Abstract. After the success of the electric cars, the future will be based on Connected and Autonomous Vehicles (CAVs) that will change the actual driving mode. CAVs will also change the design of road pavements because their transverse position in the lane produces different distresses compared to the actual cars due to CAVs ability to keep their transverse position con-stantly in the lane,...
Abstract. The low volume rural road pavement is designed with unbound granular layers only which may be designed against rutting. The objective of present paper is to estimate the thickness of granular base layer of pavement based on mechanistic-empirical approach. In present analysis, the pavement has been considered as multi-layered system. Odemark’s method has been used to transform the...
Abstract. Hot-Mix Asphalt (HMA) creep compliance is a primary mechani-cal property input for the AASHTOWare Pavement Mechanistic-Empirical Design (PMED) software for design analysis of rehabilitated pavements. This study investigated the impact of the creep of HMA mixes with re-claimed asphalt pavement (RAP) on the performance of the HMA-overlaid pavements in Kansas. Hierarchical Level 1...
Abstract. Dynamic modulus of Hot-Mix Asphalt (HMA) is a primary mechanical property input for flexible pavement design analysis using the AASHTOWare Pavement Mechanistic-Empirical Design (PMED) software. In this research, dynamic modulus inputs were used for design analysis of 21 newly constructed asphalt surface projects with the PMED software to predict asphalt pavement performance and to...
Abstract. The PMED performance models have been nationally calibrated and may not represent local conditions in a region. Therefore, these models should be calibrated considering the local construction practices, performance, and climatic conditions. An essential step in the calibration process is to select pavement sections. This paper presents a systematic approach to obtaining observed...
Abstract. Micromechanical modelling through the Discrete Element Meth-od (DEM) is adopted for the study of bituminous materials given its capa-bility to replicate complex microstructures behaviour. Typically, DEM models of bituminous materials consist of an assembly of randomly dis-tributed spherical rigid particles which interact using elastic and/or simple viscoelastic contact models, and...
