“Needed a proper turnaround at the end of our gravel driveway so the plow truck could stop backing halfway into the road. About eight tons of road base did it, spread and tamped over two afternoons. The tri-axle got up our hill fine even with a skiff of snow already down, and the driver waited while we walked him through exactly where we wanted it dumped.”

Glacial till and ledge close to grade can leave little room for water to move downward. Type A Gravel forms a firm supporting layer when compaction brings its crushed particles, gravel, and fines into close contact. It suits camp roads, driveways, and work expected to handle sustained vehicle or equipment traffic, particularly when spring thaw softens the ground.
When drainage must run sideways over ledge, establish that route before placing the base and compact it into a stable course. This helps the layer spread traffic pressure across the subgrade instead of concentrating it in soft spots. Careful base preparation is especially useful through freeze-thaw conditions and mud season.

Common Uses
Road & Highway Construction
For road and highway work, road base goes below asphalt or concrete pavement. It creates a firm layer that spreads vehicle weight over the subgrade, which is especially important through deep frost and freeze-thaw cycling.
Heavy-Duty Driveways
Road base reinforces driveways used by large trucks, trailer loads, equipment, or steady commercial traffic. It helps limit rutting and wear from repeated heavy use.
Jobsite Entry Roads
Build temporary or lasting construction-site routes with road base. It supports equipment travel and forms a dependable surface in wet conditions so work can continue.
Commercial Parking & Loading Areas
Install road base under commercial parking, loading docks, and industrial yards used each day by vehicles and equipment.
Why Choose Type A Gravel
Maximum Load Capacity
Road base serves high-load areas with loaded dump trucks and industrial machinery. Compaction spreads the load through the base and helps avoid damage from concentrated weight.
DOT Specifications
Review Department of Transportation base course aggregate specifications when they apply to your project.
All-Weather Performance
With proper installation, road base stays stable through wet, dry, and freeze-thaw weather. Tight compaction reduces water entry that may soften less dense materials.
Economical for Large Projects
Road base provides a commercial-grade alternative to paved surfaces at a fraction of the cost. On broad access roads, parking areas, and work yards, it combines strength with value.
Frequently Asked Questions About Type A Gravel

Turnaround packed down solid in a week
The turnaround by our garage needed six tons of road base to stop the spring mud. The tandem dumped it in one pile right on the mark. Packed down solid within a week, no soft spots anywhere.

Great base, just came up short
Our little condo association put in an overflow parking strip along the back fence, ten tons of road base per the online calculator. It compacted up nicely with the rented roller and drains fine even in a downpour. Only issue is we came up about two tons short and had to call back for a second small delivery to finish the last corner.

A turnaround that finally stops the plow
Needed a proper turnaround at the end of our gravel driveway so the plow truck could stop backing halfway into the road. About eight tons of road base did it, spread and tamped over two afternoons. The tri-axle got up our hill fine even with a skiff of snow already down, and the driver waited while we walked him through exactly where we wanted it dumped.

Base held under harvest truck traffic
Up here we deal with potato harvesters and semis all fall, so the old lot behind the barn needed real base under it. Fifteen tons of road base went down and got rolled with the tractor before harvest trucks came through. Maine Rock Supply got it up to Aroostook County within a week. It handled the weight without pumping mud through the surface, more than the pit road ever did alone.

Farm lane stopped flooding every spring
The lane out to our back field turns into axle deep mud every spring once the frost lets go, and hauling hay through it was getting risky. We put down twenty two tons of road base the length of the worst stretch, right before planting season. The driver ran a tandem truck out our dirt road and spread three loads exactly where we flagged it with stakes. Maine Rock Supply worked around a two day window we had between rain systems. A year later, after another full mud season, the lane held firm under the tractor and the baler both, no ruts, no standing water.
