Asphalt Mixture Design Concepts to Develop Aggregate Interlock
… it was desired to understand the interaction of aggregates, asphalt, and the voids created during their compaction. In asphalt mixture design, guidance is lacking in the selection of the design aggregate structure and understanding the interaction of that aggregate structure and mixture …

Aggregate Interlock Behavior of Large Crack Width Concrete Joints in PCC Airport Pavements
Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2001.

Analysis of slab-on-grade pavement systems subjected to wheel and temperature loadings
… Temperature and wheel loadings are considered. Aggregate interlock and dowel bars may be taken into account as load transfer devices at the joints or cracks.

Application of Fracture Mechanics to Assess Reflective Cracking Potential in Airfield Pavements
… mode I loading associated, higher degree of aggregate interlock across PCC joints did not directly contribute to the reduction of critical overlay responses. Due to the stiff underlying rigid pavement, the critical overlay responses were relatively unaffected by quality of subgrade support.

Numerical Simulation of Reinforced Concrete Subjected to Multiaxial Stress Conditions
… nonlinear behavior caused by cracking, crushing, aggregate interlock, bond slip, dowel action, shrinkage and creep. Because the reinforced concrete involves so many nonlinear phenomena interacting with one another, the formulation of a "complete" analytical model is very difficult. The focus of …

Analytical model for reinforced concrete under cyclic loading
… which dominate the pre-cracking response, aggregate interlock, dowel action and bond slip come into the picture of the post-cracking response.

The Strength of Reinforced and Prestressed Concrete Beams Subjected to Combined Bending, Torsion and Shear
… modes (3 cases) The effect of dowel action, aggregate interlock, uncracked concrete and spacing of stirrups on the resistance of app]. icd torque have been examined. The predictions of the proposed theories have been compared with more than a thousand test results available in literature. In …

The mathematical modelling of concrete constitutive relationships
… addition to factors such as cracking, crushing, aggregate interlock, creep, shrinkage, bond slip and rate of loading. Analytical methods have been improved in the past two decades as a result of the availibility of more powerful computers. It is, therefore, feasible to model these nonlinear …

Shear strength and bearing capacity of reinforced concrete deep beams
… are also investigated. It is found that interlocking stirrups at small spacing are the most effective form of reinforcement. A failure mechanism for a concrete block in bearing is proposed and found to give the best estimate as compared with other models by different researchers. The …

Discrete element modeling of railroad ballast using imaging based aggregate morphology characterization
… and load distribution. In general, ballast aggregates are considered as uniformly graded, angular shaped with crushed faces. However, various ballast aggregate gradations and particle shapes are in use yet their effects on ballast performances remain unknown. In previous designs and modeling …

Development of Novel Computational Simulation Tools to Capture the Hysteretic Response and Failure of Reinforced Concrete Structures under Seismic Loads
… calibrated to account for the contribution of aggregate interlock resistance across inclined shear cracks. Validation analyses are presented, for quasi-static and dynamic tests on RC columns and RM walls.

Performance-based evaluation of unbound aggregates affecting mechanistic response and performance of flexible pavements
Unbound aggregates are widely used in road construction to replace unsuitable soil, prepare pavement working platform or construct pavement foundation layers. Their primary function in flexible pavements is to distribute wheel loads and provide adequate protection of the subgrade. However, the …

Engineering properties and structural behaviour of high strength reinforced concrete beams
… in order to optimise HSC mixes using local aggregates. The effect of different factors such as w/c ratios, silica fume and superplasticizer dosages on compressive strength and splitting tensile strengths in the range of 80 to 120 N/mm<sup>2</sup> (MPa) were studied. Additionally, new …
