Bumps and Stops
Amarillo Pavement Pros: Speed Bumps, Wheel Stops and Bollards in Amarillo, TX
Amarillo Pavement Pros connects commercial property owners in Amarillo, TX with local pavement contractors, and this page covers bumps and stops across Potter County and Randall County and the wider Texas Panhandle.
Small hardware that decides how a lot behaves
Speed bumps, wheel stops, bollards and signage are the least expensive items on a commercial parking lot and they have a disproportionate effect on how it gets used and how long the pavement lasts.
Traffic that moves too fast through a lot wears the surface harder, particularly at turns where speed translates into shear. Vehicles that overrun stalls damage landscaping, curbs and building fabric. Unprotected utilities and storefronts get hit. None of that is dramatic individually, and collectively it is a steady drain on a property.
Speed control that suits the traffic
The choice between a bump and a hump is about what has to get through.
A speed bump is short and abrupt. It brings vehicles almost to a stop and it is appropriate where that is genuinely wanted, such as immediately before a pedestrian crossing point or at a blind corner.
A speed hump is longer and gentler, slowing traffic to a moderate speed rather than stopping it. On a property where fire apparatus, delivery trucks or refuse vehicles circulate, humps are usually the better answer, because an abrupt bump taken by a loaded vehicle is hard on the vehicle and hard on the pavement at the bump.
Placement matters more than the device. A bump immediately after an entrance catches drivers before they have accelerated. Bumps spaced too far apart simply produce a cycle of acceleration and braking, which puts more stress into the pavement than a steady speed would.
Material is the second decision. Asphalt bumps are formed into the pavement and are permanent. Rubber units bolt down and can be relocated, which suits a lot whose layout may change, and they cope with thermal movement without cracking. In a climate running about 85 freeze-thaw cycles a year, that last point is not trivial.
Wheel stops, and why they usually fail at the fixings
A wheel stop’s job is to keep a vehicle from overrunning its stall into landscaping, a walkway, a building face or the vehicle in the row opposite.
Concrete stops are the traditional choice and they suffer here. Concrete takes water into its surface pores, and freeze-thaw cycling spalls flakes off it. Add repeated impact from bumpers and a concrete stop in this climate becomes a crumbling obstacle within a few years. Recycled rubber and plastic units deal with both impact and thermal cycling considerably better.
Whatever the material, most wheel stop failures are actually fixing failures. A unit that has worked loose from its pins or anchors is a movable object in a parking stall, which is worse than no wheel stop at all. Anchoring into sound pavement, and checking existing stops when a lot is being restriped anyway, is the practical answer.
Placement deserves a moment of thought where accessible parking is involved. An access aisle beside an accessible space has to remain clear and usable, and a wheel stop set so that it intrudes into that aisle or obstructs the route toward the entrance defeats the purpose of the aisle.
Bollards where impact is foreseeable
Bollards protect things that are expensive or dangerous to hit.
The usual candidates on a commercial property are gas meters and risers, utility cabinets, fire department connections, building corners exposed to a drive aisle, storefront glazing facing a parking row, and equipment left in circulation areas.
The important distinction is between a bollard that is decorative and one that will actually stop a vehicle. A surface-mounted sleeve looks the same from ten feet away and will not resist a real impact. Where the point is protection rather than delineation, the bollard needs proper embedment into the ground, which means coring or excavating the pavement and setting it in concrete.
Questions we get asked
What is the difference between a speed bump and a speed hump?
A speed bump is short and abrupt, and it forces vehicles to a crawl. A speed hump is longer and gentler, and it slows traffic to a moderate speed without stopping it. Lots where emergency or delivery vehicles need to circulate usually want humps rather than bumps, since an abrupt bump is hard on a loaded truck.
Are rubber or asphalt speed bumps better?
They suit different situations. Asphalt bumps are formed as part of the pavement, last well and cannot be removed casually. Rubber bumps bolt down, can be relocated or taken up, and suit a lot where the layout may change. Rubber units also handle the thermal movement here without cracking, which asphalt bumps sometimes do.
How long do wheel stops last?
It depends heavily on the material. Concrete wheel stops chip and spall under repeated impact and freeze-thaw, and Amarillo runs about 85 freeze-thaw cycles a year. Recycled rubber and plastic units resist that better and tend to survive being struck. Either way the fixings matter as much as the unit, since most failures are a stop that has worked loose rather than one that has broken.
Where are bollards actually needed?
Anywhere a vehicle could reach something that should not be hit. Building corners at drive aisles, utility meters and gas risers, storefront glass facing a parking row, fire department connections, and equipment cabinets are the usual candidates. A bollard that is going to take a real impact needs to be properly embedded rather than surface mounted.
Do wheel stops interfere with accessible parking?
They can, and it is worth checking. A wheel stop placed so that it intrudes into an access aisle, or so that it obstructs the route from the space to the accessible route, creates a problem. The access aisle beside an accessible space has to stay clear and usable.
Can this be combined with striping work?
It normally should be. Most of the cost of a small job is mobilisation, so fitting stops, bumps, bollards and signage during a striping visit costs substantially less than arranging each separately.
