Hey everbuddy,

So I'm making about 300 meters of somewhat steep driveway on my friends land. I'll be spreading a few inches of "lastre" over it which is road base I guess, like crusher rock of different sizes mixed with dirt. Gonna take like 10 tandem dump truck loads.

On most of these driveways in rural Costa Rica the road base just gets smoothed out and compacted with the backhoe bucket and we call it good. My buddy is somewhat hung up on the notion of renting a roller and compacting it "properly". That sounds nice to me, except I don't really know where to find a small roller that would go up the switchbacks. My buddy has *no* machinery or building experience, I've been doing it for several years now but learned way out in the country where a backhoe is basically all that is available.

I guess I'll start asking at the machinery yards that I know of if they can point me in the right direction for something like that.

Alternately, is it a ridiculous idea to buy a walk behind plate compactor (tamper, the one that looks like a lawnmower had a kid with a clothes iron) and try to compact the road base with it? Like 300 meters of 3 meter wide road, all sloped.

I saw some dudes pulling a tamper uphill with a rope a few months back, like two guys would with a wheelbarrow. But that was just prepping for a driveway apron pour.

Anyways, I could possibly get this job to pay for the tamper if I play my cards right, while keeping the boss happy. I've used tampers before, when I was helping on paving stone jobs and pours many years ago. And theoretically it could work. But what is y'alls experiences/opinions? Is this just ridiculous? Or perhaps a decent excuse to buy a new tool and have it for future jobs.

Thanks!

If there are no rollers to rent, including a 3 pt roller drum (that you fill with water or sand), an option is to just slowly drive a heavy vehicle over it.

Kind of a pain since the tires have a small contact area compared to a roller, but 300' isn't that huge. If your friend has the time, he can just spend a few hours slowly driving back and forth to try to pack it down.

If a dump truck can drive the switchback driving a fully loaded one will compact things well.

I would roll the road with the dump truck and if that’s not possible roll it with the backhoe. Using a plate tamper on that much road will take forever and they’re not self propelled. Pushing one up much of a hill will be a workout.

If there is clay soil I would recommend using a Geo-textile fabric underlayment.

If it's on a hill that is steep enough to involve switchbacks compaction isn't as much concern as erosion. If the road is well crowned and has good ditching on both sides would be my main concerns.

Sebculb, way off topic but I was just watching a motorcycle tourist who went up the mountain north-east of you in the past couple of weeks. Here she is riding up a primitive road similar to what you describe. (She discovers this one dead-ends at a finca).

This excerpt starts @ 5min:30sec where it gets interesting.

Noraly is amazing. 2018-2019 she rode from New Delhi to home in Netherlands. Now 2020-2022 she's halfway from Patagonia to Alaska. A million YT subscribers and 160 million views of her videos. She consistently makes the best videos of remote places that I've ever seen. She posts new YT videos every M-W-F.

Costa Rica seems wonderful. I love Ecuador. Have inlaws there. It is similar - calm, everyone decent. Those two countries have received the most American retirees, for good reason.

I agree it will take along time with a plate compactor, but they do "drive" themselves forward. I only have to pull mine if the ground is too wet/soft. 99% of the time it's just one finger on the bar steering it. Most plate compactors give you a feet per minute spec so you could figure out how long it will take you.

who ever is providing the rock will probably have a roller.

easy way is to pay for a little extra time for the last load truck. have him drive up and down fully loaded a few times.
