国家为什么大力发展再生工艺？

Why does the country vigorously develop recycling technology?

　　第一个，资源的再次利用，符合国家及世界大的政策方针，势在必行。

The first is that the reuse of resources is in line with national and global policy guidelines, and is imperative.

　　给大家看一组数据：

Let me show you a set of data:

　　截至2030年，预计我国公路网总规模将达到580万公里，

By 2030, it is expected that the total scale of China's highway network will reach 5.8 million kilometers,

　　按照沥青路面的设计寿命（15~20 年），

According to the design life of asphalt pavement (15-20 years),

　　每年约有12%的沥青路面需要翻修，

Approximately 12% of asphalt pavements require renovation every year,

　　旧沥青混合料废弃量将达到290万吨之多，

The amount of discarded old asphalt mixture will reach up to 2.9 million tons,

　　如能加 以利用，每年可节省材料费用3亿元以上，

If utilized, it can save material costs of over 300 million yuan annually,

　　而且这个数字还将以每年15%的速度增长。

And this number will also grow at a rate of 15% per year.

　　所以我们没有道理不去使用再生工艺。

So we have no reason not to use recycling technology.

　　第二个，尽管中国推广再生工艺的时间不算长，但国内外大量工程案例和研究结论表明，沥青路面再生技术成熟可靠，只要科学设计、精心施工，工程质量可以保证。在国外再生料的利用率是非常之高的，比利时和德国等国家已经实现了100%的利用率，所以我们国家从2008年开始逐步推广再生工艺，近两年推广速度更加迅速。

Secondly, although China has not been promoting recycling technology for a long time, a large number of engineering cases and research conclusions at home and abroad indicate that asphalt pavement recycling technology is mature and reliable. As long as scientific design and careful construction are carried out, the engineering quality can be guaranteed. The utilization rate of recycled materials is very high abroad, and countries such as Belgium and Germany have achieved a 100% utilization rate. Therefore, our country has gradually promoted the recycling process since 2008, and the promotion speed has been faster in the past two years.

　　ASTEC公司将再生料铺设后，负载卡车在上面按照设计标准和年限连续运行，在时间节点取样进行测试，最后实测的数据结果是再生料铺筑的路面不比新料差，而且在抗车辙等方面性能优于新料。

After laying the recycled material, ASTEC company continuously operated the load truck on it according to the design standards and service life. Samples were taken at time nodes for testing. The final measured data showed that the road surface paved with recycled material was not inferior to the new material, and its performance in resistance to rutting was better than that of the new material.

　　所以再生料铺设后的路面性能上是可靠的。

So the performance of the road surface after the laying of recycled materials is reliable.

　　再生从大的方面可以分为两类，也就是大家时常听到的热再生和冷再生，大家可以简单理解成一个需要对旧沥青料加热处理，一个不需要对旧沥青料加热处理，同时两种再生方式又分为就地再生和厂拌再生。

Regeneration can be divided into two categories from a large perspective, namely hot regeneration and cold regeneration, which are commonly heard. They can be simply understood as one that requires heating treatment of old asphalt materials, and the other that does not require heating treatment of old asphalt materials. At the same time, the two regeneration methods are further divided into on-site regeneration and plant mix regeneration.
