Asphalt Paver

What is Asphalt Paver?

Asphalt Paver, A self propelled machine that lays hot mix asphalt evenly and at controlled thickness on roads and lots.

Description

An asphalt paver, also called a paving machine, receives hot mix asphalt from dump trucks, conveys it to a screed, and spreads it at the desired width and thickness. Hydraulic augers distribute material ahead of the screed, which levels and partially compacts the mat before rollers finish densification. Pavers range from 8-foot commercial models to 30-foot highway machines, with automatic grade and slope controllers for smooth surfaces. Proper preheat, consistent speed, and continuous feed prevent segregation and cold joints.

FAQs

  • What powers an asphalt paver?

    Diesel engines drive conveyors, augers, and propulsion tracks.

  • How wide can pavers lay asphalt?

    Extendable screeds reach 30 feet on highway models.

  • What is the function of the screed?

    It levels, profiles, and initially compacts the asphalt mat.

  • Are pavers tracked or wheeled?

    Large highway pavers use crawler tracks; small units may be wheeled.

  • How is the mat thickness controlled?

    Automatic grade sensors adjust the screed angle of attack.

  • Who operates asphalt pavers?

    Trained paving crews with separate screed operators.

  • What maintenance is critical?

    Daily cleaning to prevent asphalt buildup on conveyors and screed plates.

Fun Fact

Fun Fact: The first mechanical asphalt paver was developed in 1931 by Barber Greene, revolutionizing modern highway construction.
