This paper introduces grout through screen pipe to reinforce soil mass in the roadbed widening parts with the linkage of old road, which can form a whole structure with under soil mass in the linkage of the road. It can ef ectively improve the bearing capacity of soil subgrade and the linkage of pavement to prevent the uneven set lement which can lead to cracks.
