| Overview | petroleum asphalt has excellent plasticity and cohesiveness, rich resources, low price, it has a long history to be used as road paving materials. With the development of highway, the use of petroleum asphalt is also increasing. Due to the complex composition of asphalt, it is difficult to analyze the asphalt used at present. In recent years, infrared spectroscopy has received a certain degree of attention in the chemical structure analysis of asphalt, and has become one of the most commonly used microscopic analysis methods. |
| purpose | for road paving for road and construction works, can produce waterproof materials such as felt paper used for asphalt products, also used in the construction industry mainly used for waterproof joints |
