Byrom is the industrial and light-manufacturing corridor in southwest Tualatin, anchored along SW 124th Avenue and SW Tualatin-Sherwood Road. Asphalt paving in Byrom is industrial work, full stop -- the surface lots here support semi-truck inbound and outbound traffic, loading-dock approaches and aprons, forklift travel paths, employee surface lots, and truck-storage staging yards. The buyer is an industrial property owner, a logistics facility manager, or a corporate facilities lead for a manufacturing or distribution operation. The mix design, the base depth, the surface specification, and the scheduling all differ from retail or office paving in ways that change every line item on the bid. This guide covers the realistic scope and the vetting checklist for a Byrom paving job.
Why Byrom Paving Is Industrial Work, Not Commercial
The defining load on a Byrom lot is heavy-truck traffic -- typically Class-8 tractor-trailers with gross combined weight ratings up to 80,000 pounds (and in some cases, oversize-permit loads above that), running multiple inbound and outbound trips per day with concentrated wheel loading at the loading-dock approach and the gate area. A retail mix design built for passenger vehicles will fatigue under that load inside 3 to 5 years. Industrial paving for Byrom uses a different specification stack: a thicker asphalt section (typically 4 to 6 inches on the wear surface over 8 to 12 inches of compacted aggregate base), a binder grade selected for heavy-vehicle loading (PG 64-22 with a higher binder percentage than retail mix), and proof-roll testing of the subgrade before the base course goes down.
The loading-dock geometry adds its own constraint. Approach aprons need slope and cross-slope tolerances tight enough to keep semi-trailer dock-approach safe, and the apron surface specification often calls for concrete rather than asphalt at the highest-stress dock points, with asphalt running the approach and the staging yard around the concrete pads. The commercial asphalt paving in Tualatin page covers the broader Tualatin commercial reference; Byrom industrial work runs in the upper third because of the heavy-load specification.
The Three Byrom Paving Scopes
Most Byrom paving demand falls into three scopes. First, full lot mill-and-overlay or full-depth replacement on existing industrial parcels where the original 1980s-90s build-out has reached the end of its industrial service life. Second, new-construction paving on infill or expansion parcels where the civil drawings spec out the full industrial section from subgrade up. Third, targeted apron and dock-approach repair, where the loading-dock geometry has failed and the apron needs reconstruction rather than overlay.
The 24-hour operations scheduling matters across all three scopes. Many Byrom tenants run two- or three-shift operations with continuous inbound and outbound truck traffic, which means the paving schedule has to coordinate around production-shift changes, inbound-truck arrival windows, and the gate-staffing calendar. This is closer to airport-cargo or port-yard scheduling than to retail-strip-center scheduling.
Industry Cost Picture for Byrom Paving
The ranges below cover realistic Byrom industrial bid bands. Jobs with full-depth replacement, dock-approach reconstruction, or 24-hour operations coordination land in the upper third.
Industry Baseline Range
| Project Type | Cost Per Sq Ft | Typical Total |
|---|---|---|
| Industrial mill-and-overlay | $5 to $9 | $40,000 to $400,000+ |
| Full-depth industrial replacement | $10 to $18 | $80,000 to $800,000+ |
| Dock-approach reconstruction | $11 to $20+ | $25,000 to $150,000+ |
| Staging-yard new construction | $9 to $16 | $60,000 to $600,000+ |
| Truck-traffic apron (per sq ft) | $10 to $18 | $15,000 to $80,000+ |
| Subgrade proof-roll and remediation | $4 to $9 per sq ft | Bid as add-alt |
Current Market Reality
Byrom industrial paving bids regularly land in the upper band of the Washington County commercial reference for three reasons. First, the heavy-truck mix design and the thicker industrial section spec mean material cost per square foot runs 25 to 50 percent above a retail or office lot, with the binder grade premium accounting for a significant share. Second, 24-hour operations coordination is real overhead -- the contractor cannot stop production for the paving schedule, so the work has to thread through production-shift changes, inbound-truck windows, and gate scheduling, which adds 15 to 30 percent in labor and coordination time. Third, subgrade proof-rolling on industrial lots routinely reveals soft spots that need remediation before the base course goes down, and that remediation is rarely in the original scope. Cojo will not phone-quote a Byrom industrial lot -- the proof-roll, the production-coordination plan, and the dock-approach geometry have to be measured on site.

Permits, Industrial Zoning, and Coordination
The permit footprint for a Byrom paving job depends on three things. First, Washington County and City of Tualatin right-of-way permits for any work tying into SW 124th Avenue, SW Tualatin-Sherwood Road, or the adjacent industrial-zone streets. Second, the City of Tualatin's industrial-zone site-development review on any expansion or new-construction scope. Third, the tenant's internal safety and operations coordination matrix, which includes safety briefings for the paving crew, gate-access protocols, and production-shift coordination. Cojo runs the permit submittal and the production-coordination matrix in parallel with the bid.
For the follow-up striping scope -- forklift travel paths, semi-truck staging stall layouts, fire-lane re-striping intervals, and employee-lot ADA compliance -- the commercial striping in Tualatin page covers the parallel work.
How to Vet a Byrom Industrial Bidder
Three questions filter the bidder field. First, ask whether the bid includes a heavy-truck mix design specification (PG 64-22 binder grade or equivalent, with the binder percentage and aggregate gradation called out), or whether the mix is the contractor's standard retail spec. A bidder who hedges on the mix spec is selling a retail mix that will fatigue under industrial load. Second, ask whether subgrade proof-rolling and remediation is in the base bid or an add-alternate -- it should be the latter, with a clear unit price for any soft-spot remediation revealed during the proof-roll. Third, ask for a written production-coordination plan with named shift windows, inbound-truck access windows, and the safety-briefing protocol. A bidder who treats Byrom like retail is the wrong contractor for this corridor.
Maintenance and Long-Term Planning
Once the new lift is down, asphalt maintenance on a 18- to 30-month sealcoat rotation (shorter than retail because of heavy-truck wear) is what protects the industrial capital investment against the rest of its service life. The Tualatin asphalt paving services page covers the broader Cojo Tualatin scope. Ready to price a Byrom industrial lot, an apron rebuild, or a staging-yard new construction? Schedule a site walk and Cojo will proof-roll the subgrade, scope the production coordination, and write a number that survives the industrial load.
