A sustainable pavement is constructed by creating a construction structure for a hot mix asphalt (HMA) pavement according to a pavement project; calculating a greenhouse gas (GHG) emission of the HMA pavement; performing a sustainable construction on the HMA pavement to modify one or more layers in the HMA pavement to form a sustainably constructed pavement; calculating a GHG emission of the sustainably constructed pavement; and obtaining a carbon reduction by comparing the GHG emissions of the HMA pavement and the sustainably constructed pavement.

An improved parking lot pavement analysis system is described that analyzes field survey data and generates a report which provides the necessary information to make the most cost-effective maintenance and repair decisions for commercial and residential parking lots. The pavement analysis system can be implemented on an existing PC computer to provide a user-friendly way of standardizing and guiding the visual survey and pavement sampling to determine existing conditions. The pavement analysis system guides entry of data indicating the pavement's existing condition, and then calculates and recommends maintenance and repair options. The calculations are based on an expert diagnostic system analysis which substantially reduces the requirement for expert interpretation. A complete life cycle cost analysis is performed, and this allows the user to make an informed decision about what type repairs are most appropriate for a particular situation. A comprehensive standardized, easy to read, report can be printed to convey sufficient information to enable a parking lot manager to time repairs with pinpoint accuracy.

A method and apparatus for enhancing prints, such as fingerprints, for direct comparison. The method utilizes a transparent pressure-sensitive gel to capture a print pattern. A polarized beam of collimated light is passed through the gel. The pattern features impressed in the surface of the gel scatter light out of the optical path. The beam is then directed to a polarizing element oriented so as to filter out the scattered light rays and thereby produce a high-contrast image for direct viewing or further automated processing. In one embodiment of the apparatus single pressure-sensitive transparencies of individual prints are inserted in a polarized light path. In another, a film transport mechanism exposes successive regions of a strip of transparent pressure-sensitive film in a window for application of individual prints and advances the film to position each image imprinted on the film surface in the polarized light path. In both embodiments the modified light beam emitted by the transparency is projected through a polarization analyzer. A lens train further enhances the image by magnifying it and apodizing the enlargement.
