Overview

Compaction Meter Value is an accelerometer based system that provides an indication of material stiffness. The system is available on smooth drum vibratory soil compactors and tandem vibratory asphalt compactors. It measures only when the vibratory system is active, and provides a unitless value calculation derived from the recorded data that indicates composite stiffness.

Compaction Meter Value has an optional Mapping system, which helps the operator visualize the work as it occurs, ensures that the compactor covers the entire jobsite and produces uniform work. It can also indicate problem areas allowing remediation to occur while the ground is open at a lower cost. Mapping documents the work and provides data for analysis. SBAS or RTK systems are offered depending on accuracy needs and available infrastructure. Initial investment can be scaled up to meet job-specific needs.

Connectivity, an optional machine to machine communication system, helps sync rolling patterns by sharing coverage and pass-count maps between the operating displays of multiple machines. Ideal for use when performing echelon compaction, operators can monitor areas of coverage and the number of passes made via a color display. If a trailing operator sees an area of missed coverage, they can easily pick it up to ensure the entire rolling pattern gets the attention that is needed. System records temperature and passes for future analysis and documentation.

FOR SOIL APPLICATIONS: For smooth drum compactors only. It is capable of measuring from 1 to 1.2 m ( 3.3 - 4 ft) deep depending on site conditions and is suitable for use on granular soils. Not recommended on cohesive soils.

FOR ASPHALT APPLICATIONS utilizes drum-mounted accelerometers to measure and record composite stiffness of the asphalt layer, base layer, and sub-base material.

Consistent quality

  • Helps the operator produce uniform compaction. On asphalt applications, can help indicate base structure health.
  • Mapping correlates compaction measurements to location they were taken, allowing the operator to visually monitor progress, identify trouble spots, ensure coverage and uniformity

Optimizes efficiency

  • Empowers operator to determine when compaction meets target value and move on to the next job preventing unnecessary passes
  • Measures only when vibratory system is active
  • Provides indications of soil stiffness
  • CMV (Compaction Meter Value) is accelerometer-based
  • Measures deep: 1 to 1.2 m (3.3 to 4 ft), depending on materials
  • Mapping keeps track of pass counts and coverage while providing real time maps of compaction work

Applications and machine types

  • Suitable for granular applications
  • For use on smooth drum (CS) machines only
