This innovative road reconstruction process is a cost-effective alternative to more traditional methods of rebuilding asphalt roadways. It is used when existing pavement has aged, cracked or deteriorated beyond the point that normal road maintenance operations are practical or cost effective.
With our single-unit Cold In-Place Recycling Train, a highly-efficient milling machine excavates the existing asphalt pavement to a depth of 3"-5" to eliminate cracks, ruts and oxidized asphalt. The down-cutting action of this specially-designed milling machine sizes the asphalt and immediately blends it with a specially-formulated asphalt emulsion. This emulsion mixes with the milled pavement and acts as a binder to form the new recycled asphalt pavement. Finally, this new mixture is placed on the roadway by a bituminous paver and compacted as a new and more durable 3"-5" asphalt base course. This new base course is placed at the grade and cross-slope as required by project specifications.
Major road detours and obstructions normally associated with road reconstruction are eliminated with the Cold In-Place Recycling Process. This entire reconstruction takes place in a single lane at a time, allowing traffic to flow unimpeded around the recycling operation. Access into and out of driveways can be provided during construction so deliveries and businesses are minimally interrupted. Another positive aspect of this process is that all of the construction is conducted within a span of approximately 100 feet. This relatively small work area can greatly reduce the delay time motorists generally experience in conventional construction work zones.
Following a brief curing period of approximately one week, a surface course of new hot mix asphalt 1-1/2" to 2" in depth is applied on top of the recycled base to complete the road reconstruction process. The thickness of the new surface mix placed over the recycled base will depend upon the use and traffic loading of the area being reconstructed.
Cold In-Place Recycling has been used since the early 1980's to reconstruct nearly every type of asphalt-based roadway. These projects include "farm-to-market" roads that were constructed without a proper asphalt base, busy residential roads, urban commuter thoroughfares, and major feeder systems for industrial parks. Some roads completed with this process now handle in excess of 15,000 to 20,000 vehicles per day.
Cold In-Place Recycling can be used to rehabilitate all types of asphalt pavement including airport taxiways/runways and parking lots for heavy industrial, commercial and institutional uses.
Cold In-Place Recycling is one of the fastest growing road reconstruction techniques available. It is fast, cost-efficient, and can produce a strong base course using existing road material. When your asphalt roads have deteriorated to the point that they need to be reconstructed, consider utilizing Cold In-Place Recycling to build a stronger road base, save tax dollars, minimize traffic delays, and help conserve our valuable natural resources.
