For microsurfacing, each mix ratio developed is a compatibility experiment, which is affected by multiple variables such as emulsified asphalt and aggregate type, aggregate gradation, water and emulsified asphalt amounts, and types of mineral fillers and additives. . Therefore, on-site simulation test analysis of laboratory samples under specific engineering conditions has become the key to evaluate the performance of micro-surface mixtures. Several commonly used tests are introduced as follows:

The fine surface is made of stone with a single particle size, which has high wear resistance and anti-slip properties. The construction of the fine surface adopts mechanized construction, which requires less manual labor and has the characteristics of fast construction speed, anti-skid and noise reduction.

The correct use of road construction machinery will directly affect the engineering quality of the entire highway, as well as the progress and efficiency of construction, etc. Effective maintenance and upkeep of road construction machinery is crucial to completing the entire production task. The main guarantee is that in the entire modern highway construction, the use of road construction machinery is very important.

What should we pay attention to when purchasing road construction machinery and equipment? In addition, what are the differences between the use of bearings and their use in engineering machinery and mechanical engineering manufacturing? These are related questions about road construction machinery. Global Road Construction Machinery will give specific answers below.

Safety standards for small asphalt mixers
1. Small asphalt mixer
It should be installed in a flat position, and square wood should be used to cushion the front and rear axles so that the tires are elevated to avoid movement when starting. 
2. Small asphalt mixers should be subject to secondary leakage protection. After the power is turned on before going to work, they must be carefully inspected. After an empty test run, they are found to be qualified before they can be used. During trial operation, it should be checked whether the mixing drum speed is appropriate. Under normal circumstances, the speed of the empty truck is slightly faster than that of the heavy truck (after loading) by 2 to 3 revolutions. If the difference is large, the ratio of the moving wheel and the transmission wheel should be adjusted. 

Asphalt Mixing Plants Weighing Control System Operation Key Points
1. Turn on the power
Before connecting the power to the asphalt mixing station, you should first close the DC24V air switch (the air switch does not need to be cut off after shutting down), and then turn the "POWER CONTROL" (start switch) to the "ON" state. At this time, observe and check whether the "POWER" (red indicator light) on the panel is lit. If it is lit, it indicates that the power of the control system has been connected. Wait for about 1 minute and check whether the touch screen displays normally. If it displays normally, it means that the power supply is normal. Otherwise, it should be inspected.
