Field GuideProximity warning and struck-by safety technology field guide for paving crewsWorker tags, cameras, and radar reduce the struck-by risk around heavy equipment, but they are the last layer.

Paving calculators

Aggregate base calculatorFind the tons of crushed aggregate base for a given area and compacted depth.Asphalt density calculatorTurn a mat density reading and the Gmm into % Gmm and air voids, and check it against the acceptance target before the lot cools.Asphalt tonnage calculatorEstimate the tons of hot-mix asphalt for a job from length, width, compacted thickness, and the mix unit weight, with a waste allowance.Soil swell/shrink calculatorConvert earthwork volume between bank, loose (haul), and compacted using swell and shrink: loose = bank x (1+swell), compacted = bank x (1-shrink).Trench volume calculatorFind excavation volume: length x width x depth in feet, divided by 27 for cubic yards, plus an approximate truck-load count.

Paving readiness checks

ADA ramp and parking readinessA two-minute pass that flags the slope, count, aisle, warning, and sign gaps that get accessible work chipped out and re-poured.Density acceptance readinessA 2-minute check that catches the missing Rice test, uncorrelated gauge, or untested joint before the cores come back and settle it for you.Milling grade-control readinessA two-minute check on whether depth, grade reference, drum, castings, and the drop-off are handled before the drum drops.Asphalt paving day readinessA 2 minute check before the paver moves, so a short compaction window, a cold joint, or a segregated mat does not lock low density into the lot.Pavement foundation readinessA quick check on subgrade and base, because the layer under the pavement decides how long the surface lasts, and it is buried after you pave.Striping readiness checkA 2-minute check that catches the prep, cure, weather, layout, and record gaps that peel a lot or fail its inspection.Pavement preservation timingA quick check on treatment selection and timing, so preservation dollars go to roads that can still be saved instead of ones that need reconstruction.Struck-by prevention readinessA 2 minute check on whether your site separates people from equipment, with the plan, the spotters, and the tech to back it up, before a struck-by injury.
