Abstract
A reflective roadstud and manufacture of the same including steps of forming an upper and lower cover from mixture of Acrylonitrile-Butadene-Styrene, ABS and basalt fiber with a mixing ratio of 1:0.05˜0.5 by injection molding. The upper cover and the reflective sheet are combined by ultrasonic welding, and the lower cover is arranged to the upper cover as a finish. The finish is further coated by a nanotech inorganic heat dissipating coating (Sio2, Cao).

7-10. (canceled)
A reflective roadstud and manufacture of the same comprising:
- a upper cover of a flat trapezium body with arc front and rear edges;
- two slots for arranging reflective sheets being formed to two inclined reflective surfaces of the upper cover;
- the upper cover being formed integrated with both supporting structure of column or vaulted recess and geometry supporting structure of ultrasonic welding inside;
- two slots for scribing text being formed to a top surface of the upper cover to increase friction;
- a half hexagonal notch being formed to two lateral sides of the upper cover to increase friction;
- the slot being formed hexagonal, polygonal, circular, or oval-shaped;
- the upper cover being strong and having resistance against pressure, abrasion, impact, and climate through the supporting structure of column or vaulted recess or geometry supporting structure;
- a lower cover fixed to a lower side of the upper cover by ultrasonic welding;
- the lower cover being formed integrated with both supporting structure of column or vaulted recess and geometry supporting structure of ultrasonic welding inside;
- the supporting structure of column or vaulted recess or the geometry supporting structure of the lower cover being welded to the corresponding column supporting structure or geometry supporting structure of the upper cover by ultrasonic welding;
- the combined upper cover and lower cover being strong and having resistance against pressure, abrasion, impact, and climate;
- an enhanced groove being formed to a bottom surface of the lower cover so as to increase the traction;
- the enhanced groove being formed rectangular, polygonal, circular, or oval-shaped;
- two reflective sheets fixed to two slots of the upper cover;
- the reflective sheet having a geometric supporting structure formed by ultrasonic welding on a rear side thereof so that the reflective sheet has more resilience and resistance against impact and crush;
- the geometric supporting structure being formed rectangular, polygonal, circular, or oval-shaped.
