A crown should be built into the travelway so that water will drain from the road surface into the side ditch. 'Zhe crows should not be so great as to cause vehicles to slide off the travelway when ice or snow are on the road. Generally the road should be crowned as shown in the specifioations,sheet so that runoff will drain. to the ditches cn both sides of the road. Howeverr In some situations it may be desirable not to crown the road but to have the . travelway sloped to a single ditch as shown below. This is applicable in l: situations. where it is necessary to cut down an the length of a ditch in order to reduce the erosion potential by decreasing the volume of runoff, or where it it difficult to construct ditches due to rock or in, curves. i • _ I i I PITCH• OF TRA VEL,WAY i Surface Materials I Acceptable material for surfacing the travelway is Aggregate Base Course (commonly called "crusher run"). Soil type base materials (commonly called "Chapel Hill Gravel" or"Chapel Hill Grit") will be accepted under the following conditions. The. material originates from a quarry approved by the North Carolina t Department of Transportation. The grade of the road is less than 8%. Where the grade is greater than 8% a layer of crusher run stone will: be placed over the Chapel Hill Gravel before compaction. Sources of surface material shall be verified with the•Orange County Planning Department before use. Fin Material where filling is necessary to raise the'roadbed, cross watercourses or fill stumpholes, it shall be done with suitable material that is free of roots i or other organic matter. The fill should be firmly compacted to reduce settle- ment that will cause ruts or holes in the finished road. i i 3
