| Abstract: | After mixing high-quality graded stone with 2% - 2. 5% of the cement dosage,the indoor and outdoor series of tests is done to test the performance of modified graded crushed stone.The test result shows that the incorporation of 2% cement graded crushed stone improves the grass-roots strength and water stability, while avoiding the grassroots gravel cement shrinkage cracking,water damage and inherent flaws.This method also worth promoting to related construction project. |
