Question 1

What is slurry seal?

Accepted Answer

Slurry seal is a mix of asphalt emulsion, fine aggregate, mineral filler, water, and additives applied as a thin layer over existing asphalt. It seals the surface, restores texture and skid resistance, and gives worn pavement a new uniform wearing surface without the cost of an overlay.

Question 2

How is slurry seal different from sealcoating?

Accepted Answer

Sealcoat is a thin protective coating with little aggregate, while slurry seal contains graded aggregate that builds a new wearing surface. Slurry fills minor surface voids and raveling that sealcoat can't. See our Slurry vs. Sealcoat Comparison page for a full breakdown.

Question 3

What's the difference between Type 1, Type 2, and Type 3 slurry?

Accepted Answer

The difference is aggregate size under ISSA A105. Type 1 is the finest, for parking lots and low-speed areas; Type 2 is general purpose for streets and commercial lots; Type 3 is the coarsest, for higher-traffic streets.

Question 4

When should I choose micro-surfacing instead of slurry seal?

Accepted Answer

Polymer-modified micro-surfacing (ISSA A143) is built for heavier traffic, highways, airports, and filling ruts. If your pavement sees high volumes or heavy loads, micro-surfacing is usually the better fit.

Question 5

How long does slurry seal last in Arizona?

Accepted Answer

Service life depends on traffic, pavement condition, and maintenance, but a properly prepared and applied slurry seal commonly lasts several years. Crack sealing before application and routine maintenance afterward extend that life.

Question 6

How soon can traffic drive on new slurry seal?

Accepted Answer

In Arizona's warm, dry conditions, slurry typically cures within hours, though temperature, humidity, and shade affect timing. We confirm reopening times as part of your schedule and phase the work around them.

Question 7

Will slurry seal fix potholes and alligator cracking?

Accepted Answer

No. Slurry seal is a surface treatment, not a structural repair. We patch base failures and seal cracks first so the slurry goes down over sound pavement.

Question 8

What prep work happens before slurry seal?

Accepted Answer

Typical prep includes crack sealing, patching failed areas, cleaning the surface, and protecting utility covers and curbs. We spell out every prep item in your line-item proposal.

Question 9

What's the best time of year to slurry seal in Arizona?

Accepted Answer

Slurry needs warm, dry conditions to cure, so most of the year works in the Valley. We schedule around monsoon storms and cooler nights in higher-elevation areas like Flagstaff and Prescott.

Question 10

Is slurry seal cheaper than an overlay?

Accepted Answer

Generally yes. Slurry seal resurfaces pavement at a fraction of the cost of a new asphalt overlay when the underlying structure is still sound. Our free site evaluation tells you which treatment your pavement actually needs.

Question 11

Why buy slurry seal from American Asphalt instead of a broker?

Accepted Answer

We produce the material and apply it ourselves, so you get consistent ISSA-compliant mix, one accountable company, and no middleman markup.

Question 12

Do you produce your own slurry material?

Accepted Answer

Yes. We produce Type 1, Type 2, Type 3, and polymer-modified micro-surfacing to ISSA A105 and A143 gradation and mix design standards.

Question 13

Do you sell slurry material to other contractors?

Accepted Answer

Yes. Our Bulk & Wholesale Supply program provides spec-ready material to contractors, municipalities, general contractors, and HOA or property management vendors.

Question 14

Is material delivered, or can I pick it up?

Accepted Answer

Both. Delivery or pickup is confirmed per project, anywhere in Arizona.

Question 15

Do you offer custom mix designs?

Accepted Answer

Yes. We design custom mixes for specific project requirements on request.

Question 16

Can you provide documentation for bid submittals?

Accepted Answer

Yes. Data sheets and mix design documentation are available for bid submittals and project files.

Question 17

Are you licensed, bonded, and insured?

Accepted Answer

Yes. We hold three active Arizona ROC licenses: ROC 155730 (Commercial Paving), ROC 109709 (Commercial Concrete), and ROC 105759 (General Engineering).

Question 18

Do you warranty your slurry seal work?

Accepted Answer

Qualifying projects are backed by our 2-year workmanship warranty, and we walk the finished work with you before final invoicing.

Question 19

Do you subcontract the application?

Accepted Answer

No. Our own crews and equipment handle slurry seal along with paving, sealcoating, concrete, and striping.

Question 20

How long has American Asphalt been in business?

Accepted Answer

We are family owned and have been paving Arizona since 1993, with more than 1,000 projects completed statewide.

Question 21

Do you handle municipal and ADOT slurry projects?

Accepted Answer

Yes. We apply slurry and micro-surfacing for municipal and ADOT work and produce spec-compliant material for public pavement preservation programs.

Question 22

Do you work with HOAs and residential communities?

Accepted Answer

Yes. We run HOA street programs with phased schedules and resident notice so communities keep access during the work.

Question 23

Can my business stay open during slurry seal?

Accepted Answer

Yes. We phase the work with traffic control so sections of your lot or street stay open while others cure.

Question 24

Do you restripe after slurry seal?

Accepted Answer

Yes. Striping, fire lanes, signage, and ADA layout are handled in-house so your lot is ready to reopen without a second vendor.
