specific Embodiment approach 1
[0045] Specific implementation mode 1: This implementation mode is a method for evaluating the frost resistance of semi-rigid base material by using dynamic compressive resilience modulus, which is specifically completed according to the following steps:
[0046] 1. Determination of the dynamic compressive rebound modulus of the comparison specimen:
[0047] ①. Use the static pressure method or the vibration method to make a cylindrical comparison test piece with a diameter of 150mm and a height of 150mm according to the "Test Regulations for Highway Engineering Inorganic Binder Stable Materials" JTGE51-2009, and then test it at a temperature of 18°C to 22°C and Curing for 90 days at a relative humidity of 95% to obtain a comparison specimen;
[0048] ②. Divide the circumference of the cylindrical section at a distance of 2.5cm from the upper end of the comparison test piece into three equal parts, and then mark the three equal points to obtain three upper marking points; at...
specific Embodiment approach 2
[0084] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the temperature of the low temperature box described in Step 2 ②(2) is -18°C~-18.5°C. Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0085] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: step 1. adopts static pressure method or vibration method in accordance with "Highway Engineering Inorganic Binder Stable Material Test Regulations" JTG E51-2009, making A cylindrical comparison test piece with a diameter of 150mm and a height of 150mm was cured for 90 days at a temperature of 20°C and a relative humidity of 95% to obtain a comparison test piece. Other steps are the same as those in Embodiment 1 or 2.
