A satisfactory bituminous mix should have aggregate gradation, which will ensure maximum density and minimum voids in the mix to fulfill requirements of bituminous mix design specifications. In India organizations such as Indian Roads Congress and Ministry of Surface Transport (MOST) [1] have laid down specifications regarding the range of percentage passing of different size of aggregate in th...

Resilient modulus and California Bearing Ratio (CBR) in unbound granular materials are the key technical characteristics of layers in a flexible pavement design. Among the factors affecting these two parameters, the aggregate gradation is the most important. Using particle size distribution curve developed by AASHTO, together with other considerations mentioned in the related regulations have y...

Finite Elements in Analysis and Design ()-This paper gives a status on anisotropic mesh gradation. We present two 3D anisotropic formulations of mesh gradation. The metric at each point defines a well-graded smooth continuous metric field over the domain. The mesh gradation then consists in taking into account at each point the strongest size constraint given by all these continuous metric fiel...

This paper presents a new approach to the semantics of spatial degree and comparison (gradation) expressions (e.g., 2m less long than). Taking a broad cognitive science perspective, results of different research fields are combined into a cognitive framework for the ‘semantics of gradation’ (Bierwisch 1989). A distinction between implicitly and explicitly represented aspects of space will be ma...

Koskenniemi’s two-level morphology was the first practical general model in the history of computational linguistics for the analysis of morphologically complex languages. In this article we will reconsider one of the key innovations in Koskenniemi (1983), namely the treatment of consonant gradation in finite state transducers. We will look not at Finnish, but at two languages with a more exten...

This article focused on the stress analysis of an edge crack in a thin hallow rotating functionally graded material (FGM) disk. The disk is assumed to be isotropic with exponentially varying elastic modulus in the radial direction. A comprehensive study is carried out for various combinations of the crack length and orientation with the different gradation of materials. The effect of non-unifor...

The paper presents an a priori procedure to control the element size and shape variation for meshing algorithms governed by anisotropic sizing specifications. The field of desired element size and shape is represented by a background structure. The procedure consists in replacing the initial field with a smoothed one that preserves anisotropic features and smaller element sizes. The smoothness ...
