Geomaterials exhibit elastoplastic behaviour during dynamic and repeated loading
conditions. These loads are induced by the passage of a train or vehicle which then …

This paper develops pavement performance evaluation models using data from primary and
interstate highway systems in the state of South Carolina, USA. Twenty pavement sections …

This paper presents the results from a test program to characterise resilient modulus (MR) of
subgrade soils for different geographic regions in South Carolina. For this study, Shelby tube …

This paper highlights the subgrade resilient modulus (MR), which is recognized as an
important parameter to characterize the stiffness of the subgrade soil for designing flexible …

The subgrade soil stiffness, which depends on the in-situ moisture content and soil index
characteristics, is a key factor in pavement rutting. Due to variations in the compaction …

This study resulted from the need for better consideration of subgrade and unbound layers
on the performance of flexible pavements in Kansas. Thus, the main objective was to …

The primary objective of this research was to identify existing historical data (ie, climate,
traffic, pavement design information, material properties, and pavement performance) within …

The AASHTOWare Pavement METM Design is the next generation of AASHTO pavement
design software, which builds upon the newly developed NCHRP Mechanistic-Empirical …

Transverse cracking is a major distress in asphalt pavements in north-western Oklahoma.
Assessment of probable causes of such distresses is helpful to the design of new pavements …

Since AASHTO released the Mechanistic-Empirical Pavement Design Guide (MEPDG) for
public review in 2004, many highway research agencies have performed sensitivity …
