According to the difference between the original road structure and the new design scheme, in-situ cold regeneration can combine a variety of construction schemes! In fact, the working principles of various construction schemes are the same. The difference is the different materials and methods. In situ cold recycling of asphalt pavement with cement as additive is a common scheme.

在利用水泥进行就地冷再生时，外加料主要是水泥，水泥的通常用量按重量计在2%-5%之间比较合适。如果水泥的用量过多，容易使再生层变脆。同时还要加入适量的水。

When using cement for in-situ cold regeneration, the additive is mainly cement, and the usual dosage of cement is between 2% - 5% by weight. If the amount of cement is too much, it is easy to make the regeneration layer brittle. At the same time, add an appropriate amount of water.

水泥的加入方法有两种，一种是利用人工或专用机械将水泥预先撒布在需要再生的路面上。这时水的加入方法，是通过冷再生机上所配备的微机控制系统从跟班作业的运水车内输送到冷再生机的拌和仓中。

There are two methods of adding cement. One is to use manual or special machinery to pre distribute the cement on the pavement that needs to be recycled. At this time, the water is added through the microcomputer control system equipped on the cold regenerator from the water truck for attendant operation to the mixing bin of the cold regenerator.

另一种方法是采用水泥稀浆搅拌输送车，将需要添加的水泥和水搅拌成水泥稀浆，再通过冷再生机上的控制系统将其输送到冷再生机的拌和仓中。

Another method is to use the cement slurry mixing truck to mix the cement and water to be added into cement slurry, and then transport it to the mixing bin of the cold regenerator through the control system on the cold regenerator.

这种方法的优点就是在控制用量方面非常方便。因为在施工中冷再生机要分几个工作行程才能完成一个作业段内整幅路面的铣刨，而再生层的碾压要等到整个作业段全部施工工序完成之后才能进行，这就形成先铣刨的路面和后铣刨的路面到碾压时所等待的时间间隔相差很多。

The advantage of this method is that it is very convenient in controlling the dosage. During the construction, the cold recycling machine needs to divide into several working strokes to complete the milling of the whole pavement in an operation section, and the rolling of the recycling layer can only be carried out after all the construction processes of the whole operation section are completed, resulting in a great difference in the waiting time interval between the first milling pavement and the later milling pavement.
