19 INSTALLATION CHECKLIST 1. Install the appropriate anchor assembly (a) into the ground and align with the traffic flow (see figure 1). a) For concrete installation (required in weak soil), a 32" deep and 8" minimum diameter hole is required for concrete footings. M-05 M-05A b) For standard soil installation, attach soil stabilizer (b) to the anchor (a) and fastened with two 3/8" corner bolts (M-11) and two 3/8" nuts (M-11a) through the 7th and 12th hole from the top of anchor (as shown). 2. Install anchor assembly allowing only two holes above grade. H 3. Slide 6" stub (c) of breakaway assembly into anchor assembly having the bolt location align with traffic flow(see figure 1) and fasten with two 3/8" x 3" bolts (M-05) and nuts (M-05a). 4. If breakaway assembly is pre-assembled, proceed to step 14. M-05 M-05A M-08A M-08B 5. Place the ball bearing assembly (M-07) on the 6" stub (c). M-07 F 6. Place the 18" stub (f) on top of the ball bearing (e) with the 3 hole side of (f) facing oncoming traffic. 7. Align the 18" stub (f), the ball bearing (m-07) and the 6" stub (c). C 8. Slide each flat washer (M-08b) on each of the three inverted 1/2" x 3" stainless steel bolts (M-08). M-08B 9. Insert above bolt (M-08) with flat washer (M-08b) up through notched hole of assembly (c), (M-07) and (f). M Place the second flat washer (M-08b) down on to the above bolts (M-08). 11. Complete by fastening the stainless steel ny-lock nut (m-08a) to the stainless steel bolt (M-08) and tighten snugly down against the top flat washer (M-08b). M-05 M-05A 12. Repeat step 9, 10 & 11 on the two remaining notched holes of the triangular points. 13. After fastening all hardware, torque the three 1/2" stainless steel ny-lock nuts (M-08a) in a circular pattern to 40 ft-lbs maximum. A 14. Slide appropriate upright post assembly (h), (refer to the allowable sign area per post/windload charts), on the 18" stub (f) of breakaway assembly and fasten with three 3/8" x 3" bolts (M-05) and nuts (M-05a).

20 INSTALLATION INSTRUCTIONS 1. Check with utility companies to mark anchor and post location 2. Orientate anchor for correct sign placement (see figure 1, sheet 8 of 14). 3. Use drive cap to install anchor half way, check for plumb. 4. Continue to install anchor until two holes are remaining above surface level. 5. Remove drive cap. 6. Install sign on post using mdot approved hardware for Type II signs and aluminum rivets for Type III signs. 7. Insert post with sign into anchor six holes deep. 8. See Sign-100-Series and Sign-120-Series for appropriate bottom height. 9. Use corner bolt to fasten anchor and post. 10. Following these procedures the post and anchor will be installed according to NCHRP 350.

43 INSTALLATION CHECKLIST 1. Install the anchor assembly (M0-4) into the concrete base and align with the traffic flow (see figure. a) For concrete installation (required in weak soil), a 48" deep and 12" minimum diameter hole is required for concrete footings. 2. Install anchor assembly allowing only two holes above grade.(3" max.) 3. Slide 6" stub (M0-2) of breakaway assembly into anchor having the bolt location align with traffic flow (see figure 1) and fasten with two 1/2" x 4" bolts (M-07) washers (M0-7b) and nuts (M-07a). 4. If breakaway assembly is pre-assembled, proceed to step Place the Slipbase bolt keeper plate (M-08) on the 6" stub (M02). M Place the square Slipbase (M01) on top of the bolt keeper (M08) with the 3 hole side facing on coming traffic. 7. Align the Slipbase (M01), the bolt keeper (M-08) and the 6" stub insert (M02). M Slide each flat washer (M-06b) on each of the three inverted 1/2" x 3" steel bolts (M-06). M-05 M-05A 9. Insert above bolt (M-06) with flat washer (M-06c) up through notched hole of assembly (M-01). 10. Place the second flat washer (M-06b) down on to the above bolts (M-06). M-08 M-06 M-06A M-06B 11. Complete by fastening the nut (M-06b) to the steel bolt (M-06) and tighten snugly down against the top flat washer (M-06b). 12. Repeat step 9, 10 & 11 on the two remaining notched holes of the triangular points. M-07A M-02 M-07 M-07b 13. After fastening all hardware, torque the three 1/2" nuts (M-06b) in a circular pattern to 80 ft-lbs maximum. 14. Slide appropriate upright post (M03), (refer to the allowable sign area per post/wind load charts), into the 8" Slipbase (M01) of breakaway assembly and fasten with two 5/16" corner bolts (M-05) and flange nuts (M-05a).

44 INSTALLATION INSTRUCTIONS 1. Check with utility companies to mark anchor and post location 2. Drill 12" hole 48" deep install concrete foundation. 3. Orientate anchor for correct sign placement (see figure 1, sheet 8 of 14). 4. Continue to install anchor until two holes are remaining above surface level. 5. Check anchor for plumb and square. 6. Install sign on post using MDOT approved hardware for Type II signs and aluminum rivets for Type III signs. 7. Insert post with sign into Slipbase six holes deep. 8. See Sign-100-Series and Sign-120-Series for appropriate bottom height. 9. Use corner bolt to fasten anchor and post. 10. Following these procedures the post and anchor will be installed according to NCHRP 350.

45 PERFORATED STEEL SQUARE TUBE SIGN BREAKAWAY SYSTEM SPECIFICATIONS The breakaway system is designed to allow a traffic sign to breakaway near ground level upon impact by a vehicle. the breakaway system conforms to NCHRP 350 standards for breakaway sign supports. BASIC COMPONENTS: Top coupling, middle bolt keeper plate, bottom coupling, and clamping bolts including nuts and flat washers. 1. Top casting consists of a 8" triangular ASTM A-536 Grade ductile iron casting with a minimum yield strength of 45,000 psi. 2. Bottom coupling consists of a 2 1/2" square steel tube (3/16" 6" long) welded to a 5/8" triangular steel plate. 3. The bottom steel tubing is structural ASTM A-53 Grade B with a minimum Yield Strength of 46,000 psi. 4. The bottom 5/8" thick triangular steel plate is structural ASTM A572 Grade 50 with a minimum Yield Strength of 50,000 psi. 5. Both top and bottom couplings are hot-dip galvanized (zinc coated) finished. 6. Top and bottom triangular steel plates have a bolt circle diameter of 6". 7. Middle bolt keeper galvanized sheet, plate thickness: gauge. 8. Clamping bolt type: Grade 5, zinc plated flanged bolt. 9. Clamping bolt size: 1/2" diameter and 3" in length. 10. Steel nuts are 1/2", zinc plated flanged nut. 11. Flat washers are 3/16" thick, 17/32"I.D, 1-1/8" O.D. 12. Clamping bolt torque: 80 lbs-ft maximum. 13. No scheduled re-torque is required. 14. Periodic inspection is recommended. BUREAU OF HIGHWAY DEVELOPMENT STANDARD PLAN 07/19/16 SIGN-207-D 10 OF15 NOTE: THE ORIGINAL SIGNED COPY IS KEPT ON FILE AT THE.
