Appendix C. COMPUTERIZED PAVEMENT DESIGN PROGRAM MUNICIPAL RIGID PAVEMENT DESIGN (MRPS-1) INPUT GUIDE

Latest version.

This appendix provides the necessary information for preparing an input data set for a Municipal Rigid Pavement Design (MRPS-1) pavement design solution. It illustrates the overall input data structure for a single solution. There are 11 cards or card images, each beginning with a four (4) letter descriptor which identifies the type of information contained on each card. Inspection of the figure shows that each variable in the input structure has an assigned name or acronym that corresponds to the variable descriptions presented later.

It is important to recognize that any variable appearing between columns 5 and 10 (with the exception of the first card image) is an "integer" variable and must therefore be entered right-justified in its field and must not have a decimal point. With the exception of the first card images, all variables between columns 11 and 70 are "real" variables and should (for checking purposes) be right-justified and input with a decimal point. Three (3) variables "NPROB" and "TITLE" on card image 1 and "NAME" on card image 4 are known as alphanumeric variables and may consist of any combination of letters, numbers or other display characters between columns 11 and 80.

Other important notes relative to the subsequent input variable descriptions are as follows:

Abbreviations for symbols used:

col.	- column numbers
LF	- linear foot
SY	- square yard
CY	- cubic yard
psi	- pounds per square inch
pci	- pounds per cubic inch
mph	- miles per hour
$	- U. S. dollars

A [default] is the value of the variable that will be assigned by the program if left undefined (blank or equal to zero (0)) by the user.

To demonstrate the Municipal Rigid Pavement Design - 1 program, example input data and the corresponding Municipal Rigid Pavement Design - 1 output are included at the end of this appendix.
