Placement
Trademarked ReBase is a value added cement treated base/sub-base product manufactured from processed/recycled construction/demolition waste/debris that achieves superior engineering properties and LEED’s compatibility at competitive costs.
Placement
a. Ready to place. ReBase arrives at the jobsite ready to place. It is haul truck delivered on your schedule. ReBase is easily placed with equipment commonly used to grade and compact soils. Thus, no special or costly equipment to use or maintain when you place ReBase.
b. No Mixing. There is no time wasted on reworking and mixing materials.
Rebase is placed like other bases or soils, but it is perishable because it contains cement.
The placement of ReBase is no more difficult than that of other bases. The material comes mixed and ready to use which makes placement fast and uncomplicated. The area should be prepared prior to the delivery of the ReBase. The subgrade should be compacted and moist, but free of standing water. Moisture will prevent the subgrade from removing water from the ReBase. The material should arrive in an end dump or other truck at optimum moisture for compaction within a usual range of -1% to + 2% moisture. If possible, the material should be placed immediately. The proper moisture content should be maintained in the material to insure the proper density when compacted. When placed immediately this should not be a concern. If the material is allowed to sit for extended periods of time the water content may be reduced by evaporation and cement hydration. The material will not reach optimum density if allowed to dry out or is overly wet. Both instances will also have a detrimental effect on cement hydration and bonding within the material. Preparation for the placement of the material is the most convenient way to avoid these concerns.
The material can be placed and shaped with equipment
usually associated with earth work. A bucket, shovel, blade or variation
of these can be easily used to place ReBase in the prepared area. Simply
shape the material to the desired grade and contour using standard equipment
such as a motor grader, front end loader, etc. Then compact the ReBase
to achieve proper density and consolidation. A vibratory plate or roller
should be used for best consolidation of the material. The surface can
then be re-bladed and contoured to achieve final grade. Rolling a final
time with a rubber-tired roller or smooth drum roller can give the material
a more finished look. The ReBase should be kept moist for seven days to
allow curing, but can be opened for use after 24 hours. Asphalt emulsions
and curing sealers can be used to prevent water loss and aid in curing.
