What Are the Standard Dimensions of a Parking Space?

One of the more important decisions for a commercial space is the design of the parking lot. These lots should be safe to drive in, comfortable for customers to use, and compliant with regulations. However, there are no one-size-fits-all parking space dimensions in Colorado. The spaces vary depending on a number of factors, from curb angle to traffic and more.

First and most importantly, it’s critical to check your local regulations. These vary noticeably from one town or county to the next. Errors here, particularly for handicap accessible parking spaces, can result in hefty fines. Business owners may also face the cost and inconvenience of having to re-plan and re-paint the lot. A little due diligence can save you in the long run.

With that being said, here are some general guidelines to use as a starting point for parking lot planning:

Curb Angle

One critical factor to parking space size is the angle that the space is set to the curb. In most areas of Colorado, this angle will affect the space length and sometimes the width. For example, in Glendale a 45 degree parking stall must be 8’6” wide and project 17’4” from the curb. Increase that to 60 degrees and the stall must be 8’6” wide and project out by 18’10”.

Traffic patterns

A two-way drive aisle clearly needs to be wider than an aisle that only has one way traffic. However, they aren’t necessarily twice as wide. For instance, in Denver a parking aisle is a minimum of 13 feet wide for one way traffic and 20 feet wide for two-way traffic when the spaces are angled at zero degrees. If the spaces are set at 90 degrees, the parking aisle must be a minimum of 23 feet for both one way and two-way traffic.

Type of Parking Lot

In some areas such as Grand County, parking space sizes may vary depending on the kind of parking structure. Typical spaces in open areas may be 10 by 20 feet. Meanwhile, a covered or underground lot can reduce that to 9 by 18 feet.

Type of Vehicle

Certain areas allow smaller commercial parking spaces designated for compact cars only. In Denver, a standard parking space at 60 degrees might be 8.5 feet wide by 17.5 feet long. Meanwhile, a compact space of 60 degrees shaves that down to 7.5 wide by 15.5 long.

Bicycles and Parking Lots

Your business’s parking lot may be required to provide racks for a certain number of bicycles per parking spaces. For instance, in Glendale a parking lot with 50 or more spaces must provide racks for 1 bicycle per 20 spaces, rounding up. In other areas like Lakewood, bicycle spaces are mandated by the business’s square feet.

Handicap Accessibility

Handicap accessible parking spaces are subject to a wide variety of local and national regulations. Again, this is well worth your time to research. In general, these parking stalls are placed next to the front doors or handicap accessible ramp. One important factor to consider during planning is the access aisle. This space (in Glendale, it is 5 feet wide) allows unobstructed access for wheelchair users to enter and leave their vehicles. In many places, two handicap spaces may share the same access aisle.

How Does Asphalt Paving Work

No matter if you are a beginner or a seasoned construction worker, knowing the proper method of asphalt paving can make or break your ability to be successful in this industry. No matter if you are starting your own company, work for someone else, or if you simply want to learn the basics of asphalt paving, you should know that the method is often the most important part of the job. That said, the following is a short guide on the basics of asphalt construction.

The 7 Areas of Pavement Construction

If you are searching for the basics of pavement construction, they are as follows:

  1. Site prep: Before you are able to begin paving, you must make sure the site is properly prepared. This can involve the replacement of areas that are extremely damaged, milling, applying of a leveling course, and more. Every site is different. However, you need to make sure each site is properly prepared before you can begin construction.
  2. Demolition and removal of old material: Next, you must demolish and remove any materials and debris that may stand to adversely affect your paving efforts. This can provide the use of bobcats, forklifts, large dump trucks, forklifts, heavy machinery, and more. The purpose of this step is to remove the existing surface, so your site can be prepared to receive the new asphalt.
  3. Grading: The purpose of this step is to make sure the area is prepared for the appropriate water drainage necessary to sustain the new pavement over time. Using various tools and technology (most often, laser transit), this step is done to ensure the new pavement will not be greatly damaged by rain, water, and other watery elements.
  4. Base: One of the most important parts of creating new asphalt pavement is to ensure that the sub-base is laid properly. As we know, having a stable foundation is vital to being able to properly build anything. This is because the sub-base serves as a stable support for new pavement. Additionally, the sub-base is also important because it can help protect the new asphalt from the winter elements.
  5. Binder: Next, the binder is added. This consists of a larger aggregate and oil mixture, which makes it exceptionally strong and durable. In short, the binder is considered to be the strength behind all new asphalt surfaces.
  6. Final surface layer: Once you had added the binder, it is now time to install the top layer of your asphalt surface. This is a smaller aggregate mixed with sand and soil. The combination of the previous material mixed with this layer creates the smooth, shiny, jet black asphalt, which most are accustomed to.
  7. Joints/transitions: Lastly, since most surfaces are connected to things such as driveways, parking lots, and roadways, asphalt construction workers must take the time to smooth the transition spaces between the new and older surfaces. This not only makes everything safer, smoother, and sturdier, but it also makes everything appear more uniform and professional.

Overall, there are various methods of asphalt paving. No matter which method you choose, you must be sure that you are completing each step with the utmost precision and professionalism. Otherwise, the new asphalt will become akin to old asphalt and will thus, will need to be redone by a contractor or company that can.

Why Is Drainage Important for Asphalt Pavements?

If you’re planning on building a parking lot or sidewalk, one of the most important things that you need to consider is drainage. Unfortunately, this is often overlooked because it’s not something you can see when you look at a parking lot. Water is the number one culprit in deteriorating asphalt, but with proper planning, you can avoid water damage and deterioration, and ensure the longevity of your site.

Warning Signs of Poor Drainage

If your parking lot has a weak drainage system, it’s pretty evident not too long after your project is complete. If your site has poor drainage after completion, a few of the warning signs you may experience include:

  • Stagnant water pooling in areas, and running down the lot
  • Evidence of rock, sand, or dusty residue in low spots indicated that the water is breaking down the asphalt
  • Water coming through exterior walls and structures

What happens if your site doesn’t include drainage?

Without proper drainage, the longevity of your site and structure will decrease rapidly. Poor drainage can lead to damaged exterior walls, cars, pedestrians, infect local water resources, and penetrate the asphalt’s surface. As standing water penetrates the asphalt, it gets into the subsoil and weakens the base causing cracks. If you want to ensure that your pavement is durable and longlasting, make sure that your asphalt company incorporates appropriate drainage planning into your project.

Drainage Features for Consideration During Planning

When planning proper drainage for your asphalt paving project, there are a few features that you need to take into consideration for your install. Your asphalt company should be able to provide you with an analysis and assessment of your site and present you with the best drainage options for your particular needs. Here are a few areas of consideration that your asphalt company will address during planning.

Slope

If your site is level and prime for pooling water, your planning should include creating a hill. A slight slope (2% grade) in your parking lot or sidewalk allows the water to flow to the outside and not pool in the middle.

Water Direction

Your drainage system should be designed to direct the water away from the exterior walls and create a path to exit appropriately. You need to make sure that water has a place to go that isn’t in your parking lot!

Asphalt Curbing

Including curbing in your planning and design can help you direct water into grassy areas, by providing a tunnel through the curb line. At the end of the curb line, you’ll have installed a drainage point.

Drains & Inlets

Strategically placing drains and inlets around your site gives water an appropriate place to go. Drains and inlets work well with slopes, directing contaminated water.

Pollution Control

Water coming out of parking lots and sidewalks can pick up a variety of pollutants as it flows through your site. Proper drainage planning includes consideration of where the water’s final destination is. It should be in a place that will not infect the water system and disposed of appropriately.

Planning the construction of a parking lot or sidewalk can be a lot of work, but unless you want to deal with numerous maintenance issues like cracks and breaks, make sure that drainage planning is part of your process before your asphalt pavers show up. Not only will it save you a ton of money in upkeep, but it ensures that your investment is built to last and endure for the longterm.

Why Does New Construction Need Asphalt Paving?

First off, what is asphalt? Asphalt is an aggregate of gravel, stone, sand, and other materials bound together by asphalt cement. According to the experts of The National Asphalt Pavement Association (NAPA), along with many others, there are a number of qualities of asphalt which make seeing your asphalt contractor the best choice for new construction of all types.

Durability

The smoothness of the surface helps give a roadway a longer life span, because it reduces friction from the tires that roll across it. It also makes asphalt a more efficient material to pave with, because it needs replacement less often. If properly maintained, an asphalt surface can last 25 years or longer.

Ease of Repair

While asphalt lasts a very long time, when it does need replacement or repair, that repair is comparatively easy and quick to do. For example, roadways can be paved a lane at a time by the asphalt contractor, reducing inconvenience to drivers and saving money for taxpayers.

Safety

Asphalt produces a smooth, even surface for activities such as driving. This, along with these other factors, make it the surface of first choice for roadways, parking lots, paved paths, driveways, and many other applications. The smooth surface gives better traction and contact for tires of all sorts, making it safer to drive on.

Recyclable

Asphalt is the perfect “green” paving material choice for use by the asphalt contractor. It is 100% recyclable and reusable. NAPA estimates that 100 million tons of asphalt are recycled or reused each year. And since much of asphalt used is reclaimed, that means the cost is less susceptible to market fluctuations.

Environmentally Friendly

The combination of recyclability and permanence as a resource makes asphalt paving one of the most environmentally friendly products there is. Another statistic from the NAPA: The asphalt emissions since 1970 have decreased by 97%, while asphalt production, during the same period, has increased by 250%. The smoothness of the surface reduces automobile emissions as well. Porous asphalt is often used for stormwater management. Asphalt is also utilized to line and cap landfills.

Economical

Almost all of the factors listed above mean that asphalt paving is a more economical substance to pave roadways, driveways, parking lots, or any other area where a smooth surface is desired. Asphalt lasts longer, so is replaced less often. This makes it less expensive. When it is replaced, the fact that much of it is often made from recyclable materials makes it less susceptible to current market conditions.

The Best Surface

To sum it all up, numerous qualities of asphalt paving make it the best surface for roadways, driveways, parking lots, and almost any other paved area. Certainly, the fact that it is economical should interest anybody who is planning any type of paving job. So should its durability, which figures into it being cost efficient as well. Also, there’s the fact that asphalt simply makes a great surface for vehicles to drive on. Its smoothness produces better gas mileage and your tires make better contact, which means it’s safer. And, not only does asphalt need repair less often than other materials, it is easy, inexpensive, and convenient to repair when the need does arise. Asphalt is also usually 100% recyclable. All these advantages mean your asphalt contractor can do the job better than anyone else, usually at lower cost, and it’s beneficial for the planet as well.

Repair Denver’s Harsh Winter Damage with Asphalt Repair

People from Colorado will undoubtedly tell you that while winters in the Rocky Mountains are no-nonsense, winter in Denver gets terrible. Even though the snow is considerable, the comparatively moderate winter is excellent for outdoor activities such as snowshoeing, snowboarding, skiing, and other outdoor recreation. Spring skiing and fuzzy snow aside, winter weather does not have to be much harsh to cause asphalt damage.

Moisture and cold can cause damage to concrete and asphalt structures – if you take long to safeguard your asphalt, it will get harder to repair it. Thankfully, several Colorado asphalt repair professionals can help you in protecting your asphalt from the harsh winter damage.

How Does Extreme Weather Affect Asphalt?

Asphalt is prone to the impacts of water damage resulting from extreme weather conditions, which means tons of snow and freezing temperatures in Denver. Luckily, with preventive measures and routine maintenance from Denver asphalt repair professionals, you can make sure that your asphalt remains strong as the mountain rocks.

Effects of Cold & Moisture on Asphalt

When water from ice and snow filter through the porous surface of your asphalt, it gradually erodes the structural purity of the asphalt. However, the actual damage happens when the outside temperatures go below the freezing point. When water freezes, it expands. The moisture contained in asphalt only requires a single freezing day to crack due to the strain of the expanding ice and water.

Effects of UV Rays on Asphalt

Denver city is one mile high, and that means that asphalt in Denver is nearer to the sun and the destructive effects associated with it. UV rays accelerate the rate of surface degradation, which forms small waves and soft spots across the surface of your asphalt.

Daily use and UV rays make the components that join asphalt together weak, which might lead to the fading of the black color of asphalt into a dull gray. Sealcoating cracks are the best method of protecting your asphalt from UV rays and heat whenever damage occurs and routine preventive maintenance.

How to Prevent and Repair Erosion & Damage

With some advice about paving and preventive maintenance from professionals, you can protect your asphalt from the harsh winter weather damage effects.

Repairing Storm Basins

Storm basins are constructed to hold and restrain water from the surface of your asphalt before accumulating to cause damage. But, it is not unusual for runoff from snow and a torrential downpour to move the storm basin from its designated position.

If you see water accumulating in places, it shouldn’t be or cracks in your storm basin, contact a Denver Asphalt repair professional right away. Remember that an inch of water can cause damage to thousands of dollars.

Sealcoating

It is a method used to protect asphalt from gas and oil spills. Sealcoating also prevents the spread of cracks, thus enhancing the artistic taste of the asphalt surface and increasing the durability of the asphalt construction.

Crack Sealing

Crack sealing your asphalt increases the durability of your structure by preventing debris and water from accumulating in the cracks on the surface of your asphalt.

Protect Your Asphalt from Harsh Winter Damage

Hiring professional paving contractors in Denver is the best way to protect your asphalt from the damaging effects of the harsh winter weather. From big business projects to basic repair and maintenance, they provide the best paving solutions in Denver. So, don’t hesitate to seek assistance from an expert if you notice any asphalt damage to your structure.
