Speed hump installation labor (excluding material) runs $900 to $3,200 per unit for an asphalt Watts profile on private property in Oregon's I-5 corridor in 2026. The labor line covers a 3-person crew for 4 to 6 hours, traffic control with cones and signage, paving roller and screed equipment, and post-pour pavement marking. On city-contracted work where prevailing wage applies, the same labor scope runs $1,200 to $4,400 per unit. Multi-unit projects share mobilization, traffic control, and crew time across more devices, dropping the per-unit labor allocation 15 to 25%.
Industry Baseline Range
| Labor Component | Single Unit | Multi-Unit (3+) |
|---|---|---|
| Crew time (3-person, 4 to 6 hr) | $500 to $1,800 | $350 to $1,200 |
| Traffic control setup and runtime | $200 to $700 | $130 to $450 |
| Equipment (roller, screed, paint) | $100 to $400 | $80 to $300 |
| Pavement marking labor | $100 to $300 | $70 to $200 |
| Labor total per unit | $900 to $3,200 | $630 to $2,150 |
Current market reality
Labor costs in 2026 sit at the upper end of historical baselines because traffic-control labor stays tight in Oregon's I-5 corridor (hourly rates 12 to 20% above 2023 levels) and skilled paving-crew availability has been compressed by simultaneous demand from city pavement-management programs and private commercial work. Most quoted jobs come in at the median or upper-third of the range; the lower end applies mainly to multi-unit projects with low-complexity sites.
What does the labor line cover?
Four scopes:
- Layout, prep, and pour. Crew lays out hump centerline with chalk, mills the asphalt approach if needed, places hot-mix in 1.5-inch lifts, and screeds the parabolic profile by hand.
- Compaction. A 1- to 3-ton vibratory roller passes over the screeded asphalt to lock the profile and bring density to spec.
- Traffic control. Cone deployment, sign placement, and flagger labor for 4 to 6 hours per single-unit install.
- Pavement marking. Yellow chevron paint pattern on the leading face plus the W17-1 advance warning sign installed 100 to 200 ft upstream.

How does crew size affect cost?
A 3-person crew is the residential default. Smaller 2-person crews work for rubber-hump installs (no asphalt screeding required) but slow down asphalt installs to the point that the labor savings disappear. Larger 4 to 5-person crews speed up multi-unit projects.
In a 2025 install for a Beaverton HOA (4 humps on a 600-foot loop), our crew used a 4-person team to compress the project to a single 9-hour day instead of two 6-hour days. The labor cost rose by one person's wages but fell on traffic-control runtime and mobilization fees, netting to a 15% savings versus the 2-day baseline.
What is traffic control and why does it cost this much?
Traffic control is the temporary lane closure, signage, and flagger labor that keeps the work zone safe. The Manual on Uniform Traffic Control Devices (MUTCD) Part 6 governs work-zone setup; Oregon DOT's Traffic Manual provides state-level standards.
A typical residential speed-hump traffic-control setup includes:
- 6 to 12 traffic cones
- 2 advance warning signs (W20-1 "ROAD WORK AHEAD" and W21-1 "WORKERS AHEAD")
- 2 lane-shift signs (W4-1 "MERGE")
- 1 flagger station with stop/slow paddle
- 1 BACA (barrier and attenuation) plan if work is on a collector with 30+ mph posted
Labor for setup, runtime, and breakdown runs 2 to 4 hours per single-unit job. Hourly traffic-control labor runs $45 to $85 in 2026 in Oregon.
What is the difference between private and city-contracted labor cost?
City-contracted work in Oregon uses prevailing wage per ORS 279C (Oregon BOLI Prevailing Wage). Prevailing wage adds 25 to 35% to labor lines compared to private-property installs.
A typical breakdown:
| Scenario | Labor Cost (per unit) |
|---|---|
| Private HOA / commercial property | $900 to $3,200 |
| City-contracted (prevailing wage) | $1,200 to $4,400 |
How does mobilization affect the labor line?
Mobilization is the cost of bringing the crew, equipment, and materials to the site. For a single-unit speed hump install, mobilization typically runs $250 to $700 and is bundled into the labor line. Multi-unit projects spread mobilization across the unit count; a 4-hump project effectively pays one mobilization fee.
If your site is more than 30 miles from the contractor's base of operations, expect a per-mile mobilization adder. Most Oregon contractors charge $1.50 to $2.50 per mile each way beyond the standard service radius.
How long does the install take?
A single-unit asphalt speed hump install runs 4 to 6 hours from setup to teardown. The breakdown:
- Setup, layout, traffic control deployment: 60 to 90 minutes
- Mill and prep: 30 to 60 minutes
- Pour, screed, compact: 90 to 120 minutes
- Cure (light cure for marking): 60 to 90 minutes
- Pavement marking and signage: 60 to 90 minutes
- Traffic-control breakdown: 30 minutes
Multi-unit projects compress the per-unit time as the crew develops rhythm; a 4-hump project typically runs 9 to 12 hours total versus 4 x 5 = 20 hours of additive single-unit time.
Frequently asked questions
How much does it cost to install a speed hump? Labor only runs $900 to $3,200 per unit for a private-property install in Oregon's I-5 corridor in 2026. With material and signage, the all-in installed cost runs $1,500 to $5,000.
Can I install a speed hump myself? Asphalt humps require professional paving equipment (screed, roller) and are not realistic DIY projects. Modular rubber humps can be self-installed with concrete anchors and a torque wrench, but professional install ensures correct anchor pattern and pavement marking compliance.
Why is traffic control so expensive? MUTCD Part 6 mandates specific signage, cone spacing, and flagger labor for work zones. Oregon DOT's Traffic Manual reinforces these standards. Skilled flaggers and certified traffic-control supervisors are tight in 2026 labor markets, pushing rates up.
Does the labor cost include warranty? Most contractors warrant the install for 1 year against workmanship defects (separation from substrate, profile failure, anchor failure on rubber). Material warranties on asphalt are typically 5 years; on rubber, 3 to 7 years.
What is the labor cost difference between asphalt and rubber humps? Rubber installs are 30 to 50% lower on labor (no asphalt screeding, no roller, faster crew). The labor savings narrow the cost gap with asphalt's higher material cost; the all-in installed cost is similar.
