Embodiment 1
[0022] Determination of optimal cement content:
[0023] 1) Determination of waste aggregate grading
[0024] In order to accurately determine the collection and distribution of stone materials, the pavement waste materials are extracted and screened. The AC-13 used in the original pavement was assembled, and the screening results are shown in Table 1.
[0025] Table 1 Screening results of asphalt pavement waste materials
[0026]
[0027] Weigh 10kg of the above-mentioned waste materials and number them as A, B, C, D, respectively add cement 50g, 100g, 150g, 200g to ABCD, and then add 800g mineral powder to ABCD four kinds of stones, so that ABCD stones can meet According to the requirements of AC-13, add 50g of super absorbent polyacrylate and 20g of chopped carbon fiber waste (about 3mm long) to ABCD, and mix the stone in ABCD with cement, water absorbent resin and carbon fiber waste in a stirring pot. Stir well. Add tap water to the above-mentioned stones until the ...
Embodiment 2
[0033] Investigation of different types of emulsified asphalt:
[0034] The test method is the same as in Example 1, the amount of cement is 1% (100g), the amount of emulsified asphalt is the same, the type is cationic emulsified asphalt (test number E), and the solid content is 65%. Test its anti-rutting performance and trabecular bending test. The experimental results are shown in Table 2.
Embodiment 3
[0036] Investigation on the amount of different water-based epoxy resins:
[0037] The test method is the same as in Example 1, the amount of cement is 1% (100g), the emulsified asphalt is nonionic emulsified asphalt, and the mass ratio of emulsified asphalt and water-based epoxy resin is 2:1 (test number is F) and 3:1 ( Test number is G). Test its anti-rutting performance and trabecular bending test. The experimental results are shown in Table 2.
