| Abstract: | Problems that exist during paving of exposed-aggregate cement concrete pavement including material selection, appropriate amount of exposed-aggregate agent, treatment of exposed-aggregate and so on, are researched. It is found out that the amount of exposed-aggregate agent is a significant factor which affects the penetration depth, spraying uniformity as well as spraying time; temperature is the most outstanding factor that affects the treatment time of exposed-aggregate. The practice of test road shows that exposed-aggregate cement concrete pavement is a new type of pavement with excellent characteristics and great prospect. |
