Cyclic and Postcyclic Triaxial Testing of Ballast and Subballast
Journal of Materials in Civil Engineering, 2016AbstractBallast and subballast are two layers of noncohesive, granular materials with different grain sizes filled in the track substructure to bear traffic loadings from train passages. The performance and sustainability of a track substructure depend on both of these two granular layers. This paper presents the experimental results of cyclic triaxial

The specific deviatoric energy to liquefaction in saturated cyclic triaxial tests
Proc. of the 7th International Conference on Earthquake Geotechnical Engineering, 2019Within the European project LIQUEFACT, cyclic triaxial tests were carried out on an Italian sand, Pieve di Cento sand, taken from a field trial located in Emilia Romagna (Ita-ly), which was affected by liquefaction during the 2012 earthquake. The cyclic resistance curve of that sand was obtained in laboratory on reconstituted specimens with a low ...

Mechanical performance of recycled aggregates in cyclic triaxial testing
2017In Belgium, more than 6,000 t of recycled concrete and masonry aggregates are produced every year, coming from civil engineering demolition works. They contain up to 50% of masonry. It is allowed to recycle them in road bases and subbases if they satisfy the requirements set in the standard specifications.

Portuguese UGM characterisation using cyclic triaxial tests
2012Crushed materials with extensive granulometry – unbound granular materials (UGM) – are often used as unbound granular layers of road pavements, namely as granular sub-base and base. In spite of several studies having already been undertaken, the behaviour of these materials on pavement layers has not been sufficiently characterised, especially due to ...

A Review of Factors Affecting Cyclic Triaxial Tests
1978The effects of testing procedures and material characteristics on the cyclic triaxial strength of cohesionless soils were reviewed with the intent of categorizing the significance of these factors for cognizance in future testing standards. It was found that specimen preparation methods, differences between intact and reconstituted specimens, density ...

Soil Liquefaction Assessment by Anisotropic Cyclic Triaxial Test
2018Liquefaction of saturated sandy soils is one of the most significant aspects of earthquake triggered natural hazards. The main mechanism deals with the loss of effective stress due to rapid pore water pressure generation during earthquake shaking. This chapter involves with the fundamental mechanism and impacts of liquefaction.

Results of the cyclic triaxial testing on mechanically–biologically treated waste
Waste Management & Research: The Journal for a Sustainable Circular EconomyAccurate assessment of the dynamic strength characteristics of mechanically–biologically treated (MBT) waste is crucial for the construction and safe operation of landfill sites. Herein, samples of MBT waste from the Hangzhou Tianziling landfill were collected and subjected to consolidated undrained cyclic triaxial tests under four confinement levels ...

Cyclic Triaxial Tests at Low Stresses for Parameter Determination
1987ABSTRACT The results of 2 drained cyclic triaxial tests at low isotropic stress are presented. For the tests to be meaningful the effective stress paths have been controlled from the very beginning and systematic errors as membrane penetration, bedding error and membrane restraint have been taken into account.
