Structure Strength

The rapid growth of road traffic brings some requirements on driving comfort and safety, which include good smoothness, skid resistance and reduced noise of the pavement. SMA has adequate structure strength to reduce rutting and provide superior surface function of skid resistance. Modified asphalt as mixture binder, has considerable durability to ensure the service life with less maintenance costs. Associated with laboratory test and trial section, some suggestion and requirements are brought forward in this paper for the material properties and mixture design of SMA on the FuZhou-JiAn expressway in Jiangxi Province.

Biomechanical Features

The periodontal ligament (PDL) is a soft connective tissue which exhibits an inhomogeneous, nonlinear, and anisotropic material properties. and the elastic modulus of different positions on each section are not the same, analysis of the material properties of PDL enables a better understanding of biomechanical features for tooth movement. The aim of this study was to study the elastic modulus of different section of PDL in nanoindentation. Experimental results indicate that the average elastic modulus elastic modulus in midroot are lower than cervical margin and apex, and there is large change in the circumferential regions.

The One

Grain boundary segregation is the process by which solute elements in a material diffuse to the grain boundaries, become trapped there, and increase their local concentration at the boundary over that in the bulk. As a result of this process this local concentration of the segregant at the grain boundary can be many orders of magnitude greater than the bulk concentration of the segregant. The importance of this problem lies in the fact that grain boundary segregation can affect many material properties such as fracture, corrosion, and grain growth.One of the best ways to study grain boundary segregation is with Auger electron spectroscopy. This spectroscopy is an extremely surface sensitive technique. When it is used to study grain boundary segregation the sample must first be fractured intergranularly in the high vacuum spectrometer. This fracture surface is then the one that is analyzed. The development of scanning Auger spectrometers have allowed researchers to first image the fracture surface that is created and then to perform analyses on individual grain boundaries.

Property Changes

This brief review seeks to summarize some of the main property changes which may be induced by altering the grain structure of materials. Where appropriate an interpretation is given of these changes in terms of current theories of grain boundary structure, and some examples from current studies are presented at the end of this paper.
