A mechanistic empirical approach for the evaluation of the structural capacity and remaining service life of flexible pavements at the network level
Road asset managers need to utilize reliable indicators for the structural condition and remaining service life at the network level to make rational decisions of the required funding and the optimum
Characterisation of Foam Bitumen Quality and the Mechanical Properties of Foam Stabilised Mixes
The use of foam bitumen stabilisation is rapidly growing worldwide because of its environmentally friendly benefits and its high field performance properties. The foam bitumen quality is assessed by
Effect of rheology on the bitumen foamability and mechanical properties of foam bitumen stabilised mixes
The use of foamed-bitumen stabilization technique is growing steadfastly and it is gaining wide spread acceptance in many different countries. This technique is new to New Zealand and it just has
New Zealand Experience with Foam Bitumen Stabilization
Foamed bitumen stabilization is burgeoning steadfastly and internationally. Although it involves higher initial material costs than cement or lime stabilization, it offers the advantages of being
Evaluating Nonlinear Elastic Models for Unbound Granular Materials in Accelerated Testing Facility
The characterization of unbound granular materials is particularly important in thin-surfaced pavements where most of the bearing capacity is provided by the granular layers. For an accurate modeling
Effect of Aggregate Gradation, Mineral Fillers, Bitumen Grade, and Source on Mechanical Properties of Foamed Bitumen-Stabilized Mixes
With the rapid growth of traffic volumes and axle loads, the use of efficient and cost-effective stabilization methods is imperative. The use of foam bitumen stabilization is rapidly growing because
Mechanistic Roughness Model Based on Vehicle-Pavement Interaction
A mechanistic roughness performance model that takes into account vehicle dynamics was developed for use in flexible pavement design and evaluation. The model was developed in the form of a relation
Multi-Scale Criteria for Structural Capacity Evaluation of Flexible Pavements at Network Level
The structural performance evaluation of the highway network is of significant importance for highway network asset managers. Pavement surface deflection has been used by several highway agencies to
Three-Dimensional Nonlinear Finite Element Model for Simulating Pavement Response: Study at Canterbury Accelerated Pavement Testing Indoor Facility, New Zealand
A three-dimensional nonlinear finite element model (3D-FEM) was developed as part of a study of the effect of increasing axle load and tire pressure on pavement deterioration. The measured strains,
