PRODUCT DESCRIPTION 

(e New Hardware or 

• Significant Modification 

(' Modification to 

Existing Hardware 

The test installation for the PennDOT W-Beam Guiderail over Underground Structure consisted of a 31-inch tall 

W-beam guardrail supported by steel posts installed in compacted base, with a Texas Department of 

Transportation (TxDOT) downstream anchor terminal (DAT) [GF (31) DAT-14] on each end, for a total 

installation length of 181 ft-3 inches. Timber blockouts for steel posts (PDB-01 b) were installed on posts 3 

through 28 using 10-inch long guardrail bolts and recessed guardrail nuts (FBB03). 

Standard 12-gauge W-beam guardrail (type RWM04a) was used in the system. The top of the W-beam was 31 

inches above grade, and the guardrail splices were located mid-span between every other post. Posts were 

equally spaced at 6 ft-3 inches. 

Posts 3 through 13 and 20 through 28 were 6-ft W6x 8.5 guardrail line posts (PWE0l ). These posts were 

installed approximately 40 inches deep in drilled holes that were backfilled and compacted with soil meeting 

Grading B of AASHTO standard specification M147-65(2004) "Materials for Aggregate and Soil Aggregate 

Subbase, Base and Surface Courses." 

Posts 14 through 19 were attached to steel reinforced concrete slabs, 60 inches square by 8-inches thick, with 

their tops located 6 inches below grade. Posts 14 through 19 were fabricated from 371/s-inch long sections of 

W6x8.5 welded to 3⁄4-i nch thick base plates. The posts were secured to the slabs with 3/s-inch diameter x 81⁄2­

inch long bolts that were integrally cast in the slabs. The slabs were covered with the aforementioned Grading 

B soil to the grade level of the surrounding soil. 

Each TxDOT GF (31) DAT-14 terminal was 9 ft-41⁄2 inches long as measured from their anchor posts to the Wbeam splice between posts 2 and 3 and posts 28 and 29, respectively.

found in AASHTO M 180. The bolt sha ll have 5/8-11 [M 16x2] threads as defined in ANSI B 1.1 

[ANSI BI. I 3M] for Class 2A [6g] tolerances. Bolt material shall conform to ASTM A307 Grade A 

[ASTM F 568M Class 4.6], with a tensile strength of60 ksi [400 MPa] and yield strength of 36 ksi 

[240 MPa] . Material for corrosion-resistant bolts shall conform to ASTM A325 Type 3 [ASTM F 

568M Class 8.8.3], with tensi le strength of 120 ksi [830 MPa] and yield strength of 92 ksi [660 MPa]. 

This bolt material has corrosion resistance comparable to ASTM A588 steels. Metric zinc-coated 

bolt heads shall be marked as specified in ASTM F 568 Section 9 with the symbol "4.6." 

Nuts shall have ANSI BI. I Class 2B [ ANSI BI. 13M Class 6h] 5/8-1 1 [M 16x2] threads. The 

geometry of the nuts, with the exception of the recess shown in the drawing, shall conform to ANSI 

B 18.2.2 [ANSI B 18.2.4.1 M Style I] for zinc-coated hex nuts (shown in drawing) and ANSI B 18.2.2 

[ANSI B 18.2.4.6M] for heavy hex corrosion-resistant nuts (not shown in drawing). Material for 

zinc-coated nuts shall conform to the requirements of AASHTO M 291 (ASTM A 563) Grade A 

[ AASHTO M 291 M (ASTM A 563M) Class 5], and material for corrosion-resistant nuts shall 

conform to the requirements of AASHTO M 29 1 (ASTM A 563) Grade C3 [AASHTO M 29 1M 

(ASTM A 563M) Class 8S3]. 

When zinc-coated bolts and nuts are required, the coating shall conform to either AASHTO M 232 

(ASTM A 153/ A 153M) for Class C or AASHTO M 298 (ASTM B 695) for Class 50. Zinc-coated 

nuts shall be tapped over-size as specified in AASHTO M 291 (ASTM A 563) [AASHTO M 291M 

(ASTM A 563M)], except that a diametrical allowance of 0.020 inch [0.510 mm] shall be used 

instead of 0.016 inches [0.420 mm].

SPECIFICATIONS 

W-beam and thrie-beam guardrail posts shall be manufactured using AASHTO M 270 / M 270M 

(ASTM A 709 / A 709M) Grade 36 [250] steel unless corrosion-resistant steel is required, in which 

case the post shall be manufactured from AASHTO M 270 / M 270M (ASTM A 709 / A 709M) 

Grade SOW [345W] steel. The dimensions of the cross-section shall conform to a W6x9 

[W150x13.5] section as defined in AASHTO M 160 / M 160M (ASTM A 6 / A 6M). [W150x12.6] 

wide flange posts are an acceptable alternative that is considered equivalent to the [W150x13.5]. 

After the section is cut and all holes are drilled or punched, the component should be zinc-coated 

according to AASHTO M 111 (ASTM A 123) unless corrosion-resistant steel is used. When 

corrosion-resistant steel is used, the portion of the post to be embedded in soil shall be zinc-coated 

according to AASHTO M 111 (ASTM A 123) and the portion above the soil shall not be zinc-coated, 

painted or otherwise treated. 

Dimensional tolerances not shown or implied are intended to be those consistent with the proper 

functioning of the part, including its appearance and accepted manufacturing practices. 

INTENDED USE 

Posts PWE0 1 and PWE02 are used with the SGR04a and SGR04c guardrails and the SGM04a 

median barrier. Blockouts like PWB0l (steel) or PDB0l (wood) are attached to each post. 

Post PWE03 is used with the SGR09a guardrail and the SGM09a median barrier. Wood or plastic 

blockouts like the PWB02 are attached to each post with FBB03 bolts and FWC16a washers under 

the nuts. 

Post PWE04 is used with the SGR09b guardrail and the SGM09b median barrier. A modified steel 

blockout PWB03 is attached to each post with at least two 1.5-inch [40 mm] long FBX16a bolts and 

nuts.
