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 Once structural damage has occurred, preventive maintenance treatments are no longer applicable and more involved corrective strategies are required."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.
