In order to guarantee the service performance of recycling asphalt mixture with reclaimed pavement (RAP), rejuvenator shall be added. last five years, vegetable oil-based rejuvenators have received more and attention due their green regenerative advantages. The object this paper is investigate feasibility rejuvenating aged by a kind waste oil (W-oil). effect W-oil on characterized safety property test, aging tests; tests included traditional rheological test. results show that both...
Porous asphalt pavement has been used for multiple purposes, but its large porosity makes it easy to age by long-term weathering conditions; this causes premature failure through raveling, fatigue, and so forth. This study explored the fatigue performance of aged porous mixtures produced with epoxy binders. Gradations three were first designed in laboratory: (1) a mixture 13 an binder (EPA-13); (2) high-viscosity (HPA-13) as control; (3) dense-graded (HDA-13) another control. Then, tests...
This study investigates the relationship between void characteristics and sound absorption of an epoxy porous asphalt mixture. The specimens are scanned reconstructed under different fractions using X-ray computed tomography (CT) technology digital image processing, coefficients at frequencies obtained acoustic impedance tube. is analyzed gray correlation. test results exhibited a good correlation mixture by CT scanning (mesoscale) measured values (macroscale). difference fraction connected...
To examine the pyrolysis and combustion characteristics of epoxy asphalt, heat smoke release were analyzed via TG-MS cone calorimeter tests, surface morphology residual carbon after was observed scanning electron microscopy. The results showed that produce rate asphalt high in early stage, then sharply decreased. Moreover, total produced close to base presented an irregular network structure, which rough loose, had few holes, however most them existed form embedded nonpenetration. it is not...
Porous asphalt pavement have been widely employed for various functions. However, due to its large voids and small contact area between particles, the reflective cracks results from semirigid base layer shrinkage cracking buttom-up fatigue are easy occur, under long-term multifield coupling influenced by load, temperature, water, light other factors of natural conditions. Therefore, improving crack resistance is a key issue. Using an overlay test with high-viscosity porous mixture (HPA-13)...
The production process of the traditional paper making produces a large amount waste water, known as black liquor. It is needed to explore new ways reusing this and replacing part base bitumen reduce consumption non-renewable resources, such petroleum, thus obtaining better environmental, economic, social benefits. This analyses feasibility using liquor, which contains lignin, modifier for in industry. Samples modified were prepared with 15%, 30%, 45% replaced by control group was testing....
Abstract With offshore oil and gas developments moving into deep water, the size of mudmats foundations has been increasingly large, exceeding handling capacity installation vessels. The foldable design can effectively avoid constraints by stinger or moon pool. analytical numerical solutions undrained load-carrying shallow are mostly available for single (isolated) foundations, not feasible mudmats. bearing failure mechanisms depend significantly on foundation spacing soil strength profiles....
Abstract Acoustic sensitivity analysis is an essential technique to determine the direction of structural-acoustic optimization by evaluating gradient objective functions with respect design variables. However, acoustic impedance, which important parameter representing interior absorbent material in automotive acoustics, lacking study. Moreover, implemented conventional numerical methods time and effort-consuming due large-scale mesh generation. In this work, impedance for acoustics based on...
An effort was made to improve the separation issue of styrene-butadiene-styrene modifiers in styrene-butadiene-styrene-modified asphalt binders and further enhance their performance by adding nano-ZnO binder prepare compound modified binder. First, optimum dosage determined based on conventional tests, i.e., penetration, ring ball softening point, ductility at a fixed dosage; then, dynamic shear rheometer, bending beam fluorescence microscopy tests were conducted evaluate properties...
