For Data train Menus and Associated Data- Entry Forms
Data train, Modify Current Data train, and Modify Being Data train menus are shown when choosing options 2, 3 or 4, similarly, from the main menu. All three menus are the same in composition. The only distinction between these menus is that in those used for modifying data lines, being data is modified as a relief for stating new data. It's suggested that the options in the data train menu be used in sequence. When modifying an being train it's mandatory to first use option 1 and identify new names for the needed filenames, or to specify that the input and affair lines used before should be overwritten. The coming options may be use in any system for the check

2.3.5 Option 1 original, fatigue life and pattern depth data
The road data that should be entered into the fields are detail is below
1. Filename to Save Data to All entries in this and other nature are saved in this train. The data may be used at a subsequently time and changed if needed.
2. Filename to Affair Results to The results from the analysis will be bound for this train.
The affair is in typical ASCII form and may be observed or edited using any textbook editor. It should be kept in mind still that a line range of 132 characters is used for the affair.
3. Title This is a explanation of the current job for recognition purposes.
4. Number of Layers The number of layers in the pavement section. A outside of six layers are allowed. Note that the roadbed soil( subgrade) is counted as one subcaste.
5. Wheel cargo when the cargo is Equal to half the axle cargo in pounds units.
6. Tire Pressure The pressure is in any type of truck tire in psi unit.
7. Fatigue Life & pattern Depth calculation needed( Y/ N)? The stoner should respond with a Y if fatigue life and pattern depth in the section are to be estimated. Empirical expressions are used to relate the fatigue life and pattern depth to results from the mechanistic analysis. These relations are presently valid only for three- subcaste pavements with AC, base and roadbed soil layers, and for four- subcaste pavements with AC, base, sub base and roadbed soil layers( Baladi1989). Fatigue life and pattern depth estimates for other pavement sections may not be meaningful. The pattern depth is estimated for the number of cargo reiterations causing fatigue failure of the pavement.
