Research on Preparation Technology of Exposed-Aggregate Cement Concrete Pavement

Abstract:

Through a large number of laboratory tests，authors study the preparation technology of exposed-aggregate cement concrete pavement, such as the spraying time, spraying dose of exposed-aggregate agent and the flush time. According to the tests results, the spraying time of exposed-aggregate cement concrete declines constantly with the increase of temperature and the appropriate spraying dose of exposed-aggregate agent is determined. The higher the temperature the earlier the flush time. There is a bigger time interval, more than 10h for normal temperature between the earliest and latest flush time.
