Unified Mechanistic Approach for Modeling Tests of Unbound Pavement Materials

Journal of Transportation Engineering, 2012
AbstractSeveral tests are used for the characterization of unbound materials for pavement applications. The resilient modulus has been one of the most common tests for design specification of unbound materials. The California bearing ratio (CBR) is another laboratory test that is frequently used.

Normalized Characterization Model of Pavement Materials

1983
The principal objective of any pavement design procedure is to provide a structural system that will be suitable in a specific regional area and be able to sustain the anticipated traffic loading and frequency. The accomplishment of this objective and the utilization of the design procedure is highly dependent on its ability to predict future pavement ...

Pavement Design Model for Unbound Granular Materials

Journal of Transportation Engineering, 2004
This paper reports the results of several repeated load triaxial tests performed on a crushed rock aggregate at different stress levels. The development of the resulting permanent deformation that accumulates with the repeated loading is described and compared with the types of responses usually described by the shakedown approach. It is shown that the

The selection model of pavement material via grey relational grade

SMC 2000 Conference Proceedings. 2000 IEEE International Conference on Systems, Man and Cybernetics. 'Cybernetics Evolving to Systems, Humans, Organizations, and their Complex Interactions' (Cat. No.00CH37166), 2002
In road engineering asphalt concrete is the major material used in the pavement. In the past two decades, only two methods have been used to evaluate the pavement performance. The two methods used are the present serviceability index (PSI) and the present serviceability rating (PSR).

Resilient Modulus Predictive Model for Unbound Pavement Materials

Contemporary Topics in Ground Modification, Problem Soils, and Geo-Support, 2009
Data from 96 resilient modulus laboratory tests on four base materials and four subgrade soils was used to develop a predictive model capable of estimating changes in resilient modulus as a function of changes in the state of stress, moisture and density.
