bio modified asphalt

2 · 2 · In summary, the R value of rock asphalt modified bio-asphalt is better under a low-stress level (0.1 kPa), and the R value of different types of bio-oil asphalt is sensitive to changes in the amount of bio-oil. The sensitivity of RASOO is the most sensitive to bio-oil content, while soybean oil is the least sensitive to bio-oil content.

10%· Sep 05, 2019· Asphalt binders modified with bio-oils derived from various biomasses have been developed for addressing pavement sustainability and environmental concerns. This study evaluated the bio-binders modified with bio-oils derived from waste cooking oil, and was aimed for the chemical and rheological characterization under different oxidative aging conditions and the aging susceptibility of the bio ...

To prepare the bio-oil modified asphalt binders, the bio-oil and control asphalt binder were heated to 110 and 130°C, respectively. Then, the bio-oil and control asphalt binder were blended using a high shear mixer at 120°C for 20 minutes with a speed of 5000 revolutions per minute.

Apr 04, 2018· This study investigates and evaluates the storage stability of asphalt binder modified by bio-oil at high temperature. Five bio-asphalts are prepared by adding 10, 15, 20, 25, and 30% bio-oil into 70# petroleum asphalt. The bioasphalts are statically stored for 48 h at four different temperatures: 120, 140, 160, and 180°C.

Sep 19, 2018· Bio-modified asphalt mixes are highly elastic even at lower temperatures than unoriginal mixes. Overall bio-modified asphalt can be a promising applicant for low-temperature behavior. However, further modification of bio-modified asphalt for higher temperature is essential to increase its performance against rutting.

May 30, 2019· May 30, 2019· A neat base asphalt binder was modified using 0%, 1%, 3%, and 5% bio-oil that was derived from waste cooking oil as a by-product of the biodiesel production process. The frequency sweep and LAS tests were performed to determine the linear viscoelastic rheological and fatigue properties, respectively.

Nov 30, 2020· The bio-modified asphalt has a superior low-temperature and intermediate-temperature performance, while, its high-temperature performance varies depending on the type and dosage of the bio-oil used to modify asphalt binder. Correspondingly, the bio-modified asphalt mixture has a better low-temperature crack resistance and fatigue resistance ...

asphalt binder from scrap tire rubber and bio-binder is investigated in this paper. The newly developed bio modified rubber is a hybrid viscoelastic thermoplastic adhesive composed of ambient crumb rubber and bio-binder. Bio-binder is produced from thermochemical conversion of swine manure, and crumb rubber is obtained from grinding of scrap tire.

Jul 30, 2017· 3.4. Preparation of SBS modified bio-asphalt. In order to have a better compatibility, SBS and base binder were mixed by using a high-speed shear emulsifying machine for 15 min at 180 °C, while keeping the rotation speed of 3000 r/min.Then, bio-oil was added into SBS asphalt and mixed with the high shear mixer for 20 min with a rotation speed of 3000 r/min.

However, bio-modified asphalt binders have shown varying performance regarding susceptibility to moisture damage; some bio-oil modifiers significantly increase asphalt binder's susceptibility to moisture damage. This variability in performance is largely due to the large number of bio-masses available for use as sources of bio-oil, as well as the

Sep 04, 2020· Thus, the nano-particles might also provide a positive modified effect on the high-temperature performance of bio-asphalt binders. Based on this, five types of nano-particles including SiO2, CaCO3, TiO2, Fe2O3, and ZnO are selected for the preparation of modified bio-asphalt binders, using different dosages of nano-particles and bio-oil.

SBS modified asphalt was prepared by a FM300-DIGITAL shearing machine (Motlong, Wenzhou, China). First, 3 portions of base asphalt were taken, then melted at 175 °C. Adding 3%, 4% and 5% SBS modifier, base asphalt was sheared with a shearing machine at 3000 r/min for 1 h, heated to 180 °C, and then stirred with a mixer for 1 h.WPU/SBS composite modified asphalt was prepared by the process.
