  • Method and system for detecting road intelligent compaction index
    Patent number: 12139859
    Abstract: A method and system for detecting road intelligent compaction index, so as to solve the problem of inaccurate use of a road intelligent compaction index due to the fact that existing harmonic ratio indexes do not consider the influence of a non-integral period on the accuracy and also do not consider a higher harmonic. According to the disclosure, a relative relationship between amplitudes of the higher harmonic and a fundamental wave in an acceleration time domain signal is considered based on the related art, the amplitude of the higher harmonic is introduced into a main body road intelligent compaction index of an road intelligent compaction index, and a precondition for the use of the road intelligent compaction index of the main body is established, that is, a machine-material decoupling control the machine-material decoupling control index.
