A system for determining a property of a paving-related material is provided. Such a system comprises a measuring device for selectively and directly measuring the property. A computer device is capable of executing a software program product and communicating with the measuring device. The computer device directs the measuring device to measure the property of the paving-related material according to a parameter determined by the software program product, and to receive data comprising the measured property from the measuring device. A communication element operably engaged between the measuring device and the computer device allows communication therebetween. The communication element is configured to allow the computer device to be spaced apart from the measuring device, thereby allowing the computer device to be prepared, to include the parameter and to manipulate the data, in spaced apart relation with respect to the measuring device. An associated method is also provided.

A method is provided for nondestructively determining a material property of a porous sample. A first vessel is evacuated to a sub-atmospheric pressure, while a test pressure, greater than the sub-atmospheric pressure, is established in a second vessel containing the sample. The pressures of the first and second vessels are equalized by opening a valve mechanism therebetween. The resulting pressure change in the second vessel exhibits an initial pressure drop followed by a transition to an equalization pressure. The envelope volume of the sample is determined from a minimum pressure attained by the second vessel upon initial opening of the valve mechanism, wherein the minimum pressure is related to the initial pressure drop. The envelope density of the sample is thus a quotient of the mass and the envelope volume of the sample. The absolute density and relative absorption of the sample may also be determined and an associated system is provided.

System and method for determining material properties of samples

A system adapted to determine a property of a paving-related material is provided. Such a system comprises a central computing system housing database, such as a geographic information system (GIS). A measuring device for selectively and directly measuring the property of the paving-related material is remotely disposed with respect to the central computing system and operably engaged with a locating device, such as a global positioning system (GPS) device, for determining a location of the measuring device when the property of the paving-related material is selectively measured thereby. A portable handheld computer device is in communication with the measuring device, the locating device, and the central computing system, wherein the handheld computer device is configured to receive data, comprising the measured property of the paving-related material and the corresponding location of the measuring device when the property is selectively measured thereby, from the measuring device and the locating device, and to communicate the data with the central computing system for incorporation of the data into the database. An associated device, apparatus, and method are also provided.
