Abstract

A process to improve the properties of reclaimed polyethylene (RPE) polymer modified asphalt mixture by grafting of maleic anhydride (MAH) onto RPE (RPE-g-MAH) in the presence of dicumyl peroxide (DCP) as initiator was proposed. Fourier transform infrared spectra (FTIR) was employed to verify the grafting of MAH onto RPE. Modified asphalt mixture under different conditions were investigated on the RPE-g-MAH samples. To assess the effects of the RPE-g-MAH on the high-temperature stability of modified asphalt mixture, we discussed dynamic stability (DS) and rutting depth (RD) of modified asphalt mixture by studying the influences of various experimental parameters such as MAH content, DCP content, mixing temperature, wet mixing times and gradation type of mixture. Experimental results indicated that the RPE-g-MAH is feasible to improve high-temperature stability performance and low-temperature performance of asphalt mixture, and it could dramatically improve resistance to rutting of the asphalt mixture. Possible mechanism was proposed for RPE-g-MAH modification of asphalt mixture.

Abstract

To improve the power factor and reliability for medium/high-power supply, a three-phase single-stage ac–dc converter based on magnetic-combination transformer with power factor correction (PFC) function is presented in this paper. According to the three-phase instantaneous power balance principle and the concept of the magnetic-flux superposition, a novel magnetic-combination transformer is proposed, which can make three-phase symmetrically and sinusoidally fluctuant power add to be constant. Therefore, the induced voltage of the secondary winding is constant. To realize sinusoidally fluctuant power in the input stage, dc-link filter capacitance can be reduced to a several-microfarad level. Single-stage PFC function, no electrolytic capacitor, and constant output voltage can be realized in the converter. The principle and the structure of the novel magnetic-combination transformer are analyzed in detail in this paper. Simulation and experimental results are presented to verify the feasibility of the proposed converter. [ABSTRACT FROM AUTHOR]
