Roadbourne's graphene-enhanced cold-mix repair asphalt performs like hot mix — bagged, ready to use, and engineered for climates that destroy ordinary patches. Permanent pothole repairs. No downtime. No plant required.
Conventional asphalt must be produced at high temperature and placed immediately — tying repairs to batch plant availability, weather windows, and minimum order quantities.
Rain, frost, or low ambient temperatures halt traditional road repair. Patches fail within weeks when applied on wet surfaces — repeated call-backs drain budgets and credibility.
Heating asphalt to 160°C and transporting hot mix produces enormous CO₂ per tonne. Solvent-based cold patches emit VOCs and underperform — leading to rework and wasted material.
Roadbourne's material uses a graphene-enriched, plant-based binder (BioRoad SB) that activates at ambient temperature. Open a bag, fill the pothole, compact — done. Works on wet surfaces, in freezing conditions, and stores for up to 3 years.
Every product in the BioRoad range is built on the same graphene-enhanced, bio-based binder platform — independently certified and field-deployed across Europe.
The ready-to-use permanent repair solution. Graphene-enhanced binder activates at ambient temperature — open the bag, fill the pothole, compact, and open to traffic immediately. No plant, no heating, no waiting. Works from −20°C to +50°C, on wet or dry surfaces.
Liquid additive dosed directly at the asphalt plant. Reduces production temperature by 30–40°C versus conventional hot mix, cutting fuel costs and CO₂ emissions significantly. Enables higher RAP (reclaimed asphalt pavement) incorporation without sacrificing mix quality or workability.
Restores aged bitumen in reclaimed asphalt pavement (RAP), enabling up to 100% RAP incorporation in new asphalt production. Dramatically reduces virgin bitumen consumption and raw material cost — a circular economy solution for asphalt plants working with high RAP content.
The complete, factory-produced cold-mix repair asphalt — aggregate pre-blended with BioRoad SB binder and packed in 25 kg bags, ready to use with zero mixing required. Designed for road authorities, contractors, and distributors who stock repair material at depots or service vans for rapid deployment.
No specialist equipment, no weather dependency. Any crew can do it in minutes.
Order Roadbourne repair asphalt in 25 kg bags. Stock your depot or delivery van. No perishability concerns — the material is stable for up to 3 years in closed packaging.
Clear loose material from the pothole or crack. No drying required — the graphene binder works on damp or wet surfaces. Cut vertical edges on deeper defects for best adhesion.
Pour material into the defect, compact with a vibrating plate, roller, or vehicle tyres. Traffic-ready immediately. No curing time, no wait, no return visits.
Every specification is independently tested and documented. Ask us for the full technical dossier.
The graphene binder creates an amphiphilic bond — it displaces water at the aggregate surface rather than competing with it. This is the decisive advantage over solvent-based cold patches, which fail when applied damp.
Most cold patches fail below +5°C. Roadbourne material has been applied and compacted at −20°C in field trials. For road authorities facing winter backlogs, this eliminates the seasonal repair bottleneck entirely.
At 50% binder dose, the material remains workable for 36 months in sealed bags at ambient temperature. Road authorities can stock depots, councils can keep bags in vans, and retail distributors can hold inventory without refrigeration.
The binder is ~50% bio-content from recycled vegetable oils and olive mill waste. No solvents, no VOC emissions, no heating. Independently certified by CEMOSA. We provide the data sheet — not a marketing claim.
Our binder technology has been independently tested, deployed on motorways across Spain, Italy, Luxembourg, and the UK, and validated by major civil engineering groups.
Enter the dimensions of the repair area and we'll tell you how many 25 kg bags you need — no waste, no shortfall.
The calculator uses a compacted density of 2,000 kg/m³ and adds a 10% buffer for compaction and waste. Results are rounded up to the nearest full bag. One pallet holds 48 bags (1,200 kg).

Standard cold-mix uses petroleum solvent to keep the bitumen workable — the solvent evaporates after application, leaving a porous, weak matrix. Roadbourne uses a graphene-enhanced plant-based binder that creates true adhesion to aggregate, delivering 98% impermeability versus roughly 60% for solvent cold patch. The result is a permanent repair, not a temporary fill.
Yes. The graphene binder remains workable down to −20°C — validated in field trials in northern Spain and Luxembourg during winter maintenance seasons. Unlike solvent cold patch (minimum +5°C) or hot mix (minimum +10°C air and surface temperature), Roadbourne eliminates the seasonal shutdown that plagues road authorities in cold climates.
No specialist equipment required. Pour the material into the defect, compact using a vibrating plate compactor, a roller, or even vehicle tyres. The repair is traffic-ready immediately. No primer coat, no tack coat, no heating equipment. A crew of two can complete dozens of pothole repairs in a standard shift using a van and a plate compactor.
With proper compaction, Roadbourne repairs are designed to be permanent — not temporary patches pending full resurfacing. The 98% impermeability prevents water ingress, and the graphene binder resists the shear and fatigue cycles that cause conventional patches to ravel and pop out. Independent trial data from motorway sections in Italy and Spain show performance comparable to hot-mix overlays.
Roadbourne works with regional distributors, road contractors, and local government supply agreements. We can supply bagged product (25 kg) ex-factory from our European production sites, or work with local partners on private-label arrangements for specific markets. Our franchise model allows partners to build a local road-repair business using Roadbourne technology with full technical and commercial support.
We are actively expanding. Current production is based in Europe (Italy + Spain) with distribution capability across Europe and active discussions for markets in Eastern Europe, Southeast Asia, and the Middle East. If you are interested in a regional partnership or distribution agreement, use the contact form and we will respond within one business day.
Whether you're a road contractor, local authority, or distributor — we respond to every inquiry within one business day.
