Speed Hump Maintenance: 2026 Inspection & Repair Guide

A well-built asphalt speed hump runs 7 to 10 years on a parking lot, and 5 to 7 on a residential street, before it needs more than a paint refresh. A rubber hump bolted to asphalt usually goes 5 to 8 years before bolts loosen or rubber sections fatigue. Maintenance is what decides whether you hit the top of those ranges or replace it early. Below: our annual inspection checklist, the repair triggers that buy more service life, and where the replace-versus-repair line falls.

What does speed hump maintenance actually cover?

The four maintenance categories are paint and reflectivity, structural integrity, hardware (rubber humps), and signage. The Federal Highway Administration's Traffic Calming ePrimer treats all four as part of the calming-device lifecycle, not optional add-ons.

How often should speed humps be inspected?

Cojo's standard cadence:

• Quarterly -- visual walk-around. 5 to 10 minutes per hump. Check paint visibility, edge cracking, hardware tightness on rubber humps, and warning-sign condition.
• Annually -- full inspection. Measure profile height (a degraded hump can lose half an inch of crown over 5 years), photograph the patch boundary, log every crack longer than 6 inches.
• After every freeze-thaw winter -- post-thaw inspection. Oregon's wet winters drive most asphalt-hump degradation. The FHWA pavement preservation guidance flags spring as the highest-yield inspection window.

Quarterly Inspection Checklist

Use this as the field card. A property manager or maintenance lead can run it in under 10 minutes per hump.

Item	Pass criteria	Action if fail
Yellow chevron paint visible	Reflective at 100ft at night	Re-paint within 30 days
Edge cracking	None longer than 12 inches	Crack-fill
Surface raveling (loose aggregate)	None	Schedule slurry seal or fog seal
Profile height	3 to 4 inches at crown	Re-pave or replace if below 2.5 inches
Patch boundary	No water ponding	Re-grade or re-patch
Reflective markers	All present, lit by headlights	Replace missing or dim units
MUTCD W17-1 warning sign	Legible at 100ft, post plumb	Re-sheet or straighten post
Advance pavement marking (HUMP text)	Visible from approach	Re-paint with thermoplastic
Rubber hump bolts	Torque to 30 to 40 ft-lbs	Re-torque or replace anchors
Rubber hump section seams	No vertical lift between sections	Re-anchor or replace section

Annual Inspection Checklist

The annual pass extends the quarterly checklist with measurement and documentation.

Profile measurement

Place a 10-foot straightedge across the hump perpendicular to traffic. Measure peak height with a tape. Compare against the original install spec (typically 3 to 4 inches per ITE Traffic Calming Manual recommendations). If the hump has lost more than half an inch of crown, the calming effect drops measurably -- replacement is more cost-effective than chasing partial repaves.

Photo documentation

Photograph the hump from both approaches and from above (a phone on a selfie stick works). Date-stamp the photos. After 3 years of annuals you have a degradation timeline that justifies the replacement budget request.

Crack-fill log

Log every crack longer than 6 inches by location. Cracks under a quarter inch wide can be sealed with hot-pour rubberized sealant. Cracks wider than half an inch are structural and indicate base-course failure -- those need a saw-cut and patch, not just sealant. The FHWA Crack Sealing Manual is the reference Cojo crews work from.

What are the most common speed hump failures?

Cojo's repair call log breaks roughly 70/20/10:

1. Faded paint and reflectivity loss (about 70 percent of calls). The hump itself is fine; the visibility is gone.
2. Edge cracking and shoulder spalling (about 20 percent). Asphalt humps fail at the edges first because the tapered transition is the thinnest section.
3. Profile loss or full structural failure (about 10 percent). Usually traceable to under-spec base prep at install.

How do you fix faded speed hump paint?

Re-paint when reflectivity drops below 100 mcd/m^2/lux as measured by a retroreflectometer, or when night-time visibility from 100 feet is no longer obvious. Cojo crews refresh the yellow-and-black chevron pattern every 18 to 24 months on water-based traffic paint, or every 4 to 5 years on thermoplastic. Thermoplastic is the better long-term spend even though the upfront cost is 2.5 times higher.

How do you fix edge cracking on a speed hump?

Cracks under a quarter inch wide get a hot-pour rubberized sealant, applied with a melt-and-pour pot. Cracks wider than half an inch get a saw-cut, partial mill, and hot-mix patch -- the same process as the removal patch step but limited to the failed area. The Oregon DOT Section 00744 tack-coat and patch spec applies.

When should a speed hump be replaced rather than repaired?

Replace when any of the following are true:

• Profile height is below 2.5 inches at the crown
• Edge cracking covers more than 30 percent of the hump's perimeter
• Multiple unsuccessful patches have already been performed
• The hump's location no longer matches current traffic patterns (lane re-stripe, new emergency-access requirement)
• A code change requires a different device (cushion for fire access, table for bus routes)

Lifespan Benchmarks by Material

Material	Typical lifespan (parking lot)	Typical lifespan (residential street)
Asphalt speed hump	7 to 10 years	5 to 7 years
Rubber speed hump (modular)	5 to 8 years	4 to 6 years
Plastic speed hump	3 to 5 years	2 to 4 years
Concrete speed hump (cast-in-place)	12 to 20 years	10 to 15 years

These are Cojo field observations consistent with the ITE Traffic Calming Manual lifecycle guidance. Bend's freeze-thaw climate runs every category 1 to 2 years short.

How Much Does Speed Hump Maintenance Cost?

Industry Baseline Range

Maintenance task	Range
Annual inspection (per site, up to 5 humps)	$200 to $500+
Re-paint chevrons (water-based, per hump)	$80 to $180+
Re-paint chevrons (thermoplastic, per hump)	$250 to $500+
Crack-fill (per linear foot of crack)	$4 to $9+
Edge patch (small, single hump)	$400 to $1,200+
Bolt re-torque (rubber hump, per unit)	$80 to $150+
Reflective marker replacement (per marker)	$25 to $60+
Warning sign re-sheet (MUTCD W17-1)	$120 to $250+
Full hump replacement	$2,000 to $5,000+

These figures reflect published industry averages. Current market pricing varies significantly and actual quotes may fall well outside these ranges based on site-specific conditions, material costs, and project complexity.

Current Market Reality

Oregon's 2026 traffic-paint and labor pricing has pushed re-paint costs about 12 to 18 percent above the 2024 baseline. Multi-hump bundling on the same site typically drops the per-hump price by 25 to 35 percent because mobilization is amortized.

Cojo's Salem Maintenance Walk-Through

In April 2026 Cojo inspected an apartment complex in South Salem with 6 asphalt humps installed in 2019. The annual pass found 4 humps with worn chevrons, 2 humps with edge cracking, and 1 hump with a 1.5-inch crown loss (down from 3 inches at install). The crew re-painted all 6 with thermoplastic, sealed 38 linear feet of cracking, and replaced the 1 failing hump in a single 2-day mobilization. Total cost was significantly lower than the budget the owner had set aside for full replacement of all 6.

Build Maintenance into the Property Budget

The cheapest hump is the one that lasts 10 years instead of 5. A $400 annual inspection and a $200 re-paint every 2 years protects a $3,000 install -- a 10x return on the maintenance dollar. Cojo offers an annual maintenance contract for property managers that bundles inspections, paint refreshes, and crack-fill into a single line item. See asphalt maintenance services for the full scope, or browse the speed hump installation in Salem page for local maintenance and replacement examples.
