What is Non-Contact Resonance in Asphalt Concrete about?
This conference paper discusses the non-contact excitation of fundamental resonance frequencies in asphalt concrete specimens using a speaker and impact hammer. The study finds that while both methods yield similar resonance frequencies for undamaged asphalt concrete, the concrete specimen shows a nonlinear response under strain. The results suggest that non-contact excitation could be a promising method for measuring resonance frequencies without disturbing temperature conditions.
