... influence of plastic sources on LVE behavior, whereas a significant effect is observed in the NLVE domain. Among the four modified bitumen types (LDP, LDF, LDPU, and LDS), LDPU exhibits superior resistance to permanent deformation, whereas LDF shows higher elasticity at high temperatures. Additionally, LDS...

... from the standard MSCR test and linear amplitude sweep (LAS) test to analyze both binder permanent deformation and fatigue cracking. This study was conducted with a PG (Performance Grade) 64-28 neat binder and three levels of styrene-butadiene-styrene (SBS) modification by weight of the binder: 2 %, 3...

... is evaluated in terms of fatigue life and resilient flexural modulus. The damage to the modified mixtures was also examined utilizing permanent deformation accumulation and degradation of resilient flexural modulus during a fatigue test. To ensure the same packing of aggregate mixture, the natural aggregate...

... soils exhibit low levels of plastic deformation. Thus, to allow more appropriate analyses of the mechanical behavior of such soils compared to traditional CBR-based analyses, resilient modulus and permanent deformation tests using RLT test equipment were performed. Then, multifactorial regression...

...Alaa M. Shaban; Paul J. Cosentino The permanent deformations of unbound pavement layers are typically caused by the movement and densification of aggregate particles under the influence of repeated wheel loads. This type of distress, which represents one of the major failure modes in flexible...

This paper presents the testing results of different combinations of steel slag, dolomite sand waste, and local limestone aggregates that were proportioned to develop a mixture that would satisfy the requirements of permanent deformation and fatigue. Analysis...

.... The laboratory experimental program included triaxial shear strength, dynamic (complex) modulus, repeated load permanent deformation, fatigue, crack propagation, and indirect tensile strength tests. The data was used to compare the performance of the fiber-modified mixture to the control. The results showed...

The MDD results showed that the sequence of repetitive aircraft gear loads with different wander positions used at NAPTF led to contractive/dilative permanent deformation behavior, especially in the unbound pavement layers. The magnitudes of MDD residual responses were dependent on the position...
