In order to evaluate volatile organic compounds (VOC) from asphalt, this paper explored to use ultraviolet and visible spectroscopy (UV-VIS) as the detection method of VOC. 288nm wavelength was selected as the characteristic absorption wavelength of VOC, finding that VOC quality and its absorbance value showed a good linear relationship which could be the basis for evaluation in this research. Experiments were carried out under different conditions, results of which showed that VOC emission was related to temperatures and asphalt specimens. Moreover, VOC emission increased with increasing temperatures. Results under non-high temperatures conditions showed that VOC emission during its service process should not be ignored.
