Water, being a fluid capable of absorbing and retaining radiation, is a factor that affects a wide variety of physical processes. The influence of water on the surface temperature of pavements is related to their evolution in various climatic conditions. The research seeks to know the impact of rainwater on the temperature of the surface layer of pavements in a set period of time. For this, the surface temperatures of two different types of pavement were evaluated: one that contains water and another that does not contain water. The results show that when the pavement is wet, the surface temperature is lower compared to the opposite case. This research contributes to the generation of useful information for decision-making in local governance and the adoption of mitigation or adaptation measures in the face of the impacts of climate change.
