Asphalt Emulsions in Cold Recycling
An asphalt emulsion consists of three basic ingredients:  asphalt, water, and an emulsifying agent.  In some instances the use of a stabilizer is needed.  In making an
asphalt emulsion the object is to disperse the asphalt into water...

Burlington County Closed Loop Used Tire Recycling Facility
More than 282 million scrap tires, or approximately 1 tire per person, are generated each year in the United States.  More than 75 percent of these scrap tires are
placed in landfills and stockpiles or dumped illegally.  Some estimates indicate that illegal dumping may...

Petroleum Contaminated Soils in Highway Construction
There are between 0.8 to 1.2 million leaking underground storage tanks (USTs) mostly storing petroleum by-products such as gasoline and fuel oil.  Leaking petroleum
products from USTs contaminate soil and move to contaminate ground water. In 1984 US Congress added Subtitle I to the Resource Conservation and...

Placement and Compaction of Thin Lift Asphalt Overlays
This presentation defines a thin lift as less than two inches compacted thickness.  Thickness is partly determined by the anticipated traffic density and partly by the
need to reduce stress levels in the underlying layers.  Thin lifts should be used for relatively low traffic density requirements...

Recycling of Waste Tires in Asphalt Paving Construction
Each year approximately 9 – 10 million waste tires are generated in New Jersey.  Historically, 85% - 90% of these waste tires were going to a combination of landfills,
stockpiles and illegal dumping.  While no data is available on a breakout of the percentages going to landfills as opposed...

Recycling Scrap Tires to Build Artificial Reefs
During the course of the project more than 650 tons of scrap tires were removed from a tire dumpsite in Tabernacle, NJ.  These were recycled into 807 artificial reel
units, which were deployed on two artificial reef sites.  The project demonstrated that current methods...

Rubberized Rap Recycling, Ferry Street, Newark, NJ
With the incipient Federal regulations mandating the use of ground tire rubber, one of the biggest concerns of the asphalt industry is the recyclability of asphalt
pavements containing ground tire rubber.  Currently, recycling of asphalt pavement is routine in most states.  Recycling is an economically...
