None of those States recognized that the asphalt they were getting included REOB. One State urged its examples had no REOB - https://www.easel.ly/browserEasel/14465169.

The highest possible level was 34 percent in a sample from Texas, which TxDOT had utilized in a patching substance. This screening also disclosed the existence of phosphoric acid in 11 percent of the samples, and 2 percent contained ground tire rubber.


2 years ago at TRB's annual meeting, the Federal scientists held an REOB workshop and provided the searchings for of their research laboratory analyses to a standing room-only group.

The sidewalk with REOB, which lies 0.6 mile (1 kilometer) from the pavement without REOB, has the same subgrade, web traffic density, and environment. The sector of Highway655 with 5 to 10 percent REOB showed substantial splitting. In this example, the existence of REOB was the identified root cause of cracking at a low temperature levels.

An area of test sidewalk in Minnesota (MN1-4) located to have REOB likewise fractured prematurely. The sidewalk done well for the first 3 to 4 years, yet then started to split.

The tests were not extensive, but they revealed that at levels of 6 percent or even more, the tensile strength of the asphalt dropped substantially. At a degree of 3.5 percent REOB, the variation in the physical test methods was more than the effect of REOB. As a matter of fact, it was tough for scientists to assess whether REOB existed.

One binder specification considered is the distinction in between the low temperature level crucial requirements temperature for rigidity (S) in the bending beam rheometer and the bending beam rheometer creep incline (m-value) noted as Tcritical. 2 independent research study teams, one from AASHTO and the various other from the Asphalt Institute, wrapped up that more research is needed on the usage of REOB in asphalt.


Previously, all asphalt screening measured engineering buildings such as rigidity. These tests do not reveal what products had been contributed to the asphalt. One sample gotten during the TFHRC study had a very get more strange evaluation. The example had the adhering to test results: Superpave PG 64-28 with a high temperature level grade of 67.3 Tcritical on the bending beam rheometer was 6.7 levels Celsius.

The addition of 1.7 percent phosphoric acid likely would make the asphalt extremely tight. 19percent REOB would certainly soften it and bring it back within spec.
