Mechanistic Interpretation of Nondestructive Pavement Testing Deflections
… of material properties in flexible pavements based on the interpretation of surface deflection measurements. ILLI-PAVE, a stress-dependent finite element pavement model, was used to generate data for developing algorithms and nomographs for deflection basin interpretation.

Analyzing Skid Resistance and Tire/Road Noise on Porous Pavement Using Numerical Modeling
… and tire/road noise are major concerns in pavement functional performance. Porous pavement enhances skid resistance through inner drainage and reduces tire/road noise through acoustic absorption. This study attempts to explore the development of numerical models in predicting skid …

Analysis of tire-pavement interaction and pavement responses using a decoupled modeling approach
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 the analysis of the mechanism of tire-pavement interaction and the effect of tire-pavement interaction on …

Development of deformable tire-pavement interaction: contact stresses and rolling resistance prediction under various driving conditions
… have been seen in the analysis of flexible pavements, one of the most important factors is still oversimplified: the tire. This can result in costly decisions, such as poor structural road design, incorrect damage prediction, and inappropriate adoption of maintenance/rehabilitation …

Investigation of Elastic Parameters and Pavement Modeling With Eps Geofoam
<p>Models using EPS geofoam rely on input elastic parameters derived from compression tests on small size samples. Young's modulus and Poisson's ratio are parameters required to model isotropic and homogenous material behavior. For the most widely used EPS density grade of 20 Kg/m3 (1.25 pcf), …

Investigation on the mechanisms of block cracking in asphalt pavements
Block cracking in asphalt pavements is a primary form of surface cracking but has been the subject of very few scientific investigations. The extensive nature of this cracking form often leads to significant maintenance costs and reduces the ride quality and service life of the pavement surface. …

An investigation of the effect of dynamic and static loading to geosynthetic reinforced pavements overlying a soft subgrade
… in terms of bearing capacity can occur when pavements are constructed over such soft soils. When road pavements, which are constructed over soft soils, are subjected to cyclic traffic loading (dynamic in nature), rapid deterioration of the base layer material and progressive permanent …

Model based pavement-vehicle interaction simulation for life cycle assessment of pavements
… true for the roadway Network and the design of pavements in it. Vehicle fuel consumption required to overcome resisting forces due to pavement-vehicle interaction (PVI) is an essential part of life-cycle assessment (LCA) of pavement systems. These PVIs are intimately related to pavement …

Role of pavements in urban energetics
… of the day. To determine the contribution of pavements to the development of microscale UHI, two research aims were pursued: (a) the thermal and optical characterization of asphalt and concrete, and the factors that influence them; and (b) the development and validation of an urban climate …

Implementation of mechanistic-empirical approach for structural design of hydrated lime modified flexible pavement
… and rehabilitation of highway and airport pavements has been recognized for many years. Mechanistic methods are based on the principles of mechanics in contrast to the particular purpose and empirical procedures that are often used.The objective of this study is the development of …
