These were shown on the proposed screening wall detail sent yesterday. Dean, use these details to assist in determining a cost for the proposed screen wall construction. 2. The cement treated base in the approach slab areas is rejected. See sheet ST -33, SEQ 47 -80 for cement treated base underneath the approach slab requirements. See attached for further detail.

The contractor must use a /4 "(Min) compressible material on both sides of the panel to isolate the coping from the precast panel. When cast -in -place coping is anchored to reinforced concrete pavement, a smooth level -up strip must be provided on the top of the precast panels. The purpose of the level -up is to allow the pavement and coping to move longitudinally relative to the wall without causing damage. Railing and coping joints must be provided at 33' maximum spacing. Railing and coping joints must be placed to coincide with precast panel joints. PRECAST COPINGS: A smooth level -up strip must be provided on top of the precast panels prior to installation of the coping. Shims may be used on top of the level -up strip to facilitate alignment. Total shim thickness not to exceed 1 ". Precast coping must be provided in 10' minimum lengths. JOINTED CONCRETE PAVEMENT: When coping is adjacent to and anchored into jointed concrete pavement, the coping joints must coincide with the pavement joints. JOINT SEALER: The joints between coping segments must be sealed in accordance with the DMS -6310 "Joint Seolant's and Fillers ", joint sealing material, Class 4. The joint must be sealed 3" below and 6" above the adjoining pavement surface, or as directed by the Engineer. The purpose of the joint sealing is to contain surface drainage and prevent infiltration into the retaining wall bockfill. GENERAL NOTES: Details on this sheet are to be used in development of specific details for mounting traffic railing on mechanically stabilized earth (MSE) walls. The specific details proposed must have strengths equivalent to those shown on this sheet. Areas of particular importance are the connection of the coping to the railing, the strength of the vertical coping leg connecting the railing to the anchor slab, and the connection of the coping to the anchor slab or concrete pavement. Shop drawings for the traffic railing foundations must be submitted to the Engineer in accordance with the Item "Retaining Wall ". The shop drawings must include bar bending details. Precasting of the coping or coping and railing will be allowed. The anchor slab, when required, must be cast -in- place. The Contractor's attention is directed to the fact that various configurations of precast coping /railing combinations are covered by patent. The contractor must provide for use of these systems in accordance with Article 7.3. Concrete must be Class "C ". All reinforcing steel must be Grade 60. Longitudinal bars must be ( #4), unless otherwise shown. Coping and anchor slabs must be considered subsidiary to the Item "Retaining Wall ".

Such bars will be furnished at the Contractors expense. 11 Top longitudinal slab bar may be adjusted laterally 3" plus or minus to tie reinforcing. 12 Bend or cut as required to clear drain slots. 13 No longitudinal wires may be in top center of cage. 14 Space U( #4) bars at 4" Max when end region of panel length is less than 6'-0" to side slot drain. Space U( #4) bars at 6" Max when end region of panel length is 6' - 0" and greater to side slot drain. CONSTRUCTION NOTES: This railing may be constructed with slip -forms when approved by the Engineer, with equipment approved by the Engineer. Sensor control for both line and grade must be provided. Tack welding to provide bracing for slip -form operations is acceptable. Welding can be performed at a minimum spacing of 3 ft between the cage and the anchorage. It is permissible to weld to U, WU and S bars at any location on the cage. If increased bracing is needed, additional anchorage devices must be added and welding must be performed in the upper two thirds of the cage. Face of rail and parapet must be vertical transversely unless otherwise shown in the plans or approved by the Engineer. Chamfer all exposed corners. MATERIAL NOTES: All steel components except reinforcing must be galvanized unless otherwise shown on plans. Use Class "C" concrete. Use Class "C" (HPC) if required elsewhere. All reinforcing must be Grade 60. Epoxy coat all rail reinforcement if slab bars are epoxy coated. Deformed welded wire reinforcement (WWR) may be used as an option to conventional reinforcement and must be made in accordance with ASTM A497 (Deformed Wire). Combinations of Reinforcing Steel and WWR or configurations of WWR other than shown will be permitted when the conditions in the table are satisfied. GENERAL NOTES: This rail has been evaluated and accepted to be of equal strength to railings with like geometry, which have been crash tested to meet NCHRP Report 350 TL - 4 criteria. This rail can be used for design Speeds of 50 mph and greater when a TL - 3 rated guard fence transition is used. When a TL -2 rated guard fence transition is used, this rail can only be used for design speeds of 45 mph and less. This railing cannot be used on bridges with expansion joints providing more than 5" movement. Rail anchorage details shown on this Standard may require modification for select structure types. See appropriate details elsewhere in plans for these modifications. Shop drawings will not be required for this rail. Average weight of railing with no overlay is 370 plf.
