Initial Cost Comparison of Rigid and Flexible Pavements: Under Different Trafic and Soil Conditions

Paper by AKAKIN ENGIN UCAR from ISCR 11th 2010 Seville Spain

In this paper, the economic analysis has been done on both flexible and rigid pavements. These cost analyses play a great role on the decision-making stages in selection of pavement types. In this analysis initial cost of rigid and flexible pavements have been determined for both flexible pavements and rigid pavements according to AASHTO 93 (American Association of State Highway and Transportation (1993) “Guide for Design of Pavement Structures”) design guideline. The pavements were designed under different traffic conditions and different soil conditions. According to the output of design parameters the layer thicknesses and costs are calculated.
