This Global article shows that the damage is even more severe. There's that huge crack but the problems near the line markings beside the far left lane is also breaking up a lot.

Old image, disregard

They're pouring concrete for the pothole/sinkhole/hole on the Ironworkers Memorial tonight.

Wow concrete. Thought they’d just patch it with asphalt

Care to explain why?

Everyone kept calling it a pothole when it was a more serious problem with the deck of the bridge.

Similar to this back in Oct 2021



Seems like they're just doing a full removal of the problem sections and rebuilding it so they don't have to deal with it again.

There are plenty of concrete bridge decks with asphalt patches in the lower mainland. Just drove over one on the Dinsmore bridge today. Also there aren’t and concrete roads in the lower mainland. In short, we don’t do concrete surfaces well.

The City of Vancouver has been installing concrete pads at a lot of the bus stops. Most of the stops on East 41st between Joyce and Victoria Drive are concrete, and there are a lot of other ones on the major routes as well.

I had the idea that Marine Drive out to UBC and Gaglardi Way up to SFU used to be concrete as well. And maybe the Stanley Park causeway too. They aren't any more. Am I mis-remembering?

Asphalt patches work if there's something under it to support it. It doesn't work well in gigantic holes in the bridge deck.

Industrial Ave and a short stretch of Terminal Ave east of the 1st Ave intersection are still concrete, I can't think of any other non bridge decks in the region.

There are some old sections of concrete roads in the lower mainland from a by gone era, but they are in atrocious condition. None of them have been restored to their former glory. And for whatever reason concrete roads are no longer built new. Other than the pads at bus stops

its not "whatever reason" there is a HUGE reason why. they are MUCH more expensive to build. i have dealt with the CoV restoration fees, and concrete roads are the worst. they're insanely expensive. and unlike asphalt, you cannot just patch them. you need to make sure all the cuts are clean and at proper angles. so you end up paying for that. also, if you cut off too little, you have to replace the entire pad. you MIGHT be able to get away with only 1/2 the pad, but unlikely. so when it comes to utilities, they're a PITA to deal with.

really, it comes down to the cost to install, and then the cost to replace & patch when they are dug up. you will find way more conc. roads on the west side since prior to amalgamation the Municipality of Point Grey did mostly conc. roads.

a lot of the time you can tell where the old conc. roads were by looking at the asphalt cracks. if it looks like a grid, and the curb is shorter than normal. that is generally indicative of an asphalt overlay being done at some point. I have done this for my projects before, as it was cheaper to overlay the the entire road with asphalt than to repair 1/3 of it with conc.

Well most of Granville is concrete (?)

This article said one of the first concrete road projects was out for the Pacific Highway in 1919

They also called it "bitulithic paving". Seemed pretty common for most roads in the early 1900s.

I disagree with your statement that you can’t patch concrete streets. I mean, you SHOULDN’T, but that hasn’t stopped it from occurring all over the lower mainland. Perfect example is grant mcconachie way leading to the airport.

And concrete is more expensive up front, but has a much longer life span so less maintenance long term as opposed to asphalt. It definitely has its pros, as well as some cons

I hate concrete on US Interstate highways. Loud and lumpy. Hard pass.

Salt is more detrimental on concrete then it is on asphalt as well.

Not just salt.

Have a pool project renovation. We removed some Mechanical and found concrete deterioration. Cleaned up a bit and found a major structural failure. ( no rebar left). Had to replace the whole structural slab. About 300,000.00. we found hat the concrete may not have been sealed at a joint and 30 years of pool water slowly destroyed the slab. Needles to say the pool deck looks great now.

Progress.

nice to see, look likes its coming along well. hopefully they get it nice and level.

as for conc. roads, i like them but there are a lot of cons. they need to be use in some places, such as bus pads. look what happens to asphalt there; eek.

also, if you look at the CoV standards, youll see for arterial roads they use a conc. base with an asphalt overlay. this generally works pretty well in my opinion. it gives a nice solid base with a smooth surface on top. i assume our highways are done the same in the GVRD.

we should repave our roads more, though, i think. some intersections are a mess with the asphalt making tire tracks in all which ways.

The stretch of I-5 between Vancouver and Seattle is pretty good. Several years (?) back they installed some sort of tie bar connections between the panels in the truck lane - it's the smoothest its ever been and it seems to be holding up very well.
