What causes rust in asphalt?

Cause: Small particles of iron ore are mixed in with the stone that is used to make your asphalt driveway. Water leaches up through the bottom of your driveway, causing the metal particles to oxidize. The resulting rust particles rise to the surface of the driveway leaving stains and streaks on the asphalt.

What happens if asphalt gets wet?

When rain comes into contact with fresh asphalt, it causes the oil to rise to the surface which can affect the curing time and the finished product. If asphalt is paved while it's raining, it can reduce the overall quality of the asphalt. Rain also jeopardizes the stability of the subsoil.

What is the life expectancy of asphalt?

Asphalt roads are likely to last approximately 18 years. Actual outcomes, however, depend on more than performance characteristics of concrete vs. asphalt. When estimating road life, we need to consider additional factors.

What does asphalt look like when it starts to deteriorate?

Even in normal conditions, substantial deterioration can begin to take place after 3 to 5 years. It is normal after this amount of time for asphalt to begin to turn gray, become brittle and start cracking. Water begins entering the cracks, freezes and thaws during the yearly cycle and causes larger cracks and potholes.

Is asphalt still soft after a year?

Since asphalt needs time to harden and cure, usually 6-12 months, your parking lot or driveway will remain soft and pliable until then. You may walk on the new pavement immediately, but keep automobile traffic off of it for at least 3 full days and longer in hotter temperatures.

Why is my driveway rusting?

of biocide per 1000 gal. of sealer. He says asphalt-based sealer is prone to bacterial spoilage, which actually breaks down the asphalt and destroys the sealer. Contractors can detect such spoilage if they notice foaming of the material or volume expansion, usually indicated by bulging of the container.

What happens to asphalt when it gets hot?

Heat Expansion

Just like other materials, asphalt contracts under cold conditions and expands when it gets warm out. And when it gets really, really hot this expansion can cause issues. Pavement edges may curl, cracks may be pulled farther apart, or new cracks may form due to the pavement motion.

What color is rust on asphalt?

Asphalt allows water to penetrate through it. The moisture accumulating on your parking lot goes into the pavement. If your pavement has pyrites in it, it becomes wet, the pyrites (iron) then begin to rust. The rust stain eventually comes to the surface causing the ugly brown spots or streaks in the asphalt.

Additives can also be introduced in the asphalt binder. Iron, slag and recycled glass can give the asphalt mix red, yellow, green, brown or orange tints.

Is it better to remove rust or leave it?

Removing surface rust from surfaces improves the appearance, but it's importance goes beyond the decorative. Rust, left unchecked, can lead to pitting and structural damage to products and components and can impact the performance of instrumentation, contaminate flow paths, and impact reliability.

Can you stop rust without removing it?

Apply a Dry Coating

For metal parts or components that need to stay clean or provide a solid grip, a rust preventative dry coating is ideal. Dry coating rust prevention products such as ARMOR's Dry Coat Rust Preventative can be applied via spray, dip or wash. Once they dry, the protective barrier is in place.
