<p>This invention relates to an improved roadstud and a method to pave the same into the road. The improved roadstud comprises a base body (2) consisting of a head member (21) provided at the upper side with a slot (211) and a shaft (22) with a sharp portion (223) at its lower end extending downwardly from the underside of said head member (21). Said shaft (22) is furnished with a plurality of triangular fins (221) formed integrally with said head member (21) to prevent the roadstud from being twisted when paved into the road, and truncated conical members 222. An arcuate reflective means (1) provided at the underside with a reflective hole (11) is received in the slot (211) of said base body (2). The head portion of a pneumatic hammer can be placed on the circumference of said head member and pave said roadstud into the road. <IMAGE></p> |
