Figure 3.4: Example of asset deterioration curve for roads showing how reoccurring, planned investments in adaptation and the preservation of assets during the initial degradation phase (e.g. from “excellent” to “good”) are significantly more cost-effective than reactive management through rehabilitation or reconstruction for conditions ranging from “fair” to “very poor”.
