Roman-Road Building on The Farm: Festina Lente

It worked for the Romans, who began their road bed with a course of packed sand, then piled on rubble and tamped it. Thus the fate of their enemies' buildings that the ever-pragmatic Empire wanted gone! Here's an extant bit of Hadrian's Wall in Northumberland, where I made a brief visit in 2009 during a longer walking holiday in the Yorkshire Dales.

My local, Central-Viriginia bit of Roman engineering is neither so malevolent nor thorough. After moving to the old family farm, I found myself in possession of many piles of broken masonry, chunks of cinder-block, and odd stones with a bit of mortar attached. These oddities congregate in un-mowed areas and crop up every winter.

As I clear areas for planting or an expanded bee-yard for our hives, I began to tote the rubble to a road that runs through bottom-land below one of the out-buildings. It's been churned to mud by my tractors as well as a few heavy trucks bringing contractor dumpsters. I've been dealing with a Depression-era predecessor who bordered on hoarding, as many of his era did.

We have a lot of non-useable debris on the site too. I find old boards ripe with rusty nails, thousands of feet of of soggy insulation, decayed plastic containers in heaps that the prior owner wanted to save up "just in case" but never got around to re-using. Getting this stuff--and there are literally tons of it--out requires a heavy vehicle to travel over soft ground.

The bottom road is now the sort of mud that the Soviets honored, in their remark that their two best generals during the German Blitzkrieg were General Winter and General Mud. I've seen photos of Panzers up to the top of their treads, mired deep, in mud that later froze them in place.

We don't have tanks rumbling around or the Red Army to come "remove" them, but to keep my pickup truck or tractor from vanishing, gravel alone--at $400 delivered for 20 tons--won't do.  For the purposes of illustrating futility, I took a small scoop of "crusher run" gravel in my loader and spread it on the sea of mud.

 This will vanish quickly, as would a thin layer of larger #3 stone, purchased for roughly the same price. We are only a few miles from the quarry, and they know me well there. But before losing expensive stone deep in mud, an inexpensive road-bed needs to be established.

My technique is simple: toss in the free rubble I have, with flat sides up, break down larger chunks with a sledgehammer, then run the small tractor over it while doing chores. Here's the shot of the muddiest spot after a few passes:

With work, that will get smooth enough to hold a level bed of #3 gravel;  I will pay the boys at the quarry for 10 tons of that stone; placing it will be the subject of another post.

Timing is key here: if I wait until the dry summer we will likely have, the grass will be tall and the road dry. Setting stone now in late winter works beautifully to establish a road bed to last for many, many years.

I wish for a cohort of Legionaries under my orders, at times like this. Not to conquer the next county, but to get our pathways and roads sorted out. Every soldier carried tools that could make a road, and it was common practice to keep the legions employed doing public works for the Empire. It kept them busy and out of the sort of trouble that armed men, in groups, are likely to stir up.

Without such help, save for a fellow named John Deere, I get to work. Yet as the Romans would say, my practice is "festina lente." I make haste, slowly, before the weather warms, the snakes and the grass emerge, and the garden must go in. Thinking before doing will make a good road, as I am no Roman.

But how I love their roads and fashion sense.
