Hot Mix Asphalt Strain Gages

REPEATABILITY OF ASPHALT STRAIN

perpetual pavements in July 2005. Sixteen asphalt strain gauges were placed at the bottom of the hot-mix asphalt (HMA) layer of these structures. Six rounds of measurements were taken to determine the variability of the strain gauges. Thirty to variability was found in gauges with the same offset relative to the

Strain AE Sensor Description. An sensor measures hot-mix asphalt strain response due to dynamic loads. The Angled Asphalt Strain (AE) sensor is an electrical resistance (full bridge) strain transducer, utilizing a nylon rod with transverse steel

Short- And Long-Term Evaluation Of Asphalt Concrete

Short- and Long-Term Evaluation of Asphalt Concrete Strain Gauge Installation Methods Applied to the KHCTR. In the present study, three strain gauge installation methods (mound, trench-cut, and block-out) are evaluated to propose a set of methods that are appropriate for different layers of hot mix asphalt (HMA)

Evaluating The Longitudinal And The Transverse Horizontal

Horizontal strain at the bottom of asphalt concrete due to repeated traffic loads is the most critical parameter in characterizing fatigue performance of flexible pavement. The study of horizontal strain is thus very important to understand the strain behavior, predict the fatigue life and implement in design and analysis. A total of twelve Horizontal Asphalt Strain Gages (HASGs), six gages
