Abstract：To solve the obvious shrinkage and temperature shrinkage of lime soil with easy cracking of road base layer, based on the viscous filling of the #1 construction in the West Extension Line project of Wenchang Road, Yangzhou, the unconfined compressive strength of lime soil was investigated, and the effects of slag and fly ash on the strength of lime soil were analyzed by SANS universal testing machine. The results show that the unconfined compressive strength of sulfur-containing lime soil is increased with the increasing of slag content, and the unconfined compressive strength of sulfur-containing lime soil with the age less than 180 days is increased greatly and increased slightly with the age more than 180 days. With the increasing of fly ash content, the unconfined compressive strength of sulfur-containing lime soil with the age less than 30 days is increased linearly, while that with the age more than 30 days is decreased continuously.
