacted over [he entire width of [he embankment. Road fill was spread and compacted as follows: (i) <br />• Where there is more than 5 feet of fill, the top ~ feet was compacted to 9~% of AASHTO T-180 and the rest <br />compacted to 90% AASHTO T-180; (ii) Where there is a minimum of3 feet of compacted road till where [here is <br />less than 5 feet of till required. The entire fill was compacted to 95% of AASHTO T-180; and, (iii) Where the <br />road is in a cut, the roadway has been over-excavated and a 3 foot minimum thickness road till placed and <br />MR 97-I ~4 2.0~-67 Revised 9/9/97 <br />
