611.2Materials
1 None specified.
611.3Construction
1 Determine the necessity for lane or shoulder closures relative to the construction requirements to accomplish the work. Use flagging operations on two- lane, two-way facilities and lane closures on multilane facilities. Provide and maintain lane closures and shoulder closures as specified in these Specifications, in the MUTCD, and on the Standard Drawings , unless otherwise specified on the Plans, in the Special Provisions, or by the RCE. 611.3.1 Paving and Resurfacing Operations 1 Ensure that grade elevation differences do not exceed the requirements in Subsection 601.3.3 . 2 Before beginning any roadway surface work that will alter the grade elevation of the edge of pavement of the roadway , install “LOW SHOULDER” signs (W8 -9) where the temporary grade elevation difference between the surface of the edge of pavement and the surface of the earth shoulder immediately adjacent to the edge of pavement will exceed 2 in. but remain less than or equal to 3 in. The signs may be mounted on ground mounted or portable sign supports. 3 Install the “ LOW SHOULDER ” signs in each direction throughout the length of the roadway intended for the roadway surface work at intervals not to exceed 1 mile with the initial sign encountered by motorists installed at a location no further than 150 ft beyond the beginning of the project limits of the roadway subject to the roadway surface work. Install “ LOW SHOULDER ” signs in each direction no further than 150 ft beyond intersections with side roads. 4 Maintain all “ LOW SHOULDER ” signs within the termini of the project until the shoulder conditions have been dressed and contoured to an acceptable final cross- slope profile to the satisfaction of the RCE. 5 During paving operations, ensure that the length of roadway that may remain open to traffic with an acceptable grade elevation difference of less than or equal
