Carver Construction in-place paving is ideal for severely distressed pavements with potholes, cracking, shoving, ruts, and/or oxidation. The pavement must have a structurally sound base as this process does not correct base failures, and the pavements should be sufficiently thick (5-6 inches) to support the equipment. The existing pavement should be analyzed and the recycled mix designed in a laboratory. In-place paving can also be used for widening and upgrading pavements.
Hint: It is important to understand the reason for the pavement failure and to correct any deficiencies that may pose problems
Some main reasons for doing in Place paving
- be cost effective,
- be environmentally responsible, and
- perform well.
Carver Construction in-place paving uses a train of equipment that mills, screens, and crushes the existing asphalt pavement.
The milled material is then blended with an asphalt liquid and the recycled mix is put back down to form a new pavement structure.
Additional aggregate or other additives may also be blended in to correct the gradation or improve the mix that was originaly created by the CIR.
The recycled mix may be placed with a paver or it may be bladed. An asphalt pavement or a seal coat) is applied. The recycling liquid asphalt may be can be turned into a foamed (water expanded) asphalt cement.
It may have rejuvenator oils or other additives to improve coating, moisture sensitivity and durability. The process moves quickly with minimal traffic delay.
The Benefits of Carver
Construction In-Place Paving
- Aged, distressed pavements are replaced with recycled asphalt mix.
- In-place paving reuses the existing aggregate and asphalt, reducing new raw material and hauling costs.
- Cracked pavement is removed, preventing future reflective cracking.
- Deformations such as potholes, ruts, bumps and shoved pavement are removed.
- Crowns can be re-established.
- Clearances under bridges and curb height can be restored.
- With the proper choice of materials, aged asphalt can be rejuvenated, and poor aggregate gradations can be corrected with added aggregate material.
- In-place paving minimizes the time a lane is closed for re-construction.
- There is excellent public acceptance of recycled materials.
- The recycled pavement can, itself, be recycled when its time has come.
