Although the universal definition of MEMS product possesses a number of distinctive features, they are miniature systems involving one or more micro-mechanical components or structure. Infrastructure assessment has recently addressed an important field for MEMS application. For example, satisfactory laboratory experiment in the area of concrete monitoring has been developed. Although the experi...

todays applying concrete structures is more usual than other structures which are used in buildings as in most of the world’s countries the application ratio of concrete to steel has increased from 10 to 1. sometimes these structures require strengthening vulnerable members because of deficiency in their loading system in usual and critical conditions. there are different methods for strengthen...

The pavement industry relies greatly on this conventional material in constructing the road. However, shortage of mined has led to need finding alternative with local materials partially substitute asphalt components. also contributed thermal and greenhouse emission resulting from mining activities. In addition, throughout year, amount construction demolition (C&D) waste generated civil activit...

Using nano-technology materials in the asphalt pavement industry is new compared with Portland cement concrete. The main objective of this study is to investigate the effects of nano-silica modification on some properties of a penetration grade asphalt cement and a typical asphalt concrete. 60/70 penetration grade bitumen was modified with different percentages of nano-silica (i.e. 1, 3 and 5%,...

Abstract Due to the high demand for natural aggregates in pavement construction, researchers have been looking alternative materials replace aggregate. In this research, optimum binder content of asphalt mixture incorporate limestones was investigated. The tested according Marshall method. About 20 % limestone used as aggregate replacement asphaltic concrete mixture. To determine stability, vol...
