This paper deals with the modeling of rolling resistance and analysis effect pavement texture. The Rolling Resistance Model (RRM) is a simplification no-slip rate Dynamic Friction (DFM) based on tire/road contact intended to predict tire/pavement friction at all slip rates. experimental validation this approach was performed using machine simulating tires road surfaces. tested surfaces have wid...

Runway surface conditions are fundamental to ensure safety during landing and takeoff operations of aircrafts. In this manner, airport operators required monitor the coefficient friction macrotexture runways maintain its plan maintenance rehabilitation strategies when appropriate, since both these parameters get deteriorated with time. Thus, assist aerodrome regulatory agencies in decision-maki...

Multiscale modeling for cement-based materials, such as concrete, is a relatively young subject, but there are already a number of different approaches to study different aspects of these classical materials. In this paper, the parameter-passing multiscale modeling scheme is established and applied to address the multiscale modeling problem for the integrated system of cement paste, mortar, and...

In recent years, the Lamb wave analysis by the multi-channel analysis of surface waves (MASW) for concrete structures has been an effective nondestructive evaluation, such as the condition assessment and dimension identification by the elastic wave velocities and their reflections from boundaries. This study proposes an effective Lamb wave analysis by the practical application of MASW to concre...

We analyze the concrete security provided by a signature scheme described in a recent Internet Draft by McGrew and Curcio.

This paper presents an experimental study on circular stirrup-confined concrete specimens under uniaxial and monotonic load. The effects of stirrup volume ratio, stirrup yield strength and concrete strength on damage evolution of stirrup-confined concrete were investigated. The experimental results showed that the strength and ductility of concrete are improved by appropriate arrangement of the...
