“…In spite of the fact that the PG specifications require conduct of tests at a single frequency, the test can be repeated for a range of frequencies and is termed the "frequency sweep test". The frequency sweep test yields a number of parameters related to the bitumen being tested: complex modulus, viscous modulus, elastic modulus, and phase angle [16]. The operation of DSR is fairly basic during the frequency sweep test.…”

“…This oscillation is one cycle and is repeated for a specified number of cycles. The number of cycles completed in one second is the loading frequency [16]. In this study, shear stresses were applied on the specimen at different frequencies (10 Hz and 0.01 Hz) over a range of temperatures (from 40 °C to 80 °C, with an increment of 10 °C).…”

“…The calculated variances show that the rheological test results vary in acceptable ranges. In the Superpave performance grading system specification, G*/sin must be no less than 1 kPa for the unaged bitumen sample, and 2.2 kPa for the RTFO aged bitumen sample [16,19,28]. The high temperature performance grade of each bitumen sample is given in the Table 5.…”

“…The utilization of engine oil can provide advantages such as money savings, preservation of nature and natural resources, and reduction in environmental pollution [14,15]. Process oil is defined as a special engine oil that is used in a wide variety of chemical and technical industries either as a raw material component or as an aid to processing [14,16]. Process oil may also be used as bitumen extender, but addition rates of process oil are generally low in order to guarantee adequate performance of asphalt mixtures.…”

Rheological characteristics of bitumens prepared with process oil Depletion of natural and finite resources has necessitated the worldwide reuse of waste and residue materials from industrial production. Not only does the utilization of crude oil residue with bitumen allow supply of additives at a very low cost, but it also permits the use of waste and residue materials as rejuvenator in nature. The objective of the study is to evaluate conventional and rheological characteristics of original bitumen samples obtained from two different refineries involving different contents (1 %, 2 % and 3 %) of process oil (PO). The results show that PO can be used as an effective and environmentally friendly solution instead of commercially available expensive additives that are used in modification process.

“…They further concluded that the fry oil modification enhanced the self-healing properties of HMA at low temperatures. Xavier et al [22] utilized the used and virgin maize oil for binder modification. Their results showed that with the increase of maize oil content the elasticity was increased while the stiffness was reduced.…”

The pavement structure tends to shrink under low temperature conditions and cracks will appear upon crossing threshold binder stiffness. Decreasing the binder viscosity at such low temperatures, by introducing additional oil fraction (aromatics and saturates) in asphalt colloidal systems, may result in improved resistance to thermal cracking. A single multi-grade engine oil (5W30) was used in this study to analyze the rheological properties imparted to binders. Rotational Viscosity (RV) test revealed that after Rolling Thin Film Oven (RTFO) aging, fresh oil and waste oil have a similar effect on decreasing the viscosity of binder and construction temperatures, reducing them by 5~8 °C. Fourier Transform Infrared Spectroscopy (FTIR) test results showed an abrupt increase of carbonyl concertation when fresh engine oil was used for rejuvenation while waste engine oil was less susceptible to oxidative aging. Dynamic analysis of modified binders proved that engine oil has better thermal cracking resistance but relaxation ability of binders and rutting resistance was impaired. Filtered waste engine oil resulted in a 35% decrement in the stiffness of binder compared to virgin asphalt after short term aging but upper Performance Grade (PG) was compromised by 1~3 °C with 2.5% oil inclusion. Unfiltered waste engine oil proved to have the least overall performance compared to fresh and filtered waste engine oil.
