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.

Abstract: The disclosure discloses a high-viscosity, high-elasticity, and anti-aging composite modified asphalt and a preparation method thereof, belongs to the technical field of road engineering materials, and solves the technical problem that the comprehensive performance of an existing asphalt ultrathin wearing layer needs to be further improved so as to prolong the service life of a pavement surface layer and reduce the pavement maintenance costs. The composite modified asphalt is prepared from the following components in parts by mass: 100 parts of a matrix asphalt, 10 to 15 parts of a thermoplastic styrene-butadiene rubber, 5 to 8 parts of a tackifier, 0.5 to 1.5 parts of a plasticizer, 2 to 5 parts of a compatibilizer, 0.1 to 0.4 parts of a stabilizer, and 0.01 to 0.05 parts of an anti-aging agent. The composite modified asphalt prepared by the disclosure has the advantages of high elasticity, high viscosity, excellent aging resistance, etc.
