| Abstract: | Different samples of road dust are taken in Nanjing city. Corresponding experiments on particle diameter and elemental components of these samples are performed to obtain distributions of particle diameters, elemental components and levels. Low-calorie-value of arrived basis and fractal dimension of road dust are computed and analyzed where lowcalorie-value of arrived basis ranges from 5 385.0 kJ/kg to 7 366. 6 kJ/kg and fractal dimension fluctuates between 2. 302 and 2. 541. This provides fundamental information for direct energy utilization and sanitary landfill of road dust. |
