CONNECTING CABLES

SEE DETAILS AT RIGHT

NOTE:

REINFORCEMENT BARS SHALL BE #5 STEEL DEFORMED, AASHTO M 31, GRADE 60.

CONNECT REBAR WITH WIRE TIES AT ALL INTERSECTIONS AND CHAIR LOCATIONS.

CONCRETE SHALL BE 4000 PSI @ 28 DAYS, AIR ENTRAINED (5% MIN.), 3/4" MAX.

SIZE AGGREGATE AND CONTAIN NON-METALIC FIBER REINFORCEMENT.

CONNECTING CABLES

NOTE:

PRECAST 3/4" CHAMFER IN THE EXPOSED OUTSIDE SURFACE CORNERS & EDGES.

TOP SURFACE OF EACH PLANK SHALL HAVE 1/2" WIDE GROVES, 1/2" DEEP, AT

9", 18" & 27" FROM STARTING EDGE, FORMED LENGTH WAYS ALONG THE PLANK

AND A MEDIUM BROOMED FINISH OR 1/4" DEEP TINED FINISH OVER ENTIRE SURFACE.

CONNECTING CABLE DETAIL

NOTES:

1. CONNECTING CABLES SHALL BE 5/8" DIAMETER CORROSION

RESISTANT WIRE ROPE.

2. CABLE CLAMPS SHALL BE OF THE GALVANIZED MALLEABLE TYPE.

3. ISOLATE CABLES FROM INTERNAL REBAR AND OTHER CABLES WITH

APPROVED MATERIAL TO PREVENT CORROSION.

4. BOTTOM OF PLANKS MAY BE CAST AGAINST ANY HARD SURFACE THAT

WILL LEAVE A UNIFORM SURFACE AND THICKNESS.

5. CURE PLANKS 7 DAYS MINIMUM BEFORE LIFTING WITH SLINGS.

6. DO NOT USE CONNECTING CABLES TO LIFT PLANKS.

7. SCORE 1/2" WIDE BY 1/2"DEEP GROVES AS SHOWN ABOVE LEFT AND

APPLY MEDIUM BROOM FINISH TO PLANK SURFACE FOR TRACTION

OR 1/4" DEEP TINED FINISH OVER THE ENTIRE SURFACE.

8. IF ENDS OF CONNECTING CABLES NEED TO BE TRIMMED TO ALLOW

PROPER FIT, THEY SHALL BE SHEARED AND TREATED WITH ZINC PAINT.

9. CONCRETE SHALL CONTAIN NON-METALIC REINFORCING FIBERS. ADD

FIBERS TO THE CONCRETE MIX IN PROPORTION TO THE MANUFACTURER'S

RECOMMENDATION. FIBER SHALL CONFORM TO ASTM C1116.
