Pavement element

Abstract

A pavement element is revealed. The pavement element includes a thermally conductive covering element and a solar collector frame. The thermally conductive covering element is a foamed metal disposed with a plurality of through holes for providing slip resistance and drainage function. Moreover, the solar collector frame collects heat and then the heat is transferred to the thermally conductive covering element so as to cause high temperature for killing insect larvae or eggs attached to the thermally conductive covering element.
