This paper reports the development of a miniature pressure sensor on the optical fiber tip for in vitro measurements of rodent intradiscal pressure. The sensor element is biocompatible and can be fabricated by simple, batch-fabrication methods in a non-cleanroom environment with good device-to-device uniformity. The fabricated sensor element has an outer diameter of only 366 μm, which is small enough to be inserted into the rodent discs without disrupting the structure or altering the intradiscal pressures. In the calibration, the sensor element exhibits a linear response to the applied pressure over the range of 0 - 70 kPa, with a sensitivity of 0.0206 μm/kPa and a resolution of 0.17 kPa.

Novel Design

A novel design for a Fabry-Perot Interferometric Sensor (FPIS) consisting of a Fabry-Perot cavity formed between two bonded surfaces is discussed. The Fabry-Perot cavity and the optical fiber to which it is coupled are used as the sensing element and interconnect, respectively. The Fabry-Perot cavity is fabricated using the Micro Electro Mechanical Systems (MEMS) technology. The introduction of a center rigid body diaphragm gives this sensor considerable advantage when compared with previous Fabry-Perot cavity based sensors.

This research was undertaken to study the combined effect of repeated vehicle loads and low temperatures on the design thickness for both recycled and virgin asphalt pavements. It included three parts of work: theoretical analysis, laboratory tests, and computation. In the theoretical analysis, the finite layer method was used instead of the conventional layered theory to obtain the relationship between vehicle loads and the mechanical parameters in the pavement layers. In the laboratory tests, the behaviour of a recycled asphalt concrete mix consisting of 42% reclaimed and 58% new material was compared with that of a virgin asphalt concrete mix of similar characteristics. Finally, a computer program FPAVE was developed to determine the pavement thicknesses directly and conveniently. These thicknesses were then plotted in the form of curves for comparing the two types of pavements as well as for comparison with the thickness at 22 °C. Key words: asphalt pavement, fatigue, pavement design, recycling, temperature.
