Асфальтоукладчики (asphalt pavers) are the workhorses of road construction. They receive hot mix asphalt from trucks and spread it evenly on the road surface. Modern pavers come in various sizes, from small units for minor repairs to large tracked or wheeled machines for highway construction. Key features include automated grade and slope control, which ensures a smooth and consistent surface. Brands like Caterpillar, Volvo, and Dynapac are leaders in this field, offering models with advanced technologies such as GPS guidance and telematics for real-time monitoring.

Катки (rollers) are used to compact the asphalt after it has been laid by the paver. Compaction is crucial for achieving the desired density and durability of the road. There are different types of rollers, including vibratory rollers, pneumatic tired rollers, and combination rollers. The choice of roller depends on factors like the type of asphalt mix and the project specifications. For instance, vibratory rollers are highly effective for initial compaction, while pneumatic rollers provide a smooth finish.

Вспомогательное оборудование, such as material transfer vehicles (MTVs) and feeders, helps in maintaining a continuous supply of asphalt to the paver. This reduces delays and ensures that the paving process is uninterrupted, which is vital for quality control. Additionally, thermal profiling systems and infrared cameras are used to monitor the temperature of the asphalt, preventing issues like premature cooling that can lead to poor compaction.

Innovations in paving equipment have led to the development of high-tech machines that integrate with digital systems. For example, some pavers now feature automated control systems that adjust the paving parameters based on real-time data, reducing human error and improving accuracy. This not only enhances efficiency but also contributes to longer-lasting road surfaces.
