Drainage has been commonly employed in pavement structures to intercept water from
entering pavement or to lower the water table to control the moisture content on distinct road …

The findings of an extensive literature survey on the structural response of unbound
aggregates are discussed in two companion papers. In this paper, a state of the art is …

The permanent strain behavior of unbound aggregates under repeated loading has been
studied by many researchers over the years. A summarized review of the research into this …

The main feature of Mechanistic-Empirical Pavement Design Guide (MEPDG) versus
AASHTO 1993 is the various variables as inputs including the material properties, traffic load …

The objective of this study is to propose a machine learning-based framework for predicting
the permanent strain accumulation of unbound aggregates. To develop the machine …

While many studies focused on both new and fouled ballast behavior due to contamination
by external fouling agents, far fewer studies have focused on the mechanical breakdown of …

This synthesis series reports on current knowledge and practice, in a compact format,
without the detailed directions usually found in handbooks or design manuals. Each report …

The unbound granular layers (UGM's) and the subgrade of a pavement structure provide a
significant support for the structure as a whole. Hence the mechanical properties of these …

This paper presents findings of a research study focused on investigating influences of
coarse aggregate morphologies on the strength and permanent deformation behavior of …

The rutting of granular pavements was studied by examining the permanent deformation
behaviour of granular and subgrade materials used in a Northern Ireland, United Kingdom …
