A quick comparison of the construction costs for these two hypotheticalpavement design examples indicates the typical cost of RMP relative to the twostandard pavement types: AC and PCC. Cost savings for the RMP designsversus the PCC designs are significant in each of these cases. This cost analysisclearly illustrates a critical design principal for RMP as an alternative pavementsurfacing, namely:When an AC surfacing cannot effectively meet the pavement performancerequirements where both an RMP and PCC surfacing can, then the RMPalternative will generally provide significant initial cost savings in terms oftotal thickness design costs.In addition to the initial cost savings for using an RMP design instead of aPCC design, an RMP surfacing can be expected to cost much less in terms ofmaintenance expenditures given a proper design. The most significant maintenancecost savings will result from the lack of joints to maintain and reseal withthe typical RMP surfacing. These cost savings will obviously not apply tosituations where RMP is overlaid over jointed PCC pavements and joints are cutin the RMP surfacing to trace the PCC joints.G - 30
