<br />C~ <br />i <br />1) Aright of way of 60 feet (the same as the existing road), <br />2) 1.25" thickness of chipseal <br />3) 4" thickness of class 6 roadbase <br />4) 14" thickness of class 2 pit run gravel where the largest size stone will be 8" in size. <br />5) chipseal width of 24.0 feet (same as existing road) <br />6) Total road width = 26.0 feet <br />7) 2% grade from centerline to each side <br />8) 4% superelevation on curves <br />9) Compaction of all surtaces to 95% AASHTO T 180. Test results throughout the road <br />length will be submitted to the County demonstrating this compaction. <br />10) Inside road ditch in all cuts which will be at least 1.5 feet deep and 2:1 sideslopes <br />11) Maximum fill slope - 2.OH:1.OV <br />12) Maximum cut slope - 1.5H:1.OV <br />13) Minimum horizontal curve - 200 feet radius. An existing curve immediately north of the <br />detour is less than 100 feet in radius. <br />14) All vertical curves have a sight distance of at least 140 feet except for the curve at 18+52 <br />which is sharper due to the need to accommodate the crossing of the West Lateral Ditch <br />(pipeline). This grade cannot be changed for pipeline hydraulics. <br />15) Prior to chip seal, the road surface will be treated with MC-70 or comparable product <br />16) As seen on the profile on Map 5, the maximum grade of the route is 11.0% in a length of <br />220 feet from station 28+80 to 31+00. This is the section where the road descends toward Tuttle <br />Draw. The County Engineer preferred the steeper grade in this section over a shorter sight <br />distance. <br />(Revised 72100) <br />Attachment 2.05.3(3) -10-105 <br />
