Recommended Asphalt Testing
Recommended Asphalt Testing
(OP)
I am a structural engineer with no background in asphalt paving. As part of a semi truck/trailer inspection/maintenance facility an asphalt parking lot was designed by our civil consultants. I am getting questions about what testing is required of the asphalt pavement. I am forwarding questions to our consultant, but want to educate myself a little before I get his responses.
What testing would you specify for this construction?

RE: Recommended Asphalt Testing
You could also get an extraction and gradation to verify asphalt content and aggregate. Maybe an independant Marshall numbers. You could even go so far as strength testing. However, that extent of testing is usually for roads. It depends on your experience with the supplier.
RE: Recommended Asphalt Testing
The problem with using a lower asphalt content (allowed because of larger aggregate...less surface area to cover on the aggregate), is that larger aggregate mixes tend to ravel and have a rough surface texture if not placed with a bit more care than the usual parking lot gets.
The in-place mix density should be as high as practicable, preferably in the 97 to 98 percent of laboratory density range.
