What happens here

The project begins with a prepped area that has already had its sub-base excavated and an initial layer of Class 5 aggregate laid and compacted. The primary goal of this initial step is to ensure the Class 5 base layer is at the correct elevation, 3 inches below the final string line (which represents the top of the pavers). If the base is too high, additional material needs to be removed using a skid-steer loader and shovels. If it's too low, more Class 5 aggregate must be added and then raked and leveled using a landscaping rake and shovel. The Class 5 aggregate is compacted in lifts (sections) using a plate compactor.

Goal: Achieve the correct elevation and compaction for the Class 5 aggregate base.

Tools and materials

Hand Tamper — Fine-tuning compaction in smaller or harder-to-reach areas
Landscaping Rake — Leveling and distributing Class 5 aggregate
Plate Compactor Northstar — Compacting the Class 5 aggregate base in uniform lifts
Shovel — Removing or spreading Class 5 aggregate
Skid-Steer Loader Caterpillar — Moving and spreading large quantities of Class 5 aggregate
String Line — Establishing the target height for the paver surface and, by extension, the base layers
Class 5 Aggregate — Creating the load-bearing base layer of the driveway

parking so let's just dive right into it we need to be the class five needs to be three inches below that spring line we need sand and then our flops so we just ran one measured we're only about an inch less in some spaces so we have to scrape down another two inches of this class five to get it where it needs to be Sam and Blaine are prepping the class-five bass the next step will be Sam but before we do that we're gonna run through all of the depths and measurements of the different materials that we've put in place before the pavers get installed they touch up the site before they take their first set of measurements that's probably pretty close that string line represents the top of the pavers from there everything gets measured down and bass ackwards will show you exactly what we mean we're about three and a half inches down here so let's run through these numbers real quick the pavers themselves are two and three eighths inches thick we've got to allocate for one inch of sand then we've made our sub cut 12 inches below the top of the pavers so the rest of that means its class five base material in this case that's 8 and 5/8 inches thick boys add a little class 5 in places and take a little bit away they want to get this perfect because the depth of the class vibe determines the depth of the sand you don't want any more than one inch of sand anywhere beneath the paver project [Music] this base material is eight inches thick and has been packed into two lifts at four inches each any higher bow spots on the classify base get worked out so that they don't impact the depth of the sand that comes next what do you think about
