Runway asphalt ramp damaged by aircraft blast

Owen Roberts International Airport, Grand Cayman

(CNS): The damage to the runway at Owen Roberts International Airport, which caused it to be closed Monday afternoon, was caused by aircraft blast “lifting” the temporary asphalt ramp that had been placed the evening before, Sunday 9 February, according to the Cayman Islands Airport Authority. The work was part of the “runway rehabilitation” project currently underway to strengthen the runway.

Runway operations were suspended Monday at 3:23pm and remained closed for approximately two and half hours, reopening at 5:55pm Monday evening with a “re-declared distance”, which allowed limited flight operations to resume. Full flight operations resumed today, Tuesday, at 7:00am, the CIAA said in a release issued this afternoon.

The authority said that safety inspections and controlled observations by airport engineers were carried out immediately following the incident. Work was carried out yesterday evening to repair the temporary ramp and to ensure that the permanent pavement was not affected.

Additionally, the CIAA’s project team and the contractor met Monday night “to discuss and agree enhanced methodologies to be used in the construction of temporary ramps to prevent a reoccurrence throughout the remainder of the project”, the authority said.

In October 2019 the CIAA signed a $30 million deal to expand and upgrade the runway and airfield at ORIA. The selected bidder comprises two local companies — the Dart owned general contractor DECCO and Island Paving — along with IDL Projects, a Canadian firm that specialises in airport infrastructure.

“We had a slight set-back yesterday on flight operations but took immediate action to address the situation and to secure the runway, only resuming flight operations after safety inspections and controlled observations indicated it was safe to do so,” said CIAA CEO Albert Anderson. “I want to thank all teams involved in yesterday’s operations and last night’s works for their continued commitment to the highest standards of safety and operational excellence.”

The CIAA explained that the runway rehabilitation project entails the runway to be milled to a nominal depth of 25mm to remove the existing runway grooves, paint and rubber deposits, and then 180mm of hot mix asphalt will be placed on the runway in a series of three paving lifts.

At the end of each night’s production, a temporary asphalt ramp will be placed on the runway to account for the difference in the elevations of the new and existing pavement, and temporary paint striping will be installed. After the final lift of pavement is completed, the runway will be grooved and final markings placed.

Work on rehabilitating the runway began in early February 2020 and the CIAA says it will take approximately five months to complete. The work will require the runway to be closed nightly to all aircraft movements between the hours of 10:00pm and 7:00am.

    So much you know! I think you will find that the CAA has regulatory authority over the CIAA for all airport and aviation safety matters, including this issue, hence my query as to CAA’s/Richard Smith’s response. How about you get familiar with the facts?

    You absolutely right 7:57am CIAA must be listening to Larry Graham oh what a revelation? getting back to sinkholes 3 main causes two may not apply however when you interrupt or displace the flow of surface water you may cause water to find a new path which does cause sinkholes to form.Will they tell us if an EIA has been done for these natural ponds or shall we assume their only response is to remove the wildlife to make us feel good or make us believe they have done one?

      Those are not natural ponds. They were dug out to remove peat that caused excessive thermals under the approach path. I believe they were dug out in 1978 around the time of Tom Hubble’s crash.

    So what causes this aircraft blast and how come I for one have never heard of such a thing happening to the ORIA as long as it has been in operation? Ashpalt torn up from aircraft blast? Forgive me if i’m skeptical about that statement right after a major earthquake in our region. Keep your eyes and ears open people.

          Jet aircraft use the airport. A jet works by compressing and pushing back air from the engine – thrust – pushing the engine and the jet attached to it forward. Considerable thrust is needed to move the aircraft from a standing start to a velocity where the air movement over the wings will cause it to lift off the ground. The shorter the runway the more acceleration in a short distance is needed to achieve take off speed. To get that it is common practice for aircraft to stop at the end of the runway, apply brakes, then full throttle, maximising thrust, then release the brakes – bit like a sprinter straining against the blocks and waiting for the gun. That means there will be a huge amount of force in the displaced air pushed back from the engine to generate the thrust – the jet wash. The jet wash will scorch over whatever is immediately behind and below the engine – and the force is massive – consistent with the force need to propel an aircraft weighing nearly 100 tonnes fully fuelled into the air. Bit like your pressure washer can if not used carefully strip the paint off your house or your car rather than just clean it, the jet wash has huge force and its easy to see that it could peel a layer of asphalt that hadn’t hardened or bonded completely to the run way surface off – in just the same way that a pressure washer can peel off paint its cracked and not bonded properly to the underlying surface. Hope that helps.

      Just because you haven’t heard if it don’t mean this is a first. With only one runway in Cayman and it needing resurfacing it’s hard for little things like this not to happen as we have to keep using the runway the next morning after they paved it at night…

    • Anonymous says:

      You can’t be serious? When a plane takes off they power up the engines. This causes air to blast out of the rear of the engine to push the plane forward.

    In explaining the cause of the damage the CIAA has essentially revealed that, for some reason, the new tarmac on the runway didn’t stand up to expected jet blast. Could it be that the mix was incorrect (perhaps mixed to road standards instead of runway standards), or perhaps it was laid on an improperly prepared bed, or perhaps it was not allowed to cure properly before being exposed to flight operations.

    In any case, it seems like someone made a call to resume normal operations while the new surface was not fit for use. Will CIAA find out who, and take appropriate action? My guess is not and this is all we’ll hear about this!!

    Poor project management – again!! Where is Richard Smith MBE and his CAA with oversight over these kind of f**kups!!

      To 5.37pm See the comment at 4.47pm. The problem was not the permanent resurfacing; it was a temporary ramp ( meaning that it would be removed when the next adjoining strip is being paved ) used to taper off and leave no sharp edges between one layer and another like you see when roads are being paved but the work is incomplete.

    Kyd$30mln is over twice as much as the Usd$12mln that was originally forecast for MoBay Int’l Airport, the only other comparable IDL job in tropics, current redo ongoing til 2021 at some $60mln and counting. We already have an example of why it’s important to get professionals involved from the get-go. I don’t understand how this bid was awarded. Where are the bids published? Why can’t the public review financial contracts that concern them?

      Sounds like it was a temporary ramp to bridge two different levels of concrete – avoid a 90 degree edge between new concrete and old, given that they are doing the runway in stages rather than closing it whilst they do the whole thing as a single pour. You do that in concrete and removing the temporary ramp is a work in itself – stripping asphalt way easier – which of course is why it lifted under jet wash!
      Problem being the temporary ramp either hadn’t set or simply wasn’t up to the job.

      Genuine technical reason alright. Like putting temporary paving in place on a run way that won’t withstand jet blast. But like making an umbrella out of paper or repurposing a birthday ballon as a condom. Ever so slightly foreseeable that it’s fundamentally unfit for purpose and won’t work. Sorry if you think holding a professional to the standards of their profession and the necessary job is “hating”.

        My comment was aimed at the outrage machine that never turns off. Anything to do with the airport gets the same comments. This has become such a cynical, bitter, angry place to try to live. It’s like the River Styx, with untold souls moaning and wailing reaching to pull you and everyone else down into the soup with them. At this point we could set up a “Cayman Outrage Comment Generator”. Just load the last year’s worth of comments into it and let it rip. “Of course the runway isn’t strong enough for the golf carts from Britannia. Dart won’t buy lighter golf carts because McKeeva is too big for them and the CUC is too busy with its parrot amnesty! Standards in Public Life!!1111!!1 any word Governor Roper?!?!1!1!”

        Seriously people, shit happens, even to runways. When did we forget this?

        South Park said it best:

        Townsfolk: “Rabble rabble rabble rabble rabble rabble rabble!”

        Mayor: “Standing out here yelling ‘rabble rabble rabble’ isn’t going to help anything”

        Jimbo: “But we don’t know what else to do Mayor!”

        Townsfolk: “Rabble rabble rabble rabble rabble rabble rabble!”

        This is why the government ignores public opinion. Because we complain about EVERYTHING! Until the people of Cayman shut up for a while and get on with their lives, the government will never listen on any specific issue. They know they will be shouted down no matter what so they do as they please. Same thing with the public authorities: for a while they lived in fear of bad press, now they accept the inevitability of it and press on with their business. WE are a big part of the problem on this island. Let the airport be an airport, temporary asphalt ramps that need to be redone and all.

          I think you may be missing the bigger picture here…

          Imagine you were suddenly forced to pay $50k for a brand new car that was not only really worth $25k, but you saw the tires barely had any tread too… handicapped from the start.

          I feel this depicts what we got from the airport deal, albeit this is just from the general backlash I’ve heard and what I’ve seen within the short time it’s been open (flooding, overcrowding, dated design, still no jetways, etc…)

          The government and other ruling entities on this island have shown an extensive track list of disregarding/disrespecting the public’s needs, to take on overpriced AND under functioning projects that don’t contribute to our island the way they’re intended or portrayed (schools, port, etc…).

          They also move sneakily to ensure the money is spent and things are in place before the general public even knows what’s going on, so what can you do but complain?

          Don’t get me wrong, I’d have them out now if I could. Idk why we have to wait for 2021
