Durable Rubberized Asphalt Proves Its Worth in Phoenix

Reduced budgets for road repairs because of a population plateau and rising costs of paving materials have led the City of Phoenix, Arizona, to use a greater share of rubberized asphalt for new paving jobs in order to save money in the future because of its added durability. Because of the intense sunlight in the Sonoran Desert where Phoenix is located, conventional asphalt degrades more rapidly, as the sun oxidizes the material, and fine sands start raveling out. Rather than the typical approach of applying a slurry seal, the city is turning more often to rubberized asphalt. The city and state are well-known pioneers in its use. Production methods, costs, and technical explanations about how it works are given. Phoenix has overlaid more than one-third of its road miles with rubber, polymer or some type of modified asphalt binder.
