Roller-compacted concrete (RCC) pavements have been the subject of studies focused on
their increasing deterioration over time due to the influence of vehicular loading and ambient factors
in humidity and temperature conditions ranging from medium to low (40% relative humidity and
25 ºC temperature). Therefore, it is necessary to understand how they behave under various relative
humidity and temperature conditions since these parameters vary in each geographic region. In this
context, this research focused on analyzing the effect of drying shrinkage on RCC pavements under
the influence of vehicular loading using a computational model calibrated with data obtained under
typical ambient conditions. For this purpose, laboratory experiments were performed, numerical
modeling was used, and the results for RCC pavements were validated using statistical analysis. The
results revealed validated models providing moisture content and drying shrinkage curves. These
results also underline the importance of considering ambient effects when calculating pavement
stresses as a response variable in structural designs. In particular, these effects are highlighted as they
can generate changes in pavement stresses of up to 10%, emphasizing the relevance of the models
proposed in this study as they consider this phenomenon when predicting the performance and
durability of RCC pavements.
