- Traffic impact
- No lane closures
The challenge & transformation
Ride quality and rutting drive maintenance budgets, and neither can be argued from a visual inspection. A windscreen survey produces a view rather than a measurement, so a programme built on it cannot be defended to a treasurer or an auditor. Roughness governs what road users experience and what vehicles cost to run, yet most networks carry no current figure for it, and wheel-path deformation develops almost invisibly until it is holding water.
Solid-state LiDAR profiles the surface continuously along the full length at traffic speed, returning engineering metrics rather than imagery to interpret. Longitudinal profile yields roughness indices such as IRI, transverse profile yields rut depth, and texture is measured alongside both from the same pass. Successive surveys run to the same specification and chainage, so rate of change becomes an input to the programme and coverage stops being a decision about which lengths to sample.

Continuous measurement of the surface itself, scored into the indices a rehabilitation programme is argued from.
Pavement condition assessment (PCA)
Raw profile converted into standard engineering metrics and objective condition scores, so deterioration can be modelled and rehabilitation prioritised.
- IRI roughness and Pavement Condition Index scoring
- Section-by-section ranking for a rehabilitation programme
- Every score traceable to the metrics that produced it
- Acceptance reporting on new pavement against a specified tolerance
Roughness, rutting & texture
The three measurements the indices are built from, all taken on the same run rather than sampled by hand.
- Longitudinal profile and roughness indices such as IRI
- Transverse profile and wheel-path rut depth
- Surface texture measured alongside both
- Engineering metrics rather than imagery to interpret
Network survey & deterioration trends
The whole network measured from a moving vehicle on a fixed cycle, with each cycle run to the same specification and chainage as the last.
- Full-length measurement at traffic speed, with no lane closures
- Coverage no longer a decision about which lengths to sample
- Cycles differenced to give rate of change, not present state alone
- Post-event lengths compared against the previous cycle

The industries this work is commissioned in, and what a measured surface changes in each.
Measured condition across a local authority network, so maintenance spend follows deterioration rather than complaint volume.
Roughness, rutting and texture across highway concessions and major routes, scored for programme and contract acceptance.
Surface condition on estate haulage roads, where a deteriorating route costs vehicle wear and delayed crop movement.
Post-flood and post-landslip surface assessment, differenced against the previous cycle to quantify what the event did.
Access road condition through reserves and catchments, measured without repeated vehicle movements over sensitive ground.
Ride quality and surface condition on the approach roads that response and supply routes depend on.
