b. Profilograph Testing: The finished surfaces of the pavements shall
have no abrupt change of 3 mm 1/8 inch or more, and all pavement shall
have a Profile Index not greater than specified in Table 10 when tested
with an approved California-type profilograph. If the extent of the
pavement in either direction is less than 60 m 200 feet, that direction
shall be tested by the straightedge method and shall meet requirements
specified above.
