Usually we refer to the machinery and equipment related to road construction as road construction machinery. In other words, road construction machinery is a relatively broad concept that includes many equipment. So, let’s talk about the maintenance and management of road construction machinery.

Preparations before starting up

1. Check
① Understand the impact of weather conditions (such as wind, rain, snow and temperature changes) on the production day;
② Check the liquid levels of diesel tanks, heavy oil tanks, and asphalt tanks every morning. When the tanks contain 1/4 of the oil, they should be replenished in time;
③ Check whether the temperature of the asphalt reaches the production temperature. If it does not reach the production temperature, continue to heat it before starting the machine;
④ Check the aggregate preparation situation according to the ratio of cold aggregate, and the insufficient parts must be prepared for reproduction;
⑤ Check whether the on-duty personnel and auxiliary equipment are complete, such as whether the loader is in place, whether the vehicles are in place, and whether the operators at each position are in place;

How to be a qualified asphalt mixing plant operator? First of all, the operator should be proficient in the structure and working principles of each part of the mixing station. On this basis, strictly control all production details, especially the metering system, because the quality of the metering work will directly affect the quality of the asphalt mixture. Technical indicators.
Regarding the stone measurement system, it should be noted that:

Modified asphalt (composition: asphaltene and resin) The equipment is divided into two types: open system and closed system according to the different states of emulsified asphalt and emulsifier aqueous solution when they enter the emulsifier: the characteristic of the open system is to use valves to control the flow , emulsified asphalt and emulsifier flow into the feed funnel of the emulsifier by their own weight.

In use, the emulsified asphalt heating tank is intelligent and efficient, has low investment, low power consumption, low cost, high thermal efficiency, and fast heating, and can reach the temperature required for construction in a short time, which also indirectly saves users a lot of time. It requires less manpower and material resources, and the emulsified asphalt heating tank has fewer accessories, is simple to operate, and is easy to move. It can be operated by one person with a single set of heaters.

With the continuous improvement and development of asphalt gravel sealing technology, a series of new asphalt gravel sealing technologies have been born in road maintenance, and rubber asphalt fiber synchronous gravel sealing technology is one of them. In order to allow everyone to better understand and use it, let's follow the editor of Sinoroader Group, a manufacturer of fiber synchronous gravel sealing, to learn more about its characteristics.
