Embodiment 1
[0039] A) the comparison SBS modified asphalt sample is composed of a calibration set and the infrared spectrum data of the contrast SBS modified asphalt sample is collected;
[0040] Among them, different qualities of SBS (the product of LG501 produced by South Korea’s LG Chemical) were added to the base asphalt (the product of Shell AH-90 produced by Shell China), and 12 samples with evenly distributed SBS content were prepared. The SBS content of the SBS modified asphalt samples were 3.0%, 3.3%, 3.6%, 3.9%, 4.0%, 4.2%, 4.5%, 4.7%, 5.0%, 5.3%, 5.7%, 6.0%. Select 10 of them as the calibration set samples (i.e., select 10 of them as the reference SBS modified asphalt samples to form the calibration set), and measure the attenuated total reflection infrared spectra of these control modified asphalt samples respectively (i.e., use the attenuated total reflection method Determination of the infrared spectrum data of these contrast SBS modified asphalt samples), wherein the corres...
Embodiment 2
[0050] A) the comparison SBS modified asphalt sample is composed of a calibration set and the infrared spectrum data of the contrast SBS modified asphalt sample is collected;
[0051] Among them, different qualities of SBS (the product of LG411 produced by Korean LG Chemical) were added to the base asphalt (the product of SKAH-90 produced by SK of South Korea), and 12 SBS with uniform distribution of SBS content were prepared. Modified asphalt samples, the SBS content were 3.0%, 3.3%, 3.6%, 3.9%, 4.0%, 4.2%, 4.5%, 4.7%, 5.0%, 5.4%, 5.7%, 6.0%. Select 10 of them as the calibration set samples (i.e., select 10 of them as the reference SBS modified asphalt samples to form the calibration set), and measure the attenuated total reflection infrared spectra of these control modified asphalt samples respectively (i.e., use the attenuated total reflection method Determination of the infrared spectrum data of these contrast SBS modified asphalt samples), wherein the corresponding SBS co...
