The Box Test

With the variety of different makes and models of slip formed paving machines and various operating procedures, to design a slip formed pavement laboratory test method could be very complex and expensive.  A useful test should quickly and easily evaluate the ability of a mixture to be consolidated and subsequently hold an edge.  Of all the slip formed pavement components, the vibrator contributes the majority of the energy applied to consolidate concrete.  In order to closely mimic the consolidation of a slip formed paver, a laboratory test was developed to evaluate the performance of a mixture to a standard amount of vibration and to hold an edge.
