چکیده
Chemical additives were used in this research to improve the properties of road subgrade layer. Cement, lime, and ferric chloride used. Laboratory tests such as unconfined compressive strength, consistency limits, wheel truck test conducted. The results showed that adding these chemicals soil increases ability work, its resistance, durability. optimum percentage chemical is suitable for addition Al-Nasiriya city 9 %, 10 2 % corresponding cement, chloride, respectively. According strength with increase curing period, which gave good improving soil. As all reduced liquid limit plasticity index increased plastic limit, according track test, at 10,000 passes Rutting depth was 32 mm natural soil, also depths (14, 19, 17 mm) additives,
