ADOT’s Use of Crumb Rubber in Asphalt Pavements
The Arizona Department of Transportation (ADOT) has used crumb rubber from ground tires since the late 1960's to primarily reduce reflective cracking. In 1988,
ADOT started to use crumb rubber mixed with hot asphalt, commonly referred to as asphalt rubber as a binder in hot-mix asphalt. Typically, these...

Arizona’s Experience with Asphaltic Concrete Friction Courses
Over the past several years the Highway Research Community has placed a major emphasis on “keeping our roads satisfactory” or perhaps the more definitive term
would be “safe”.  In the area of pavements the research has been principally concerned with the frictional quality of pavements and the effect...

Asphalt Rubber Approach To Low Cost Low Volume Streets
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...
