In this study, an instrumented dynamic cone penetrometer incorporated with time domain
reflectometry (IDPT) is developed to provide portable in-situ penetrometer for evaluation of …

The resilient modulus of subgrade should be estimated for pavement designs that undergo
repetitive loading from vehicular movement. In this study, an in-situ modulus detector (IMD) …

The characteristics and depths of the old roadbed layers must be assessed for the
serviceability and rehabilitation of aging road pavements. This study's objective is to detect …

Despite the clearly stated procedures in current standards, and contrary to its name,
nonstandard execution of the standard penetration test (SPT) has been common. The use of …

The objective of this study is to evaluate the effects of hammer weight and drop height on
compression stress, transferred energy, and strength index in loose layer. An instrumented …

This study aims to investigate the dynamic cone penetration index (DCPI) and dynamic
responses during instrumented dynamic cone penetration test at fixed-end condition (eg …

To improve the accuracy of the standard penetration test (SPT) results, smart measurement
system, which considers the energy transfer ratio into the sampler (ETRsubSampler/sub), is …

The standard penetration test (SPT) and cone penetration test (CPT) are the 2 most
commonly used in situ tests in geotechnical investigations. In this study, various existing SPT …

In slope stability analysis, infinite slope stability has been widely assessed using field data;
however, recently, remote sensing techniques have been developed to determine the …

Engineering parameters reflecting dynamic responses have been used for reliable
subsurface characterization in the field. The objective of this study is to summarize the …
