This training course discusses the different types of asphalt roads, presents various methods of building and maintaining asphalt roads, and describes the types of surface distress that are common in asphalt roads. Guidance is given to help decide what action should be taken to fix an old asphalt road, how to build a new asphalt road, and how traffic may affect which actions will be most effective. This course is intended to assist agencies with the cost-effective maintenance of asphalt roads. Although the course addresses numerous pavement types and conditions, there may be instances when additional information is needed. Such information may be found in the reference list at the end of each module, or from the local Technology Transfer (T2) centers. |
