The invention discloses a kind of methods for identifying asphalt quality using decaying In situ ATR-FTIR standard spectrogram, including：Obtain 3 groups of repeatability infrared spectrums and 6 groups of reproducibility infrared spectrums, to obtain standard IR spectrogram, sample to be tested infrared spectrum is compared with standard IR spectrogram, to obtain relevance threshold, judges whether the quality of matrix pitch sample to be tested is qualified according to relevance threshold.The present invention is from the essential structure of pitch, and by carrying out full spectral region comparison to pitch, quick Identification Evaluation pitch screens the adulterated pitch of mix and convert, strong guarantee is provided for the monitoring of construction quality.In addition, the invention avoids a large amount of cumbersome road surface data and environmental factors complicated and changeable, it detects faster, experimental result can be provided within three minutes, data are accurate and reliable, it can be detected in mobile laboratory and scene, breach the limitation of traditional macro performance evaluation means, asphalt quality is timely and effectively monitored especially suitable for construction site. |
