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.
