Bridge Deck Pavement

Epoxy asphalt concrete, mortar asphalt concrete and Gussasphalt concrete are commonly used types of deck pavement materials in bridge deck pavement engineering. However, achieving the high-temperature stability and anti-fatigue performance of the deck pavement materials is still challenging. In order to reduce the rutting and cracking risks of the asphalt mixture, this paper proposed pre-coated aggregates grouting asphalt concrete (PGAC) for bridge deck pavement. Laboratory tests were conducted to determine the optimum grouting materials and to evaluate the mechanical performances of the PGAC material. Test results showed that the mechanical properties for PGAC with grouting material of high-viscosity-modified asphalt binder blending with mineral filler were superior to that of GMA-10 used for the Hong Kong-Zhuhai-Macau Bridge deck pavement. Microstructural analysis showed that the PGAC had a more stable skeleton structure compared to other typical aggregate mixtures. This study highlights the performances of the proposed PGAC and sheds light on the deck pavement material improvement of both high-temperature stability and anti-fatigue performance that could be achieved.

Focus on destruction features of the rigid-flexible composite pavement interlayer, Crumb rubber modified asphalt, SBS and crumb rubber composite modified asphalt, SBS modified asphalt were prepared. High temperature stability performance, medium-temperature fatigue performance and adhesive property of three knds of interlaminar material were evaluated and compared. Test results show that high temperature PG grade of SBS and crumb rubber composite modified asphalt is PG82, which showed better high temperature stability. Moreover, crumb rubber modified asphalt has more soft at normal temperature which benefited to medium-temperature fatigue performance. Besides, SBS and crumb rubber composite modified asphalt possesses better interlaminar adhesive property with 60°C viscosity is 2430Pas. So SBS and crumb rubber composite modified asphalt is recommend as spraying asphalt material in rigid-flexible composite pavement interlayer, the results can provide certain reference.

Silicon Based

The present study is focussed on the oxidation behavior of nonoxide silicon-based ceramics. Various Si3N4 and SiC ceramics were examined after long term oxidation tests (up to 5000 h) at 1500°C in ambient air. The damage mechanisms were discussed on the basis of a comprehensive chemical and microstructural analysis of the materials after the oxidation tests. The diffusion of oxygen into the material and its further reaction in the bulk of the material were found to be the most critical factors during long term oxidation treatment at elevated temperatures. However, the resulting damage in the microstructure of the materials can be significantly reduced by purposeful microstructural engineering. Using Si3N4/SiC and Si3N4/MoSi2 composite materials provides the possibility to improve the high temperature stability. [S0742-4795(00)00301-X]

And Performance

This study presented the preparation and performance of a kind of high viscosity and elastic recovery asphalt (HVERA) by using some modifiers. The performance of styrene-butadiene-styrene (SBS), rock asphalt (RA), crumb rubber (CR), and stabilizing agent (SA) for different modifiers was investigated by conventional binder test. Effects of modifiers on the high- and low-temperature properties of HVERA were investigated. The dynamic viscosity (DV) test, dynamic shear rheometer (DSR), and bending beam rheometer (BBR) analysis indicated that the high- and low-temperature rheological properties of asphalt were improved attribute to the addition of mixture of modifiers. Meanwhile, the short-term aging and long-term aging were simulated by rolling thin film oven (RTFO) and pressure aging vessel (PAV) tests. Furthermore, the Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) measurements were conducted for obtaining the mechanism and microstructure distribution of the modified asphalt binders. From the test results in this study, it was evident that the addition of SBS, RA, CR, and SA into a neat asphalt binder could both significantly improve the viscosity of the binder at high temperature and lower the creep stiffness at low temperature, which was beneficial to better both high-temperature stability and low-temperature cracking resistance of asphalt pavements. It was proved that the high temperature grade of HVERA could be increased by increasing of RA and a proper percentage of modifiers could be improved by the low temperature grade of HVERA.

Die Attach

The operation of electronic packages in high temperature environments is a significant challenge for the microelectronics industry, and poses a challenge to the traditional temperature limit of 125°C for high electronic systems, such as those used in down-hole, well-logging and aero-engine applications. The present work aims to develop understanding of how and why attach materials for Si dies degrade/fail under harsh environments by investigating high temperature Au based solders. Au-2wt%Si eutectic melts at < 400°C and offers high temperature stability but high temperature processing and complex manufacturing steps are the major drawbacks. Changes in the die attach material were investigated by isothermal ageing at 350°C, thermal shock and thermal cycling treatments. Die attach reliability investigated by thermal shock and thermal cycling showed that the bonded area degraded. Nevertheless, most of the samples tested had high bonded area ranging from 92.5 to 97.5%. The failure behaviour of the die attach materials included cracking of die and/or attach material, delamination and voiding. Scanning acoustic microscopy images provided a rapid assessment of delamination and other defects and their location within the package. Microstructural analysis and die shear testing were also carried out, along with the high temperature endurance of a SOI test chip for signal conditioning and processing applications at 250°C. All functions evaluated have shown stable performance at 250°C for up to 9000 hours.

Highway Tunnel

This paper used the method of spread the broken glass and light-colored stone into the asphalt mixture, then rolling to compact, to increase the brightness of the asphalt pavement in highway tunnel. Through a series of tests, we have studied the performance of the light-colored asphalt pavement, including high temperature stability, anti-sliding performance, impermeability, bond performance and the light-colored performance. Experimental studies have shown that the anti-sliding performance, high temperature stability will be lower slightly compared to ordinary asphalt concrete. Its impermeability has increased. The light-colored performance is better. At the same time, after the analysis of the experimental results we know that the improvement of light-colored performance is not only effected by the dosage of the materials, but also has a great relationship with the particle size. In general, the smaller the particle size of the materials joined, the more apparent the light-colored performance improved.

According to high temperature weak stability of common asphalt mixture, rutting tests of diatomite modified asphalt mixture, modified lake asphalt mixture, modified rock asphalt mixture and common asphalt mixture are carried out. Changes of dynamic stability for common asphalt mixture compared with modified asphalt mixtures are comparatively analysed. The results show that compared with common asphalt mixture, rutting resistances of diatomite modified asphalt mixture, modified lake asphalt mixture and modified rock asphalt mixture are greatly improved. It is proposed that those kinds of modified asphalt mixture are adopted in asphalt pavement of large longitudinal slope section.
