Plans for crash-tested bridge railings for longitudinal wood decks on low-volume roads. [Michael A Ritter; Forest Products Laboratory (U.S.);] -- The plans for crashworthy bridge railings for low-volume roads were developed through a cooperative research program involving the USDA Forest Service, Forest Products Laboratory (FPL); the Midwest.

[Michael A Ritter; Forest Products Laboratory (U.S.);]. these railings, 24 are for concrete bridge decks and 1 is for a wood deck. For wood bridges to compete with other bridges in the future, a range of crash-tested bridge railings for different wood bridge types will be required.
Because of this need, national emphasis was placed on developing a hmited number of crash-tested railings for wood Size: 3MB. oping crashworthy railings for timber bridge decks.
For timber to be a viable material in the construction of bridges, addi tional vehicular railing systems must be developed and crash tested for timber bridge decks. Of the many railing systems that have been crash tested successfully, only one involved a bridge railing for a timber bridge Size: 3MB.

Of these crash-tested railings, 46 were used on concrete bridge decks, and only one was used on a wood deck (11). FHWA (9). By Augusttwenty-five additional bridge rails had been successfully crash tested in accordance with the requirements of the AASHTO Guide Specifications and also approved by the FHWA for use on Federal-aid projects (10).
Of these crash-tested railings, forty-six were for concrete bridge decks and only one was for a wood deck ( Three low-height, curb-type timber bridge railings, in. high square and rectangular curbs and a in. high trapezoidal curb, were developed for longirudinal timber bridge decks located on very low-volume roads.
The crash test program included 34 developmental tests and four full-scale vehicle crash tests. Plans for Crash Tested Bridge Railings for Longitudinal Wood Decks.

There have been several proposals for a service-level approach to railing design that would vary requirements for structures based on the functional classification of the roadway, bridge ge ometry, and the type, speed, and volume of Size: 2MB.

The standard bridge rail will be the “Oregon Two-Tube” rail with curb, with PL-2 rating. The concrete barrier or some other crash-tested rail shape may be desirable in some circumstances.
Do not use railings other than the Oregon Two-Tube unless approved by the chief bridge engineer. Bridge rail must comply with NCHRP test level 2 or 3. Wood laminations span perpendicular to the flow of traffic.
TNL decks are more common than LNL decks since they are less susceptible to delamination. Unlike an LNL deck, the TNL deck requires support from girders or stringers. Figure illustrates the difference between LNL and TNL decks.

Beam type systems are the simplest type of timber bridge. Most c onsist of a series of longitudinal beams supported by piers and abutments.
Typically spans can range from 10 to 30 ft [3 to 9 m] depending on the beam type. Most of the bridges of this type on Delaware’s highway system were built prior to the ’s.5/5(1). For 3R projects, low volume roadways are defined as current ADT of less than Design Speed (low volume roadways) Horizontal Alignment (low volume roadways) Vertical Alignment (low volume roadways) Superelevation (low volume roadways) Grades (low volume roadways) Deficient Bridge Rails (low volume roadways).

In the event of any inconsistency or conflict in its contents and the exceptions given in Section below, the appendix will take precedence and govern.
Low-volume roads shall be considered as side roads with an average daily traffic ADT (for a period of high use) total in both directions, not exceeding vehicles per day. The service function of low-volume roads is usually oriented towards local rural roads, recreational roads, and resource development roads.
Design for these bridge elements shall be in accordance with the AS Bridge Design(4), Part 6, Steel and Composite Construction, for box girders with composite concrete decks, or otherwise to BS Steel, Concrete and Composite Bridges(6), Parts 3, 5 and The results show that with a relatively thin asphalt concrete (AC) layer of in.
as typical for Florida conditions, a WT pavement with a 4-in. concrete layer can be used for low volume roads with heavy (kip single axle) loads. The allowable traffic volume increases as the concrete slab thickness increases.
Conclusion: When all requirements have been met, and when a final decision has been made to replace an existing one-lane bridge by another one-lane bridge, and when Design Approval, specifying that decision, has been obtained, the structural design normally shall produce plans for a bridge 14 ft.
