Hard asphalt has been applied and studied on Chinese highway asphalt pavement for nearly 20 years. Although it has excellent road performance, it has not been applied on a large scale. The main reason is that there is no clear technical standard and technical system for hard asphalt, which restricts the popularization and application of hard asphalt as a good material in the highway engineering. Therefore, it is urgent to formulate standards for hard asphalt products of highway engineering in China. In order to promote the large-scale application of hard asphalt for asphalt pavement in China, a draft definition of hard asphalt for highway use and a draft technical standard for engineering are proposed through a large number of tests and research analysis of various samples, drawing lessons from the current technical specifications and relevant international standards for hard asphalt.
