Assessment of Fracture Resistance of Asphalt Overlays through Heavy Vehicle Simulator and Laboratory Testing: Synthetic Fiber and Rubber Modified SMA Mixes
… (PCCP) conducted at the Virginia APT facility. A Heavy Vehicle Simulator (HVS) was used to compare the reflective cracking performance of a Stone Matrix Asphalt (SMA) control mix with a modified mix with a synthetic fiber. The discussion includes the characterization of the asphalt mixes, the …

Enhancement of Network Level Macrotexture Measurement Practices through Deterioration Modeling and Comparison of Measurement Devices for Integration into Pavement Management Systems
… when subjected to traffic loading using a heavy vehicle simulator to report the effect on pavement macrotexture. The second experiment compared high-speed macrotexture measurement devices on a variety of surfaces and under various operating conditions. The change in macrotexture due to …

Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide
… testing of two flexible pavements with the Heavy Vehicle Simulator (HVS), specimen production, laboratory testing of materials, and calculation of permanent deformations using the M-E PDG software v0.910. Field calibration factors were assessed in order to match the model’s results with the …

Performance Analysis and Modeling of Pavements with a Cold Central Plant Recycled Base under Accelerated Loading Testing
… gauges, pressure cells, and thermocouples. A heavy vehicle simulator (HVS) was used to load three replicate test sections in each lane, with the temperature controlled at 39°C at a depth of 1.5 inches. Results from the instrument verification analysis showed that the strain gauges and pressure …

Moisture effects on the mechanical behavior of flexible pavement subgrades
… subjected to accelerated traffic by means of a heavy vehicle simulator. The test results were analyzed and relationships between subgrade soil type, moisture content, load intensity and number of traffic repetitions to failure were established. The effects of subgrade soil moisture content on …
