Pavement Type Selection
In making any decision concerning the type of pavement to use on a roadway, a road agency is obligated to get the best value for the taxpayers.
Some promoters would argue that the agency should determine pavement type on the basis of whether a particular industry “needs the work.” The APA’s response is that the pavement type selection process should be used to select the best possible pavement type for a given road – in other words, it should be a road user-oriented process, not an industry-oriented process.
In order to deliver the best value for taxpayers and road users, the system used to select pavement type should be:
- Based on historical records
- Primarily driven by economics
- Periodically reviewed
Asphalt pavements possess many advantages in. Among these are:
- Low initial cost
- Low maintenance costs
- Flexibility and speed of construction
- The ability to handle heavy loads
- Long life
- Complete recyclability
- Environmental, social, and economic sustainability
Furthermore, asphalt pavements allow an opportunity to reduce traffic noise at the source and improve ride quality. These are a few of the reasons that asphalt pavements should be considered in every pavement type decision.
