One accommodation that has been tried is making use of zinc foil at the w-beam overlap where the zinc's galvanic action slows down the rust. Use thicker sections (aside from the incurable) might additionally lengthen the life, yet upkeep needs to still consist of assessment of the areas and joints. Powder covering of galvanized guardrail is an acceptable visual alternative.


Questions on visual treatments of obstacle terminals need to be addressed to the find producer. Yes. Crash testing under NCHRP Report 350 has shown that these messages might be replaced when not in an obstacle terminal. For brief stretches of damaged barrier it is possibly better to make use of the exact same type messages as in the existing setup, but where longer sections must be repaired replacing posts is appropriate.


When placed in location each system should be physically connected to the following system per the state criterion or per the producer's directions.

The Texas Constant-Slope Barrier is 1070 mm (42 in) high and has a constant-slope face that makes an angle of 10. 8 levels with regard to the upright. California established a Solitary Incline account that makes an angle of 9. 1 levels relative to the vertical (Crash Beams).
