Even though UBCO is a rehabilitation method, the construction methods are very similar to that of new concrete pavement construction. The UBCO construction procedures are as follows:

If the UBCO is placed over CPCD, shatter slabs must be removed and replaced. If the UBCO is placed over CRCP, punchouts should be repaired with full-depth repair (FDR) methods. Spallings, whether they are shallow or deep, do not need to be repaired. Sections 2 and 3 detail the methods that should be used to properly repair these distresses.

Place the interlayer in accordance with HMA specifications and the details of construction method in Chapter 6.

Once all the distresses requiring repairs are completed and the interlayer is placed, the UBCO is constructed using the same methods and following Item 360 and the pertinent pavement standards as when constructing a new concrete pavement. Chapter 9 discusses these construction methods.
