Fundamental Analysis of Aggregate Interlock
Journal of the Structural Division, 1981A model for aggregate interlock has been developed based on the behavior of micro scale. The relation between displacements and stresses across the crack faces are defined to be a function of deformation and sliding at particle level. This relation is derived for one particle projecting from one of the crack faces with an arbitrary diameter and an ...

Constitutive modelling of aggregate interlock in concrete
International Journal for Numerical and Analytical Methods in Geomechanics, 2002AbstractA model for formed cracks in concrete is presented. The model can be used in isolation for existing cracks or linked with other damage or plasticity models and applied once a crack has fully formed. It can be applied directly to interface finite elements or used to control the behaviour of crack planes in more general constitutive models that ...

Load Transfer Characteristics of Aggregate Interlocking in Concrete Pavement
Journal of Transportation Engineering, 2009This paper presents a finite-element model of a jointed concrete pavement with aggregate interlocking load transfer system. Interlocking mechanism has been modeled by a set of discrete springs. A new parameter “modulus of interlocking joint ( Kj ) ” has been introduced to represent the load transfer characteristics of the interlocked joint.

Effect of particle interlock on flow of aggregate through opening
Powder Technology, 2014Abstract Blockage of concrete flow through opening or gap often occurs during placement of self-consolidating concrete due to particle interlock of coarse aggregate particles. Suggestions to reduce the coarse aggregate content in order to minimize such particle interlock have been made by some researchers.

The Mechanical Properties of an Interlocked Low-Porosity Aggregate
Géotechnique, 1968Synopsis If coarse grained marble is heated to around 6OO°C the anisotropy of thermal expansion of calcite causes almost complete separation at grain boundaries. The resulting material retains its shape and consists of a mass of crystals in contact, with a porosity of about 4%, very small direct tensile strength and the mechanical analysis and ...

New design method for best aggregate packing or interlocking mechanism
2011 National Postgraduate Conference, 2011The gradation of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. In hot mixture asphalt (HMA), gradation helps determine almost every important property. The gradation that produces maximum particle interlock, maximum packing density, maximum strength, desirable air voids ...

AGGREGATE INTERLOCK IN HIGH STRENGTH REINFORCED CONCRETE BEAMS.
Proceedings of the Institution of Civil Engineers, 1988Tests are reported on aggregate interlock in reinforced concrete beams which have web reinforcement and are made of high strength concrete. High strength concrete is here defined as concrete which has a strength in excess of 6000 lbf/sq in (41 n/sq mm).

Analysis of aggregate interlock behaviour at cracks in reinforced concrete
Magazine of Concrete Research, 1988Synopsis Analytical methods have been developed for predicting the resistance provided by aggregate interlock against sliding-shear deformations at cracks in reinforced concrete. These methods are shown to be capable of predicting test results with a reasonable accuracy, and they are used for an analytical study of the influence on aggregate ...

Load Transfer through Aggregate Interlock: Crack Width, Aggregate Type and Performance
Proceedings of the International Conference on Concrete PavementsIt is well known that performance of plain jointed concrete pavements depends on aggregate interlock to transfer load from the one slab to the next. In order to quantify the relative contribution of crack width and the strength of the aggregate to the long-term performance of a plain jointed pavement, experimental sections of road were built using ...

Characterization of aggregate interlocking in hot mix asphalt by mechanistic performance tests
Road Materials and Pavement Design, 2021The interlocking of aggregate is critical during compaction. Nevertheless, few mix design specifications include any specific requirements for locking points, mainly because it is difficult to dete...
