| Abstract: | The seal coat of high type highway plays a conclusive and fundamental role in determining the waterproof performance of the whole road surface. Consequently the road life cycle is prolonged and the maintenance effort reduced. On the basis of the Kai Yang Expressway construction practice, the application of single hot bituminous surface treatment with premixed macadam to the lower seal coat is discussed and a foundation for the further study of bituminous seal coat design and construction given. |
