• A positive interlock system to stop all vibration and tamping elements when forward motion of the machine stops .
• A mechanical device that accurately spaces and positions the required tie bar reinforcement that allows satisfactory mechanical or manual tie bar insertion, and a non- oscillating extrusion plate with an adjustable angle of entry.
Provide an electronic monitoring device meeting the following characteristics and requirements to display the operating frequency of each individual internal vibrator for concrete pavement placed by the slip- form method:
• Contains a readout display near the operator’s controls, visible to the operator and the Representative.
• Operates continuously as the paving machine operates .
• Displays all the vibrator frequencies with manual and automatic sequencing for each of the individual vibrators.
• Records the following at least every 25 feet of paving or at least every 5 minutes:
ͦ Clock time ͦ Station location ͦ Paver track speed ͦ Operating frequency of individual vibrators
Do not operate equipment, other than sawing equipment or a lightweight profiler , on the new pavement slab as specified in Section 530.3(q) . Do not operate equipment wheels or tracks within 4 inches of the slab edge.
When tie bars are mechanically inserted, verify location of tie bars every 500 feet in tangent sections and 100 feet through horizontal curves to confirm that tie bars are inserted no closer than 24 inches from the transverse joint.
F inish the surface of all travel and passing lane pavements with a longitudinal texture as specified in Section 501.3(k)4.a . Finish all other pavement surfaces as specified in Section 501.3(k) 4.a or Section 501.3(k)4. b.
include but are not limited to any full width lane used for travel, passing, climbing, center turn, acceleration, deceleration, and ramps.
include but are not limited to approach slabs, bridge decks, tapers, shoulders, medians, or other pavement surfaces as directed.
530.3(q) 530.3(s) The Representative will determine when pavement may be opened to traffic. D o not open pavement to traffic or operate heavy equipment on it until the concrete has reached a
