In order to consider the economy of overall performance evaluation and engineering applications of fiber stabilizer,in recent years,the cellulose fiber stabilizer has become preferred material in SMA building.However,there are different formulations about which is better of using granular cellulose fiber for road construction or loose cellulose fiber for road construction.In this paper,the way with performance test of granular cellulose fiber was compared with cellulose fiber for road construction by experiment.The results show that the way with performance of granular cellulose fiber for road construction is obviously superiority than loose cellulose fiber for road construction.
