Ceramic fiber, with a major composition of Al₂O₃ and SiO₂, has advantages of stability at relatively high temperature, big specific surface area and resistance to external mechanical vibration. It has the potential contribution of improving the rutting resistance and temperature sensitivity of modified asphalt binder by proper modification design. In this research, ceramic fiber was introduced ...

La floculation des asphaltnes est dŽcrite comme une transition thermodynamique conduisant ˆ la formation d'une nouvelle phase liquide riche en asphaltnes : le dŽp™t asphaltŽnique. Le modle thermodynamique choisi est l'Žquation d'Žtat de PengRobinson associŽe aux rgles de mŽlange d'Abdoul et PŽneloux fondŽes sur les contributions de groupes. Le brut est reprŽsentŽ par 33 pseudo-constituants....

This paper describes the Accelerated Testing with the LINTRACK-facility of the innovative ‘Rollpave’ test pavement that was developed within the theme ‘Modular Pavement Structures’ of the project ‘Roads for the Future’ of the Dutch Ministry of Transport, Public Works and Water Management. The concept of ‘Rollpave’ is a thin pre-manufactured asphalt wearing course that is rolled on a reel. On si...

Waste cooking oil (WCO), in many cases, can rejuvenate aged asphalt and restore its properties. However, the influence of WCO qualities on rejuvenation behaviors of aged asphalt has not been investigated in detail. The objective of this paper was to evaluate the effects of WCO viscosity and acid value on the basic, rheological, and chemical properties of a typical rejuvenated asphalt. Penetrati...

With the increasing awareness of environmental protection and attention to resource reuse, development high-performance degradable green biomass pavement materials attracts a lot interest. Lignin bio-oil effectively combined play synergistic role can improve various properties asphalt partially replace petroleum-based asphalt. Therefore, this paper aims study rheological aging bio-oil/lignin co...

Of the $150 million USD pledged for the Strategic Highway Research Program (SHRP), approximately one-third ($50 million USD) is designated for Asphalt Binder Research. The SHRP program is a fiveyear, highly focused, product-oriented research effort. The goal of the asphalt portion of the program is to issue a new binder and mixture specification that will help federal, state and local regulator...

The effect of modification asphalt concrete mixtures different grain sizes with “Ric-Polycell” (Ukraine) and “Duroflex®-SMA” thermoplastic polymers (Germany), which were added directly to the mixer during their preparation, on properties was studied. It is confirmed that it more expedient use stone mastic concretes a larger size mineral crushed grains high-traffic roads, as they are rutting-res...

This paper describes a fast procedure for evaluating asphalt pavement surface defects using airborne emissivity data. To develop this procedure, we used airborne multispectral emissivity data covering an urban test area close to Venice (Italy).For this study, we first identify and select the roads' asphalt pavements on Multispectral Infrared Visible Imaging Spectrometer (MIVIS) imagery using a ...

Asphalt is considered a colloidal material and it is important to study the relationship between its colloidal structure, chemical components and performance. The aromatic nucleus content of asphalt at different depth analysed by attenuated total reflection (ATR) was taken as the index of colloid structure. The gray correlation was used to analyse the relationship between colloidal structure an...

This study demonstrates the use of Class F fly ash in combination with lime or lime kiln dust in the full depth reclamation (FDR) of asphalt pavements. FDR, in the context of this paper, is a process of pulverizing a predetermined amount of flexible pavement that is structurally deficient, blending it with chemical additives and water, and compacting it in place to construct a new stabilized ba...
