Common problems of road stud installation

With the wide application of road stud, the quality problem and service life of road stud have got more attention. While in the process of practical application, damage and shortening of the service life of road stud appear frequently due to installation problems. 

Road Stud Road stud


1. Uneven installation position of road stud. As a direct result, the stress of road stud would be non-uniform, which is concentrated almost on the convex and concave part so that the road stud is easy to break if there are any big tonnage vehicles.  

2. The installation position of road stud is not clean. The fastness of road stud depends on the joint connection of road stud, glue and ground. If the installation position is not clean, the dust would adsorb most of the boning force of glue that the bond of road stud is not firm, which is easy to fall off due to external shocks.   

3. The dosage of glue is not enough or too much. Insufficient glue would reduce the fastness and service life of road stud; while if the dosage of glue is overmuch, excess glue will seeping from all around of road stud, which is easy to wipe to the reflectors of road stud, affecting its brightness.

4. Lower environment temperature when allocating epoxy resin glue. Epoxy resin glue is a two-component glue that the glue and curing agent must be mixed according to certain proportion ratio and stir evenly to work efficiently. But the epoxy resin glue would congeal in cold weather in winter so that it's not easy to stir evenly. Thus, the glue must be heated before using.

5. The holding method of road stud is not scientific. The road stud must be held on the both sides of no reflectors in order to avoid the glue on the reflectors that affects the brightness of reflectors.   

6. The mounting hole of road stud is shallow and thin. This is mainly for casting aluminum road stud with foot screw. Cast aluminum road stud with foot screw has better shock resistance, compressive performance and longer service life due to part of road stud embed into the ground. But in the process of installation, if the hole is too shallow or thin, then the bottom of road stud can't contact with the ground fully, which would affect the bonding effect.   

7. Glue curing time is not enough after installation. After installation of road stud, there should be a period of time for curing the glue to make the road stud and ground bonded closely, four hours are recommended. But in the actual process, a lot of people would remove the isolation facilities in less than two hours after installation. As a result, the road stud would deform or even fall off under the vehicle dashing and rolling.

8. Being installed on the marked lines on the ground. The marked lines are painted with the resin material, and it is painted on the ground, and it has limited connected force with the ground. If the road studs are installed directly on the marked line, the impact force on the road stud will be shifted to the marked lines totally, which makes the road stud fall apart with the marked lines, and sometimes the marked lines will be destroyed with the falling apart of the road stud.
 
9. The adhesive is not smeared evenly. In the installation, the used amount of the road stud should be moderately, and it should be smeared evenly, which makes all the parts of the road stud can get even load and avoid the breaking into pieces of uneven load.
