how to remove rubber depost from runways

In absence of required equipments and accessories as specified under ICAO mannuals. How RUBBER DEPOSIT from a portion of ASPHALT CONCRETE PAVEMENT FLEXIBLE RUNWAY OF PCN- 100 could be carried out economically. Any technological development in this specialised field for easy and economical removal of rubber deposit may kindly be informed.

The only aspalt concrete pavement flexible runway on my Cape Dory is the decking for the helipad, which we moved from the foredeck to the lazarette hatch cover (in order to simplify access to the cockpit, and avoid fumes from the aviation kerosine). Removal of rubber deposit has never been a problem - in fact, we like the rubber "patina" better than the look of freshly scrubbed aspalt concrete pavement.

On my CD 25 Dauntless we do not use any flexible runways. We have found that flexing of the runways leads to cracking of the underlying gel coat. For this reason we only pave our runways with rigid materials. However, in a related area we continue to have problems with the aircraft striking either the lower shrouds or the mast with their wings as they taxi to the foredeck. Any solutions out there?

After many years of wrestling with this problem, I gave up sold, my beloved CD27 "Nord Star" and traded up to a used 700' Essex class aircraft carrier. With the close of the cold war the cost of these babies on the used market are way down. (See Soundings data base) Admittedly haulout, preseason cleaning, and bottom painting do take a bit longer (a case of beer and a good friend or two will get you through it). The good news is that the rubber deposits clean up much quicker with the steel deck, windward performance is almost as good, and there is no longer the messy wing entaglement problem noted in the reply Jerry Hammernik.

One must recognize that all yacht design represents a compromise.
Although we would expect a seasoned expert like Carl Alberg would have factored rubber deopsits it into his thought process. (Surely Bayliner has done so.)
Those owners who fly only ultralights find the tire issue and firm deck requirementless of an issue. However I understand there have been embarrassing difficulty with short field take off performance under certain conditions.

I was about to remove this post as being off-topic, but obviously you guys have found a far better approach. I'm just going to dissolve a little of this sarcasm in some alcohol and use it to remove the diesel soot from my transom.

It'd probably also clean off the rubber real fine.

Nice work.

Actually, dissoving sarcasm in alcohol can be dangerous, because it is so caustic (the release of phlogiston from the gelcoat can be quite satirical, if not entirely ironic).
