A thermodynamically compatible rate type fluid to describe the response of asphalt
نویسندگان
چکیده
In this paper, we develop two models from a thermodynamic standpoint that are capable to describe the response of nonlinear viscoelastic fluids. We test the efficacy of both models by comparing their predictions against torsion experiments conducted for asphalt, a material that is notoriously difficult to model. Both the models seem to describe the response adequately, though neither is really very accurate. This should not be surprising as asphalt is a heterogenous material comprising of many components which is being homogenized and modeled as a single constituent viscoelastic fluid.

Evaluation of Fatigue Properties of Asphalt Mixtures Containing Reclaimed Asphalt using Response Surface Method
This paper presents the effects of different amounts of reclaimed asphalt on fatigue life of asphalt mixtures. Central composite method was used to design of experiments based on response surface method (RSM). Binder type (Pen 60/70 and Pen 85/100), reclaimed asphalt pavement (RAP) content (25, 50 and 75%) and loading strain (150, 250 and 350 micro strain) were selected as independent variables...
متن کاملInternal Structure Features of Asphalt Mixture for Field Samples
Asphalt mixture is heterogeneous in nature; therefore, macroscopic parameters alone cannot describe the mechanical behavior of the mixture. In recent years, the arrangement of the aggregate particles in terms of spatial and directional distributions, and contact points are considered as the internal structure of asphalt. The main purpose of this paper is to investigate the microstructural chara...

متن کاملInvestigation of stress and heat strain in asphalt workers
Heat stress is one of the harmful factors in workplaces. Asphalt workers are exposed to thermal stress due to the open environment and process. The aim of this study was to assess the heat stress and strain in asphalt workers. This study was conducted on 29 employees of asphalt workstation. The heat stress was measured based on Wet-Bulb Globe Temperature (WBGT). Also, physiological parameters s...
