Cleanliness of emulsified asphalt is very important. Unclean emulsified asphalt will affect the quality of construction. Air into the emulsified asphalt, emulsified asphalt will be breaking. Cation emulsified asphalt in contact with the metal, will be breaking. If emulsified asphalt residue in the pump body, not cleaned, it will plug the pump. Line residual emulsion, not cleaned, it will cause pipe blockage. The better performance of emulsified asphalt, more thorough requiring of cleaning. Storage equipment must be cleaned thoroughly before the storage . Cleaning process as below steps:
a）Flushed with high-pressure water pipes； b）Cleaning with kerosene. Not allowed to use diesel or other cleaning solution, these fluids can not dissolve asphalt, incompatible with the emulsion, resulting emulsified asphalt emulsion breaking, inconvenient of cleaning; c）Finally, rinse with water pipes. Can not brush the inside bucket of emulsified asphalt; d）If the pump or line pitch has been blocked, it will be heated slowly, and then washed. You can not use the heating pipes, as it will emulsified asphalt emulsion break; e）Soaked with kerosene pump time up to an hour or more； f）After the blockage is cleared, rinsed with water pump again. Generally, emulsified asphalt is stable during transport . The most common problem is the air into emulsified asphalt , causing emulsified asphalt emulsion breaking, especially CRS emulsion, the air is able to activate a large precipitate particles generated emulsified asphalt, occurs the emulsion breaking phenomenon. For the main requirement is to ensure the correct use of the pump, and reasonable transportation method. In cold weather, use the pump to heat , a clean bucket, checking various conditions of loading. Put the emulsified asphalt in a clean buckets and closed for transportation. Emulsified asphalt is a chemical substance that can not be mixed with other types of emulsified asphalt products, but also can not be mixed with other chemicals. Iron rust, dirt, plants or other extraneous materials are not allowed to mix. For the cationic emulsion is particularly important because of its effect will happen with the debris generated demulsification phenomenon. Performance of small road roller Small roller first appeared in Britain in the 1980s, a company called Pi Feite machinery factory developed, produced first small hand roller. It is very simple structure, inconvenient operation. 1990s, China introduced imported the production technology, coupled with a completely developed tandem roller compactor and type of with cab. 1、Small roller easy to operate, since the entire machine itself is relatively lightweight, so the operation is very convenient, as long as the operator with relevant knowledge can control it, so called "fool advantages. 2、To get a small roller compaction density, the choice is tire roller. Tire roller will not damaging the soil original viscosity during rolling , good binding properties between the layers of soil, combined with the front wheels can swing it more uniform compaction, there will be no false compaction. Roller is a rolling plain for heavy machinery and equipment, it works primarily with its own gravity to those sandy, semi-clay soil of concrete or asphalt pavement plastic to strengthen the role of compaction. It is common for a higher level of traffic engineering requirements, such as highways, railways, bridges basis. Small roller’s volume is small, compact, easy to transport,work strength , high efficiency. And supporting use with the large rollers. With the development of urban construction, small roller used more widely, which also contributed to the development of small roller manufacturers. Two-chamber of small roller hydraulic cylinder communicates with the oil tubing. Small roller hydraulic cylinder , to the two chambers simultaneously through the high-pressure oil, at the same time as the two chambers pass into the high-pressure oil, but vary the effective area of the two chambers, so that the force generated ranging rod chamber there are more than traction rod chamber, push the piston moves to the right, right-drained fluid chamber and into the left chamber of the cylinder, thus increasing the flow of the left chamber, accelerated to the right movement.
