1、 Scope of application

冷再生機(jī)出租為保證路床厚度范圍內(nèi)的CBR值和壓實(shí)度達(dá)到規(guī)范要求，全線路床上部36cm厚采用6%水泥土處理。針對(duì)低填淺挖路基，當(dāng)路基填方高度或挖方深度≤155cm時(shí)，路床下部44cm厚換填4%的水泥土處理，路床上部36cm厚換填6%水泥土處理。

In order to ensure that the CBR value and compactness within the thickness range of the roadbed meet the specification requirements, the upper part of the roadbed 36cm thick is treated with 6% cement soil. For low filling and shallow excavation subgrade, when the filling height or excavation depth of subgrade is less than or equal to 155cm, 4% of cement soil is replaced with 44cm in the lower part of roadbed, and 6% of cement soil is replaced with 36cm in the upper part of roadbed.
