Two research engineers from different operation offices performed automatic extraction of asphalt binder on three (3) different asphalt mixtures: recycled asphalt shingles (RAS), and two (2) Hot Asphalt Mixes (HMA) of Nominal Maximum Aggregate Size (NMAS) of 9.5mm and 25.0mm. Both mixes included 15.0% of Reclaimed Asphalt Pavement (RAP).

methods include a reflux extraction and recovery and penetration tests for the extracted binder and a modified Marshall stability, moisture susceptibility, and asphalt pavement analyzer (APA) tests for the mixtures. The shingle addition causes stiffer binder in the mixture, resulting in the increase of material

reflux extraction), asphalt analyzer and AASHTO T 308-ignition test. To accomplish this, several laboratories from Wisconsin along with the NCAT lab participated in the study. A total of eight mixes that included mixes and mixes with various contents of recycled binder were evaluated to quantify the variability in the determination of their

Automatic solvent extractors separate and calculate the binder content in an asphalt mix in an accurate, fast and safe way, thanks to its fully sealed technology. This environmentally friendly solution emits no solvent in the laboratory and makes it possible to recycle 99% of the solvent after the extraction .

Overview WRI's Asphalt and Petroleum Technology (APT) group is a leader in asphalt, petroleum, coal and hydrocarbon research. The group has several decades of experience leading research at the federal level to characterize, diagnose and predict asphalt and heavy oil properties and performance, and thermal processing of heavy oils.

EN 12697/1 - ASTM D8159- - AASHTO for the safe extraction of recycling asphalt and determination of the binder content using

Our automatic asphalt mixer is designed and made as per ASTM D2172 Standard test method for quantitative extraction of asphalt binder from asphalt mixtures. It is suitable to determine bitumen content (bitumen-mineral aggregate ratio) in the bituminous mixture, which

the samples should be stored in a deep freeze cabinet until the extraction can be made. This procedure will retard hardening of the asphalt during the time which elapses between taking the sample and extraction of the asphalt. 9. Any available new methods of test on the asphalt and paving mixtures should be utilized. 4 ~~~~-----

Extraction Equipment. Extraction processes (more precisely: solid-liquid extraction process) are used to separate components from a solid sample. The objective of all extraction processes is to dissolve as much of the soluble components as possible with a specific amount of solvent.

Analysis of asphalt and bitumen and their additives at the refinery ensures that they meet the specifications. Anton Paar’s measuring instruments and dedicated asphalt testing solutions deliver valuable insights into material properties which affect processing of your asphalt and bitumen, such as long-term stability and consistency, as well as behavior in storage and during transportation.

Meanwhile, the thickness of the asphalt surface layer specified by Malaysian PWD is divided into two layers, namely, the wearing layer and the binder layer, and the range of each layer is 0.04 to 0.05 m and 0.04 to 0.1 m, respectively. Taking into account these two layers as the surface layer of asphalt, the range obtained is 0.04 to 0.14 m.

2.1 Asphalt Binder The asphalt binder used for this study was obtained from the Hudson Companies located in Providence, RI. Three different Performance Graded asphalt binders (PG 64-28, PG 70-28 and PG 76-28) were used. Binder specification tests were performed to check whether the obtained asphalt binders were within the specification limits
