摘要：
The proposed study focuses on the mechanical behavior of recycled asphalt mixtures using a full-field measurement technique, namely the grid method. For this purpose, cylindrical samples made of hot mix asphalt mixtures containing 0%, 20%, 40%, and 100% of RAP were prepared. Aggregates of different colors were selected in order to distinguish RAP and virgin aggregates. Compression tests were carried out on cylindrical samples. Displacement and strain fields were measured during these tests. The obtained results highlight the difference in behairior between samples both at the micro- and the macro-scales.
