was also heated in a container to a temperature of 155[degrees]C (for 2 hours) which is corresponding to a viscosity of 170 cSt obtained from the viscosity-temperature relationship shown in Figure 5.
Accordingly, three grades of asphalt cement
are used in the bottom layers of the three perpetual pavement test sections: PG 64-22 (stiffer), PG 70-22 (stiffer), and PG 58-28 (softer).

The more common wet process blends the crumb rubber with the asphalt cement
before adding the resulting binder to the aggregates.
Simon Hesp, an asphalt researcher at Queen's University, made headlines recently when he pointed out that at least some of the issues are related to the use of recycled motor oils in asphalt cement
Reclaiming and reusing the asphalt cement
in RAP and RAS saved about $2 billion in 2013 compared to the use of virgin asphalt binder.
binds the aggregate particles together, enhancing the stability of the mixture and providing resistance to deformation under induced tensile, compressive, and shear stresses.

The milled material is then mixed with an asphalt cement
and re-laid over the milled road, a process that has been in use for around 30 years elsewhere.
Some tools you may need will be a ladder, tin snips, gloves, mortar joint compound, and perhaps asphalt cement
. To make your job last the longest, use stainless steel nails on steel flashing to hold it down.
