Abstract
The invention is a ground marker that is durable and yet can be manufactured with ease and without great expense. The ground marker has a shell portion bonded to a support structure. A lip formed around the periphery of the support structure against which the shell rests maintains the shell in a secure position. The support structure has support posts that serve to buttress the shell which bears the weight of vehicles traveling thereon. Filler material disposed between the shell and support structure serves to provide further support. A coating of protectant, preferably ceramic, provides reflectivity and protection against the elements.
