Regarding detection issues:
A. China's
Road Studs detection methods are roughly divided into three categories:
1. For sample testing, that is, only responsible for Road Studs samples;
2. For batch testing, that is, only responsible for the quality of this batch of
Road Studs;
3. Inspect the factory to know whether there is machinery and equipment, whether there is a perfect system, and issue a
Road Studs mass production license.
B. There are two types of detection methods in the United States:
1. For sample testing, this is similar to that in China;
2. Outdoor
Road Studs installation experiment observation (Field Testing), which is different from China and is also a key point to be introduced in this article.
a. The first is the selection of the experimental standard road section, which has the following conditions:
①, the road is free to pass;
②. During the inspection period, the
Road Studs pavement will not carry out any maintenance construction.
③. The traffic flow is 35,000 times, and then install the specified number of Road Studs on it.
b. Outdoor observation
Road Studs have been installed on the road for two years and observed once every six months. The
Road Studs shell, the reflector surface, and the interior of the reflector are observed, and the observation results are divided into five grades:
5. excellent, complete, like new;
4. Very good, with small scratches;
3. Moderate, with obvious flaws, but still functional;
2. bad, serious damage, weak effect;
1. Very poor and totally useless.
Then check its luminous intensity.
c. Report
1. An observation report is issued once a year, a final report is issued every two years, and then the report is sent to the government. The report includes the following contents:
①.
Road Studs Photos
②. Average traffic flow at the experimental site
③. Large truck ratio
④. rain data
⑤. Data at high and low temperature
⑥. Laboratory Road Studs Data
⑦. Comprehensive description of the laboratory
⑧. Binder type
⑨. Outdoor observation data
The above briefly compares the similarities and differences between the detection methods of China and the United States. Which method is more reasonable and scientific?
Let’s start with an analogy. If a road is compared to a person,
Road Studs is more like a pill. He guarantees the health and safety of the road. Before a drug enters the market, it is not only necessary to carry out
Road Studs in the laboratory. Trials, and more importantly, must be used and observed in the clinic for a long time before they can enter the market.
Road Studs in the United States install experiments, just like clinical trials of drugs, and what our country lacks is the most important link.
Regarding the issuance of mass production
Road Studs licenses, I think this is still a way of thinking in the era of planned economy, thinking that enterprises should be small and complete, and production, manufacturing, and sales should be completed in their own enterprises, not relying on Social division of labor. The characteristics of the market economy are the refinement and deepening of the social division of labor, so that various resources can flow and be used to a greater extent. Those who do manufacturing focus on manufacturing, those who do professional design focus on design, those who do testing focus on testing, Road The birth of Studs is a product of social division of labor, not a single
Road Studs product. Let me tell you the simplest example. There are many excellent
Road Studs brands in the world, all of which are made in China. How does the US government inspect production equipment and bases? , the functional departments of the US government only need to monitor the use of
Road Studs products on the road every year. This method is the way of the nose.
