PURPOSES: The purpose of asphalt pavement reducing surface temperature by using Pipe cooling system is to make pleasant city life environment. METHODS: We considered building condition to lay the pipes under asphalt pavement and figured out that temperature reducing effect with pipe cooling system. In addition, we guessed rutting through wheel tracking test with a laid the pipes under asphalt mixture and performed fatigue cracking through a flexural fatigue test for performance evaluation of pipe cooling system. RESULTS: When pipe cooling system worked, the temperature of pavement model reduced quickly in test. The system can turn down the degree by 4 or 5 quickly as well. It didn't affect rutting to lay the pipes under the pavement, but it can get damaged to asphalt pavement in early stage by the result of performance evaluation. CONCLUSIONS: We figured out that pipe cooling system can turn down the temperature of aspalt pavement surface through tests. We suggest that pipe cooling system should be considered one of the effective way to solve urban heat island problem.
