LEIVA VILLACORTA, Fabricio; CAMACHO GARITA, Edgar  and  AGUIAR MOYA, José Pablo. Simulation of weather conditions on full scale accelerated pavement testing. Infraestructura Vial [online]. 2016, vol.18, n.32, pp.20-29. ISSN 2215-3705.

Full scale accelerated pavement testing provides much more information about the actual behavior of pavement structures subject to specific mechanical stresses. While this is the main factor causing damage to pavements, climate also affects performance and has not been extensively studied in full scale tests, much less its effect on an accelerated basis. This article describes part of the implementation of a system to include an accelerated form of weather variables in the laboratory full-scale pavement facility called PAVELAB of LanammeUCR. The system has unique capabilities including simulation of high and low temperatures, wind, rain and solar radiation. Some results of the first tests with the new system are shown in this paper and some of the possible climatic varieties of interest to characterize the climate of Costa Rica in the tests performed in the PAVELAB are also shown.

Keywords : Accelerated testing; weather conditions; aging; Costa Rica.
