Evaluation of permanent deformation of a new pavement base and subbase containing unbound granular materials, crumb rubber and crushed glass

Journal of Cleaner Production, 2019
To avoid premature failures in pavement layers, strong aggregates must be selected for pavement constructions that can bear the accumulation of permanent deformations. Otherwise, rutting happens in the pavement layers due to the accumulation of permanent

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

Permanent deformation behaviour of black cotton soil treated with calcium carbide residue

Construction and Building Materials, 2019
Uncontrolled dumping of huge quantities of calcium carbide residue (CCR) which is an industrial by product of acetylene gas industry is hazardous to environment due to its high alkalinity.

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 ...

Long-term permanent deformation behaviour of recycled concrete aggregate with addition of crumb rubber in base and sub-base applications

Soil Dynamics and Earthquake Engineering, 2019
The structural behaviour of pavements depends on the permanent and resilient deformations. These deformations are accumulated during the pavement lifetime. Although many studies have been done to explore the use of construction and demolition (C&D) waste

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 ...

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.

Effect of freeze-thaw cycles on the resilient moduli and permanent deformation of RAP/natural aggregate unbound base mixtures

Transportation Geotechnics, 2019
This paper presents an experimental study to evaluate the effect of freeze-thaw cycles on the resilient modulus and permanent deformation of reclaimed asphalt pavement (RAP)/natural aggregate mixtures for the construction of unbound base layers.

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 ...
