A three-dimensional (3-D) finite element (FE) model was developed to investigate the
dynamic responses of thin, flexible pavement under impulsive loading similar to a falling …

The lightweight deflectometer (LWD) is gaining acceptance and popularity as an in situ spot-
testing device for quality control/quality assurance of earthwork compaction. Little research …

This paper presents findings from an ongoing research study at the University of Illinois that
aims to develop and calibrate improved models for unbound aggregate rutting through …

The proper understanding of tire-pavement interaction is important for the accurate analysis
of load-induced stresses and strains in the pavement structure. This dissertation focuses on …

Scrap tyres are a solid waste material produced in large quantities. One potential way of
disposal is to use rubber particles from shredded tyres as a construction material. Within this …

The main objective of this paper is to present the state-of-the-art in the anisotropic
characterization of unbound aggregate layers to support the development of the next …

This study investigates the combined effects of asphalt concrete (AC) cross-anisotropy and
temperature on asphalt pavement's stress–strain under moving wheel loads. To facilitate this …

Standard repeated load triaxial tests commonly performed in the laboratory do not always
apply the most damaging field loading conditions for predicting resilient and permanent …

Resilient modulus is an important response index for unbound graded aggregate materials
(UGAM) as a drainage layer in pavement structure. In this paper, a large-scale dynamic …

Unbound granular base (UGB) has a cross-anisotropic and nonlinear (stress-dependent)
modulus with a plastic behavior. Existing UGB models address nonlinear cross-anisotropy …
