[0022] The present invention will be further specifically described below in conjunction with the examples.
[0023] During the hot-in-place regeneration of asphalt pavement, choose a road surface after milling and before paving, and spread ordinary Portland cement evenly on the road after milling. The recommended spreading area is 20cm×20cm~30cm×30cm , the spreading center point is 40cm~60cm away from the milling edge, the amount of cement spreading is about 500g~800g, mark it after spreading; after the cement spreading place is rolled and paved, and the road surface temperature drops to 50°C, use a road core drilling rig Drill a hole at the central point of cement spreading to take the core, and separate the regenerated layer of the core sample from the layer below; measure the diameter d of the core sample with a vernier caliper, accurate to 0.1mm; place the core sample in a hydrostatic balance, and weigh Its weight in water m 1 , accurate to 0.1g, after taking out the cor...
