Abstract A comprehensive durability evaluation system for road cooling coating had not yet been constructed. Aimed at this objective, different new road cooling coatings were prepared based on a variety of selected raw materials, and the cooling effects of different road cooling coatings were determined by means of a field test. The complex coupling environment of temperature, vehicle load, and pollution in the practical application of road cooling coating was simulated. Durability evaluation indexes of road cooling coatings under different composite operating conditions were presented, following which the comprehensive durability of different road cooling coatings was evaluated using a multi-objective grey target decision-making method. Road cooling coatings with superior comprehensive durability were selected. The results demonstrate that various road cooling coatings can reduce the asphalt pavement temperature under the impact of the outside environment. The comprehensive durability of road coatings is obviously improved with the addition of cooling function materials.
