Thermoplastic polyurethane elastomers (TPUs) are widely used in a variety of applications as result flexible and superior performance. However, few scholars pay close attention on the design synthesis TPUs through self-determined laboratory process, especially definite chemical structures upon influence properties. To investigate properties synthesized modifier based structure, firstly each kind unknown structure composition ratio was determined by using new method. Furthermore, thermal...
The objective of this study is to expose the effect a variety variables including three reclaimed asphalt pavement (RAP) contents, two warm mix (WMA) additives and rejuvenating agent (or lack of) on performance WMA containing (WMA–RAP) materials. A laboratory was conducted evaluate WMA–RAP mixtures through rutting, bending freeze-thaw splitting tests. Analysis variance (ANOVA) performed analyse significant performance. tests results showed that increased RAP content led an rutting resistance...
The objective of this study aims to investigate the performance thermoplastic polyurethane elastomers (TPU)-modified asphalt, with special focus on influence synthesis parameters upon base asphalt. In study, TPU modifier was incorporated into asphalt prepare TPU-modified by using a self-determined laboratory process. properties polyester-based and polyether-based modified different contents analyzed tests. Fourier transform infrared spectroscopy (FTIR), fluorescent microscope, scanning...
This study fully intends to elucidate the mechanism of waste wood oil (WWO) modifier content on microscopic action bio-asphalt by utilising molecular dynamics simulations. Molecular models virgin asphalt and its components, WWO modifier, with different contents were created verified fluctuation parameters, radial distribution function (RDF), thermodynamics parameters. In addition, influence thermodynamic structural properties interactions between components was quantitatively evaluated...
The obvious nonlinear characteristics of fatigue damage accumulation for asphalt binders can be induced by variable amplitude loading. However, the corresponding are difficult to characterized due loading interaction and sequence. This study aims at characterizing (NFDA) establishing an NFDA model. First, stress-controlled time sweep tests with oscillation were conducted under two modes high-low stress (σhigh-σlow) low-high (σlow-σhigh). Then, was proposed using a crack length model, effects...
The grout pressure in the shield tunnel tail void during synchronous grouting is key to controlling ground settlement and restraining segment. However, circumferential, longitudinal, radial distribution of considering temporal variation viscosity has not been well explored yet. In this study, a theoretical model dissipation Bingham was established. simulation results were verified by field-measured data. showed that longitudinal distributions closer impacts main parameters on analyzed....
The fatigue life of asphalt mixture has been found to significantly depend on loading sequences. However, the widely used traditional linear equations are difficult determine subjected different This study aims improve these by establishing a equation considering sequence effects. First, semi-circular bending (SCB) constant amplitude tests were conducted under high (σhigh) and low (σlow) amplitude, respectively. Then, two sequences, namely low-high stress (σlow-σhigh) high-low (σhigh-σlow),...
This article designs a novel tunnel insulation liner material based on polyurethane foam (PUF), aiming to improve the material's mechanical properties, hydrophobicity, thermal properties and reduce self‐weight of material. Firstly, PUF is self‐made using one‐step method, optimal parameter combination optimized through single‐parameter (SP) method. Secondly, PUF, new process employed prepare polydopamine (PDA)/graphene oxide (GO)/PUF. Compression experiments contact angle tests are conducted...
Abstract Thermoplastic polyurethane (TPU) elastomer modified asphalt mastic is regarded as a two‐phase composite composed of TPU and filler according to the micro‐mechanics theory composites, its rheological properties are affected by various types asphalt, mineral filler, dosage. In this study, different kinds fillers (limestone, granite, fly‐ash, coal gangue) (grade base labeled 90# polyether‐based with C h = 40, r 1.05 through self‐determined laboratory process) were prepared into mastic....
