How to Set Up an Asphalt Paver Properly

Set Up an Asphalt Paver Properly

One of the most important aspects of setting up an Asphalt Paver is the proper placement of the screed. The screed should be about one-half-inch thick. Measure the thickness of the screed at each corner of the paver and make adjustments accordingly. If the screed is uneven on both sides, either the paver needs to be aligned more closely or the operator is pushing too hard with the nose.

Once the screed is set, the paver operator controls the paver truck and the transfer machine. They control the amount and width of material to be applied. They also tip the screed backward and forward to get the desired result. After applying the screed, the operator should level the base course.

Next, the operator should check the screed for level and damage. A level screed can help extend the life of the plates and runners. When the screed is out of level, it will cause premature wear on the plates and runners and will affect the quality of the asphalt mat. The following are some tips for proper screed placement:

Moreover, the asphalt mix should be at the proper temperature. Hot asphalt mix is more difficult to compact. The temperature of the mix must be just right to support the rollers behind the paver. Otherwise, it will become hard and brittle. The compaction process requires a larger roller than normal.

Once all the above is complete, the truck driver and the operator must communicate to place the paver in an ideal position. If the truck is too close to the paver, it could delay the process. Once all the necessary pieces are in place, the paver can start paving.

Proper machine preparation saves time and energy. The setup should be performed at the start of each day as well as at the end of the day. Proper screed setup can also save time and effort. The screed should be set properly according to the project specifications and it should be preheated to prevent sticking. The temperature range should be between 225oF and 275oC to avoid damage to the screed.

Another important step in the setup process is grade control. This is done manually or automatically. This control will determine how smooth the pavement is. The toe point of the screed arm determines the grade of the asphalt. The angle of the screed arm is also controlled by the toe point. It is important to note that a change of one inch in the tow point will cause 0.125 inches of variation in the leading edge of the screed.
