It may also impact the results from FN test (kst and ɛst). The cold recycled mixes with finer RAP had higher ITS, |E*|, and the FN test results but lower FI results compared to those with coarser RAP. The effect of binder was only significant on the ITS result and may also have impact on the results from FN test (kst and ɛst). It is

The Effect of Aging on the Cracking Resistance of Recycled

Fatigue cracking is an important concern when a high percentage of Reclaimed Asphalt Pavement (RAP) is used in an asphalt mixture. The aging of the asphalt binder reduces its ductility and makes the pavement more susceptible to cracking. Rejuvenators are often added to high-RAP mixtures to enhance their performance. The aging of a rejuvenated binder is different from asphalt.

recovered RAP binder. Analytical procedures were developed which can predict the complex modulus of a mixture based upon the properties of the and RAP binder and the percentage of RAP in the blended binder. It was demonstrated that this prediction tool could be used to estimate the amount of RAP in an asphalt mixture.

PDF Binder-grade Bumping and High Binder Content to Improve

protect the environment. Although using recycled asphalt pavements (RAP) and recycled asphalt shingles (RAS) is beneficial in many aspects, asphalt pavements with high RAP and RAS contents are more susceptible to cracking. Aged binder in RAP and RAS makes asphalt pavements more brittle and creates long-term durability problems.

Developing a modern recycled mix design and automatic

Asphalt binder replacement (ABR) and binder grade bumping at low temperature were found to be critical factors in low-temperature cracking resistance as assessed by the DC(T) fracture energy test. Six sections were found to perform well in the DC(T) test, likely as a result of binder grade bumping (softer grade selection) or because of low

In the RAH100 system, the recycled asphalt is heated by a counter-current process. This allows the aggregrate and bitumen to be heated indirectly and protected from overheating. Using this system, RAP addition rates of 100% are possible. The plant is able to produce 240-310tonnes/hour of asphalt, depending on moisture.
