API RP 1102 Pipeline Highway Crossing
Calculate API RP 1102 pipeline highway crossings. API 1102 is suitable for cased and uncased steel pipeline road and highway crossings. Standard loads for single and tandem axle vehicles are included. The standard soil weight is 18.9 kN/m^3. Soil weight and wheel loads can also be user defined. The design factors are calculated from the figures. For input values outside the range in the figures the values are extrapolated (select either constant value or constant slope option). Extrapolated values should be used carefully. Note : The calculations are based on the SI data values. User input values can be either US units or SI units. Change units on the setup page (click the Setup link on the calc bar). Units can be mixed, and do not need to be consistent.
