Embodiment 1
[0068] Take 16Kg of clean water, add 1.8Kg of slow-cracking and fast-setting cationic emulsifier (RC-SMRHJ804 Jiangyin Rongcheng Road and Bridge Company) in the water, add 20Kg of composite modified polymer SBR latex and 10Kg of natural latex (based on polymer weight) , 2.5Kg mixed sodium naphthalenesulfonic acid formaldehyde salt as dispersant, 1.5Kg polyethylene glycol fatty acid, after stirring evenly, continue to stir evenly and maintain the temperature when the temperature reaches 65°C. Take 60Kg of Sinopec aromatic hydrocarbon base AH-704# heavy traffic asphalt, 5kg of carbonate cement and heat it to 165°C, stir together evenly and add it to the colloid mill for grinding at a speed of 5000 rpm. After 5 minutes of processing, the cold state to be prepared will be obtained. High strength bitumen. The test results show (see Table 2-4) that the various indicators are ideal, the residual amount on the sieve is small, the storage stability is good, the softness is high, the vi...
Embodiment 2
[0070] In this example, the cold high polymer asphalt produced by Jiangyin Rongcheng Road and Bridge Company is used. The stone material is basalt, cold mix expansion agent, No. 500 cement, and pure water are cold mixed to form cold mix high polymer modified asphalt concrete. The formula and performance are listed in Table 5 below:
