Arizona, Cost, Performance
With the rapid growth of the City of Phoenix, islands of non-paved streets developed causing dust and bottlenecks that
had to be paved.  These were low-volume streets with not willing property owners to pay for the cost of construction.  
Alternate pavement designs were developed using asphalt rubber on a variety of bases.  Asphalt rubber was applied at
–50 gallons per square yard (2.26 liters per square meter) followed by a crushed stone chip directly on native soil, soil
cement, crushed aggregate, soil cement-asphaltic concrete, old asphaltic concrete and old Portland cement concrete.  
Asphalt rubber has given the pavement an additional unmeasureable serviceability over the variable types of bases.  
This type of construction has thus far given up to eight maintenance free years that otherwise would require major
reconstruction on existing surfaces.  The asphalt rubber has given the low cost, low volume streets an added pavement
life that is still being measured to date.
