It usually does not happen by accident when you have successful asphalt paving projects. They are all the outcomes of careful planning and preparation that is appropriate. There will be a greater level of imp-action resulting to the other level differing from the usual paver set up to achieve the optimum mat temperature for rolling at the correct time for each of the steps that are involved in asphalt paving.
It can well mean a great difference between attaining a bonus and being delayed with the attention to the details that run throughout the process and these all start with a great paver set up.
- Proper paver setup for a smoother pavement
It becomes a lot more important for the inspection of the paving machine to be done whilst its components for looking out for issues that can effectively affect the operations of paving. You need to check all the gauges while starting up with the asphalt paver.
When you rotate the depth cranking up or down to the desired path of paving with the established screed-plate angle the depth takes place. With the mat thickness hat is around will result in the increase and the decrease of the angle of the screed.
The mat depth is established through a project engineered determining the estimated usage and the volume of the traffic that is intended for the pavements. The crew must especially focus on the factors that will be yielding the best quality pavement.
- Laying a quality mat
For determining the pavement quality, both material level and the paver speed plays a huge role. It is all about the consistency, consistent head of material in front of the screed present and the speed for consistent paving are the two most important factors established for laying a quality mat.
- Maintaining an adequate head of material
It is all due to the improper head of the material that is in front of the screed with more than 95 percent of the material faults in asphalt paving. Maintaining the width of the screed, the head of the material is what belongs to the mass of paving for the mix that lies directly in front.
If there are a greater number of fluctuations during an ongoing paving job then it becomes completely impossible to produce a leveled and a smoother pavement surface.
There is also a decrease the causes of the reduction of the mat thickness and causes great flaws with the increase in the head of material. When the head of material is concerned it should be of constant nature ranging widely across the screen.
- Paving speed
When the paving speed does not remain constant then the ripples, waves, and irregular mat depth can occur. The paver will also operate nonstop throughout the day due to the change in paving speed that can affect the ability to lay a uniform mat in an ideal paving operation.
- Compacting the different way
Temperature monitoring for the mat is the first rule that needs to be followed. Compaction must be accomplished while the mix has enough fluidity to allow aggregate particle movement in order to remove voids and excess air in the pavement structure. In some instances, the time available for compaction can be limited to 10 minutes.
The cooling of hot mix asphalt is predictable and can be anticipated based on prior experience and current ambient conditions. A compactor operator should keep notes on projects and different types of materials to determine the best temperatures. Once this is set, it’s important to work in that zone all day.

- Rolling pattern
Maintaining a precise rolling pattern is the final, and especially crucial, step in the road building process. It determines road smoothness and contributes to the long-term stability of the road. It’s essential to complete rolling before the mix temperature drops too low to achieve target density.
This practice allows the highest production to be achieved and, for mixes exhibiting tenderness, proper breakdown rolling density can be reached before the mix becomes unstable or develops a tender zone.
- Intelligent Compaction
Intelligent Compaction (IC) has gained momentum in the industry over the last decade, and for good reason. IC technology allows for better record keeping, increased compaction uniformity, automation and increased productivity for road crews that ultimately saves time.
However, previous IC systems were missing an exact density measurement, data critical to the integrity of the finished road, and more accurate measurement than mat stiffness alone.
- Training
To learn more about operation and safety, training programs from manufacturers can be a valuable tool. For example, Volvo Road Institute conducts courses by professional instructors who are focused on helping paving contractors and those in the paving industry maximize productivity through various paving and compaction best practices, as well as machine performance and maintenance.
