Artificial road roughness IDN 500 is made of high quality impact resistant rubber. On the outer surface of the elements there are spherical protrusions for excellent traction with car tires. The lower part of the product has a tread that provides proper drainage. The mounting holes are reinforced with metal discs 50 x 3 mm, which increases the clamping capacity of the product and eliminates its pulling out.

A 2-component composition is introduced into the hole drilled in the asphalt, with a hardening time of 10 min to 1 hour. IDN holder is any metal pin, bolt or screw inserted into the hole with the adhesive.
Advantages: Reliable enough fastening with 100% filling of all cavities in the drilled hole.
Disadvantages: Installation requiring good qualification of installers (a rarity for many structures such as GOSSMEP ..). Long hardening time. High price.
1. Wedge anchor.
The most common type of mount. There are many manufacturers. When completing our own products, we have been using Fischer and Sormat for 6 years. In accordance with GOST asphalt pavement, the wedge anchors of these manufacturers are good. The cost of analogues from China and Taiwan is lower by 30-40%, but we can not say anything about their quality and reliability. Recommended size: diameter 10-12mm, length 90-120mm, head type - bolt-on.
Advantages: Simplicity and speed of installation.
Disadvantages: In loose asphalt insufficient degree of wedging, because their main purpose is concrete.
2. Screw and dowel.
Also a commonly used type of mount. The expansion bolt shield can be used both metal (for aerated concrete), and polyethylene. With high-quality asphalt, you can safely use them, significantly saving on the cost of fasteners.
Advantages: Simplicity and speed of installation, price, the possibility of subsequent tightening.
Disadvantages: Insufficient degree of wedging.
