Asphalt binder is inevitably aged by ultraviolet (UV) light during its service period. UV ageing can significantly decrease the technical properties of asphalt binder. The sensitivity to and thermal-oxidative differs, such that performance cannot be determined based on performance. Previous researches mainly focused chemical composite changes ageing, parameters effect rate However, theory for characterizing explaining development depth does not get too much attentions, mechanism very clear....
The existing conductive asphalt concrete is not suitable for self-sensing of structural damage. In order to realize the perception electrical signals on damage pavement, A designed, and relationship between condition change resistance pavement established by adding multi-conductive phase materials ordinary concrete. influence different amounts additives volumetric parameters, properties, mechanical properties has been studied, volume parameter changes variability was clarified, correlation...
The low RAP content, hot mixing conditions, and the addition of a high ratio new bitumen aggregates result in economic environmental benefits for current regeneration technologies. A bio-rejuvenated additive (BRA) that can fully (100%) regenerate without heating is proposed this paper. To reveal mechanisms BRA-rejuvenated RAP, effects BRA on chemical structure molecular weight were investigated using Fourier-transform infrared spectroscopy gel permeation chromatography. mechanical...
The UV aging of bitumen has a significant influence on the pavement service life, therefore, research attracted increasing attention recently. It is known that bituminous pavements does not occur instantly through full depth, instead, depth increases gradually with time. limitation development mechanism clearly known. Various thicknesses membranes were prepared and light transmission absorption properties investigated by UV–visible spectrophotometric, aiming to determine penetration in after...
Ultra-thin overlays (UTOL) are a standard highway pre-maintenance method used to improve the road surface performance of asphalt pavements and repair minor rutting cracking. However, thin thickness makes it very sensitive external changes, which increases its wear shortens life. So, this paper aims prepare durable skid-resistance ultra-thin overlay using epoxy (EA) steel slag. First, physical properties EA were characterized by penetration, softening point, flexibility, kinematic viscosity...
The special environment conditions in high altitude areas leads to serious cracking and peeling of road hot-melt marking coatings. In order improve the durability paint, a durable paint was designed by modifying with toughening-agent, rheological agent, anti-aging agent. modification mechanism modified coating revealed through TG FTIR analysis. low-temperature anti cracking, adhesion, properties were studied bending test, interlaminar shear test UV aging test. Besides this, workability...
Green production of asphalt materials is very important to promote energy savings and emission reduction during the construction maintenance pavement. A low-temperature additive (LCA) made from waste plastic rubber proposed, which belongs a class environmentally friendly additives for mixtures. Marshall stability was tested evaluate mechanical performance LCA-modified mixtures (LCA-AMs). In order determine best preparation parameters LCA-AMs, influence content LCA addition method on strength...
In order to improve the viscoelasticity of bitumen, several modifiers were compounded with it, including SBS, reclaimed rubber powder, tackifier, plasticizer, and oil stabilizer, produce High-viscosity High-elastic Modified Bitumen (HVE-MB). The various physical rheological properties bitumen evaluated using a number factors, such as dynamic viscosity at 60 °C, elastic recovery, penetration, softening point, ductility, DSR. By comparing different types content it was found that original...
To meet the needs of road industry for maintenance operations, a new cement emulsified bitumen mixture (CEBM) with early-strength, self-compacting, and room-temperature construction characteristics was designed. The strength formation mechanism CEBM revealed scanning electron microscope (SEM) surface free energy (SFE) theory. mechanical properties performance were investigated extensively. results show that before demulsification bitumen, SFE bitumen-aggregate-water three-phase system...
A self-compacting steel slag epoxy resin concrete (SERC) was designed with as aggregate and binder for rapid repair of road expansion joints pavement. At the same time, a group basalt (BERC) coarse limestone fine set up control group. The element analysis micro morphology SERC BERC were studied by X-ray fluorescence spectrometry (XRF) scanning electron microscope (SEM) to reveal strength-forming mechanism two concretes. cube compression test Marshall stability used study effect strength...
Pyrolysis carbon black (PCB) is the surplus product of waste tires after pyrolysis. Polyethylene (PE) main component disposable plastic bags, and synthetic plant ester (SPE) an environmentally friendly plasticizer that has recently emerged. In this study, aforementioned three materials were used to prepare composite-modified asphalt (CM-A). The fatigue performance PCB-modified (PCB-A) was improved through compound modification with PE SPE plasticizer. optimization formulation design...
