Motorway Studs reflective sheet is also called Motorway Studs sheet. The damage effect of the Motorway Studs sheet is mostly due to the partial or overall rupture of the reflective sheet due to the foreign matter (such as small stones, etc.) entrained in the tire when the vehicle runs over the Motorway Studs. Motorway Studs reflectors are mostly prismatic reflectors made on the principle of total reflection. This type of reflector is characterized by high retroreflective efficiency. If the sealing structure of the reflector is damaged, once water and dust penetrate into it, its reflective efficiency will drop sharply. , Causing the reflector to not reflect light.

The effect of avoiding the damage of the reflective sheet can be achieved by improving the material strength of the Motorway Studs nail sheet and improving the structure of the Motorway Studs nail sheet. At present, due to the limitations of material technology, an effective solution to greatly increase the strength of Motorway Studs cannot be found. The improvement of the structure of the Motorway Studs nail sheet is to divide the original overall Motorway Studs sheet structure into a structure of several reflective units isolated from each other, so that after the Motorway Studs sheet is partially damaged, only the local reflective effect is affected, while other reflective units It can still work normally, so that the overall brightness of the Motorway Studs will not drop much, thereby reducing the failure of the Motorway Studs sheet caused by local damage.

Reflective Studs sheet and the Reflective Studs body separation failure is mostly caused by the Reflective Studs sheet and the Reflective Studs body is not firmly bonded, after repeated rolling by the vehicle, the joint part cracked under the action of alternating stress.

Improving the firmness between the Reflective Studs sheet and the Reflective Studs body can effectively avoid such failures.

There are many reasons for the failure caused by the attenuation of the reflective brightness of the reflector. There are two main reasons, namely, the poor weather resistance of the reflector material and the abrasion of the outer surface of the reflector.

If the weather resistance of the material is not good, the shuttle mirror will be deformed after a period of use, and the angle formed by the four faces of the tetrahedron will change, which will cause the reflection efficiency to decrease or even no reflection. Improving the weather resistance of the Reflective Studs sheet material can effectively avoid the resulting failure.

The decrease in reflectance brightness caused by the wear of the reflector surface is due to the friction between the vehicle tire and the Reflective Studs reflector, which makes the originally smooth reflector surface rough, thereby reducing the reflection efficiency of the reflector. Increasing the abrasion resistance of the reflector surface is an effective way to solve this type of failure mode.
