Asphalt Materials:

• Class B or 1/2" HMA (Hot Mix Asphalt)

Standard grade asphalt mix is currently used on most commercial asphalt projects. The aggregate used in this mix is a combination of 1/2" down to sand. PG-64-22 is the standard grade oil used in the Pacific Northwest region. Oil content is approximately 5% in 1/2" HMA.

• Class B Modified

Identical to standard Class B mix but has a higher ratio of sand added to give a less rocky appearance. A very common mix is used for driveways and overlays because the added sand gives a cleaner finish when paving in more difficult situations than wide open parking lots or roads.

• Class G or 3/8" HMA

Very similar to 1/2" HMA, but the aggregate used is 3/8" down to sand. It is used to create a tighter finish desired for tennis courts, running tracks, or very thin driveway overlays.

• ATB (Asphalt Treated Base)

ATB is used as a base application instead of crushed rock. ATB's aggregate is 1 1/4" down to sand. Oil content in ATB is only 4% of the mix. ATB is used as a good hard work surface during construction on commercial projects and is eventually overlayed with Class B or 1/2" HMA to provide that final finished "look."

• Crack Filler

Commonly called AR-4000 or a similar type of product that contains rubber. It is heated up to liquid form and poured into cracks or joints in asphalt to reduce the chance of water infiltration into the subgrade.

• Seal Coat

A slurry-type product used to coat existing asphalt like a paint. A seal coat is used to create the new uniform black "look" and will also help protect the asphalt from gas and oil leaks.

Crushed Rock Materials

• Base Course - 1 1/4" Minus

Base course crushed rock is used in applications where more stability is needed and not so much of a tight finish is desired. A base course is used when the depth of rock being placed is greater than 4" or when the subgrade is less than ideal.

• Top Course - 5/8" Minus

Topcourse crushed rock is used in applications where a tighter finish or more precise grade is desired. Top course is generally used in preparation for asphalt paving or in crushed rock-only situations.

• Grindings - RAP (Recycled Asphalt Product)

Recycled asphalt or grindings are now being used as part of the aggregate product in some asphalt mixes. It can also be used in lieu of crushed rock in preparation for asphalt or for grade-only applications. Once graded and compacted, grindings can provide a very stable, suitable, and rather inexpensive driveway or parking surface.
