Soil and Material Inputs for Mechanistic-Empirical Pavement Design

Proceedings of Geo-Denver 2007, New Peaks in Geotechnics, held in Denver, Colorado, February 18-21, 2007. Sponsored by the Geo-Institute of ASCE. This Geotechnical Special Publication contains 10 papers on the state of the practice in the implementation of the Mechanistic Empirical Pavement Design Guide. Topics include: laboratory and field characterization needs in relation to modulus input requirements for pavement foundation geomaterial; contribution of geosynthetic reinforcement to granular layer stiffness; resilient modulus property input requirements for geofoam used in pavements; input property needs for the design and construction of roller compacted concrete pavements; a new neural network modeling approach for the mechanistic-empirical design of rubblized concrete pavements; field evaluations and collecting input properties for forensic and rehabilitated design purposes; investigations of subgrade soil settlements of an existing highway alerted by pavement distresses; dynamic cone penetrometer testing of emulsified asphaltstabilized gravel roads; airport runway evaluation using the rolling dynamic deflectometer; base course use of an asphalt recycled pavement material blended with fly ash; and performance evaluations of rigid pavement sections built on stabilized sulfate soils.
