Embodiment 1
[0028] When the present invention is put into production, carry out according to the following steps:
[0029] 1) Calibration of non-nuclear density meter;
[0030] a) After the paving of each surface layer of the rubber asphalt pavement test road is completed and passed the inspection, 5 points are evenly selected and marked;
[0031] b) Start the non-nuclear density meter, set the representative value of the rubber asphalt surface layer thickness to be detected, and measure the density at the marked points in step a);
[0032] c) After step b) is completed, immediately drill the core sample at the corresponding position, and mark it well, and the mark corresponds to the number of the detection data of the non-nuclear density meter;
[0033] D) the core sample of step c) is drilled to measure the gross volume density of each core sample by surface dry method indoors;
[0034] e) taking step b) the measured density of the non-nuclear density meter as the abscissa, and taking...
Embodiment 2
[0040] In the rubber asphalt pavement test section of Guangdong Xingyu Expressway, when the present invention was put into the test, the following steps were carried out:
[0041] 1) Calibration of PQI non-nuclear density meter;
[0042] a) After the paving of each surface layer of the rubber asphalt pavement test road is completed and passed the inspection, 5 points are evenly selected and marked;
[0043] b) Start the PQI non-nuclear density meter, set the representative value of the rubber asphalt surface layer thickness to be detected, and measure the density at the marked points in step a);
[0044] c) After step b) is completed, immediately drill the core sample at the corresponding position and mark it, which corresponds to the PQI non-nuclear density meter detection data number;
[0045] D) the core sample of step c) is drilled to measure the gross volume density of each core sample by surface dry method indoors;
[0046] e) taking step b) the measured density of the...
