Embodiment Construction
[0031] The embodiment of the SBS modified asphalt dosage test method based on liquid chromatography provided by the present invention is as follows, it should be understood that this embodiment is only illustrative and non-restrictive, and those skilled in the art have the ability to further improve on this embodiment Modified to meet actual needs, therefore, this embodiment is not intended to limit the protection scope of the present invention.
[0032] A kind of SBS modified asphalt dosage testing method based on liquid chromatography, comprises the following steps:
[0033] (1) Prepare 3%~6% SBS modified asphalt samples respectively
[0034] Select the SBS modifier, and prepare 3% to 6% SBS modified asphalt samples through the process of stirring, shearing, and development. For example, first take 4 parts of 1kg of ordinary asphalt, and after the ordinary asphalt is heated to 180 ° C, respectively Add 1301SBS modifier with 3%, 4%, 5%, and 6% of asphalt quality, stir with a...

The invention discloses a liquid chromatography-based SBS modified asphalt dosage test method, and belongs to the technical field of material detection. The method comprises the following steps: carrying out liquid chromatographic scanning on an SBS modified asphalt sample solution with different dosages, carrying out baseline correction on obtained chromatograms by using an SBS modified asphalt liquid chromatogram optimum baseline area integration technology, and detecting the SBS modifier chromatographic peak area of every standard sample; and establishing a relationship between the SBS modifier chromatographic peak area and the SBS dosage to form an SBS modifier dosage standard curve. The method is used for controlling the dosage of SBS modified asphalt with an unknown dosage in labs, indoor production and onsite use places. The method solves the problem of unable segmentation of continuous chromatographic peaks through chromatographic software, has high precision in detection of the SBS modified asphalt dosage, and is a simple and effective treatment method.
Description
technical field [0001] The invention belongs to the technical field of material detection, and in particular relates to a method for testing the dosage of SBS modified asphalt based on liquid chromatography. Background technique [0002] With the rapid development of my country's economy, the traffic volume has increased rapidly, and the phenomenon of large-scale vehicles and overloading is still serious. Ordinary asphalt can no longer meet the requirements of the road surface. More and more roads use polymer-modified asphalt to improve road performance. , to avoid early diseases such as rutting and cracks, and prolong the service life of the road. [0003] Modified asphalt is the use of various measures to improve the performance of base asphalt. It is generally a mixture of base asphalt and one or more modifiers through appropriate processing technology. Commonly used modifiers are mainly divided into rubber and resin. , thermoplastic rubber, etc. [0004] SBS is a common...
