Development of low cost and innovative smart materials for highways and civil engineering structures D. G. Goulias Department of Civil and Environmental Engineering, University of Maryland, USA Abstract With the increasing cost of infrastructure monitoring and maintenance and the limited funding for these activities the engineering community is looking towards the development of smart materials. Today there are several examples of innovative smart materials requiring however a) increased high- tech knowledge for their installation monitoring and interpretation of data, and b) significant expense for their installation in large scale projects, such as highways and bridges. This paper presents the result of a project undertaken for investigating the development of simple and low cost sensor for concrete and asphalt mixtures. Several configurations of metallic grids were imbedded into concrete and asphalt beams that were exposed to different stress and
