ASPHALT COLD IN PLACE APPLICATION

What Is Cold In-Place Recycling

ashphalt paving train

The milling of a deteriorated asphalt pavement material that has reached the end of its useful life. This includes asphalt wearing and asphalt base course material. This milling machine then cuts and sizes the old asphalt. The material is then mixed in-place with a new asphalt binder, paver laid and compacted to the desired depth and scope of the project specifications.

 

Features & Benefits

• Conserves energy and natural resources

• Environmentally friendly

• Improves mix characteristics

• Cracking eliminated or reduced Improves cross slope

• Restores reveal to concrete curbs and gutters

• Cost effective

• Saves time

 

Option (A) Equipment For CIR Train

• Emulsion tanker for CIR train.

• Down cutting milling machine 10 foot cutting width.

• Conventional paver 16 foot minimum screed width

• Steel drum vibratory roller (12 ton)

• Pneumatic tired roller (25/30 ton).

• Small milling machine for utilities

Option (B) Equipment For CIR Train

• Emulsion tanker for CIR train.

• Cold Recycler

• Steel drum vibratory roller (12 ton)

• Pneumatic tired roller (25/30 ton).

• Small milling machine for utilities

Asphalt pavements eventually will develop distress such as:

  • Cracking Raveling
  • Pot holes
  • Poor Ride Quality Traffic,

weather and hardening of the asphalt binder all contribute to these problems.

 

CIR- Candidates

Core Samples Are Essential In Any Cold-In Place Recycling Project

Road Preparation For CIR

• Any damaged cross pipes should be replaced

• Drainage and water problems should be addressed

• Any vegetation growing on the pavement should be removed

• Shoulder or pavement widening should take place before CIR

 

Things to Consider in a CIR-QC/A Plan

• All meters and computers should be calibrated
• Recycling additive – check on specifications and compliance.
• Recycled mat smoothness
• Moisture added to RAP
• Compacted density
• RAP gradation
• Moisture content before overlay
• Recycling additive content
• Depth of pulverization/milling
