INITIAL CRACK PREVENTING PRE-STRESSED CONCRETE PAVEMENT METHOD

摘要

The present invention relates to a prestressed concrete paving method for suppressing initial cracks. The method first gives tension corresponding to stress causing cracks just before cracks of a concrete pavement (10) are created to promote mechanical cracks, property sets the time and strength of initial tension to prevent damage to the pavement (10) while curing by early introduction of tension, and additionally applies regular tension when curing of the pavement (10) is completed. Cracks of a prestressed concrete pavement (10) can be drastically suppressed to improve structural stability and durability of a prestressed concrete pavement road.
