Abstract

The invention relates to a blending type room-temperature asphalt liquefier, which comprises the following components by weight percent: 5-12 percent of liquid modifier, 3-9 percent of cation surfactant, 2-5 percent of stabilizing agent and 20-30 percent of water. A preparation method of the blending type room-temperature asphalt liquefier comprises the following steps of: mixing water and the cation surfactant according to the proportion, sufficiently mixing by an emulsion machine to form soap lye, and heating to 55-70 DEG C, uniformly mixing the liquid modifier and the stabilizing agent according to the proportion to form a homogeneous body, and heating to 55-70 DEG C; quickly mixing the soap lye and the homogeneous body in a melt-mixing device, grinding to form even and stable jelly, and preserving in a sealing mode or an intermittence stirring mode. The liquefier can be simply mixed with asphalt to produce cold blending asphalt suitable for preparing cold blending mixing materials. The invention is used for paving an asphalt and concrete road surface.

Description

technical field [0001] The invention relates to the field of additives used in asphalt paving, in particular to a mixing type room temperature asphalt liquefaction agent. Background technique [0002] A large number of asphalt is used as the pavement cementitious material for highway pavement. As a cementitious material, asphalt must first be heated and melted, and the high-grade pavement must be modified and processed. At the same time, the aggregate must be heated to 200°C, and then mixed. Under heat preservation, it will be transported, paved, and rolled to form asphalt pavement. All processes consume a lot of fuel and generate greenhouse gases. At the same time, the project construction is seriously affected by the climate, the process coordination requirements are strict, the material utilization rate is low, and the waste is serious. Seriously pollute the environment and the health of construction workers. [0003] Domestic patent No. 200910027834.0 discloses a liq...
