FHWA TECiNICAL ADVISORY T 5080.14 June 5, 1990 surface.. Expansion material, sized to accotmnodate end movements, is placed on one side of the beam along with a bond-breaker between the pavement and the sleeper slab. In highly corrosive areas the beam should be treated with a corrosion inhibitor. Several States have reported premature failures of WF beams where the top flange separated from the beam web. Stud connectors should be welded to the top flange, as shown in Figure 1, to prevent this type of failure. Table 2 and Figure 1 contain recommended design features. TABLE 2 - Recommended WF Beam Dimensions WF Beam (weight and dimensions) CRCP Embedment WF Beam Flange Web Thickness in "Sleeper" Size Thickness (in.) slab - in. Width (in.) Thickness (in.) i 6 5 14 x 61 10 5/8 318 10 6 16 x 58 8-l/2 518 7/16 11 5 (b) The lug anchor terminal treatment generally consists of three to five heavily reinforced rectangularly shaped transverse concrete lugs placed in the subgrade to a depth below frost penetration prior to the placement of the pavement. They are tied to the pavement with reinforcing steel. Since lug anchors restrict approximately 50 percent of the end movement of the pavement an expansion joint is usually needed at a bridge approach. A slight undulation of the pavement surface is sometimes induced by the torsional forces at the lug. Since this treatment relies on the passive resistance of the soil, it is not effective where cohesionless soils are encountered. Figure 2 shows a typical lug anchor terminal treatment. 3.6.6
