• Grinding shall be accomplished in a manner that eliminates joint or crack faults so there is no more than a 1/16-inch (1.59 mm) differential between the adjacent sides of the joints and cracks. Grinding shall also substantially remove pavement conditions such as warp and curl to provide an acceptable ride. • The grinding shall feather into existing structures such as manholes, water gate valve covers, private utility structures in a manner that eliminates abrupt ridges or drops and provides a uniform texture and acceptable ride. • Lateral drainage shall be achieved by maintaining a constant cross slope between grinding extremities in each lane. The finished cross slope shall mirror the pregrind cross slope and shall have no depressions or misalignment of slope greater than 1/4-inch (6.35 mm) in 10 feet (3.05 meters) when measured with a 10-foot (3.05 meter) straightedge placed perpendicular to the centerline. Steps will be taken to ensure that wheel path rutting is substantially removed and that the grinding operation is simply not texturing the wheel path depressions. Areas of deviation shall be reground. Straightedge requirements will not apply across longitudinal joints, areas where existing structures limit grinding operations or outside the specified ground area. • The maximum removal required in any area shall not exceed 5/8 – inch to 3/4- inch. (15.88 mm to 19.05 mm) Areas where required removal exceeds this limit shall be excluded from smoothness requirements found elsewhere in this specification...
