FAQ

Besides making your parking lot look much better, sealers protect asphalt from the destructive elements of weather, gas, oil and other chemicals that damage the paved surface.

All brands of pavement sealer are definitely NOT EQUAL. Federal Spec. sealers require dilution rates of up to 40% of water. Even if several contractors use the same product, most contractors will use mix designs to their advantage. M&D Blacktop follows the manufacturer’s specification. In fact, M&D Blacktop chooses a dilution rate of 25%-30%; this is the low (best) end of the dilution rate scale. Some contractors have been known to over-dilute their sealer. These products have lower solids content and cannot hold as much sand, causing a slippery surface when dried. Additionally the coating will not perform properly and money will be wasted.

The best way to apply asphalt sealer is to use the following method:The first coat of sealer should be applied using a motorized, seal coating, squeegee machine. The squeegee machine will help force sealer into the pores of your asphalt surface, filling in voids and providing a well sealed surface.The second coat can be applied using a spray unit specifically designed for seal coating. This will provide a nice even, uniform coat of sealer, suitable for driving and walking.In some cases spraying both coats of sealer is acceptable.

It is very important to clean out cracks prior to filling them. Debris left in cracks will cause the crack sealant to break loose prematurely and work free of the crack. In cases where vegetation is growing through cracks or there is moisture in cracks from a previous rain, it is very important to use a propane powered heat lance to remove the moisture and/or vegetation prior to applying crack sealant.

Pavement sealer should only be applied when the surface temperature is 40 degrees and rising and there is not a significant rain hazard in the near future. If the possibility of rain is too great and we feel there is a real danger in having your property damaged or your sealer washed away, we will contact you and re-schedule the project.

Understanding the difference between asphalt paving and asphalt sealcoating is essential for maintaining and improving your surfaces. Here’s a breakdown:

Asphalt Paving

Asphalt paving involves laying down a new layer of asphalt to create a smooth, durable surface. It’s typically used for building new driveways, parking lots, or roads, or for resurfacing severely damaged areas. Paving addresses structural issues like cracks, potholes, or uneven surfaces, ensuring a solid foundation for heavy traffic and long-term use.

Key Features:

  • Creates a new or refreshed asphalt surface.
  • Repairs significant structural damage.
  • Ideal for new construction or resurfacing older areas.

Asphalt Sealcoating

Sealcoating is a protective treatment applied to an existing asphalt surface. It helps extend the life of your pavement by sealing small cracks, preventing water infiltration, and shielding it from harmful elements like UV rays, oil, and chemicals. Sealcoating also improves the surface’s appearance by restoring its rich black color.

Key Features:

  • Prevents damage and slows down wear and tear.
  • Protects asphalt from environmental elements.
  • Enhances curb appeal with a fresh, clean look.

Which One Do You Need?

If your asphalt is in good condition but needs protection and a visual refresh, sealcoating is the way to go. However, if your surface is severely cracked, uneven, or structurally compromised, paving or resurfacing may be necessary.

The lifespan of asphalt depends on factors like proper installation, maintenance, and the level of use. On average, well-installed and maintained asphalt can last 15 to 20 years, and in some cases, even longer.

Factors Affecting Asphalt Longevity:

  1. Quality of Installation: A strong, properly constructed foundation is critical for long-lasting asphalt.
  2. Traffic Levels: High traffic or heavy vehicles can wear down asphalt more quickly.
  3. Climate: Freezing and thawing cycles, UV exposure, and moisture can impact asphalt durability.
  4. Maintenance: Regular sealcoating, crack filling, and timely repairs can significantly extend the life of your asphalt.

Tips to Maximize Asphalt Longevity:

  • Schedule sealcoating every 2-3 years to protect against weather and wear.
  • Repair cracks and potholes promptly to prevent further damage.
  • Keep the surface clean and free from standing water or chemical spills.

With proper care, your asphalt surface can provide a durable and cost-effective solution for decades. Contact M&D Blacktop Co. for expert advice on installation and maintenance to get the most out of your asphalt!

Asphalt crackfilling is the process of filling and sealing cracks in asphalt pavement to prevent further damage. It’s an essential maintenance step that helps extend the life of your asphalt by addressing small problems before they become bigger, more costly repairs.

Why Is Crackfilling Important?

Over time, asphalt expands and contracts due to temperature changes, traffic, and natural wear and tear. This can lead to cracks forming on the surface. If left untreated, these cracks allow water to penetrate the pavement, weakening the base and leading to potholes, larger cracks, and other structural issues.

How Does It Work?

  1. Cleaning the Cracks: The process begins by clearing out debris, dirt, and vegetation from the cracks to ensure the filler adheres properly.
  2. Filling the Cracks: A specialized rubberized material is poured or injected into the cracks. This material remains flexible, allowing it to expand and contract with the asphalt during temperature changes.
  3. Sealing: The filled cracks are smoothed to create a durable, watertight seal that prevents further damage.

Benefits of Crackfilling

  • Prevents water infiltration and erosion of the asphalt base.
  • Extends the lifespan of your pavement by mitigating further cracking.
  • Saves money by avoiding more extensive repairs or resurfacing.
  • Improves the appearance and safety of your asphalt surface.

Regular crackfilling is a cost-effective way to protect your investment and keep your pavement in top condition. Contact M&D Blacktop Co. to schedule a crackfilling service and ensure the longevity of your asphalt!

We can usually have your parking lot re-opened to traffic the day after work is completed, weather permitting. M&D Blacktop will provide barricades and caution tape to ensure the property is blocked off.

Asphalt should be seal coated every two to three years. The amount of traffic is one deciding factor. Surfaces that receive light traffic, like home driveways and small businesses, require re-coating less frequently than parking lots receiving moderate to heavy traffic.

 

This is a great question, pavement sealer will not make the surface slippery if applied properly. We use a sand-slurry mix of pavement sealer. Silica sand is mixed into the sealer at a rate of 3-6 pounds per gallon of sealer depending on the quality on the sealer you use. Not all contractors use this type of mix, so be sure you find out if sand is mixed into their material. If sealer is applied without sand mixed into the sealer, then yes, your parking lot will be very slippery. This is a major liability issue for business owners.

 

Hot-pour crack filler is a flexible, rubber-like product that starts out as a solid, rubber block or cube, and is melted down in a special melter. Once melted, the sealer is applied over the cleaned out crack. Once cooled, it can be sealed over, or driven on without any problems.

 

Yes, we can change your existing parking lot layout if you wish. To do this, you must first have the old lines painted over with traffic blackout paint. A word of caution….the old layout lines will most likely be discernible as a dark shadow-like outline under the sealer.

 
 

Absolutely. We prefer to schedule seal coating and line striping for weekends.

 
 

Parking lot striping is about more than just aesthetics – it plays a crucial role in safety, functionality, and compliance. Here’s why it matters:

1. Safety

Clear, well-defined lines guide drivers and pedestrians, reducing the risk of accidents. Proper striping helps ensure smooth traffic flow, designates safe parking areas, and highlights pedestrian crossings or fire lanes.

2. Maximizes Space

Efficient striping maximizes your parking lot’s capacity by clearly marking spaces and optimizing the layout. This ensures that you can accommodate more vehicles without overcrowding.

3. Compliance with Regulations

Striping ensures your parking lot meets local codes and accessibility standards, such as ADA (Americans with Disabilities Act) compliance. Properly marked handicapped spaces, fire lanes, and loading zones are essential to avoid fines and ensure accessibility for all.

4. Professional Appearance

A freshly striped parking lot boosts curb appeal and creates a positive first impression for customers, tenants, or visitors. It reflects your commitment to maintaining a safe and professional environment.

5. Longevity of the Surface

Striping also helps protect your asphalt by minimizing unnecessary wear and tear caused by disorganized or improper use of the space.

Whether you need new striping or a refresh, M&D Blacktop Co. can help ensure your parking lot is safe, efficient, and compliant. Contact us today for expert striping services!

Asphalt milling is necessary when a pavement surface has significant damage but the underlying foundation is still in good condition. It involves removing the top layer of asphalt to prepare the surface for a new layer, offering a cost-effective alternative to full reconstruction.

When Should Asphalt Milling Be Done?

  1. Surface Damage Without Structural Issues
    If your asphalt has extensive surface problems like cracks, ruts, or potholes, but the base is still solid, milling removes the damaged layer without disturbing the foundation.

  2. Uneven or Poor Drainage
    Milling can address issues with water pooling or uneven surfaces by leveling the pavement and restoring proper drainage.

  3. Preparing for Resurfacing
    Milling creates a clean, even surface for new asphalt to adhere to, ensuring a long-lasting result.

  4. To Meet Elevation Requirements
    Milling is necessary if your asphalt needs to match surrounding areas, such as sidewalks, curbs, or entrances, especially when resurfacing would raise the height too much.

  5. Cost-Effective Repairs
    When total reconstruction isn’t necessary, milling offers a budget-friendly way to restore the surface without replacing the entire pavement.

Signs You Might Need Asphalt Milling

  • Widespread cracks, raveling, or potholes.
  • Drainage problems like standing water.
  • A surface that feels uneven or unsafe for vehicles and pedestrians.

M&D Blacktop Co. specializes in asphalt milling to extend the life of your pavement and restore its functionality. Contact us today to see if milling is the right solution for your project!

Whether you can opt for an asphalt overlay or need a full mill and pave depends on the condition of your existing pavement. While an overlay is quicker and more cost-effective, it’s not always the right solution for every situation.

What Is an Asphalt Overlay?

An overlay is the process of adding a new layer of asphalt on top of an existing surface. It’s ideal for pavements that are still structurally sound but show surface-level wear and tear, such as minor cracks or fading.

When an Overlay Works

  • Minimal Surface Damage: The existing pavement has only minor issues like small cracks or surface wear.
  • No Structural Problems: The base layer is stable, with no significant damage or deterioration.
  • Cost Efficiency: An overlay is less expensive and faster than milling and paving, making it a good option for pavements with minimal damage.

When You Need Milling and Paving

If the existing asphalt has extensive cracks, potholes, or base damage, a mill and pave is necessary. This process removes the damaged surface layer before applying new asphalt, ensuring long-term durability. Adding an overlay without addressing these issues can result in:

  • Cracks reflecting through the new layer (called “reflective cracking”).
  • Poor drainage or uneven surfaces.
  • A shorter lifespan for your pavement.

Which Option Is Right for You?

If your pavement is in relatively good condition and free from structural issues, an overlay can be a cost-effective way to refresh the surface. However, if there’s extensive damage, milling and paving will provide a stronger, longer-lasting solution.
