In short
Most common questions: repairs should be at least 25mm deep (ideally 50mm); a 20kg bag covers about 0.17 m² at 50mm (about 6 bags per m²); no tack coat is needed; it can go into standing water; and it carries a Lifetime Performance Guarantee.
Once the gap is cleaned out, what depth should it be?
Lay and compact a base course of sand and stone first. Typical asphalt work is 50mm deep, but with Asphalt in a Bag 25–30mm is usually enough.
Should the edge line be tidied up?
No — it isn’t necessary.
Should the length of the repair be rolled with a roller?
Yes. Roll it, crown it, then compact again so it is packed down hard. As with any cold asphalt, sharp points such as stiletto heels or walking sticks can mark the surface while it cures.
What warranty do you provide?
A Lifetime Performance Guarantee — as long as the pavement surrounding the repair stays intact, the repair should too.
What depth is ideal?
Minimum 25mm, ideally 50mm.
How much do I need?
One 20kg bag covers approx. 0.17 m² at 50mm deep — about 6 bags per m². A 1 tonne bulk bag covers about 8.7 m² at 50mm. Try the Asphalt Calculator.
Which grade of aggregate packs down more?
Rule of thumb: multiply the mix size by 2.5 for the minimum compacted depth and by 4 for the maximum. Mix 10, for example, compacts to between 25mm and 40mm.
What makes Asphalt in a Bag “GREEN”?
Asphalt in a Bag GREEN can contain recycled material, has ZERO VOCs and will NOT leach hydrocarbons.
What mixes and sizes is Asphalt in a Bag GREEN available in?
Mix 10 and Mix 7, plus Mix 5 on request (lead time required for manufacture). All are dense mixes unique to Asphalt in a Bag.
Why is a dense mix so important compared to open-graded mixes?
Density is one of the most important parameters in an asphalt mix. More fines mean fewer air voids between dust and stone, which stops air and water permeating the repair — often the difference between a repair that lasts and one that fails.
Can I include Asphalt in a Bag GREEN in green purchasing initiatives?
Yes. It is considered an Environmentally Preferable Purchase (EPP) and was the first product endorsed by the National Eco-Friendly Energy Council (USA).
Is it really GREEN, or is that green-washing?
The toxic solvents have been removed entirely — not just recycled asphalt added. The bags are recyclable plastic too.
How long does Asphalt in a Bag GREEN stay fresh?
12 months in a sealed bag.
Did you know? Volatile organic compounds (VOCs) are organic compounds that easily become vapours or gases.
