Like Stained Concrete Petraviam Offers Colors Naturally
Paving with asphalt wasn't an option on this job, the grade was too steep and the look had to be natural. At 26 degrees, the slope would have been challenging for stained concrete.
Paving with Petraviam gave this property a stunning look, similar to decomposed granite, but rock hard. The surface provides the traction necessary for automobiles to safely negotiate the slope rain or shine.
Unlike stained concrete, the color is saturated all the way down through the 4-inch lift. In the unlikely event of a scratch or gouge the color will show through consistently.
While this property wanted a dramatic red tint, Petraviam can be tinted brown or black and various shades of grey to match asphalt, naturally, without introducing the toxins asphalt does.
Paving with Petraviam is Better Than Asphalt or Concrete
Just how amazing is paving with Petraviam? Look into the numbers and discover what we've known for over a decade.
Petraviam paving stands up to a pounding, 128,000 pounds per square inch as tested by a third party engineering firm. That's double the standard for asphalt and in excess of most county and municipal requirements.
Petraviam's wet skid number is greater than 35, equivelent to concrete and exceeding Department of Transportation safety requirments.
And Petraviam paved surfaces last for years. The oldest installation is 11-years old and counting. Let's see asphalt do that.
Even with the superior performance of Petraviam paving, the key question of cost always comes up. We hired another third party research firm to look at the cost of concrete and asphalt installation in the central Texas market. Comparing 10,000 square foot projects that included ground preparation and 4-inches of surfacing. They had some trouble getting enough asphalt projects with 4-inches or overlay, many were only 2-inches. The concrete projects averaged $5.53/sq.ft, asphalt averaged $2.48 and Petraviam averaged $1.83/sq.ft. Actual pricing may vary depending on the size and scope of the project. County and municipal work is often priced by the mile.
For 1/3 the cost of concrete, 3/4 the cost of asphalt, Petraviam delivers a rock hard, 128,000 psi surface that lasts for 11-years and counting, is 100% organic and contains 0 carcinogens or volatile organic compounds. Paving with Petraviam creates a beautiful rock hard surface that is easier on your wallet and safer for the environment.
Gravel, road base and asphalt can't stand up to extreme erosion
Petraviam paving solutions stand up to erosion. The problem with gravel, road base and decomposed granite is they all wash away, creating mud and later dust coating your vehicles and equipment when wet and dry.
Now, imagine beating your driveway with 100 PSI of water pressure. More realistically, washing your truck with a high pressure hose or power washing a farm tool. Mud everywhere, right? Watch this video to see how paving with Petraviam stands up to pressure.
Now don't try this at home, just think about what would happen if you performed the same test on your gravel, chip seal or asphalt paved surfaces. Newer asphalt may hold up, older asphalt and chip seal would disintegrate almost as quickly as the road base in this video.
Third party testing proves Petraviam paved surfaces are twice as strong as asphalt, on par with concrete. Additional research proves that over time, Petraviam gets harder.
Facility operators know what happens when it rains, operations bog down as equipment sinks in the mud. Petraviam paved operations run smoothly. Home builders know the pain too, sub-contractors getting stuck, mud all over the project, and delays, resulting in increased building costs resulting in lower margins and unhappy customers.
Can your ranch road or facility lot stand up to hurricane driven rain? Petraviam paved surfaces do, beautifully. Moving buckets of clear rain water gently and safely off the surface without leaching the carcinogenic volitile organic compounds found in asphalt or chip seal.
Petraviam paving stands up to the power of water, eliminating mud, pot holes and washouts, eliminating the dust that follows when things dry out.
Petraviam out performs chip seal
Chipseals, also known as tar and chip, chip seal or seal coating, are constructed by evenly distributing a thin base of hot bitumen or asphalt onto an existing pavement and then embedding finely graded aggregate into it. The aggregate is evenly distributed over the seal spray, then rolled into a smooth pavement surface. On average the chips and asphalt are no thicker than 1/4 inch.
No state Department of Transportation recommends putting chip seal directly on to road-base or flex-base. Texas, Ohio, Indiana, Montana and even the asphalt institute2 only recommend using chip seal to bind up exisiting asphalt surfaces.
Aside from being a thin layer, chipseal has othe drawbacks:1
The challenge with chip seal starts with the foundation or base layer. The Asphalt Institute reports:2
"Chip seals are not suited for all pavements; the existing structure should be sound with only minor surface defects. They are not appropriate for rutted, potholed, or severely distressed surfaces. Once structural damage has occurred, preventive maintenance treatments are no longer applicable and more involved corrective strategies are required."
But all too often cost savings and hasty application practices cause installers to spread asphalt over the defects and loose agregate hoping to bind or hide the defect before putting down the chips. Those chips then get shaken loose as vehicle traffic moves, damaging windshields and leading to a loss of traction, leading to property damage, injury or even loss of life. Again, no state or federal agency or even the asphalt institute recommends installing chip seal over road base or any unpaved surface.
Adding fog-seal on top of chip seal further reduces traction ratings by 30% and over time up to 50%.5
Petraviam is up to 10-times stronger than chip seal when applied conventionally, saturating into the sub-base material. When applied topically, it outperforms chip seal by penetrating the sub-base and creating a bond the sub-base that is 3/4 to 1-1/4 deep. When infused into a 3 or 4-inch lift, Petraviam creates a rock hard paved surface through out.3
Petraviam is organic and does not contain the Volatile Organic Compounds and carcinogens found in the asphalt used in chip seal.4
Applying Petraviam topically on properly prepared roads is cost effective compared to chip seal. Pave naturally, chose Petraviam.

Testing proves Petraviam is stronger than asphalt
Petraviam stands up to a pounding, wet or dry, exceeding asphalt specifications. Petraviam hired a third party engineering firm to test three of our surfaces, our oldest 11-year old site, and two more. They told us just how exceptional Petraviam paving was.
Petraviam paving improves with time
For research purposes, we continue to test Petraviam for durability and performance. During rain or shine, Petraviam maintains a hard and impervious surface.
Following a Brinell hardness methodology, we measured wet compacted road base, dry compacted road base and a county road against Petraviam roads for hardness. Wet Petraviam roads were 300 percent harder than wet road base that had been compacted. Over time, as the solution oxidizes, the Petraviam paved surface continues to get harder.
What does it mean for counties and municipalities? Safer roads, happier citizens, reduced road and bridge expenditures. The county road below was paved 2-months ago with an asphalt seal coat, when it rained it turned to mud with a relative hardness of 0.114 compared to the adjacent Petraviam paved ranch road with a hardness of 3.39. The photo below tells the tale; ruts and mud that will turn to dust and erosion over time.
What does it mean for facilities operators and logistics companies? Petraviam stands up to 80,000 pound trucks running all day, every day, rain or shine.
