• Abstract:
  The stiffness (elastic modulus and shear modulus) and Poisson’s ratio of the base and ; sublayers are important parameters in the design and quality assurance during construction of ; highway pavements. During and after the construction of a pavement, it is very important and ; cost-effective to have a mobile and automated system that can measure the stiffness and ; Poisson’s ratio of in-situ compacted soils accurately and quickly. The new highway construction ; guide proposed by AASHTO (American Association for State Highway and Transportation ; Officials) recommends such measurements be conducted. The final report for NCHRP 1-37A ; considers such measurements as crucial. The currently used techniques such as CBR (California ; Bearing Ratio), resilient modulus, DCP (Dynamic Cone Penerometer) and FWD (Falling Weight ; Deflectometer) tests have limitations that can not satisfy all the requirements for design and ; quality assurance of highway pavements.
