The DD 60 series is a well-known range of asphalt rollers from the Volvo Group, used predominantly in construction and roadwork for compacting asphalt, soil, and other materials. These rollers are valued for their reliability, durability, and versatility. However, like all machinery, understanding the common issues and maintenance practices can help operators maintain efficiency and minimize downtime.
In this article, we’ll take a detailed look at the DD 60 series asphalt roller, its features, common problems, and maintenance practices to ensure optimal performance.
Overview of the DD 60 Series Asphalt Roller
The Volvo DD 60 series are articulated tandem rollers, designed to meet the needs of road construction, maintenance, and asphalt laying. They are particularly effective for tasks like:
Key Features
While Volvo's DD 60 series rollers are built for tough conditions, there are some common issues that operators may encounter. Understanding these problems and knowing how to troubleshoot them is essential to keeping the machine running smoothly.
1. Vibration Problems
One of the most significant features of the DD 60 is its vibration system, which provides the force necessary for compacting materials. However, issues with vibration can occur, particularly when the system is overused or not properly maintained.
Engine-related issues can arise, especially in older models or when the machine is heavily used. Common problems include poor power output, stalling, or difficulty starting.
As with most heavy equipment, hydraulic system issues can cause the roller to operate inefficiently or not at all. The DD 60 relies heavily on hydraulics for various operations, such as the vibration mechanism and steering.
Over time, the tires and roller drums of the DD 60 series can wear out, particularly when used on rough or abrasive surfaces. This wear can result in reduced compaction efficiency or uneven compaction.
The electrical system in a DD 60 series roller can encounter faults that prevent certain functions from working. This could be anything from lighting problems to issues with the machine’s electronic control systems.
Preventive maintenance is key to keeping the DD 60 series running efficiently. Below are some general tips for troubleshooting and maintaining the roller:
1. Regularly Inspect the Hydraulic System
The hydraulic system is a critical part of the DD 60’s function. Ensure that the hydraulic oil is changed according to the manufacturer’s schedule, and always monitor for leaks or signs of wear in the hydraulic hoses. Pay particular attention to the vibration motor and steering system.
2. Perform Regular Engine Checks
Regular engine maintenance is essential to avoid performance issues. Check the air filters, fuel filters, and oil levels, and change the oil as needed. Inspect the fuel system for leaks and replace any worn-out components such as fuel lines or fuel injectors.
3. Monitor Tire Pressure
Correct tire pressure ensures optimal performance and reduces uneven wear. Overinflated or underinflated tires can affect the roller’s operation and lead to unnecessary repairs. Check tire pressure regularly and adjust as needed.
4. Inspect Electrical Components
Check all electrical connections regularly, especially if you notice issues with the machine’s electronics or control systems. Ensure that the battery is charged and that there are no corroded or loose wires that could cause electrical failures.
5. Address Vibration Issues Early
If you notice any irregularities in the vibration system, address them immediately. Vibration failure is one of the most common issues that can affect a DD 60 series roller. Regularly check the vibration motor and control systems to ensure they are functioning correctly.
Conclusion
The Volvo DD 60 series is a robust and reliable asphalt roller, ideal for a wide range of construction and compaction tasks. While these machines are designed to withstand heavy use, they are not immune to issues like vibration failure, hydraulic problems, and engine performance issues. By staying proactive with regular maintenance and addressing issues as soon as they arise, operators can extend the life of their equipment and avoid costly downtime.
Understanding the common issues, proper troubleshooting methods, and best practices for maintenance can make a significant difference in the longevity and performance of your Volvo DD 60 series roller.

While Volvo's DD 60 series rollers are built for tough conditions, there are some common issues that operators may encounter. Understanding these problems and knowing how to troubleshoot them is essential to keeping the machine running smoothly.
1. Vibration Problems
One of the most significant features of the DD 60 is its vibration system, which provides the force necessary for compacting materials. However, issues with vibration can occur, particularly when the system is overused or not properly maintained.
- Symptoms: Lack of vibration, inconsistent vibration, or the roller fails to engage vibration when operating.
- Common Causes:
- Low hydraulic fluid levels or contamination in the system.
- Faulty vibration motor or a worn-out roller drum.
- Hydraulic valve failure or misadjustment.
- Low hydraulic fluid levels or contamination in the system.
- Action:
- Regularly check and replace hydraulic fluid.
- Inspect vibration motors and components for wear.
- Ensure proper calibration of the vibration system.
- Regularly check and replace hydraulic fluid.
