Superpave stands for SUper PERfoming Asphalt PAVEment. It is a performance based standard of test procedures for Asphalt concrete. Generally, one will either use Superpave or Marshall.

How does the federal Superpave program improve national road durability?
Superpave involves a volumetric mix design aimed at resisting wear and cracking due to low temperatures and a liquid-binder specification. In the late 1990s, one-third of all hot-mix asphalt projects were Superpave

What products aimed at improving highway construction and operation methods were developed by theStrategic Highway Research Program?
a new road-surfacing material known as Superpave, spray-injection technologies for filling potholes, bridge management software, and concrete anticorrosion technologies.
What are the different grades of asphalt?
Well, the traditional superpave grade is on the order of PG ##-##, this means, for example. A grade of asphalt, say, PG 70-40 is a mix where the 70 stands for the asphalt temp max over the next seven days after layment of 70 degrees and the min experienced temp the grade should encounter is 40 degrees. This means, that this PG 70-40, is where the 70 degrees is the layment temp max and the min temp to ever encounter is 40 degrees. This mix uses high grade crude oil and aggregate. Other grades use typical crude, modifiers and aggregate depending on the roadway. If your question pertains to what aggregate size, type of modifier or crude selection, this is something that you would need to engineer. Far to complicated to detail in this section. Thanks,
