Permanent Deformation in Asphalt Concrete

Journal of Materials in Civil Engineering, 1993
Permanent deformation in asphalt concrete pavements manifests itself as depressions along the wheel paths, ruts. The prediction of rut depth requires a knowledge of materials characteristics that relate the asphalt concrete permanent strains to stress and temperature.

Permanent Deformation of Subgrade Soils

Analysis of Asphalt Pavement Materials and Systems, 2007
Few research projects have been conducted on the permanent deformation of subgrade soils in China. Based on a comprehensive literature review, a testing procedure to evaluate permanent deformation in subgrade soils is developed and presented in this paper.

Permanent Deformation In Idealised “Sand Asphalt” Bituminous Mixtures

Road Materials and Pavement Design, 2001
ABSTRACT This paper investigates the quasi-static permanent deformation (rutting) behaviour of two idealised bituminous mixtures (sand asphalts). The permanent deformation behaviour is assessed using simplified quasi-static uni-axial and tri-axial laboratory tests performed over a range of temperatures, stress levels and strain rates.

Characterization of Permanent Deformation of Different Asphalt Pavements Using the Advanced Repeated Load Permanent Deformation Test

CICTP 2016, 2016
An advanced repeated load permanent deformation (ARLPD) test that can simulate the lateral confinement and temperature gradient in actual pavements was employed in this study. The test was conducted based on field cores and laboratory-made specimens of several newly constructed hot mix asphalt (HMA) pavements, reclaimed asphalt pavements (RAP), and ...

Permanent Deformation in Flexible Pavements

Journal of Transportation Engineering, 2004
This paper presents a mechanistic-empirical framework for evaluating permanent deformation in flexible pavements. The procedure uses rational material properties and can be used as an analysis tool, as a companion to the design method. The material properties required are (1) the stress dependent modulus of the pavement layers, asphalt concrete and ...

Permanent Deformation in Asphaltic Materials

Transportation Engineering Journal of ASCE, 1974
This review investigates traffic load-associated causes of permanent deformation in asphaltic materials. The environmental effects of temperature and moisture are also considered insofar as they affect the deformation process. Deformation in nonasphaltic layers which may contribute to deformation of the asphaltic layers they support is also given ...

A review on permanent deformation of granular material

Indian Journal of Public Health Research & Development, 2018
Long-term behavior of a granular material under repeated loading plays a vital role to understand the behavior of rutting in pavements. Many researchers observed the behavior of permanent strain accumulation in the granular material under cyclic loading condition. The permanent deformation of granular material caused by numerous factors varies with the

Analysis of the permanent deformation of automobile hoods

International Journal of Automotive Technology, 2016
One factor that determines the quality of an automobile’s appearance is its appearance integrity, which means that the degree to which an automobile’s physical appearance coincides with its mechanical quality. The painting process of an automobile can cause the permanent deformation of its hood, which lowers its appearace integrity.

Permanent Deformation of Bearing Raceway Surfaces

A S L E Transactions, 1976
Depths of permanent deformation, resulting from the heavily stressed contact of a cylindrical roller on a bearing raceway surface, are evaluated by employing an analytical treatment of elasto-plastic bodies in line contact. Constitutive relations, resulting from that analysis obtained by employing the incremental theory of plasticity in conjunction ...

A New Approach for Prediction of Permanent Deformation

1992
A laboratory investigation was performed in which the influence on resistance to plastic deformation as demonstrated when rounded, smooth, sand-sized aggregate particles were replaced by rough, angular, porous particles while other aggregates and the total gradation remain the unchanged.
