The pavement does not last either. Is it water based as well? Seems silly that they worry about a a mm of paint on six inches of oil based road surface.

ampm, that is so hilarious. They laydown the primer = oil, than they pave it.

Maybe they could test it on 15th avenue between central and foothills. It’s the middle of July and still no lane markers. My guess is that it will be done just in time for the snow to cover it!

“emissions of Volatile Organic Compounds”

They have to be joking…… a little bit of paint emitting VOCs, likely primarily on the day they apply it, compared to the VOCs coming from industrial emissions.

So get a permit from MoE. They are the ones permitting industrial emissions.

Which paint is tough enough to withstand the daily pounding of thousands of tires?

———

Too funny. If there are thousands of tires pounding the lines everyday that equates to a lot of people who need to turn in their licenses.

Apparently I don’t understand the standards set. They use tar (paving) to surface the earth to make our highways and roads and then they worry about what type of paint to put on top of this toxic surface? Seriously? Could someone please provide an explanation to let me know I’m incorrect in my thinking? No really…I need an explanation.

I am afraid I am unable to provide an explanation. VOCs in paint used indoors, I can maybe understand if someone were to show me the figures.

One set of VOCs that I smell virtually every time I drive through the Fraser Valley from Chilliwack to Abbotsford on the Canadian side of the border, less so on the USA side are the VOCs emitted by swine and other types of manure.

There are many research papers on that topic that are available such as:

sciencedirect.com/science/article/pii/S1352231012000040

Odorous VOC emission following land application of swine manure slurry

Abstract
Swine manure is often applied to crop land as a fertilizer source. Odor emissions from land-applied swine manure may pose a nuisance to downwind populations if manure is not applied with sufficient forethought. A research project was conducted to assess the time decay of odorous volatile organic compound (VOC) emissions following land application of swine manure. Three land application methods were compared: surface application, incorporation 24 h after surface application, and injection.

I realize VOCs include a whole range of chemicals, including oil, tars, etc.

I want to see some figures how much is released from the asphalt pavement that is 2 to 4 to 6 lanes wide and the 4 inches or so of VOC carrying paint.

gopg2015 you will have retired chasing you about the manure stink in Abby.

The green blob strikes again with no common sense re line painting. Who is making money out of all this testing?

“That’s what the provincial government intends to find out as it tests new types of paints on B.C.’s highways this year.”

Wouldn’t it be more reasonable and less costly to contact other provinces in Canada, states in the United States of America and (if necessary) northern climate countries like Sweden, Norway and Germany to find out how they have already solved this problem?

There is such a thing as the Internet, you know!

So makes who these ridicules decisions, I would suggest they suffer from the same affliction as those who venter in the hills and have visions of speaking to invisible gods.

Forget the paint … how about using laser lines!!!

Axman; “Too funny. If there are thousands of tires pounding the lines everyday that equates to a lot of people who need to turn in their licenses.”. LMAO, that made my morning, thanks.

Um Axeman did you miss all the lines that are crossed at intersections by design, crossing lines to access driveways etc.? Speaking of turning in licenses, for not paying attention.

Actually the longitudinal lines are assessed totally separately from those which cross roads and those which are words or symbols such as arrows. They often use different paint or even preformed “tape”.

Following up on the comments by Prince George, the best data I could find is from the National Cooperative Highway Research Program (NCHRP) which is a forum for coordinated and collaborative research addressing issues integral to the state Departments of Transportation (DOTs) and transportation professionals at all levels of government and the private sector. The NCHRP provides practical, ready-to-implement solutions to pressing problems facing the industry. While it is a US based program, it does include some data from 5 Canadian provinces and some cities.

The following is key information from one of their publications.

————————————

Environmental regulations have reduced the acceptable levels of volatile organic compound (VOC) content for pavement markings. The regulations and the changes brought to the types of marking materials used are discussed in this chapter. The types of longitudinal markings, pavement markers, and word and symbol markings used by state, province, county, and city agencies are described.

Transportation agencies are seeking cost-effective materials that maintain acceptable levels of retroreflectivity.

The service lives of marking materials are discussed and typical costs are presented. Service lives and typical costs were used to develop the life-cycle costs of longitudinal pavement markings. The costs of traffic delay during striping operations and retroreflectivity measurements are presented along with an example showing the effects on lifecycle cost. Descriptions of other materials that have the potential for improving nighttime visibility and safety are also presented.

The EPA rule is structured with the goal of reducing AIM-coating VOC emissions by 40% by the year 2004, based on the total VOC content of 1990’s production. The VOC limits established for pavement are

MAXIMUM PERMITTED VOC CONTENT FOR MARKING MATERIALS by 2000 150 g/L and by 2004 100 g/L

NOMINAL VOC CONTENT OF PAVEMENT-MARKING MATERIALS IN 1994

Solvent-borne greater than 450+ g/L3.75
Waterborne less than 150 g/L
Polyester resin less than 135 g/L
Epoxy resin 0 g/L
Thermoplastic 0 g/L

Life cycle cost to provide longitudinal pavement markings
White waterborne paint 7cents/ft/year – range 1 to 76 cents
White epoxy 14 cents/ft/year – range 2 to 133 cents
White Thermoplastic 14 cents/ft/year – range 2 to 84 cents

Yellow epoxy 9 cents/ft/year – range 2 to 39 cents
Yellow Thermoplastic 14 cents/ft/year – range 2 to 66 cents

There was insufficient data to provide results for yellow waterborne paint

Range of cost per foot per year extends from lowest installation cost and longest service life to highest installation cost and lowest service life.

———————————–
I too do not understand why it is taking this province so long to figure this out.

BTW, there is very little information about the off-gassing of VOCs from asphalt in place. When sections of in-place asphalt are taken, the portion that is VOC is extremely low. This is based on both European and American tests.

Even the marking materials are VOCs of the applied product. The major concern with VOCs from pavement is, of course, during the placement operations, not the in-situ state. I suspect the same is with the marking materials.

If there is such a great concern about VOCs from roads, I would keep on trying to reduce the VOCs from the vehicles themselves. The Japanese have invented a road “paint” application which apparently converts such VOCs to less harmful constituents.

It seems Sophic is having a hard time relating this topic to the BCLiberals and Christy Clark.

So all the other lines are fine in your world… OK, we’ll go with that.

Did you hear that “whoosh” sound? That was my joke going over your head.

Thank you gopg2015 for the added info you dug up! If they choose the lowest cost of installation over longevity then they ought not to be surprised if the lines need to be redone within a short amount of time.

Cheap always becomes expensive in the long run.

I have to agree, someone has already solved this problem, ask other districts that have similar weather patterns….Why not use glow in the dark paint, to make night driving safer?

I can’t wait until a solution has been found night time driving without sideline markings makes highway driving dangerous, and headlights glaring at you makes the conditions worst.

They don’t seem to be interested in repainting “side lines” or fog lines. I see some center line painting but they don’t continue with fog line painting which is important as well. When it comes to the environment, human life comes last.

acrider55: They were painting fog lines on Hwy 16 W. yesterday.

Strange, in England they stopped painting centre lines on some streets in some towns and it made people slow down and drive more carefully.

Walter198: I agree, the super bright, not properly focused headlights should really be cracked down on. If the proper headlights are used for higher wattage lights and they are aimed properly, there’s no problem. The trouble begins when people put higher wattage bulbs into conventional headlights which scatter the light everywhere and can’t be properly aimed to eliminate the glare.

Axman, telling a joke, now that is funny.

I suggest “gus” is back?? alias gopg2015.
