An important factor affecting the residents’ quality of life is the condition of the city’s roads. One of the community’s essential necessities is to paving and maintaining urban roads since this allows for the safe, timely, and comfortable movement of people and commodities. On this basis, for municipalities and highway engineers, determining the effects of different elements on pavement design, construction, and maintenance is their key responsibility. This study examined the impact of four climatic factors – rain, snow, solar radiation, and wind on the in-service performance of pavements. In this study, system dynamics along with causal and effect diagrams were employed. The reinforcing loops for each of the mentioned factors were analyzed, and recommendations were provided. The recommendations included: 1) optimizing the design of hot mix asphalt (HMA), 2) incorporating additive materials in pavement design, and 3) factoring in climatic conditions during the design and construction of pavement roads.
