The states standard drawings for this system need to be reviewed for details that will be specific to that SRT /HBA post system has a straight flare; the earlier versions ofthe SRT-350 used a parabolic (curved) flare. At posts one and two,HBA posts are used in place of the soil tubes and wood posts. Thesame equipment and expertise is required for both systems. Anyone withexperience installing the SRT-350 should have no difficulty installing theSRT /HBA post THE CRT POSTSI nstall the wood posts at locations 6 thru 3. These posts (PC-4063B)may be driven. They may also be installed by drilling holesapproximately 44" (1120 mm) deep. Insert the 6'0" (1830 mm) woodpost into these holes and backfill . Note that in either case, the bottomof the upper 3 1/2" (90 mm) hole in the post is approximately atfinished grade.

4 Posts 3 thru 7 are spaced at 6'3"(1905 mm) 1 INSTALLING HBATMBOTTOM POSTST here are two methods for the installing the HBATM bottom posts atlocations 1 and 2. The posts should be oriented so that the larger hole(13/16" (21 mm)) is placed downstream (away from the end of thesystem).METHOD ADrive the HBA Bottom Posts (PC-33878A) with anapproved driving head to the appropriate depths, approximately72"(1830 mm). The optimum depth will have the bottom of the13/16" (21 mm) holes in the ears even with the finished BDrill a 12" (300 mm) pilot hole approximately 72" (1830mm) deep and Install the HBA Bottom Posts to the appropriate optimum depth will have the bottom of the 13/16" (21 mm) holesin the ears even with the finished Bis used, material should be placed in 6" (150 mm) li ftsand compacted with pneumatic equipment to optimum HBATMPOSTSWHEN ENCOUNTERING ROCKIf rock is encountered when installing the HBA posts, use thefollowing proce dures, unless there is a more restrict ive st rock is encountered and 20" (510 mm) or less depth is required tocomplete the i nstall ation of the bottom HBA post , drill a 12"-16" (300mm - 400 mm) diameter hole in the rock.

5 The hole should be drilled2" (50 mm) deeper than required embedment depth. Place in thebottom 2 inches (50 mm) of the hole for drainage granular material See Figure small pi eces of th e dril le d rock. Backfil l an d compact the ho le afterinstalli ng th e HBATM post . If compactable, the material remov ed from thehole may be used for the backfil rock is encountered and more than 20" (510 mm) depth is required toinstall the bottom HBA post , dril l a 12"-16" (300 mm-400 mm) diameterhole 22" inches (560 mm) deep into the rock. Install the HBA post in thehole. Cut of f the embedded portion so the guardrail will be installed atthe proper mounting height. Place in the bottom 2 inches (50 mm) ofthe hole for dr ainage gr anular material or small pieces of the drilled l an d compact th e ho le after installi ng th e HBA post . Ifcompactable, the material remov ed from the hole may be used for theba the finished gr ade is pa ved around terminal posts l and 2, a 3" deeprecess around each post needs to be provided to allow for the top postto rotate when impacted.

6 (See Figures 6 and 7).The recesses shouldnot be fi ll ed wi th compacted asphalt or HBATMTOP POSTSOnce the bottom posts are installed, the upper post can be post pl ates (ears) can be i nstalle d on ei ther si de of the bottom postplates (ears). At post location No. 1, install the upper post (PC-33876A)by aligning the holes of the post plates (ears) of the upper and lowerposts. In the 7/16" (11 mm) holes, install a 3/8" (10 mm) diameter x 2"(50 mm) hex head bolt wi th a 3/8" (10 mm) w asher, 3/8" (10 mm) l ockwasher under the 3/8" (10 mm) hex nut. See Figure bolts should be i nstalle d so the head of the bolt is on the inside ofthe post plates (ears) and the w asher and lock w asher under the nut areon the outside of the post is no torque requirement for these bolts. They should betightened to a snug 27At post LocationNo. 2, installthe upperpost (PC-33877A)by aligningtheholesof the post plates(ears)on the upperand the 7/16"(11 mm)holes,installa 3/8"(10 mm)diameterx 2" (50 mm)hex headbolt with a 3/8"(10 mm)washer, 3/8"(10 mm)lock washerunderthe3/8"(10 mm)hex nut.

8 These slots should be between posts 1 and 2, 2 and 3, 3 and 4,and 4 and 5. The guardrail panels should be installed so that the slotguard at tachment holes are at the end of the slots away from the end ofthe terminal. See Figure 5 The 12'6" ( m) guardrail panel (PC-39G) or 25'0" (7 .62 m) guardrailpanel (PC-69G) slots should be between posts 3 and 4 and posts 4 12'6" ( m) guardrail panel (PC-30G) anchor br acket holes will bebetween post 1 and post '6" (3 .8 1 m) PANEL OPTION:At post l ocation 7, spli ce and post bolt the 12'6" ( m) ra il panel(PC-9G) to the run of guardrail with hardware provided by the standardguardrail terminal rail should be lapped in the direction of trafficunless the agency's policy dictates post location 5, splice the 12'6" ( m) r ail panel to the 12'6"( m) ra il panelTo ward post 1 Stack 2-3 washers on 3/4" boltBetween post plate & strut to allowstrut to pass over 3/8" bolt (PC-39G) wi th ei ght (8) 5/8" x 1 1/4" (16 mm x 32 mm) spli ce bolts andhex post locations 4, 5, and 6, bolt the ra il panel and wood blockout tothe wood post using a 5/8" x 18" (16 mm x 460 mm) post bolt, a hexnut, and a round w asher.
