Fatigue cracking characterisations of waste-derived bitumen based on crack length
نویسندگان
چکیده
This study aims to characterise fatigue cracking of two types waste-derived (bio-oil and LDPE) bitumen. Modified Paris’ law Griffith criterion were proposed investigate crack propagation initiation the Results show that bio-oil delays LDPE accelerates initiation, bitumen itself dominates unaged The did not take effects in altering bitumen’s performance after pressure ageing vessel (PAV) ageing. PAV-aged modified is more prone phase, but it remains same rate as control

An Outrun Competition of Corrosion Fatigue and Stress Corrosion Cracking on Crack Initiation in a Compressor Blade
First row rotating blades of four axial-flow compressors were prematurely fractured. Previous investigations showed that the site atmosphere contains corrosive compounds which lead to an increase in possibility of pitting on the blades. It was also revealed that the crack was originated from two corrosion pits. Thus, this work is conducted to ascertain which of fatigue or stress corrosion crack...
متن کاملCharacterization of Bitumen Mixed with Plastic Waste
Plastic (Polyethylene Terephthalate, PET) is now used as packaging material for a whole range of consumer products in addition to carbonated beverages. Although plastics are very useful product, but the disposal of these wastes has become a problem and is of great concern, particularly in our country. One of the solutions to the disposal of plastic wastes is recycling it...
متن کاملModeling of Corrosion-Fatigue Crack Growth Rate Based on Least Square Support Vector Machine Technique
Understanding crack growth behavior in engineering components subjected to cyclic fatigue loadings is necessary for design and maintenance purpose. Fatigue crack growth (FCG) rate strongly depends on the applied loading characteristics in a nonlinear manner, and when the mechanical loadings combine with environmental attacks, this dependency will be more complicated. Since, the experimental inv...
متن کاملData-driven Fatigue Crack Evaluation based on Wave Propagation Data
8 This project presents a machine learning based fatigue crack sensor 9 evaluation scheme without using a physical model. A supervised binary 10 classification problem is defined to distinguish damaged steel specimens 11 from intact specimens. Sets of time-series wave propagation data collected 12 by the fatigue crack sensor are utilized for the proposed scheme. In order to 13 apply supervised ...
متن کاملRheological properties of modified Bitumen: Comparison of waste polymers’ performance
In this investigation, rheological properties of three different polymer-modified bitumen compounds containing recycled polyethylene terephthalate (R-PET), crumb rubber (CR) and poly (styrene-butadiene-styrene) (SBS) are evaluated and compared. The modified samples were tested by a dynamic shear rheometer (DSR) where complex modulus (G*), phase angle (δ) and rutting resistance (G*/Sinδ) of spec...
