Writing about road renewal
12 plain-language pieces for council engineers, asset managers and finance officers. Each one stands alone, says what PaveKeep does about the problem including what it cannot do, and lists its sources at the foot.

Knowing what you have
What a survey can and cannot tell you, what the numbers mean, and what to do about the roads nobody has looked at.

The budget argument
Making the case in the room where the road line competes with every other line.
Showing a council what a budget buys, and what the next one down costs
Condition charts do not win the budget argument. A scenario pair, with the roads named, is what changes it.

Defending the decision
What an auditor, a funding body or a councillor will ask for, and when to create it.
What a road asset management plan has to be able to prove
A plan is a document; what survives review is the evidence under it. The five things a reviewer reaches for.
