I am looking for information about landscaping gravel. What is a good inexpensive gravel?
Question:I am unsure of what types of materials these refer to. I need an inexpensive quarter size or smaller type of gravel. #2a is regular driveway gravel right?
What do these mean?
2A Material (2A Modified=GABC=DGA)
AASHTO# 1 (Ballast)
R-3 Rip Rap
R-4 Rip Rap
R-5 Rip Rap
R-6 Rip Rap
R-7 Rip Rap
R-8 Rip Rap
Rustic Red AASHTO# 10 (Grit, Screenings)
Rustic Red AASHTO# 3 ("1½" Clean="3A Clean")
Rustic Red AASHTO# 57 (2B)
Rustic Red AASHTO# 8 (1B)
Thank you in advance for your time...
Answers:
I'm not sure about the 2-A material, but the last time I had gravel put on our driveway it was #57, about 3/4" stone. #8's are smaller. The ballast and rip-rap are all big rocks. The screenings are like sand and used for base material.
those are road constructions specs and stone blend gradations.
See your local landscape yard and ask for pea or river gravel. it should be as inexpensive as any other gravel.
