INTRODUCTION OF THE LABORATORY
The main profil of the Road Construction Laboratory is the examination of the conformity of materials to be incorporated during road construction. Our laboratory has a floor area of 200 m2, we have a number of equipment with which we can perform mechanical tests of asphalts, bitumen tests, visibility tests and nondestructive georadar diagnostic tests. The staff of our laboratory has significant experience in the field of research development, expert and consulting, construction and technical inspection related to road construction. Our goal is to expand our range of tests across the current cross-section to the widest possible spectrum.
