Mastic Repair Services | MB Asphalt Maintenance

What is Mastic and Why it Matters

Mastic is a hot-applied, rubberized, aggregate-filled repair material used for wide cracks, failed seams, transitions, and even small potholes. It is designed for pavement damage that is too severe for standard crack filling but does not yet require full-depth asphalt replacement. Unlike traditional crack sealant, which is poured into narrow cracks as a liquid, mastic is applied through a heated melter and dispensed into a rectangular drag box that is pulled across the damaged area. This method forces material down into the defect while leaving a reinforced surface band on top, creating a flexible, load-resistant waterproof repair.
Mastic is a fantastic option because wide cracks and surface defects allow far more water intrusion than small, sealed cracks. Once water penetrates beneath the surface, it weakens the asphalt structure and the base below, accelerating failure through freeze-thaw cycles, traffic stress, and erosion. Standard crack filling in these areas often fails prematurely because the opening is simply too large and unstable. Mastic provides a reinforced repair that moves with the pavement, resists traffic wear, and dramatically slows the spread of deterioration. By sealing and strengthening weak pavement before full structural failure occurs, mastic repair helps extend pavement life, improve safety, and delay the need for costly reconstruction.

When to Choose Mastic Repair

Mastic repair is the right solution when pavement damage has progressed beyond narrow cracks but does not yet require full-depth replacement. It is ideal for wide cracks, crumbling edges, failed seams, and small potholes where standard crack filling is no longer strong enough to hold under traffic movement.
While mastic is still a premium repair option, it offers a strong alternative to full replacement of the pavement when the underlying base is still structurally sound. It reinforces weakend pavement, seals out moisture, and significantly extends surface life without the disruption of full reconstruction. When damage is minor, crack filling remains the best preventative option, and when base failure is present full-depth repair is still the best option. Mastic fills the critical middle ground between these two extremes.

Our Process

Surface Preparation

We begin by thoroughly cleaning the damaged crack or defect to remove dirt, debris, loose asphalt, and moisture. Proper surface preparation is critical to ensure the mastic bonds tightly and performs as intended.

Material Heating & Conditioning

The mastic is heated in a specialized melter until it reaches the precise working temperature. This allows the material to flow properly while maintaining its strength, flexibility, and aggregate structure.

Mastic Application

The heated mastic is dispensed into a rectangular drag-box applicator and pulled directly across the damaged area. This forces material down into the opening while creating a reinforced surface band that strengthens the surrounding pavement.

Final Set & Traffic Readiness

Once applied, the mastic is allowed to set and harden before reopening the area to traffic. The finished repair creates a waterproof, flexible, and load-resistant seal designed to withstand movement and heavy traffic.

FAQ

How is Mastic Different From Crack Filling?

Mastic is a binder mixed with aggregate, creating a reinforced repair for larger cracks and distressed areas. Crack filling uses a flexible rubber material designed to seal standard cracks and move with the pavement.

Is Mastic Repair Permanent?

Mastic is a long-lasting repair, more durable than rubber crack filling, but like all asphalt maintenance solutions, it is not permanent. It significantly extends pavement life when used properly and at the right time, delaying the need for full-depth replacement.

How Long Does Mastic Take to Cure?

Mastic typically sets quickly and is often ready for traffic within a few hours, depending on temperature and site conditions.

Is Mastic Better Than Full Asphalt Replacement?

Mastic is not a replacement for full reconstruction when base failure is present. However, when the underlying structure is sound, mastic provides a powerful middle-ground solution between basic crack filling & full replacement.

Can Mastic be Used on Parking Lots & Roadways?

Yes. Mastic is commonly used on commercial lots, industrial sites, & roadway surfaces where durability, flexibility, and moisture protection are critical.
