A durable surface starts below the asphalt.
Ground, levels and drainage
Before mobilisation, confirm ground conditions, design loading, connection levels and a reliable stormwater route. These factors matter more to service life than the visible asphalt layer.
- survey and existing utilities
- bearing capacity and moisture
- longitudinal and cross falls
- ditches, culverts, inlets or stormwater network
Formation and bearing layers
Weak ground is replaced or stabilised and materials are placed in controlled layers. The next layer should not conceal an untested or saturated base.
- excavation and preparation
- frost-resistant and aggregate layers
- grading and compaction control
- protection of chambers, culverts and utilities
Kerbs, surfacing and connections
Kerbs establish geometry and levels. Asphalt follows base acceptance, a weather check and coordinated material deliveries.
- kerb lines and accessible crossings
- bond coat and asphalt placement
- chamber and existing-surface connections
- shoulders, markings and final reinstatement
What to send for pricing
Provide a plan with areas and lengths, pavement layers, scope limits, location and programme. If no design exists yet, BIMARKS can begin with photographs, approximate dimensions and a site visit.
