Stone Mastic Asphalt Pavement Technology for the New Millennium
Since the 1960s, Stone Mastic Asphalt (SMA) pavement surfaces have been used successfully in Germany on heavily trafficked roads. Because of its excellent performance characteristics, road authorities in Germany as well as major European Countries quickly adopted SMA as a standard wearing course. As a consequence of an asphalt study tour in Europe of an American delegation in 1990, SMA test sec...
متن کاملMacroscopic constitutive law for Mastic Asphalt Mixtures from multiscale modeling
A well established framework of an uncoupled hierarchical modeling approach is adopted here for the prediction of macroscopic material parameters of the Generalized Leonov (GL) constitutive model intended for the analysis of flexible pavements at both moderate and elevated temperature regimes. To that end, a recently introduced concept of a statistically equivalent periodic unit cell (SEPUC) is...
متن کاملEvaluating the Performance of Hot Mix Asphalt with Reclaimed Asphalt Pavement and Heavy Vacuum Slops as Rejuvenator
Due to the high price of crude oil, and consequently asphalt binder, the application of Reclaimed Asphalt Pavement (RAP) in pavement technology is widely considered. The present paper is the result of a laboratory research which was carried out to investigate the effects of adding a rejuvenating agent to Hot Mix Asphalt (HMA) with RAP. To this end, test samples comprised of Aged Asphalt Binder ...
متن کاملStone mastic asphalt: assessing the effect of cellulose fibre additives
& Currently, in the UK, there is considerable interest in the fact that a German bituminous surfacing mixture known as stone mastic asphalt may possess levels of in-service performance that resist the growing incidence of premature failure experienced by traditional materials such as hot rolled asphalt. A high stone content grading requires the use of a stabilizing additive to ensure long-term ...
متن کاملRobust molecular micro-capsules for encapsulating and releasing hydrophilic contents.
The hydrophobic-amphiphilic self-assembly approach has been employed to prepare molecular micro-capsules simply by cooling down an emulsion, in a hot polar solvent medium, of a melted compound having two very well-distinguished units, both with highly non-polar and hydrophobic characteristics. The resulting micro-capsules are very stable and robust both in suspension and under dry conditions. F...
