粘层温度常温沥青
英文回答：
The term "stickiness temperature" refers to the temperature at which a bituminous material, such as asphalt, becomes sticky or adhesive. It is an important property to consider in the construction and maintenance of roads and pavements.
The stickiness temperature of asphalt is influenced by various factors, including the type and grade of the
asphalt binder, the aggregate used in the mixture, and the environmental conditions. Generally, the stickiness temperature of a typical asphalt binder falls within the range of 100-150 degrees Fahrenheit (38-65 degrees Celsius).
At temperatures below the stickiness temperature, the asphalt binder is solid and not adhesive. However, as the temperature rises and reaches the stickiness temperature,
the binder starts to soften and become sticky. This
stickiness is crucial for the proper bonding of asphalt layers during construction and the adhesion of asphalt to aggregate particles.
It is important to note that the stickiness temperature of asphalt can vary depending on the specific application and requirements. For example, in colder climates, the stickiness temperature may need to be lower to ensure proper workability and compaction of the asphalt mixture. Conversely, in hotter climates, a higher stickiness temperature may be desired to prevent rutting or bleeding of the asphalt pavement.

粘层温度是指沥青等沥青材料变得粘性或具有粘附性的温度。

这是在道路和铺装的建设和维护中需要考虑的重要性能。

沥青的粘层温度受多种因素影响，包括沥青黏结剂的类型和等级、混合料中使用的骨料以及环境条件。

一般来说，典型沥青黏结剂的粘层温度在100-150华氏度（38-65摄氏度）范围内。

在粘层温度以下的温度下，沥青黏结剂是固体且不具有粘附性。

然而，随着温度的升高并达到粘层温度，黏结剂开始软化并变得粘性。

这种粘性对于在施工过程中沥青层之间的正确粘结和沥青与骨
料颗粒的粘附非常重要。

需要注意的是，沥青的粘层温度可以根据具体应用和要求而有
所不同。

例如，在寒冷的气候中，为了确保沥青混合料的适当可塑
性和压实性，可能需要更低的粘层温度。

相反，在炎热的气候中，
可能需要更高的粘层温度以防止沥青路面产生车辙或渗漏。
