Bioasphalt - helloscholar

The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. The components of asphalt include four main classes of compounds:

Combustion mechanism of four components separated

2017-3-15  TG/DSC test results of four components separated from asphalt binder. From Fig. 1, a relatively small endothermic peak on DSC curve of each component is observed at around 100 °C. This is because a small amount of water contained in component sample experiences a thermal evaporation process [14]. It is seen that the endothermic volatilizations ...
