1. IMPLEMENTATION OF TRAFFIC IMPACT ASSESSMENT IN DEVELOPING COUNTRIES: CASE STUDY OF BANGLADESH

Authors: MD. SHAMSUL HOQUE , NUZHAT AZRA

Abstract: Due to unplanned development, traffic congestion in the cities of Bangladesh has become a serious problem. As a result, Traffic Impact Assessment (TIA) has become a necessity to control this unplanned growth. In Bangladesh, the concept of TIA has recently been introduced and is yet to be institutionalized. Here implication of TIA faces many challenges which are also common in most of the developing countries. In this paper, the issues and challenges are discussed as well as the possible solutions. The study further discusses the strategies for improving implementation of TIA in Bangladesh.

Keywords: implementation process, issues and challenges, land use plan, traffic impact assessment.

2. EXPERIMENTAL STUDY ON SLOPE EROSION CONTROL USING STRAW FIBER TECHNOLOGY EXPERIMENTAL STUDY OF SURFACE RUNOFF WITH RAINFALL INTENSITY EFFECTS AND DIFFERENT SLOPE GRADIENT ON THE SLOPE EROSION RATE FOR SILTY SAND SOIL

Abstract: This study aims to analyze the influence of surface runoff with rainfall intensity and different slope on the rate of slope erosion that occurs in silty sand soil. The results of the study with 3 variations rainfall intensity of 50 mm / hour, 100 mm / hour and 120 mm / hour, indicating that the effect of surface runoff on rainfall intensity and slope gradient on soil erosion rate is directly proportional. The amount of erosion that occurs based treatment in the laboratory on surface runoff discharge with successive rainfall intensity I50, I100, and I120 at 10° slope respectively are 26285 ml/hour = 36,608 gram/m2/hour, 63375,5 ml/hour = 53,500 gram/m2/hour and 87239,5 ml/hour = 54,150 gr/m2/hour. At the slope of 20°, for surface runoff with successive rainfall intensity I50, I100, and I120 amount of erosion respectively are 34292,5 ml/hour = 4,100 gram/m2/hour, 63375,5 ml/hour = 13,550 gram/m2/hour and 88170 ml/hour = 94,150 gram/m2/hour. Then for the slope of 30°, due to the increment

3. THE INFLUENCE OF FIBER ON THE CHANGES OF MICRO STRUCTURE OF POROUS CONCRETE ASPHALT MIXTURE

Authors: HERMAN PARUNG , MUH. NASHIR T , TRI HARIANTO

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.

Keywords: porous concrete asphalt, fiber, micro-structure

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
