Abstract: The use of additional material such as fibers in concrete asphalt mixture may affect the micro structure of the mixture. The micro-structural change is identifiable by the existence of various sub-atomic particles. In general, the study aims to investigate the effect of fibers addition on the micro-structural atomic changes in porous concrete asphalt mixture with asphalt material of oil-based (penetration of 60/70) and of polymer asphalt stabilised with polypropylene. The study was carried out by performing a test on samples by means of XRD (X-ray diffraction) and SEM (scanning electron microscope). The study shows that the petroleum-based asphalt pen 60/70 has compound elements of Carbon (C70), Cyclo-octasulphur monoxide (S8O) and Cristobalite beta (SiO2), while the petroleum-based asphalt pen 60/70 enhanced with polypropylene fibers has compound elements of Carbon (C70), Cyclo-tris(suphur VI)oxide with chemical formula of SO3, Cristobalite beta (SiO2), and Carpathite compound C24H12.

Abstract: The concrete structures might reach up to the highest inner temperature 1,400℃ of the structures when there is a fire. At this time, there could be spalling phenomenon as a feature of concrete and fatal damages like falling off in structure stability and durability because of the temperature increase in main reinforced bar. In the research, by using fireproof board containing silicon compound as a base with flame retardants has been tried to verify the possibilities of securing the structural stability, durability, and fire resistance. To make it possible, analysis on thermal feature and the performance of fire resistant were carried out with manufactured specimens which is silicon compounds produced through the changes of weight ratio of 25~40wt% with silicon compounds like ATH, MDH, and MC. As the result, all the specimens were separately verified as to its excellence for fire resistance and the possibility that could make stability, durability, and performance of fire resistance sec
