1. A right of way of 60 feet (the same as the existing road), <br />2. 1.25" thickness of chip seal <br />3. 4" thickness of class 6 road base <br />4. 14" thickness of class 2 pit run gravel where the largest size stone will be 8" in size. <br />5. Chip seal 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% super elevation on curves <br />9. Compaction of all surfaces 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 side slopes <br />11. Maximum fill slope - 2.01-1:1.0V <br />12. Maximum cut slope - 1.5H: LOV <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 2.05.3(3)-9, the maximum grade of the route is 11.0% in a <br />length of 220 feet from station 28+80 to 31+00. This is the section where the road <br />descends toward Tuttle Draw. The County Engineer preferred the steeper grade in this <br />section over a shorter sight distance. <br />Page 2.05.3(3)-36 October 2015 (TR -69) <br />
