Phoenix’s Pavement Preservation and Asphalt Maintenance Consultants
Holbrook Asphalt is the Phoenix Metro and Tucson area’s most innovative pavement and asphalt preservation company.
You don’t need us to tell you that Phoenix gets hot. The intense UV rays that are generated by the Arizona sunshine can have detrimental effects on asphalt.
That’s where we come in. Holbrook Asphalt Company works with the Cities, Towns, and Homeowners Associations in Arizona to help extend the life of asphalt. Our Pavement Preservation Consultants are Arizona pavement experts and have been helping the Phoenix, Scottsdale, Mesa, Tempe, Chandler, Gilbert, Queen Creek, Peoria, Tucson, and the surrounding areas gain the maximum extension of asphalt life for over a decade.
We have team members based in Phoenix and Tucson, and we take great pride in providing services to those cities and the surrounding areas.
Our Work Around Phoenix and Tucson
Trilogy at Verde River is a prestigious gated community located just east of North Scottsdale. The community boasts entertainment and fine dining options, one feature of Trilogy at Verde River, which will contribute to the quality of the residents’ lives in a very different way. Early in the community’s life, Trilogy at Verde River decided that they needed to protect their infrastructure from the damaging effects that the intense Arizona sun can have. The community knew that a preservation treatment would benefit owners in the long run by extending the life of one of the community’s most expensive assets, their roads. After doing their due diligence, the Trilogy at Verde River ultimately decided to use HA5 High Density Mineral Bond to extend their roads and improve the community’s aesthetics. Hear Lori Stange talk about why they chose HA5.
This Scottsdale Homeowners Association evaluated the performance of seal coats that had been previously installed and found that they hadn’t been getting the most for their money. The Arizona sun can have a detrimental effect on asphalt. The intense UV rays cause the binder that holds asphalt together to deteriorate faster, leading to dry, brittle material that begins to crack. The Saguaro Highlands Community in Scottsdale, AZ recognized that they needed to protect their asphalt. After doing their due diligence, they discovered HA5, a High Density Mineral Bond, that would allow them to extend the life of their asphalt much longer than a traditional seal coat. Joe Regan explains the process they went through.
Scott Leska has over 24 years of engineering experience that includes ADOT. Most recently Scott served the Town of Marana for 15 years in various Engineering roles including the Engineering Division Manager. Scott is well known for his forward thinking, out-of-the box approach to managing complex problems. Scott introduced HA5 High Density Mineral Bond to Marana in 2012 with installations that continue to outperform traditional surface treatments that the town had used previously. Scott Leska is a sought-after engineer who left public works in 2019 to pursue his passion to use his engineering knowledge in the defense industry.

Phoenix and Tucson Pavement Preservation Experts
Extending the life of your asphalt assets is what we do and it’s what we’re passionate about. With over 20 years of experience, we’ve helped some of the Phoenix area’s largest homeowners associations and cities extend the life of their asphalt assets.
For many communities in the Phoenix and Tucson areas, asphalt is one of their community’s biggest expenses. That’s why more and more communities are extending the life of one of their community’s most valuable assets with Holbrook Asphalt.
We’ve been able to provide the area’s highest-quality solutions by dedicating ourselves to innovation and customer service. Our dedication to using the highest quality products that provide the most value over the greatest number of years is why we utilize HA5 High Density Mineral Bond. HA5 is the only product that meets the rigorous qualifications of the High Density Mineral Bond Specification and has been trusted by hundreds of municipalities and thousands of private communities. We are proud to be the only company in Arizona that can deliver the quality and longevity that HA5 has to offer along with traditional crack sealing.
Engineered to Preserve
HA5 was developed to meet the demand for effective asphalt preservation on residential roadways without the negative side effects of chip seals or slurry seals. Specifically engineered to preserve the native asphalt binder, HA5 is exceptional at preventing oxidative damage. As a result, you will have streets that last longer and cost less to own.
What is HA5
HA5 is arguably the fastest-growing trend in pavement preservation, now in use by over 200 public agencies. Meeting the stringent demands of a High Density Mineral Bond, HA5 is uniquely emulsified with a near neutral charge that is able to hold a unique blend of fine aggregates. Limiting oxidative damage from moisture is fundamental to HA5’s preservation qualities. But just as critical to the prevention of oxidative damage from moisture is preventing oxidative damage from Ultraviolet (UV) radiation. HA5 combats oxidation from UV by including limited amounts of specific polymers to reflect damaging UV rays.
HA5 features include:
- A specialized, non-ionic emulsion specifically engineered to carry mineral types that are not compatible with anionic and cationic emulsions.
- A blend of ultra-dense, angular-shaped fine aggregates formerly unavailable in a thin surface treatement.
- A combination of specific polymers that combat oxidation by deflecting Ultra-Violet Rays.
The former head of pavement materials at the country’s largest state DOT, published research findings that identified pavements with HA5 High Density Mineral Bond installed had a 67% delay in the age-hardening of the asphalt. Keeping asphalt flexible prolongs the useful life of the pavement and reduces cracking resulting from pavements becoming brittle.
HOW HA5 IMPACTS ASPHALT AGING
“Using conventional as well as leading-edge testing methods to identify the age hardening of the asphalt binders, researchers have identified a 67% delay in the age hardening of the asphalt binder with HA5 installed as a pavement preservation strategy. This ability to reduce flexibility loss supports an in-field case study where after just a four-year period a side-by-side comparison identified cracking to be reduced by nearly 9 times with HA5 installed.”
Tested, Proven Performance
An evaluation was completed comparing HA5’s performance in a side-by-side comparison with another treatment. On one section, a commercially available polymer-enhanced asphalt emulsion was installed within a week of an adjoining HA5 installation.
The original paving of both sections was done as one project nine years before the side-by-side maintenance treatments were installed.
Each of the treated sections had multiple crack samples taken. The HA5 treated section had sample areas examined that calculated to an average .007 of the surface experiencing cracking and the polymer enhanced asphalt emulsion sampled road surface was found to have .06 of the area with cracking. That’s an astounding 857% more cracking in the non-HA5 treated pavement compared to the road having had HA4 installed.
Owners and managers responsible for asphalt roads and parking surfaces realize significant reduction in pavement lifecycle costs with HA5 due to the asset preservation qualities and durability of the installations. In use by public agencies nationwide, it is also the choice for school districts, religious organizations, medical providers, and various business types for asset preservation.
Research on binder elasticity and pavement permeability proves that asphalt treated with HA5 significantly increases the useful life of asphalt pavement and therefore lowers the cost of transportation infrastructure.
- Highest Return on Investment (ROI)
- Highest Pavement Condition Index (PCI)
- Highest Public Acceptance Rating (PAR)
There is no one-size-fits-all tool in the preservation toolbox, but for subdivision roadways, HA5 provides the highest benefit per dollar spent.
