Abstract. 4H-SiC thyristors are of particular interest in pulsed power applications due to their ability to block high voltages and transfer high current densities along with fast switching times.
Introduction Silicon carbide high power thyristors constitute the most promising switching device technology for pulsed power which potentially also could find their application in the civil domain, e.g., in HVDC distribution systems [1].

Keywords: Pavement management system, HDM-4, highway, threshold.
The road engineering changes the style from new construction to maintenance management.
Although the government invests a large amount of money in maintaining highways, the area highway authorities determine necessity and priority only by engineers’ experience.
HDM-4 road work affects the mode of adjustment: Through highway maintenance manual, freeway maintenance manual, and the common construction method as the basis for the selection of representative engineering methods.
According to HDM-4 road work affects model to explore the differences and representative engineering methods final construction method setting of effectiveness and costs. 4.
