Pavement is recycled in-situ using the recycling assembly by grinding existing pavement, adding fluid asphalt to the pavement, optionally adding supplemental pavement, and mixing the fluid asphalt with the existing and/or supplemental pavement. The mixture is then extruded at the proper height by an adjustable screed.

Pavement condition surveys are performed each year on over 1,200 miles of streets. Information from the annual surveys identifies specific areas where ...
The repair area needs to include all areas that have developed voids under the concrete pavement. This area typically extends beyond the boundary of the failed areas. It is a normal practice to determine the limits of the repair by evaluating the extent of the distress by visual observations only.
With its national headquarters in Charlotte, NC, RENOVA provides asphalt repair equipment and solutions that save time and money.

Introduction. Benefits of Recycling Asphalt Recycling of asphalt pavement can save money for local governments and other purchasers, create additional business opportunities, save energy when recycling is done on site, conserve diminishing resources of aggregates and petroleum products, and help local governments meet the goal of reducing disposal by 50 percent by the year 2000.
Oct 11, 2021· Asphalt pavement mixture was prepared using asphalt AC60/70 and CFA was added to the mixture at percentages of 0%, 5%, 10%, and 15%. NFA was also used as an additive to asphalt pavement mixture with the same percentages. The rutting factor of asphalt pavement incorporating CFA and NFA was measured at 55 °C and 65 °C.
Full Depth Recycling-Foamed Asphalt (FDR-FA) Full Depth Recycling-Cement (FDR-C) Hot In-Place Recycling (HIR), not common in California ; Although flexible pavement recycling strategies are capable of treating many different types of distress, not all rehabilitation projects are good candidates. Some strategies are better suited to treat ...
1. Cold In-place Recycling or cold in-place recycling-partial depth (CIR) – partial depth pulverization (2 to 5 inches) of the asphalt bound layers in a pavement, addition of a recycling agent, emulsified asphalt or foamed asphalt, mixing of the recycling agent and …
pavement maintenance patching. The construction methods for these types of patches can vary significantly after the setting up of the common traffic control phase. For smaller size patching the cement or other binder additive is usually spread by bags and by hand and the mixing is undertaken using a mixing head fixed to a skidsteer machine.
Reclaimed Asphalt Pavement (RAP) Introduction Reclaimed Asphalt Pavement (RAP) refers to the removed or reprocessed pavement materials which contain asphalt and aggregate materials. The elements are generated as a result of pavement removal especially during resurfacing, reconstruction or when retrieving buried utilities. RAP usually form a high quality and well aggregates when properly ...
There are many economic and environmental advantages to recycling and rehabilitating asphalt pavement. Ingevity's Indulin® emulsifiers are used in emulsions for a variety of green paving processes such as cold in-place recycling, full-depth reclamation, and base stabilization. Cold In-Place RecyclingCold in-place recycling (CIR) is done without heat and using of existing road materials.
Asphalt shingle recycling not only reduces the requirement for the materials that the shingles are replacing such as binder and aggregate in the asphalt pavement market, but also reduces the use of landfill space.2 Shingle recycling may also reduce the emission of potentially hazardous
pavement repair technologies: cold recycling and hot recycling. Through cold recycling technology, a new asphalt mixture is filled after removing diseased pavement. This process will result in wasted asphalt mixture. In addition, the strength of the repaired asphalt pavement decreases given the joint between the old and new asphalt mixtures [3, 4].
Pavement Recycling and Reclaiming Pavement recycling and reclaiming is another important process for rehabilitating asphalt pavements. Construction equipment and materials have greatly evolved over the last few years to allow for low-cost, in-place recycling and reclaiming of asphalt pavements. Optimizing Pavement Rehabilitation
Mar 08, 2016· The cold in-place recycling process involves specialized plants or processing trains, whereby the existing pavement surface is milled to a depth of up to 150 mm (6 in), processed, mixed with asphalt emulsion (or foamed asphalt), and placed and compacted in a single pass.
A process for recycling asphalt pavement by serially heating and milling the asphalt until the desired depth of asphalt has been removed and then mixing the heated asphalt with additives, if needed, for reapplication to the pavement.

Hot Mix Asphalt, Chip Seals, Slurry Surfacing, Fog seal Hot Mix Asphalt, Chip Seals Performance Measures Removal of surface distresses, helps mitigate reflective cracking, improves smoothness and profile Eliminates pavement distresses, increases structural capacity, & restores profile Keys to a Successful/Quality Recycling Project
Apr 05, 2018· Using recycled asphalt pavement saves the taxpayers in the U.S. between $1.8 and $2.5 billion annually as well as individual project goers. Recycled asphalt is stronger, more durable, and cheaper to produce than new asphalt, making the refurbishing of damaged roads more affordable for the taxpayers funding a majority of it.
Cracks are the first step in pavement deterioration. They will allow moisture, chemicals such as gasoline and oil, and the sun's ultraviolet rays to penetrate the asphalt concrete. This accelerates pavement breakdown. Proper repair of cracks ¼ inch wide or larger is …
Hot In-Place Recycling. Hot in-place recycling (HIR) is a less common form of hot asphalt recycling. There are three basic HIR construction processes in use, all of which involve a specialized plant in a continuous train operation (FHWA, 2001c  ): Heater scarification (Figure 1). This method uses a plant that heats the pavement surface ...
Dec 03, 2019· In the long-term use of asphalt pavement, cracks, pits, ruts, and other damages to roads will inevitably occur and therefore must be repaired [1, 2]. There are two kinds of pavement repair technologies: cold recycling and hot recycling. Through cold recycling technology, a new asphalt mixture is filled after removing diseased pavement.
A machine for recycling macadam highway pavement is disclosed. A pickup device removes crumbled pavement material from a roadbed site, and heaters heat the material as it passes through the machine. An applicator applies liquid asphalt to the material to form a rejuvenated mix. Simultaneously, roadbed heaters heat the roadbed site, and an applicator applies liquid asphalt.
Isolated asphalt patching is also another common form of preventive maintenance repair. While patching is an option, we limit the patching to repair areas with fatigue cracking and potholes. Once pavement conditions become fair or poor, thin pavement overlay or a mill and overlay can be considered to extend the pavement useful life by five to ...

Sep 17, 2018· Asphalt recycling starts with recycled asphalt, which contains reprocessed pavement. According to the Federal Highway Administration, reclaimed asphalt (otherwise known as RAP) starts with old, broken or damaged asphalt. "Reclaimed asphalt pavement (RAP) describes removed and/or reprocessed pavement materials containing asphalt and aggregates.
