The meaning of BINDER COURSE is a coarse aggregate bound with bitumen between the foundation and the wearing course of an asphalt pavement.
The utility model relates to a road surface structural style that mats formation mainly solves the road surface overhaul, the rebuilding stage, carry out the road surface structure of recycling to old and useless pavement material, and specifically speaking is a half flexible binder course of ...
Durability evaluation of OGA mixture ensures longer service life and adequate abrasive resistance as CGB mixes are intended to be used in the wearing course. To ensure adequate durability, the abrasion loss is restricted to 20 % [48,71,72]. In a study, the researcher calculated approximate ...
To investigate the influence on rolling noise of incorporating a high content of CR to a gap-graded pavement by wet process, different sections of a road were rehabilitated. A wearing course of gap-graded mixture prepared with CRMB (experimental section) and the same type of mixture without cr...
Additionally, bio-oils decreased the environmental impact of the binder up to 37.46mPt, and 8.33% in the ReCiPe, and Intergovernmental Panel on Climate Change analysis, respectively. Therefore, the exploitation of bio-oils in the pavement market can be considered as promising green solution for ...

This paper documents the second part of a forensic investigation performed to determine the causes of loss of skid resistance and bleeding in two pavement sections rehabilitated with an ultra-thin bonded wearing course. The first part of the study explored the influence of the aggregate fraction on...

HMA mixtures are prepared for wearing course. The nominal maximum aggregate size is selected as 12.5 mm. Table 1 shows the standard aggregate test results. Silica nano powder In this study, silica nano powder (SiO2NP) is used to modify bitumen. Typical properties of SiO2NP is shown in Table...
In addition, bituminous binders are difficult to handle and require specific technologies.Therefore, for roadways and in particular the wearing course, the main constituents are bituminous concretes consisting of approximately 95 weight % aggregate and approximately 5 weight % bitumen used as binder. In...
