Micro Surfacing Bitumen In Ireland
Micro surfacing bitumen in Ireland costs €520–€680 per tonne (Q1 2026, delivered), with polymer-modified cationic emulsifier grades (C60BP4, C65BP4) accounting for roughly 85% of road authority specifications. Typical application rates run 1.5–3.0 kg/m² of residual binder, meaning a single 20-tonne articulated load covers approximately 8,000–12,000 m² of carriageway. Lead times from continental European refineries to Irish ports average 5–9 working days, with Dublin Port and Cork handling the majority of imports.
What Is Micro Surfacing Bitumen?
Micro surfacing is a cold-applied, polymer-modified bitumen emulsion mixed on site with crushed aggregate, filler, water, and additives. It is laid by a purpose-built micro surfacing paver at 3–8 mm thickness and cures within 1–2 hours, allowing rapid reopening to traffic.
The bitumen component is not ordinary penetration-grade bitumen. It is a cationic emulsified bitumen, typically modified with 3–5% SBS or SBR polymer by weight of bitumen residue. This is what gives micro surfacing its rut-filling, skid-resistant, and surface-sealing properties.

Micro Surfacing Bitumen Supply in Ireland
Ireland has no domestic bitumen refining capacity. Every tonne of micro surfacing bitumen used on Irish roads is imported — primarily from refineries in the Netherlands, Belgium, Spain, France, and Poland. Imports arrive via Dublin, Cork, Waterford, and Rosslare, then move by bulk tanker to emulsion plants or directly to contractor depots.
| Route | Origin | Transit Time | Indicative Landed Cost (€/t) | Notes |
|---|---|---|---|---|
| Rotterdam → Dublin | Netherlands | 5–7 days | 520–560 | Highest volume, most stable |
| Antwerp → Cork | Belgium | 6–8 days | 530–575 | Strong for Munster projects |
| Bilbao → Waterford | Spain | 8–11 days | 545–590 | Polymer grades often ex-Spain |
| Gdańsk → Dublin | Poland | 9–12 days | 505–550 | Cost-competitive, longer lead |
| Le Havre → Rosslare | France | 6–9 days | 535–580 | Good for southeast schemes |
Key supply factors for Irish buyers:
- Brexit effect: UK-origin emulsion no longer moves freely; most Irish contractors shifted to direct EU supply post-2021.
- Seasonality: Demand peaks April–September. Winter orders often carry €20–€40/t premiums due to low plant utilisation.
- Minimum order: Most importers will not handle less than 20 tonnes (one full load).
- Storage: Emulsion must be kept above 5°C and used within 3–6 months of manufacture. Irish damp conditions make covered, heated storage essential.
Cost Breakdown and Pricing Factors
Micro surfacing bitumen pricing in Ireland is driven by four variables: base bitumen price (Brent-linked), polymer type, emulsion manufacturing cost, and haulage.
| Cost Component | Share | Indicative €/t |
|---|---|---|
| Base bitumen (pen grade) | 45–55% | 240–300 |
| Polymer modifier (SBS/SBR) | 10–15% | 60–90 |
| Emulsifier & additives | 5–8% | 30–45 |
| Manufacturing / blending | 8–12% | 45–65 |
| Packaging & haulage | 10–15% | 50–80 |
| Total delivered | 100% | 520–680 |
At a typical 2.0 kg/m² residual binder rate:
- Binder cost: €1.04–€1.36/m²
- Total micro surfacing cost (binder + aggregate + labour + plant): €3.50–€6.50/m²
Compare this with:
| Treatment | Cost (€/m²) | Design Life |
|---|---|---|
| Micro surfacing | 3.50–6.50 | 6–10 yrs |
| Slurry seal | 2.50–4.50 | 4–7 yrs |
| Hot rolled asphalt overlay | 12.00–20.00 | 10–15 yrs |
| Surface dressing | 1.80–3.20 | 4–7 yrs |
Micro surfacing sits in the mid-cost, high-durability bracket — the main reason Irish local authorities (e.g. Dún Laoghaire-Rathdown, Fingal, Cork County) have increased specification use since 2019.
Specification and Compliance for Irish Projects
Irish micro surfacing must comply with I.S. EN 12271 (surface treatment) and I.S. EN 13808 (bitumen emulsion specification). The Transport Infrastructure Ireland (TII) Roads and Bridges Standards reference these directly.
- Binder classification: C60BP4 = 60% residual binder, class 4 breaking, polymer-modified base.
- CE marking: Every drum or bulk delivery must carry a Declaration of Performance (DoP) under the Construction Products Regulation.
- Testing: Residual binder recovery per I.S. EN 1428, penetration at 25°C per I.S. EN 1426, softening point per I.S. EN 1427.
- Polymer verification: Elastic recovery test (I.S. EN 13398) must show ≥ 50% recovery for SBS-modified grades.
| Property | C60BP4 (Standard) | C65BP4 (High-Performance) |
|---|---|---|
| Residual binder | 60% | 65% |
| Polymer content | 3% SBS | 4–5% SBS |
| Softening point | ≥ 60°C | ≥ 65°C |
| Elastic recovery | ≥ 50% | ≥ 65% |
| Typical use | Rural roads, estates | Motorway shoulders, high-traffic |
| Price premium | baseline | +€35–€60/t |
For National Roads and Motorway schemes, TII increasingly favours C65BP4 to handle higher traffic volumes and Irish weather cycles.
Practical Considerations for Irish Buyers
Buying micro surfacing bitumen in Ireland is not a commodity purchase — it is a logistics-plus-specification decision.
What to check before ordering:
- Port of entry vs project location: Haulage from Dublin to Galway adds ~€35–€50/t; to Kerry, €50–€70/t.
- Emulsion age: Reject loads older than 90 days without re-testing.
- Temperature at delivery: Should be 60–80°C in bulk; below 50°C risks premature break.
- Batch consistency: Ask for the plant batch certificate, not just the marina test report.
- Weather windows: Micro surfacing requires surface temp ≥ 10°C and rising, no rain for 24 hours post-lay.
Bulk vs drummed:
| Format | Ideal Volume | Cost Delta | Handling |
|---|---|---|---|
| Bulk tanker | > 15 t | lowest | Requires heated storage |
| IBC (1,000 L) | 1–15 t | +€40–€60/t | Flexible, small schemes |
| Drums (200 L) | < 5 t | +€70–€100/t | High manual handling risk |
For most Irish county council term contracts, bulk tanker deliveries to a central depot remain the standard, with IBCs reserved for small or remote schemes.
FAQ: Micro Surfacing Bitumen in Ireland
How much does micro surfacing bitumen cost in Ireland?
Delivered emulsion prices range from €520 to €680 per tonne in Q1 2026, depending on polymer grade, origin, and haulage distance. C65BP4 premium grades sit at the top of that band, while standard C60BP4 from mainland Europe sits at the lower end.
Which bitumen grade is specified for Irish micro surfacing?
Most Irish schemes specify C60BP4 or C65BP4 cationic polymer-modified emulsion under I.S. EN 13808. TII national road projects increasingly require the C65BP4 grade for its higher softening point and elastic recovery.
How much area does one tonne of micro surfacing bitumen cover?
At a typical 2.0 kg/m² residual binder rate, one tonne of emulsion covers approximately 300–500 m², depending on aggregate gradation and existing surface texture. A 20-tonne load covers roughly 8,000–12,000 m².
What is the lead time for micro surfacing bitumen delivery to Ireland?
From order confirmation, expect 5–9 working days for continental European supply into Dublin or Cork, and 8–12 days for Spanish or Polish origins. Brexit has added 1–3 days to any routing via UK ports.
How long does micro surfacing last on Irish roads?
Properly specified and applied micro surfacing delivers 6–10 years of service life in Irish conditions, with high-polymer grades reaching the upper end. Resealing is typically scheduled at 7 years on county roads and 5–6 years on higher-traffic national routes.
