This data in brief article summarizes structural data obtained from monocomponent melt-spun and offline drawn poly(ethylene terephthalate) (PET) monofilaments, as well as from melt-spun bicomponent core-sheath PET-polyamide 6 (PA6) filaments. The diameters of the single filaments range from 27 mu m to 79 mu m. Presented analysis techniques and results thereof are (i) Raman mapping of filament crosssections: 2D maps of peak positions, widths, peak area ratios; (ii) attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR): ATR-FTIR spectra and extraction of surface crystallinity; (iii) wide-angle x-ray diffraction (WAXD): WAXD patterns and extraction of average crystallinity; (iv) small-angle x-ray scattering (SAXS): SAXS patterns and determined crystallite sizes and long-spacings; (v) differential scanning calorimetry (DSC): thermograms and extracted average crystallinity as well as thermal properties; (vi) atomic force microscopy (AFM): AFM image of the surface of an embedded fiber cross-section.

A large number of sensors installed as part of the European cooperative project, Eureka Logcham Footprint, are used to examine the effects of individual vehicles on the road pavement and the environment. The weigh-in-motion data recorded at the Footprint Monitoring Site near Lenzburg, Switzerland are analyzed and figures are presented which describe the nature of the traffic experienced at the monitoring site. The weighin-motion data are matched to data from a prototype stress- i n-moti on sensor from the same site and the two datasets are compared. The ability of the stress-in-motion sensor to record the contact stress distribution is discussed and procedures are proposed for describing the shape of the distribution using a relatively small number of parameters. A method for quantifying distribution shape in terms of an "m"-ness value is proposed. A finite element model of the road is constructed, validated, and used to predict the stresses and strains in the pavement related to particular contact stress distributions. It is demonstrated that, for all but the heaviest tires, the shape of the stress distribution has a significant effect on the stresses and strains within the pavement., QC 20120229

With modern heavy vehicles using higher inflation pressures and higher axle loads the dynamic measurement of the tire-pavement contact force/stress is essential not only for tire development but also in road research for the investigation of factors which may lead to excessive damage of pavements. In this paper the results of laboratory tests with a prototype stress in motion (SIM) quartz sensor trafficked with a one-third scale load simulator (MMLS3) are presented. The tests were designed to vary parameters such as tire inflation pressure, speed, ambient temperature, lateral position, and angle to direction of travel in a controlled environment in order to isolate the influence of these parameters on the SIM sensor results. All other controllable variables remained constant while the target parameter was varied. Tire inflation pressures were calculated from these data. The laboratory tests show that the prototype sensor promises to be an effective investigative tool for SIM measurements., TSC import 1734 2012-02-14. QC 20120305

Stress-in-Motion data from the A1 motorway in Switzerland is examined. The data is classifiedby the load and stress distribution of the wheel and five examples are selected as beingrepresentative of the highly loaded wheels passing the site. A finite element model is used toexamine the effects that these five distributions have on the A1 pavement. It is concluded thatwhile there is an approximately linear relationship between pavement strain and wheel loadwhen other parameters are held constant, the effects of the stress distribution are moresignificant in the cases presented. It is also shown that the different stress distributions producesignificantly different effects on pavements irrespective of the wheel load., QC 20120509
