![]() Impact factors for rail loads shall be calculated in accordance with the AREMA Manual for Railway Engineering. The use of this term shall be in specific reference to the AREMA Manual for Railway Engineering. The Department will, when possible, perform AASHTO, AREMA and/or ASTM tests of the materials for acceptance purposes. The minimum lateral wind pressure shall be fifteen pounds per square foot (15 psf). Lateral wind forces for the temporary conditions shall be considered in accordance with AREMA, Chapter 8, Section 28.6.2. If there is any excavation near the walkway, a handrail, with 10’-0” minimum clearance from centerline of track, shall be placed and must conform to AREMA and/or FRA standards. Shoring will be provided in accordance with AREMA Manual for Railway Engineering Chapter 8, part 28 except as noted below. Lateral pressures due to surcharge shall be computed using the strip load formula shown in AREMA Manual for Railway Engineering, Chapter 8, Part 20.Īllowable stresses in materials shall be in accordance with AREMA Manual for Railway Engineering, Chapter 7, 8, and 15.
