摘要： A material testing apparatus includes an actuator to apply a force to a load head according to electronic control signals. The load head supplies a load to a material specimen in a first dimension. A plurality of load line displacement (LLD) reference points extend radially outward from the load head; and a plurality of LLD measuring devices correspond to the plurality of LLD reference points. Each LLD measuring device is positioned to detect a position of a corresponding LLD reference point along the first dimension and is configured to transmit position signals to a controller programmed to perform a performance test on the material specimen using feedback control based on a combination of the position signals, including an average of the position signals.

摘要： The use of recycled materials can have significant economic value. With the increasing quantity of recycled material used in viscoelastic materials, especially asphalt mixture, understanding how they interact with original materials to produce a mixture that performs successfully, becomes critical. Currently, the technology to determine the effect of additives on the performance of asphalt mixture is lacking. The present invention relates to a new unified methodology for mechanical testing of asphalt mixture and other viscoelastic materials that improves the current practice in speed, convenience, and accuracy. A new improved specimen mounting method on Dynamic Shear Rheometer (DSR), a new recovery method for fine portion of asphalt mixture, and three new tests for the performance of recovered material using DSR is disclosed. The new methods provide performance grading of asphalt mixtures that is new to the industry and provide necessary tools for determining the effect of recycled materials on performance.

摘要： A system for preventing the evaporation of liquids from tack coat by sealing the testing pad inside an enclosure immediately after the tack coat is applied comprising a sealed enclosure and testing pad. The weight of the testing pad before and after tack coat application is used to calculate the calibration rate of the tack coat. Thus, by sealing the liquids inside the enclosure, the proper second weight of the testing pad is obtained resulting in an accurate calibration rate and application of tack coat on asphalt. The system further includes affixing a weighted material to the testing pad prior to placing the testing pad on asphalt and spraying the tack coat during asphalt calibration to remove the need to tape the testing pad and prevent shrinkage and movement of the testing pad during application of the tack coat.
