Asphalt concrete rutting predicted using the PEDRO model

International Journal of Pavement Engineering, 2014
This paper presents a theoretical viscoelastic approach, called PEDRO (PErmanent Deformation of asphalt concrete layers for ROads), for predicting rut formation in asphalt concrete materials subjected to traffic loading. Input data are traffic parameters, asphalt concrete viscosity and asphalt layer thickness. Vertical strains that cause rutting in the

Modeling Asphalt Pavement Rutting under Accelerated Testing

Road Materials and Pavement Design, 2008
ABSTRACT This paper presented a developed mechanistic-empirical (ME) model for simulating the rutting depth of asphalt pavements under the accelerated testing. This model is based on the power law of vertical strain, and it empirically correlates the layer rutting depth to the cyclic deflection.

Empirical Rutting Models of Recycled Mixtures Containing CRM

Pavement Mechanics and Performance, 2006
Recycling of Reclaimed Asphalt Pavement (RAP) is now a normal practice because it saves aggregate resources and reduces environmental pollutants. The performance properties of asphalt mixture containing RAP could be improved by adding additives such as crumb rubber modifier (CRM).

Statistical Model of Pavement Rutting in Asphalt Concrete Mixes

Transportation Research Record: Journal of the Transportation Research Board, 2001
Pavement deterioration models are important inputs for the efficient management of pavement systems, the allocation of cost responsibilities to various vehicle classes for their use of the highway system, and the design of pavement structures. The development of an empirical rutting progression model with an experimental data set from WesTrack is ...

Calibration of Mechanistic-Empirical Rutting Model for In-Service Pavements

Transportation Research Record: Journal of the Transportation Research Board, 1998
Rutting is a major failure mode for flexible pavements. Pavement engineers have been trying to control and arrest the development of rutting for years. Many models are available to relate pavement rutting to design features, traffic loading, and climatic conditions. These models range from purely empirical to mechanistic models.

Development of a Pavement Rutting Model from Experimental Data

Journal of Transportation Engineering, 2000
Properly specified pavement deterioration models are an important input for the efficient management of pavements, the allocation of cost responsibilities to various vehicle classes for their use of the highway system, and the design of pavement structures.

Development and Application of a Rut Prediction Model for Flexible Pavement

Transportation Research Record: Journal of the Transportation Research Board, 2005
A four-layer neural network (NN) was constructed and applied to determine mapping associating factors in the design and testing of asphalt samples with their performance in repetitive rutting tests. A total of 1,586 samples (two samples per data point) were tested to determine rutting with the use of an asphalt pavement analyzer ...

Anisotropic Nonlinear Elastoviscoplastic Model for Rutting of Asphalt Mixtures

Journal of Engineering Mechanics, 2014
Rutting, one of the primary distresses in asphalt pavement, is influenced by the nonlinear deformation of its constituents and their microstructural features such as the directional distribution of aggregates and cracks. This study develops a nonlinear elastoviscoplastic model to systematically account for the aggregate directional distribution and ...

Kinetic model for batch cellulase production by Trichoderma reesei RUT C30

Journal of Biotechnology, 1997
A kinetic model for batch cellulase enzyme production by T. reesei from cellulose substrate is constructed from literature concepts and laboratory data. The key concepts included were four: (i) existence of primary and secondary mycelia; (ii) cellulase production by secondary mycelia only; (iii) the adsorption of cellulase (catalyst) on the particulate
