The construction process in which cement concrete pavement are formed by rolling with roller. It is characterized by paving with highly harsh cement concrete, asphalt concrete or base paver, and vibration rolling and compaction with roller.
2.0.12 Pre-located steel guesses method
Construction method for expansion joint dowel, contraction joint dowel and tie bar gusset that are pre-installed and fixed on the top surface of base course and meet the required machining precision.
2.0.13 Concrete bricks pavement
Pavement paved with prefabricated cement concrete block for carriage way.
2.0.14 Concrete road curb
The solid strip concrete block used to confine the margins of cement concrete block pavement.
3 Technical Requirements for Raw Materials
