adding lip to tarmac

[fred]

we have a gutter that a down spout discharges into It. Unfortunately it is slightly lower than the surrounding drive so lots of crud and leaves get washed into it. I've tried using a gutter shield like this

but it was only partial success. I'd like to build a little ring around it, about 50mm high but wonder if a tarmac repair kit would work. Would it bond to the existing tarmac? Any alternative suggestions would be welcomed

A rubber strip, like a mini speed bump? Build a up with a repeated run of melted bitumen (as used in some road joints and cracks)?

You can get liquid bitumen:

something could be done with roofing felt, perhaps.

Although if the OP wants it to be one piece with existing tarmac I would probably be thinking of more tarmac. You can get it in small bags:

Has anyone tried "rejuvenating" that stuff?

I have about 3/4 of a bag several years old, a GBFO gas burner and could organise a metal sheet to cook it on, if there's any hope it would become workable ...

[Theo]

I've never used that stuff, but I'd guess it hardens by losing volatile hydrocarbons, since it's designed for cold laying. Perhaps it needs a solvent of some kind?

Datasheet:

it contains 'flux oil', and composition has 0.7-1.8% 'Hydrocarbons, C15-C20, n-alkanes, isoalkanes, cyclics, < 0.03% aromatics' Perhaps mixing a bit of paraffin or diesel?

Heating it might drive off the remaining volatiles and make it harder?

I've seen utility companies sloshing a bit of diesel on it, but never sure if that was to prevent it sticking to tamping tools etc.

Would that not be a trip hazard though? Depends if its in a place where you might put a foot. Brian

Why not just seal around the base of your exiting drain cover?

A one brick high wall the same size as the base of the drain cover?

[Fredxx]

I think that would look strange.

Why not make a feature, and use bricks on top of the Tarmac stuck together and to the tarmac to create the raised drain?

[alan_m]

The photo in the original post shows what is described is a gutter cover is actually a 1 foot x 1 foot drain cover fitted to the bottom of the gutter down pipe and covering the drain.

[fred]

Thats a great idea. I had toyed with the idea of a small concrete kerb but was unsure how to seal it. Many thanks

[fred]

It depends what part of the country you live in. In some places a down pipe is known as spouting, gutters are known as shores etc.etc.

Why not just get another gully, the fired clay type are usually flat underneath with just a spigot poking through. Sit it on top of the existing gully, that will provide a lip.
