A 12-foot Watts profile asphalt speed hump (the residential default) costs $1,500 to $4,500 installed for a single unit on private property in Oregon's I-5 corridor in 2026. Material runs $400 to $1,200 of the total; labor runs $900 to $3,200. The 14-foot Seminole and sinusoidal profiles add 15 to 25%, and the 22-foot speed table runs 3 to 4 times the cost. Asphalt's lifecycle wins on cost-per-year ($80 to $330 annualized over 15 to 25 year lifespan) versus rubber's $250 to $900.
Industry Baseline Range
| Component | Single Unit | Multi-Unit (3+) |
|---|---|---|
| Hot-mix asphalt material | $400 to $1,200 | $300 to $900 |
| Labor (crew + traffic control) | $900 to $3,200 | $600 to $2,200 |
| Pavement marking + signage | $200 to $600 | $150 to $450 |
| Installed total per unit (12 ft Watts) | $1,500 to $5,000 | $1,050 to $3,550 |
Current market reality
Asphalt-hump pricing in 2026 reflects roughly 18% increases in hot-mix prices over 2024 to 2025 (per RSMeans regional data) plus tight traffic-control labor in Oregon's I-5 corridor (rates 12 to 20% above 2023). The midpoint of the industry baseline still applies, but jobs at the upper end of the range are more frequent in 2026 than in prior years. Cities and HOAs that budgeted in 2023 for a 2026 install often need a 15 to 20% budget increase to land the project at current rates.
What does the material line cover?
A 12-foot Watts profile speed hump consumes roughly 1.3 cubic yards of compacted hot-mix asphalt. The material line covers:
- Hot-mix asphalt: $300 to $900 for delivered hot-mix at $90 to $130 per ton in 2026 Oregon I-5 corridor pricing.
- Tack coat: $30 to $80 for the binder applied between existing pavement and the new hump material.
- Edge taper material: $50 to $200 for the smooth pavement transition at the leading and trailing edges.
- Mobilization adder: $20 to $80 if the asphalt plant is far from the site.
Larger profiles consume more material proportionally. A 14-foot Seminole profile uses 1.5 cubic yards (15% more); a 22-foot speed table uses 2.4 cubic yards (85% more).
What does the labor line cover?
Labor breaks into four scopes for a single-unit install:
- Layout, prep, and pour: 90 to 180 minutes for a 3-person crew. Layout with chalk, mill the existing asphalt approach 1 inch, place hot-mix in 1.5-inch lifts.
- Compaction: 30 to 60 minutes with a 1- to 3-ton vibratory roller.
- Traffic control: 60 to 240 minutes for setup, runtime, and teardown per MUTCD Part 6.
- Pavement marking: 30 to 90 minutes for chevron paint and W17-1 sign installation.
Total crew time: 4 to 6 hours per unit. Hourly crew rates run $80 to $130 per person in 2026 Oregon, with traffic-control labor at $45 to $85 per hour. For full labor detail, see speed hump installation cost.
How does the asphalt price compare nationally?
Oregon I-5 corridor hot-mix prices in 2026 sit at $90 to $130 per ton (RSMeans regional data) versus the U.S. average of $80 to $115 per ton. The Pacific Northwest premium reflects:
- Limited number of regional asphalt plants
- Higher fuel costs (Oregon ranks above U.S. average for fuel per gallon)
- Stricter binder grade requirements for freeze-thaw climates
Cities outside the I-5 corridor (Bend, Klamath Falls, Eastern Oregon) sometimes pay more due to longer trucking distances from regional plants.
How does multi-unit pricing work?
Multi-unit installs (3+ humps on the same street) save 15 to 25% on per-unit cost. Three savings drivers:
- Mobilization spreads across more units. A $400 mobilization fee divided across 4 humps drops to $100 per unit.
- Hot-mix delivery consolidates. A 4-hump project orders a single 6-ton truck (typical $700 minimum) versus four single-unit deliveries paying minimum truck fees four times.
- Traffic control runs continuously across the project rather than per-unit.
In a March 2026 install on a Lake Oswego greenway (3 humps in 940 ft), our crew came in at $2,400 per unit installed versus $3,200 per unit for a comparable single-unit job. The 25% savings was material-driven (single delivery for 4 cubic yards) plus traffic-control consolidation.
What is the lifecycle cost?
Asphalt's 15 to 25 year lifespan delivers strong cost-per-year math:
| Profile | Installed Cost | Lifespan | Annualized Cost |
|---|---|---|---|
| 12 ft Watts | $1,500 to $4,500 | 15 to 25 years | $80 to $330/year |
| 14 ft Seminole | $1,800 to $5,000 | 15 to 25 years | $90 to $360/year |
| 14 ft sinusoidal | $1,800 to $5,500 | 15 to 25 years | $90 to $400/year |
| 22 ft flat-top | $5,000 to $15,000 | 15 to 25 years | $250 to $1,100/year |
The annualized math favors asphalt strongly versus rubber. For lifecycle comparisons, see rubber speed hump vs asphalt.
Frequently asked questions
How much does an asphalt speed hump cost in Oregon? $1,500 to $4,500 installed for a single 12-foot Watts profile on private property in 2026. City-contracted work with prevailing wage adds 25 to 35% to labor lines.
Does the cost include the warning sign and chevron paint? Most quotes include both. The W17-1 sign and yellow chevron pavement marking are standard inclusions in residential speed-hump bids.
Why is asphalt cheaper than concrete for speed humps? Asphalt material costs less per cubic yard ($90 to $130 per ton versus $200 to $300 per cubic yard for concrete), and labor is faster (no concrete cure time, no formwork). Concrete humps are rare in U.S. residential traffic-calming work.
Can a speed hump be installed on an existing asphalt overlay? Yes, if the overlay is at least 1 inch thick and structurally sound. The hump material bonds to the existing surface via tack coat. Thinner overlays may require milling first.
How much does it cost to remove an asphalt speed hump? $1,500 to $3,000 for saw-cut, grind, patch, and surface restoration. Removal cost is roughly 60 to 80% of install cost.
