Emulsified bitumen for vertical connected plate type unballasted track cement emulsified bitumen mortar

Номер: CN0101475747A
Принадлежит:

The invention relates to emulsified asphalt for longitudinal connecting plate type ballastless track cement emulsified asphalt mortar. The emulsified asphalt comprises the following components in percentage by weight: 60 to 65 percent of asphalt, 0.2 to 5 percent of anionic emulsifier, 0.02 to 3 percent of stabilizing agent, 0 to 4 percent of assistant, and the balance being water; and the wax content of the asphalt is less than or equal to 2.2 percent. The emulsified asphalt for the longitudinal connecting plate type ballastless track cement emulsified asphalt mortar has good emulsifying effect, is not only suitable for storage and usage under normal temperature environment, but also suitable for storage and usage under the environment of lower temperature or higher temperature, and has the advantages of good storage stability, strong temperature adaptability and the like; and the cement emulsified asphalt mortar prepared by the emulsified asphalt has the advantages of long working time ...

Dry material for vertical connected plate type unballasted track cement emulsified bitumen mortar

Номер: CN0101475350B
Принадлежит:

The invention relates to a dry material used for a cement emulsified bitumen mortar of vertical connecting plate type ballastless rails, which comprises the following components in portion by weight: 100 portions of gelled material, 138 to 195 portions of sand, 0.05 to 0.5 portion of fiber, 0.003 to 0.01 portion of aluminum powder, 0 to 0.1 portion of polymer, and 0 to 10 portions of stone dust. By adding fiber, particularly hydrophilic fiber to dry materials, the toughness, the shock resistance and the fatigue resistance of the mortar prepared from the dry materials can be improved, the bleeding phenomenon of the mortar can be avoided and the lasting quality of the mortar can be improved; simultaneously, by selecting different gelled materials, particularly the combinations of between the different gelled materials, the problem that the prior dry material and the mortar prepared from the dry materials are difficult to satisfy the requirements on various construction environments and use ...

Special interface agent for CRTS concrete base plate of ballastless track and preparation method thereof

Номер: CN0101914328A
Принадлежит:

The invention relates to a special interface agent for a CRTS concrete base plate of a ballastless track, which comprises the following components in parts by weight: 20-40 parts of a high molecular polymer, 0-5 parts of a film-forming adjuvant, 0.5-1.0 part of a mildewproof agent, 0.1-0.3 part of a thickening agent, 0-0.5 part of a pH regulator, 40-60 parts of water and 0.3-1 part of a defoaming agent. The preparation method of the special interface agent comprises the following steps: adding the components in parts by weight to a stirring vessel at a speed of 400-500r/min, stirring for 5-10 minutes, adding 0.3-1 part of the defoaming agent, and evenly stirring with stirring speed of 150-250r/min to obtain a product. The special interface agent of the invention can seal capillary pores and slits of the concrete base plate, lower absorbability, prevent moisture in cement-emulsified asphalt mortar from being too quickly infiltrated into a bottom layer, avoid occurrence of penetration air ...
