Abstract: The measures for controlling construction quality of lime-fly bound macadam base of pavement were studied from the respects of selecting materials, designing mix proportion and paving methods. The results as follows: the work would be continuous on spreading. In- conditions of high temperature, the moisture content of lime-fly ash bound macadam would be keeped on rolled work doing, and spreading and rolled work would be quick. After rolled work, maintenance would be kept with moisture within 7 days, in conditions of low tempera- ture, road would be covered with material to prevent it frozen.
