sphalt producers have been recycling for more than 30 years and recycled asphalt pavement (RAP) has become the number one recycled material in the US with about 67 million tons recycled in 2011. Despite this impressive record in many areas of the country there is more RAP available than can be used. The limiting factors range from specification limits and equipment capabilities to process/quality control.
Is the Asphalt Industry maxed out on RAP use? While it may seem so to some, how is it that the Japanese put 80% RAP in their base mixes and 65% their surfaces? And Japan does not have any drum plants! Clearly, they know something we do not.
What about other forms of asphalt technology? Cold recycling has been around for as long as HMA recycling. There have been many advances in materials processing, binders and central plant mix production over the years. Is it time to revisit cold recycling?
There are opportunities for increasing the RAP reuse in asphalt pavement construction. One opportunity being looked at in Virginia is cold central plant recycling (CCPR) where RAP, with small percentages of asphalt emulsion or foamed asphalt, is blended at a central plant to produce an engineered mix as a base below a new asphalt pavement surface. CCPR offers an opportunity to increase the utilization of RAP for asphalt producers that have excess RAP. CCPR can open new markets for an asphalt producer in CCPR base material, RAS utilization and maximum recycling of available materials.
In this session you will learn:
- Advantages of CCPR
- Research results
- Design and construction of CCPR mixes
