Impact deflectometry in the structural evaluation, Central Highway km 12 + 250 - km 26 + 500, Lima 2020

This research analyzes the incidence and efficiency of impact deflectometry to evaluate design road reinforcements a section central highway. For this study, non-destructive methodology has been used, based on collection, processing, interpretation deflections measured surface with deflectometer equipment; these reflect response structural package under given load, its measurement is simple, fast non-destructive, that is, we do not alter package, above all, cause vehicular congestion as it would be conventional methodology. The are analyzed using back-calculation technique, which allows us know total Structural Number in function characteristics rigid pavement, obtaining number Sn 6.2 5.6 for right left roadway, respectively. presents results current condition study. It proposes technique calculating an asphalt reinforcement concrete from back-calculation.
