732.04 Method of Measurement
1.No measurement required.
732.05 Basis of Payment
1.The work described in Section 732 shall not be measured and paid for directly, but shall be considered su bsidiary to the items “Preparation of Bridge at Station _________,” (see Subsection 704.05) and “Remove Structure at Station _________” (see Subsection 203.04). The transportation to and disposal at the selected TSDF shall be considered "Extra Work", and shall be paid for in accordance with Subsection 109.05. - 654 - SECTION 733 -- BRIDGE DECK AND APPROACH SLAB SMOOTHNESS
733.01 Description
1.This Specification applies wh en a new bridge deck is constructed and when an existing deck is replaced. It also applies to bridge ramps when the ramp is an additional paved su rface bridging an obstruction. This Specification does not app ly to overlays of exis ting bridge decks or to bridges built on gravel roads.
2.This Specification estab lishes a standard for bridge deck and approach slab smoothness. It is intende d that the bridge deck placement operation and the approach slab placem ent operation produce a finished driving surface with a profile index no greater than 0.50 inch/100 feet (12 mm/30 m). The smoothness test will be conducted by Department personnel using a 12-foot (4 m) California type profilograph.
733.02 Equipment
1.The 12-foot (4 m) California ty pe profilograph will record the pavement profile by measuring the vert ical movement of a sensing wheel, attached to the frame at mid-point, with reference to the mean elevation of the support wheels at each end. The pr ofilograph will produce a profilogram with a vertical scale of 1 inch (25 mm) equals 1 inch (25 mm) vertically and 1 inch (25 mm) equals 25 feet (7.6 m) longitudinally.
733.03 Test Procedure
1.The profilograph test will be r un after completion of the bridge deck and the approach slabs. In the case of a bridge contract which does not include the approach slabs, but which will be let to contract at a future date, the profilograph test will be run on the bridge deck only.
2.In the case where the approach slabs are not part of the bridge contract but are part of another concurr ent contract, the profilograph test will be run after the bridge deck and the approach slabs are completed. In this case, if the approach slabs and the bridge are constructed by separate Contractors, both Contractor s will receive a profilogram.
3.If the paving or approach slabs are not part of the bridge contract or part of another concurrent contract, the pr ofile of the first and last 6 feet (2
m.(longitudinally) of the surface being tested may not be able to be obtained with the profilograph. These areas will be measured for bumps with a 10 foot (3 m) straightedge according to Paragr aph 9.b. of Subsection 603.03 of the Standard Specifications. Areas showing high spots in excess of 1/8 inch (3 mm) in the 10 foot (3 m) span sha ll ground to the required profile.
4.One profile will be obtained in each lane and shoulder approximately 3 feet from the outside lane line. T he profiles will be divided into test sections each 100 feet (30 m) in length with any remaining short length also considered a test section. The profilogram will be labeled with the stationing, lane designation, pos ition on the pavement, and the direction of travel. All station references used on the profilograms will be actual project stationing.
733.04 Evaluation
1.A profile index will be calculat ed for each section. Results will be furnished to the Contractor within 72 hours of the completion of the tests.
