    Puppala, Anand J.
    1994-06-01 | PDF
    The 1986 AASHTO Guide for the Design of Pavement Structures has adopted the use of resilient modulus (M,) as a fundamental proponent to characterize flexible pavement materials. The resilient modulus is defmed as the ratio of the repeated axial deviatoric stress to the recoverable axial strain. The Louisiana Department of Transportation and Develop ...
  • A parametric evaluation of fundamental engineering properties for Louisiana hot mix final report
    A parametric evaluation of fundamental engineering properties for Louisiana hot mix : final report.
    Mohammad, Louay N. ;
    Paul, Harold R.
    1994-06-01 | PDF
    Historically, asphalt concrete has been designed and constructed using empirically developed criteria which has been based on static loading conditions. As loadings increase and stress distributions change due to increased tire pressures such criteria become insufficient to provide durable pavements. Recognizing this design deficiency, in 1986 AASH ...
