Installing a rubber speed bump on existing pavement runs 60 to 90 minutes per bump for a 1 to 2-person crew. You need a hammer drill, anchor hardware matched to the substrate, and a torque wrench. The procedure breaks into 6 steps. Rubber installs faster than asphalt-poured bumps because the section is pre-formed and shows up at the site ready to anchor — no mill, no pour, no cure cycle. The ITE Traffic Calming Manual treats rubber as the most common modular bump material for parking lots.
Below: the full procedure, the tool and hardware spec, OSHA safety requirements, and where Oregon code factors in.
What Makes Rubber Speed Bump Install Different from Asphalt?
Three things separate rubber from asphalt installs:
- No paving crew. Rubber bumps need a 1 to 2-person crew with hand tools, not a paving crew with hot-mix and a screed.
- No cure time. Rubber bumps open to traffic the moment chevron paint dries. Asphalt bumps need 24 to 72 hours.
- Removable. Rubber bumps unbolt for snow removal, restriping, or seasonal storage. Asphalt is permanent.
The trade-off is lifespan: rubber typically runs 3 to 5 years in Oregon's freeze-thaw climate per Cojo field experience and ITE references; asphalt typically runs 7 to 10 years.
What Tools and Hardware Do You Need?
- Rubber speed bump section (4 ft, 6 ft, or 10 ft sized to lane width)
- Hammer drill with 3/8-inch masonry bit (concrete substrate) or spike-driver (asphalt substrate)
- Anchor hardware kit — concrete sleeve anchors with epoxy OR asphalt spike anchors with hot-pour
- Epoxy gun and two-part epoxy (concrete substrate only)
- Torque wrench to manufacturer spec, typically 25 to 50 ft-lb for rubber bumps
- Chalk line and speed square for layout
- Tape measure (25 ft minimum)
- Yellow and black traffic paint for chevron per MUTCD (mutcd.fhwa.dot.gov)
- Reflective end caps (paired)
- W17-1 advance warning sign and post for upstream installation
- Personal protective equipment: ANSI Z87.1 safety glasses, gloves, high-visibility vest, hard hat per OSHA
Total tool cost for first-time DIY installers runs $150 to $400 if drill and torque wrench are not already on hand.
What Are the 6 Steps to Install a Rubber Speed Bump?
Step 1 — Position the Bump
Place the rubber bump section on the pavement perpendicular to the direction of travel. The bump must span the full lane width per ITE Traffic Calming Manual guidance to prevent drivers from steering around. For 22-foot two-way drive aisles, link two 10-foot sections plus a 2-foot mid-section using manufacturer-supplied connectors.
Step 2 — Mark Anchor Holes
The rubber section comes with pre-drilled anchor holes on a fixed pattern. Use a piece of chalk to mark each hole position through the bump onto the pavement. Most 10-foot sections carry 6 anchor holes; heavy-duty sections carry 8. Remove the bump and verify each marked spot is at least 4 inches from a pavement crack or edge.
Step 3 — Drill the Anchor Holes
Use the hammer drill with the masonry bit. For concrete substrate, drill 3/8-inch holes 2.5 to 3 inches deep — match the spec on the anchor sleeve packaging. For asphalt substrate, drive spike anchors directly using the spike-driver to manufacturer-specified depth (typically 4 to 6 inches). Vacuum or blow concrete dust from each hole before moving on.
Step 4 — Insert Anchors and Apply Epoxy
For concrete substrate, inject two-part epoxy into each hole to roughly 75 percent depth. Insert the concrete sleeve anchor immediately. Excess epoxy will displace as the anchor seats — wipe clean. For asphalt substrate, spike anchors are already set from Step 3 and require no epoxy.
Step 5 — Bolt Down the Speed Bump
Lift the rubber section back into position over the anchor pattern. Lower it onto the anchors so pre-drilled holes align with anchor heads. Hand-thread bolts into each anchor first; do not torque yet. Once all bolts are hand-tight, use the torque wrench in a star pattern (alternating across the bump, not end-to-end) to tighten to manufacturer spec — typically 25 to 50 ft-lb. Over-torquing strips concrete sleeves; under-torquing allows the bump to lift under traffic.
Step 6 — Install Reflectors and Chevron Paint
Apply reflective end caps to each lane-edge end of the bump. Most commercial installs add reflective tape strips along the chevron-painted top surface for double-redundant nighttime visibility. Paint the yellow-and-black chevron pattern per MUTCD guidance — 6-inch alternating stripes at 45 degrees. Allow 30 to 60 minutes cure time on the chevron paint before opening to traffic. Install the W17-1 advance warning sign 100 to 200 feet upstream per FHWA spacing guidance.
How Long Does Installation Actually Take?
| Site Condition | Time per Bump | Crew |
|---|---|---|
| Existing concrete pavement, no traffic control | 60 to 90 min | 1 to 2 |
| Existing asphalt pavement, no traffic control | 50 to 80 min | 1 to 2 |
| Existing pavement, with traffic control | 90 to 150 min | 2 to 3 |
| Multi-bump commercial install (4 bumps, 1 day) | 6 to 10 hours total | 3 to 4 |
What Are the Most Common Mistakes?
Three mistakes account for most rubber-bump install failures:
- Anchor holes drilled at an angle. A canted hole leaves the anchor sleeve cocked, which fails under traffic. Hold the drill perpendicular to the pavement.
- Bolts torqued before all are hand-tight. Star-pattern torquing only works if all bolts are seated first. Torquing one bolt fully before threading the rest pulls the bump out of square.
- Chevron paint applied to wet or cold pavement. Traffic paint requires pavement above 50 degrees F and dry surface. Cold or wet conditions cause paint failure within weeks.
On a 14,000-square-foot Salem retail center we restriped in March 2026, we replaced four rubber speed bumps installed in late 2023. Two had failed at the anchor points — bolts had been hand-tightened rather than torqued. Replacement and re-anchor took our crew about 6 hours total. Proper torque at install would have prevented the failure.
When Should You Hire a Contractor Instead?
Hire a contractor when:
- The site needs MUTCD-compliant signage and chevron paint that must pass jurisdiction inspection
- More than 4 bumps are scoped (mobilization and crew time savings on multi-bump installs)
- The site requires Oregon prevailing-wage labor (most public-works and certain commercial projects per Oregon BOLI, oregon.gov/boli)
- Traffic control exceeds basic cone placement
- The substrate is unfamiliar (mixed asphalt-over-concrete, ADA pathway proximity, etc.)

Or Hire Cojo's Installation Crew
Rubber bumps install fast when done right and fail fast when done wrong. Cojo installs commercial rubber speed bumps across the Oregon I-5 corridor with itemized quotes, torque-spec records, and prevailing-wage compliance where required. Hire Cojo's installation crew for your next project.
