{"product_id":"road-works","title":"Road Works","description":"\u003cp\u003eA road is the one piece of engineering that passes judgement on itself in public: a wrong gradient is seen in a puddle, missing compaction is seen in a settlement, and a poor mix is seen in cracking after one summer. And all of it goes back to numbers that were calculated, or were not, before the first truck arrived. The road cross-section and the design controls, horizontal alignment with curve radius superelevation and sight distance, vertical alignment and crest curves, earthworks by the end-area method and the subgrade by California bearing ratio, pavement layers by the structural number, compaction and lot acceptance, asphalt as a mix and as an operation and as a quantity, kerbs and surface drainage, then the take-off per kilometre and handover. 10 fully worked examples, every number checked.
