Abstract

A sensorized elastomeric expansion joint (1), comprising: at least one elastomeric body (2), elongated along its longitudinal axis (14), having an upper face (21) that comprises two upper grooves (3) and a lower face (22), that comprises a lower groove (4) that extends parallel to the longitudinal axis (14); two L-shape parts (5), embedded in the elastomeric body (2), made of two plates which form a 90° angle, extending along the longitudinal axis (14); a plate (6), embedded in the elastomeric body (2) between the upper grooves (3) and disposed in a plane parallel to the upper and lower faces (21, 22) and extending along the longitudinal axis (14); and one or more buckypaper strip sensors (8), completely embedded in the elastomeric body (2) in a plane parallel to the upper and lower faces (21, 22).
