A method for fast detecting pavement asphalt and early warning based on infrared spectrum data. Infrared spectrum data of standard sample asphalt is collected by adopting an infrared spectrometer, to establish an infrared spectrum database of standard sample asphalt. The infrared spectrum database of the standard sample asphalt and basic asphalt information is introduced into a cloud server through a spectrum input module. A database-matching calculation method and a threshold value is set through a spectrum-matching analysis module. The infrared spectrum data and engineering information of the tested asphalt is collected and uploaded to a cloud platform for storage. A matching calculation between the uploaded data and the spectrograms in the infrared spectrum database of the standard sample asphalt through the cloud server is conducted. An asphalt matching result is outputted to a display terminal. An early-warning message is pushed by the cloud server if a test result is not-match.
