Most people who call us about crushed concrete or asphalt millings are fixing a driveway. They have a dirt or shell drive that turns to mud every summer, or an old paved one that's too broken to patch. Recycled stone fixes either problem for far less than new asphalt.

This guide walks a Pasco County homeowner through the whole job. You'll see how the two materials compare, how much to order, what happens when the dump truck shows up and how to keep the driveway in shape for years. Contractors who want our full product lineup and coverage tables should read our aggregate guide for Tampa Bay jobs.

Here's the short answer. Crushed concrete road base makes the strongest base, and asphalt millings make the best driving surface. Many Pasco driveways use both.

Crushed concrete vs. asphalt millings

Both materials are recycled and both cost far less than quarried stone. They behave differently once you drive on them.

Road base works because of its fines. When you wet it and compact it, the fine dust locks the larger pieces together into a solid layer that can carry a loaded truck.

Millings work because of the asphalt still coating each piece. Florida heat softens that coating, and when you compact millings on a hot day the pieces stick to each other. Every summer of traffic packs them tighter.

You'll also see crushed concrete #57 rock on our price list. It's the clean version with the fines washed out, so water drains straight through it. That makes it good for drainage strips along the edge of a driveway. On its own it stays loose and rolls under tires, so it's a poor choice for the driving surface.


The two-layer build most Pasco driveways need

Pasco's sandy soil shifts and softens when it's wet, so stone laid straight on sand ruts fast. The fix is a compacted base under the surface you drive on.

A driveway that holds up has four layers, from the bottom up:

  1. Subgrade. The existing ground, stripped of grass, roots and dark topsoil, then compacted. Organic soil rots and settles, and the driveway sinks with it.

  2. Fill dirt, where needed. Use it to raise low spots so water runs off instead of pooling. Spread it in thin layers and compact each one.

  3. Crushed concrete road base, 4 to 6 inches compacted. This is the structure. It carries the weight.

  4. Asphalt millings, 2 to 3 inches compacted. This is the driving surface. It binds into a firm, low-dust surface.

Shape the finished surface so rain runs off it. Make it higher in the middle, or tilt it to one side, at about a quarter inch of drop per foot of width. Most gravel driveway failures start with standing water.

You don't always need both materials. Millings alone, 4 to 6 inches deep, work fine on firm ground with light car traffic. Road base alone works on long rural drives, equipment yards and parking pads where looks matter less than cost.


Before you order: walk the site

Ten minutes on site before you call saves a second delivery and a driveway you have to redo.

Look for standing water first. If puddles sit in a spot a day after a summer storm, that spot needs fill dirt and a slope before any stone goes down. Stone poured over a low spot turns into a pothole by the next rainy season.

Find your septic tank, drainfield and irrigation lines. A loaded dump truck is heavy enough to crack a tank lid or crush a buried pipe. Flag them before delivery day so the driver can stay clear.

Check your HOA rules if you have an HOA. Some Pasco communities limit gravel or millings driveways, and it's cheaper to ask now than to tear one out later.

If the driveway meets a county road, call Pasco County before you build the apron where the two connect. Work in the county right-of-way can need a permit.

Finally, measure. You need the length and width of the area in feet and a rough idea of how deep each layer will be. That's all we need to quote the job.


How much to order: two worked examples

A single-car driveway, 12 feet wide and 50 feet long, takes about 12 tons of road base and 9 tons of millings. A two-car driveway the same length takes about 20 tons and 15 tons.

Here's the math so you can run your own numbers. Multiply length by width in feet, then by depth in inches divided by 12. Divide by 27 to get cubic yards.

\text{cubic yards} = \frac{L \times W \times (D \div 12)}{27}

Multiply cubic yards by about 1.4 to estimate tons. Then add about 15% for compaction, because stone shrinks when you pack it down.

Weight per yard varies a little by material, so we confirm the tons when you call. Our coverage tables show square feet per yard and per ton at other depths.


Dump truck delivering a load of asphalt millings to a Pasco County property

Delivery day: what to expect

Most orders go out within about two business days of your call. We deliver Monday through Friday.

The truck needs a clear path in, firm ground under the tires and open sky above the dump spot. The bed rises high when it tips, so check for power lines and low tree limbs. A soaked lawn after a storm can rut badly or trap a loaded truck, so a firm spot near the street often beats the perfect spot in the backyard.

Decide where you want the pile before the truck arrives. The driver drops the load where you point, and you're responsible for that spot on your property. Mark it with a tarp or a couple of stakes if you won't be home. If you want the stone spread along the driveway from the tailgate instead of dumped in one pile, ask when you order.

If you're ordering both road base and millings, have the road base delivered first. You'll want it spread and compacted before the millings arrive, and a pile of millings sitting on your work area just gets in the way.

Spreading and compacting

Compaction makes or breaks a recycled driveway. Loose stone, however good, ruts under the first heavy rain.

  1. Spread the road base. A skid steer or a tractor with a box blade makes quick work of it. On a small job, a flat shovel and a landscape rake will do.

  2. Dampen it. Spray it lightly with a hose. Damp road base packs much tighter than dry, but soaked base turns to mush.

  3. Compact in thin layers. Work 2 to 3 inches at a time with a plate compactor or a small roller. Both rent by the day at most equipment rental stores.

  4. Set the slope. Shape the crown or side tilt before the final pass on the base. Fixing it in the millings layer is much harder.

  5. Spread and compact the millings. Do this on a hot, sunny day if you can. Heat softens the asphalt coating and helps the pieces bind.

You can drive on the finished surface right away. Millings keep tightening up over the first few weeks of summer traffic, so expect them to look a little looser at first than they will by fall.

Keeping it in shape

A recycled driveway needs a little attention once or twice a year, mostly after the summer rains.

On crushed concrete, tires push loose stone out of the wheel paths and into the middle and edges. Rake it back into the ruts and tamp the low spots. Every few years, add a ton or two on top to replace what's worked into the ground or washed away.

On millings, the usual problem is a pothole where water sat. Clean out the loose material, fill the hole with fresh millings, wet it and tamp it hard. Some owners also spray an asphalt emulsion over the surface after the first year for a tighter, darker finish.

On both, keep the slope. If water starts pooling, fix the low spot right away. Left alone, a puddle turns into a rut within one rainy season. Keep grass and weeds trimmed back from the edges too, since roots break up the edge and let water in.


What it costs

For the two examples above, the stone runs about $200 to $360 for a single-car driveway and $340 to $600 for a two-car driveway, before delivery.

These use our current yard prices of about $8 to $15 a ton for road base and $12 to $20 a ton for millings. Prices move, so call for today's number.

Delivery starts at $100 a trip and goes up with distance from our Hudson yard. You can keep it down by putting everything you need on as few trips as possible. If you're also ordering fill dirt or #57 rock for drainage, order it with the rest.

Add a day of equipment rental if you're doing the work yourself. Even with that, a recycled driveway costs far less than a new paved one.


Questions we hear a lot

Can I put millings over my old shell or dirt driveway?

Yes, if the old surface is firm and drains. Scrape out the soft spots, fill the ruts with road base and compact them, then lay the millings on top. If the old driveway sits lower than the yard around it, raise it with fill dirt first.


Will millings smell or track onto my pavers?

Fresh millings can smell like asphalt for a few hot weeks. They can also leave dark marks on light concrete or pavers until they bind. A hard edge where the driveway meets light-colored surfaces keeps loose pieces from walking onto them.


Can I build it during the rainy season?

Yes, but plan around the storms. Soaked sand won't compact, and road base that's too wet turns to mush under the compactor. Give the ground a dry day or two after a heavy rain before you start.


How long will it last?

That depends on the base and the drainage far more than the stone. A driveway with a compacted base and a good slope holds up for years with light upkeep. One laid straight on sand with no slope starts rutting in its first summer.


Can I get rid of my old concrete driveway at your yard?

Yes. We take clean concrete free at our Hudson yard, Monday through Friday. It needs to be free of trash, wood and rebar. Our post on where to dump clean concrete and dirt in Pasco County has the details.
