| 摘要： | A have improved considerably in recent years. Manufacturers have made their equipment more efficient and more productive, as well as boosting the finish quality of the mat being paved. Powered by the latest generation engines, new pavers are more fuel-efficient and more productive, while producing lower levels of emissions. Visibility over the hopper and screed have been improved, while control stations have become more ergonomic. The use of systems to draw asphalt fumes away from the screed and hopper and vent these through high-placed exhaust systems have made the machines more pleasant to work on for long periods, in addition to the quieter and smoother operation. Machine control technology is now available from all the main players in this segment, allowing contractors to include the paver as part of the BIM process. Design models can be used as the basis for operating programs for the pavers, ensuring an accurate outcome. Software can also integrate the paver into the material logistics and supply chain, with asphalt quality assured and tracked from the plant, through delivery by truck until it arrives at the paver. The machine control technology can be used to monitor compaction at the screed as well as monitoring the thermal profile of the mat. Using material transfer vehicles can also help to ensure both material and heat segregation is virtually eliminated from the mat. |
