Our asphalt products
Highway grade asphalt
HCS Paving offers VDOT and MDSHA approved asphalt mixes of all sizes and types and can provide specialized mixes for any project
9.5mm asphalt
No minimum project size required
9.5mm asphalt is the most common type of asphalt. when you look at a road or parking lot surface paved within the last 15 years most likely it was paved with this material. so why is it so common? Because it is made with smaller stones and more sand to allow for a smoother surface overall it is great for overlays and surface layers and is definitely prettier than other mixes but it need a solid foundation beneath it so it is not recommended to be used direct over unsettled stone bases
12.5 mm asphalt
Minimum project size 2,000 square feet
12.5mm asphalt is larger than 9.5mm but is still classified as a surface mix or sometimes and intermediate mix. it is not as commonly used but it does have many advantages mainly being that the larger stones provide a higher tensile strength for the asphalt while still being smooth and tight enough to keep out water and provide a smooth ride. If your driveway is currently fresh gravel it is recommended to use a 12.5mm layer base before installing a top layer but it also can be used by itself
19mm and other commercial mixes
Minimum project size required 10,000 square feet
these larger base asphalt mixes and specialty mixes are typically reserved for large roadways, parking lots and airport runways as a base material they MUST be paved over with a top coat of either 9.5 or 12.5 asphalt these larger stones proved great strength but they do not compact tight enough for regular traffic or to keep water out. over the years we have seen instances where these products are left without the topcoat in that case these asphalts will have total base failure within 2 years

Tar and Chip
Minimum project size required 15,000 squarefeet
Tar and Chip, Sometimes called Chipseal is almost a lost art. Many companies in MD and VA dont have the equipment or crew to do chipseal. this makes sense because it is a very niche product. most county roads used to be chipseal but have been phased out with asphalt but it does still have a purpose it is a great economical solution for long lanes especially wineries and equestrian centers as it can be stylized with a rustic look it gives the look and feel of gravel but it remains locked in place
Oil based driveway sealcoating
No minimum project size required
It doesn’t get any better oil based equinox sealant straight from the seaboard asphalt plant in Baltimore. This coating does wonders for old, gray, dried out and oxidized driveways. this isnt your typical sealant, this is a liquid asphalt cutback that puts all of the oils that have burned out of your driveway right back into it. the idea is simple asphalt driveways are made of three component sand, aggregate and of course the liquid asphalt. when it turns gray it needs oil to hold it together
