EVALUATION OF EXPENDITURES ON RURAL INTERSTATE PAVEMENTS IN KANSAS: EXECUTIVE SUMMARY

The purpose of this study was to evaluate the historical expenditures for rural interstate pavements in Kansas and to provide historical performance and cost data to evaluate the assumptions associated with life-cycle cost analysis (LCCA) input parameters currently used in Kansas. The study involved the evaluation of rural interstate pavements on I-35, I-135 and I-70 in Kansas that are administered by the Kansas Department of Transportation. Based on the results of this study, the following conclusions are warranted: (1) For the rural Interstate pavements evaluated, total expenditures in actual dollars and 2001 dollars were less for hot mix asphalt (HMA) pavements than portland cement concrete (PCC) pavements. (2) Original construction costs per 4-lane mile in 2001 dollars were less for HMA pavements than PCC pavements. (3) During the first 20 years of a pavement's life, annual maintenance costs were slightly higher for HMA pavements than PCC pavements. (4) HMA and PCC pavements had the same average service life, 35 years, until rehabilitation or reconstruction. Based on the results and limitations of this study, recommended input parameters for LCCA in Kansas are offered.
