| Abstract | Various design features (such as dowel bars, tied shoulders, or drainable bases) may be added to a portland cement concrete (PCC) pavement design to improve its overall performance by maintaining a higher level of serviceability or by extending its service life. However, the addition of these features also increases the initial cost of the pavement design, in some cases quite significantly. This then raises the question as to whether the improved performance benefits gained by adding the design features are worth the increase in cost. Furthermore, the effects of adding more and more design features to a PCC pavement design may produce smaller and smaller performance gains, while significantly increasing the overall costs of the pavement structure. Unfortunately, current design practices do not always consider this tradeoff between performance benefits and costs when design features are added to a PCC pavement design. This report presents a methodology for quickly assessing the relative costs and benefits of incorporating various design features in PCC pavements. That methodology has been incorporated into an analytical software tool that can be used by pavement design engineers who are interested in investigating the cost versus performance tradeoffs associated with the selection of different design features during the PCC pavement design process. The tool is not intended to provide absolute answers on the effect of different design features, but rather to provide insight into general performance and cost trends associated with the use of those design features. |
