WebBBR; PG Verification with MP1a Analysis. Same as PG verification with the addition of the Direct Tension test and the BBR at two temperatures. This combination of tests provides a more in-depth low temperature property analysis. Direct tension data is incorporated with that of the BBR to determine compliance with critical cracking requirements. WebDec 24, 2014 · Operated at room temperature, this shield enables specification of the BBR environment to a corresponding fractional clock uncertainty contribution of 5.5×10−19. Combined with uncertainty in the atomic response, the total uncertainty of the BBR Stark shift is now 1×10−18.

WebThe DTT is used in combination with the BBR to determine an asphalt binder’s low temperature PG grade determination. As with other Superpave binder tests, the actual temperatures anticipated in the area where the asphalt binder will be placed determine the test temperatures used. Figure 1: Direct Tension Tester. Figure 2: Direct tension tester. WebJan 1, 2024 · The BBR tests were performed at two different low temperatures (−15 and −25 °C). The standard procedure as described in EN 1477 was followed [7]. All measurements were carried out after an equilibrium period of 1 h at the test temperatures. rd 3100 cartridge and needle

However, determination of the BBR temperature via population transfer can be done on the faster timescale t therm = 1/(Γ 01 + 2Ω 01). This is illustrated in figure 2 where we model the SrF system in a 300 K BBR field. rd awnings
