Road paint, is it getting more slippery?

Not too sure about the no snow states, but where the plows roam and the de-icing chemicals flow I had another unintentional "mini-slider" this afternoon.

I have long been aware road paint is a wee bit slippery especially when wet and could be just a few too many coincidences this season but I think road paint is getting more slippery.

Anyone in the stripe painting business or road and traffic engineering know if I am getting paranoid or perhaps some truth to this?

Are they starting to use epoxy based paint mixes or something else in the road paint brew?

Don't know about changes in paint but there are many places that are using a plastic sheet type if marking (they heat it to get it to stick) and those can also be very slick.

I noticed when the repainting of street marking was done a short time back I had a slip going over one and never had that happen before.:eek:

Thermoplastic is being used more often - for reasons of durabiilty. You can get a couple of addition years of use without reapplication as compared to traditional paints. However, it is slicker than hot chicken grease on your hand when turning a stuck doorknob when new and damp. And, based upon what I've seen (and I work as a traffic engineer), most agencies care little for the potential impact to scoot riders - even as compared to bicycle riders.

I can't say that there's a causal relationship, but glass microbeads are used (for reflectivity of the striping) quite often, too.

For environmental reasons, I ve heard, the chemicals in paint mixtures have had to change.

If you are familiar with I Street as it approaches 15th Avenue in Anchorage, I can tell you the white stripes were slick in the '70s for a bike pushing the envelope uphill around the "Ess" curve.

Thanks for the info Daylight and Scooby. I might not be getting paranoid afterall.
