摘要： The disclosure relates to asphalt foam collapse test methods and related apparatus for the measurement and determination of foamed asphalt binder quality, in particular warm-mix asphalt. Various asphalt binder/foam quality indicators can be measured according to the disclosure, such as bubble size distribution, bubble surface area, foam expansion ratio, foam half-life, foam index, as well as normalized parameters related to the same. The disclosed methods and apparatus permit the repeatable characterization and formation of foamed asphalt compositions, enabling the skilled artisan to form foamed asphalt/aggregate compositions of known, repeatable quality. This enhances the ability to form WMA foamed asphalt concrete with controlled and favorable properties selected for the particular environmental conditions (e.g., climate-, weather-, and/or traffic-related) where the concrete is to be used.

摘要： The present invention is capable of inspecting with high accuracy the shape of a road travel surface when travelling at a low speed, and even when acceleration, deceleration, or stoppages occur frequently, and generates a highly reproducible road surface longitudinal profile. A photograph is taken along the longitudinal direction of a travel path by a photography means in a light section method via a travel surface photography means (21). Corrected image information, in which a tilt in photographic image information has been corrected using inclination information, is generated on the basis of the photographic image information, the inclination information, and movement information via a road surface profile generation means (7), and thereafter the corrected image information is arranged using the movement information. Vertical motion information pertaining to the travel surface photography means is specified from image contents of overlapped regions. One portion of the corrected image information is cut out, and extracted image information is generated. While the height of the corrected image is corrected using the vertical motion information from the corrected image information, the extracted image information is arranged sequentially, and connected, and the road surface profile is generated.

摘要： A device for determining the temperature of a road building material applied by a construction machine in a placement width includes an infrared temperature measuring head, a motor and a controller. The infrared temperature measuring head is arranged to be twistable by the motor in a manner transverse to the direction of travel of the construction machine so as to scan the surface of the road building material to capture temperature measuring values of the surface of road building material during a rotational movement at a plurality of measuring points spaced apart from one another. The controller is configured to set a scanning speed as a function of a position of the measuring point.

摘要： A system and method for measuring the deformation over time of the surface of a non-Newtonian fluid in a sampling container in response to an airjet that is applied for a specified time. The change is the sample surface displacement is measured quantitatively by means of optical triangulation or other similar optical or electronic distance measuring device. After cessation of the airjet, gravitational forces cause the sample material to flow back to its original surface profile. Both the amplitude of the deformation displacement due to the force of the airjet and the recovered displacement, within specific time periods are characteristic of asphalt binder material with varying amounts of polymer or other additives used to control the ultimate properties and performance of the material. As a result, comparison of the quantitative measurements of control samples can allow discrimination from samples with different properties and hence different formulations.
