Abstract: In China's coastal areas and inland plains and Intermountain basin are widely distributed in different types of soft soil and its main characteristics is the foundation bearing capacity is low, the ｌｏａｄ deformation larger, which for the highway construction brings many engineering problems. The formation mechanism of soft soil in different regions is different, the characteristics and nature of the different, the role of the road is also different. On the other hand, is being built ｏｒ already repaired the high grade highway, due to various reasons the subgrade strength low, subgrade settlement, pavement slab ｏｒ pavement deformation and other diseases, especially bridge, channel back to Taiwan and the junction of the subgrade to both settlement of different, direct influence of the road roughness, linear smoothness and pavement structure stability. In this paper, the treatment method of soft soil subgrade is reviewed. Keywords: Soft soil subgrade; Treatment method; Review
