美国标准 AASHTO M 249白色和黄色反射热塑性条纹材料(固体形式)

Test or certification item 测试或认证名称: White and Yellow Reflective Thermoplastic Striping Material (Solid Form)
白色和黄色反射热塑性条纹材料(固体形式)

Test or certification info 测试和认证相关内容:
AASHTO M 249 涵盖了一种反光热塑性路面条带材料，该材料通过机械方式以熔融状态涂覆在路面上，并以买方规定的速度在表面涂覆玻璃珠。当冷却至正常路面温度时，它会产生一条具有规定厚度和宽度的粘性反光条纹，能够抵抗交通变形。
AASHTO M 249 covers a reflectorized thermoplastic pavement striping material that is applied to the road surface in a molten state by mechanical means with surface application of glass beads at a rate specified by the purchaser. Upon cooling to normal pavement temperature, it produces an adherent reflectorized stripe of specified thickness and width capable of resisting deformation by traffic.
