On average, P608H material is about twice as expensive as P608 material, largely due to a substantially higher volume ofBased on the results so far, Dillin suspects P608H could aggregates.

The extra heavy material seemed like it did a really good job filling in the weathering that was on the surface and reducing the raveling issues, Dillin reports. It didnt completely fix them, but it did noticeably reduce them.
