Embodiment 1
[0024] A pull-out test method for ultraviolet light aging asphalt and asphalt mortar, which selects Shell 70# base asphalt and rubber asphalt as research objects, and specifically includes the following steps:
[0025] (1) Thermal aging of asphalt and asphalt mortar samples
[0026] Put the asphalt and asphalt mortar samples into the oven, and control the temperature of the oven to 163°C for 5 hours;
[0027] (2) UV aging of asphalt and asphalt mortar samples
[0028] Put the asphalt and asphalt mortar samples into a circular sample pan (r60mm), the thickness of the sample is 1mm, and the circular sample pan is divided into high strength (r=0~20mm) and medium strength (r=0~20mm) with the center of the circle as the center. r = 20 ~ 40mm), low intensity (r = 40 ~ 60mm) area, the highest ultraviolet light intensity is 400W / m 2 , the masses of asphalt and asphalt mortar were 1.31g, 3.66g, and 6.14g, respectively. A 125w reflective high-pressure mercury lamp is used as the ultr...
