5. All the mechanisms, such as the conveyor, hopper gate, and auger, in the paver should be
working properly so as to maintain a good and consistent amount of HMA at the correct
temperature in front of the screed.
6. Ensure paving with a minimum number of transverse joints.
7. The reference point for screed operation should not be readjusted too much—avoid
constant/frequent readjustments of the paver’s automatic controls.
8. Use proper guidelines to select the correct rolling techniques—the types and number of
rollers, number of passes, and rolling pattern.
9. Make sure that the equipment, such as the paver and rollers, is in good operating
condition.
10. During laydown or rolling, if a problem is identified as a material- or mix design–related
problem, then it must be reported to the laboratory/plant as quickly as possible to ensure
readjustments/corrective actions.
The different factors, along with their associated problems, are listed in Table 16.1.
