Study Notes
Pavement Management
- A small hole in a cloth, if not repaired, will eventually tear it asunder; similarly, a roadway will deteriorate if its surface is not maintained, leading to more serious problems and higher costs.
Importance of Timely Repair and Rehabilitation
- Lack of funds often limits timely repair and rehabilitation of transportation facilities, leading to a greater problem with more serious pavement defects and higher costs.
- Inadequate funds and personnel force transportation agencies to balance their work program between preventive maintenance activities and projects requiring immediate corrective action.
Consequences of Neglected Maintenance
- Neglected preventive maintenance leads to road deterioration, with rehabilitation based on user complaints.
- Poor-quality pavements cause vibration, severe damage to vehicles, and may lead to crashes, increasing user costs.
Ideal Approach to Pavement Management
- Ideally, preventive maintenance should be carried out in an orderly and systematic way, being the least expensive approach in the long run.
Approaches to Pavement Management
- The "squeaky wheel" approach selects projects based on Greatest attention.
- A regular schedule-based approach repairs all roads, regardless of funds availability.
- Realistic strategies establish minimum standards for acceptable pavement condition and require treatment to maintain a minimum level of serviceability.
Pavement Management Strategies
- Consideration of pavement condition, first cost, annual maintenance, user costs, and various constraints (safety, physical, environmental, and economic) are part of rehabilitation management strategies.
- Life-cycle cost analysis is the basis for pavement management, including initial construction, routine maintenance, and major rehabilitation activities over the pavement's lifetime.
Pavement Management Process
- A systematic process for maintaining, upgrading, and operating physical pavement assets in a cost-effective manner.
- Combines established engineering principles with sound business practices and economic theory for organized and scientific decision making.
- Steps involved: (1) assess present pavement condition, (2) predict future condition, (3) conduct an alternatives analysis, and (4) select an appropriate rehabilitation strategy.
Pavement Management System
- A computer-driven protocol consisting of:
- An inventory and condition database
- Mathematical models to forecast future pavement condition
- Procedures for conducting alternative analyses
- Reporting and visualization tools for interpreting and displaying results
Levels of Pavement Management
- Two levels: network level and project level, as illustrated in Figure 21.1.
