required to connect the curb miters and to splice the steel rails are shown on the shop drawings. Ensure the welds are completed by the fabricator in the shop except at the field splices approved on the shop drawings. 3 Use galvanized ASTM A 709 (Grade 36, 50 or 50W) steel for the snow plow plates and
supporting angles. 4 Use galvanized ASTM A 709 (Grade 36, 50 or 50W) steel for the sidewalk cover plates
when required. Use galvanized flat socket head cap screws conforming to ASTM F835 to attach the cover plate.

2 For circular pipe, the department considers pipe wall design and the use of elliptical
reinforcement optional. 3 For precast flared ends, provide and use sections in accordance with requirements for the
pipe size and type provided, with equivalent wall thickness, concrete, and reinforcement as specified therein for class II, A-II, or HE-II. 4 The engineer will approve reinforced concrete pipe in accordance with section 5.1.2,
under the above-mentioned AASHTO specifications, modified as follows:
The engineer will determine acceptability of pipe in all diameters and classes by compression tests on concrete cores or cured concrete cylinders; by absorption tests on selected samples from the wall of the pipe; by materials certifications for materials required by sections 5, “Basis of Approval,” and 6, “Materials”; by results of materials tests required in accordance with section 7, “Design”; and by inspection of the finished pipe, including the quantity and placement of reinforcement, to determine its conformance with the design specified.
Ensure that plants producing RCP and HERCP are certified in accordance with Subsection 603.4.1, General. 808.1.2 Manhole Risers and Tops
As specified, provide precast, reinforced-concrete manhole risers and tops in accordance with AASHTO M 199 [AASHTO M 199M].
