Description: Designing RCC pavements has been made easy with this Windows-based computer program. The program provides a means of evaluating and designing roller-compacted concrete for industrial pavements such as container ports, rail and truck terminals, and industrial yards that are subjected to heavy off-highway vehicles and equipment. It can also be adapted for conventionally loaded vehicles. The program is derived from the Portland Cement Association’s AIRPORT computer program and PCA’s publication Structural Design of Roller-Compacted Concrete for Industrial Pavements (IS233).
For pavement evaluation, the program determines the critical pavement bending stresses due to any configuration of vehicles or equipment such as industrial trucks, log handling equipment, gantry cranes, fork lifts, and straddle carriers. For pavement design, the program determines required slab thickness to carry the intended traffic.
The program is user-friendly with clearly captioned option buttons, command buttons, text boxes, help screens, and other operational tools. It supports both the in-lb and International System of Units (SI). The program includes loading configurations for many different types of vehicles. It also allows the user to input and store individualized load and axial configurations.
Default values for material characteristics may be used or the user may specify engineering properties of RCC and subgrade support. Sensitivity figures are generated that allow the user to evaluate the effect on thickness design by changing flexural strength or subgrade support values. A single page summary report includes the input parameters and design results.
