STANDARDS FOR PRIVATE WADS , . - . • Travelway . The traveiway must be surfaced and compacted with a material acceptable to Orange County to the required width of the particular class of road. A crown should be built into the traveiway so that water will drain from the road surface into the side ditch. 'The crown should not be so great as to cause vehicles to slide off the travel-way when ice or show are on the road. • 1 ;"'- ;: i I•,,-,: Generally the road should be crowned as shown in the specifications sheet so that runoff will drain to the ditches on both sides of the road. However,..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 two situations: where it is necessary to cut down on the length of a ditch in order tf. 1 , to reduce the erosion potential by decreasing the volume of runoff r or where it it difficult to construct ditches due to rock or in, curves. i . , . ....**.....'s.ss `'..........,............ , .:....., PITCH OF TRA VELWAY i 1,,......: ; 1 .1::... Surface Materials Acceptable material for surfacing the traveiway is Aggregate Base Course (commonly called "crusher run"). Soil type base materials (commonly called "Chapel Bill Gravel" or"Chapel Bill Grit") will be accepted under the following , conditions i L-- .;;I. The material originates from a quarry approved by the North CArolina . , . , . 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 1*-- '. Planning Department before use. . . . — Fill 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 , .. 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 . , 1 1 . i f 't• _ . . , . I ....„ . , " . ;t• , - - 7 1,4 .,•'.
