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:

Abstract

The invention relates to a cold mixing high polymer modified bitumen concrete and a method for producing the same. The concrete comprises 5.0 to 15 weight portions of cold state high polymer bitumen, 55 to 70 weight portions of stone, 1.0 to 5 portions of stone dust, 1.0 to 4 portions of cement, 4.0 to 10 portions of cold mixing swelling agent and 5.0 to 27 portions of pure water which are prepared into the cold mixing high polymer modified bitumen concrete through normal cold mixing. The concrete has the advantages of simple production, novel and unique formulation, excellent performance and energy conservation, is the cold mixing high polymer modified bitumen concrete for a rapid, economic, energy-saving and environment-friendly high grade highway with excellent performance, and can be widely applied to the bitumen concrete pavements paved for various grades of highways.

Description

technical field [0001] The invention relates to the field of road paving asphalt concrete, in particular to a cold-mixed high polymer modified asphalt concrete with excellent high and low temperature performance, water stability, cohesive force and durability and a manufacturing method thereof. technical background [0002] my country has used hot-mix asphalt concrete for more than 50 years. People turn solid asphalt at room temperature into liquid by heating, and then mix it with various mineral materials to form hot-mix asphalt concrete, which is paved on the road and repeatedly rolled. Press, this is the asphalt road. Later, people added high-molecular polymers to the asphalt, and used special equipment to modify the asphalt to produce modified asphalt concrete, which is used on high-grade roads. This is modified asphalt concrete. There are many disadvantages in the construction of hot mix asphalt or hot mix modified asphalt, which not only requires a lot of heat energy,...
