Abstract:
The primary objective of this study was to evaluate KDOT’s pavement surfacing history and recommend

whether or not the department’s life-cycle cost analysis (LCCA) procedure should include a surfacing history

component, and, if so, how the LCCA process should be revised/ updated to incorporate surfacing history.

An analysis using KDOT’s databases demonstrated that they could be used to estimate performance of

new or reconstructed pavement lives for use in the LCCA process. For the predominant pavement types used

in Kansas, full-depth asphalt concrete (FDAC) and doweled, jointed plain concrete (JPC-D), service lives were

estimated to be 12 years and 20 years, respectively. These compare with 10 years and 20 years currently being

used.

The impact of modifying the service lives for FDAC and JPC-D pavements was evaluated using the LCCA’s

of 12 recent KDOT construction/reconstruction projects. The LCCA’s were obtained and re-computed using lifecycle

models formulated from results of the performance analyses conducted for FDAC and JPC-D pavements

and for maintenance and rehabilitation (M&R) treatments applied to them. The resulting life-cycle costs were

then compared with those computed by KDOT. It was found that modified performance lives resulted in only a

negligible change in the overall NPV for both pavement types on the 12 projects evaluated.

Three alternative methods for computing future rehabilitation costs for use in LCCA were presented and

evaluated. One method, which utilizes a cost-to-own approach, warrants further evaluation and development. The

advantage of the cost-to-own approach is that it does not require modeling of the service lives of the pavement

being studied. It appears the cost data to perform this type of analysis are available in the KDOT data base.
