In this research study, the binder is modified by 2, 4, 6, and 8 percent of NC, and two important distresses of asphalt, rutting and fatigue, are evaluated through the LAS, MSCR, 4-point bending beam, and dynamic creep tests.
The samples were compacted using a Gyratory compactor for the dynamic creep, indirect tensile strength, and resilient modulus tests.
Considered here in this section is an attempt to relate some of the conventional mix tests results (dynamic creep and resilient modulus) to fatigue response.
Therefore, resilient modulus test might be a more reliable test in evaluating the fatigue performance of asphalt mixtures as compared to dynamic creep test, or simply the significance of mixture cohesion in contributing to the fatigue resistance of asphalt is more important than mixture internal friction.

This article presents rut and dynamic creep
test results of concrete, SMA (stone mastic asphalt), MNU (thin courses of noncontinuous grain mixtures), Superpave mixture and porous asphalt mixture of two air void content percentages: 15 %, 20 %.
The mechanical properties tested were indirect tensile stiffness modulus (ITSM) at 20[degrees]C , dynamic creep
at 40 [degrees]C, and fatigue at 20[degrees]C .
In this article, the physical properties of compounds using WMB are compared with dry-mixing compounds, and the characteristics of WMB are investigated by means of the spin-spin relaxation time, the fracture surface energy and the dynamic creep
Union Carbide will describe a dynamic creep
durability lab test apparatus to measure the comfort and durability of automotive molded foam.
Accordingly, a conventional binder test, storage stability, rotational viscosity, dynamic shear rheometer (DSR), and repeated creep and recovery (RCR) tests were performed on neat and modified bitumen and marshal stability, and dynamic creep
and wheel track tests were performed on asphalt mixtures.
and Rubberised Asphalt Shear deformations resulting from high shear stresses in the upper portion of bituminous layer appear to be the primary cause of rutting in flexible pavements.
Figure 1 shows a schematic diagram explaining the relationship between the accumulated permanent deformations and the loading cycles in the dynamic creep
tests using the Universal Materials Testing Apparatus (UMATTA).
