Embodiment Construction
[0015] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0016] refer to figure 1 , a method for detecting bitumen and bitumen modified additives according to the present invention, the method includes the steps of: scanning step S1: scanning and collecting the infrared spectrum of the bitumen sample and / or the bitumen modified additive sample. Specifically, the infrared spectrum of qualified samples can be collected by the HF-03 asphalt rapid analysis instrument produced by CPT (Beijing) Technology Co., Ltd. Set the parameters to the wavelength range of 650 ~ 4000cm -1 , resolution 4cm -1 , the number of scans is 32 times. After turning on the instrument and warming up for 30 minutes, take the measurement. First, clean the crystal surface of the instrument with a cotton swab, and collect the background; then apply the asphalt sample evenly to the crystal surface, and the sample needs to cover an...
