Investigation of marshall test parameters depending on bitumen percentage and temperature in asphalt coatings

When producing asphalt pavements, reducing both the harmful gases emitted to the environment and the energy consumed to bring the mixture to the desired temperature have been examined for years. In this study, the optimum bitumen content of 5,1% for dense grade asphalt pavements designed according to wearlayer type 1 is 3 levels be low and above (4.8-4.9-5-5.10-5.20-5,30-5,40) briquettes were prepared at 143 °C and 137 °C compression temperaturesand Marshall stability test was applied to them, yield in gand stability values were examined.As a result of the study, it was found that the compression temperature of 143°C gave a higher Marshall stability value than the compression temperature value of 137°C; Interms of yield values, it has been observed that the yield values increase with the increase of the bitumen ratio at higher values than the optimum bitumen ratio, and the compression temperature of 143°C gives lower yield values than the compression temperature value of 137°C.In the study, Marshall stability, Marshall flow, Airgap, Space between mineral aggregates, Space filled with asphalt, Marshall stability/Marshall flow rates were examined.
