Sentence examples for high temperature grade from inspiring English sources
In contrast, the low temperature grade of the binder PG 76-22 and the high temperature grade of the RAP binder were restored with the use of the tested rejuvenator product.
For the asphalt binders and HMA evaluated, the MSCR showed a better correlation with the two rutting related performance tests (HWTT and RLPD) than the DSR high temperature grade.
As theoretically expected, the corresponding results indicated that addition of RAP and RAS significantly improved the Dynamic Shear Rheometer (DSR) high temperature grade of all the extracted asphalt binders, with most of the HMA mixtures exhibiting relatively low Jnr values in the multiple stress creep recovery (MSCR) test.
The true low and high temperature grades of the extracted binders were determined using the Dynamic Shear Rheometer (DSR) and the Bending Beam Rheometer (BBR) tests.
In order to characterize the properties of the asphalt binder related to HMA rutting, the Superpave performance grade system uses the high-temperature grade, which is determined based on the complex shear modulus (|G∗|) and phase angle parameter (G∗/sinδ) that is measured from the Dynamic Shear Rheometer (DSR) test.
The high temperature performance grade changed and low temperature performance grade kept unchanged after modification, the PG 64-22 basphalthalt binder changed into PG 76-22 for base asphalt binder with 5% WTR and 2% RPE and PG 82-22 for base asphalt binder with 10% WTR and 2% RPE.
The main objectives of this paper are to demonstrate how mix testing and binder results can be used to estimate the high temperature performance grade (PG) of warm mix asphalts (WMA) with and without bio-based additives and to compare dynamic modulus performance between different asphalt binders and select bio-based additives.
The results indicate that prediction of high temperature performance grade for an asphalt mixture cannot be done using the Hirsch model, but is possible using the Al-Khateeb model and that the additives and non-modified binder were not found to be statistically different from one another overall as well as within each binder type.
The PPA and HDPE were found to only increase binder stiffness (i.e., reduced penetration number, non-recoverable compliance and increased high temperature performance grades) whereas the EMA-GMA also improved the binder elasticity (i.e., increased elastic recovery and strain recovery values).
That was combined with upgrading the main pack contractor to use inconel (a high temperature space-grade superalloy) instead of steel, so that it remains springy under the heat of heavy current.
In this study, the ability of five asphalt binder rejuvenators to restore low and high temperature true performance grades of aged binders was investigated.
