Through the analysis of the monitoring data of ultraviolet radiation in Tibet, and compared with the related areas, the distribution and intensity characteristics of ultraviolet radiation in Tibet plateau were obtained. Tibet Plateau radiation intensity equivalent to about three times more than the same latitude as the southern region, and also much higher than in eastern Tibet, the solar ultraviolet radiation is the strongest region in the world. The survey summarized the main characteristics of Tibetan asphalt pavement disease, analysed the strong ultraviolet irradiation, the relationship between Tibetan road disease and strong ultraviolet radiation, and obtained the general rule of the damage of asphalt pavement in Tibetan: ultraviolet radiation→asphalt pavement whitened→asphalt hardening→micro cracks appeared→crack expansion→cracking→water→asphalt peeling (loose), pit slot etc. The origin of this Law in the Tibetan strong ultraviolet radiation, High ultraviolet radiation causes aging of asphalt，losing its original performance, which led to destruction of roads in climate and traffic load, therefore, to strengthen the anti-aging properties of asphalt will be greatly improved Tibet District road usage.
