Application of Construction Technology of Cement Cold In-place Recycling in Main and Medium Maintenance of Pavement

Combined with maintenance engineering of Panshi section of Nation Road 202 in Jilin province,cold recycling construction technology and its performance indexes are discussed,providing referential experience for promotion and application of cold in-place recycling technology in Jilin province.Engineering practice shows that cold in-place recycling technology applied for old pavements has the characteristics of low cost,short construction period,material saving,no damage to subgrade,no pollution to environment and traffic safety which has great significance for natural resources saving and ecological environment protection.
