What are the impacts of the intensification and diversification of agricultural production on rural roads?
Minor roads of minimal pavement construction have to accommodate relatively large volumes of traffic, particularly commercial vehicles.
What are some of the challenges facing engineers in road maintenance?
Maintaining a network of roads within available budgets, inadequate standards of roads, increasing traffic volumes and axle loadings, decreasing budgets, and the expectation of further cuts in public expenditure.
Why is it essential for different aspects of road maintenance work to integrate smoothly?
To achieve a good standard of effective maintenance.
How has the growth of towns and cities impacted urban roads?
Areas serviced by minor roads now carry heavy volumes of traffic.
What is the goal of road maintenance in terms of available budgets?
To maintain a network of roads within available budgets.
What makes the task of maintaining roads difficult?
The amounts of roads built to inadequate standards, the increase in traffic volumes and axle loadings, decreasing budgets, and the expectation of further cuts in public expenditure.
What is the goal of road maintenance?
To preserve the asset, not to upgrade it
How is road maintenance categorized for management and operational convenience?
As routine, periodic, and urgent
What is the purpose of routine maintenance?
To ensure the daily passability and safety of existing roads in the short-run and to prevent premature deterioration
What are some typical activities included in routine maintenance?
Roadside verge clearing, grass cutting, cleaning of silted ditches and culverts, patching, pothole repair, inspection and repair of signs, markings, and traffic control devices
What does preventive maintenance aim to do?
Preserve the structural integrity of the road
How often is repaving needed for a paved road?
About every eight years
What is the frequency of routine maintenance activities?
Once or more a week or month
What are some examples of periodic maintenance activities?
Preventive, resurfacing, overlay, and pavement reconstruction
What is the cost comparison between routine and periodic maintenance works?
Periodic maintenance works cost more than routine maintenance works
What are the categories of road maintenance for management and operational convenience?
Routine, periodic, and urgent
