Determining Air Voids Content of Compacted Stone Matrix Asphalt Mixtures
Transportation Research Record: Journal of the Transportation Research Board, 2004This study compared the difference in air voids, optimum asphalt content, and voids in mineral aggregate (VMA) by using the saturated surface dry (SSD) and CoreLok methods for determining bulk specific gravity of the compacted specimen. The critical air voids level at which stone matrix asphalt (SMA) mixtures are considered to become permeable was ...

Modeling of Ultrasonic Testing about Void Content in Carbon Fibre
2007 8th International Conference on Electronic Measurement and Instruments, 2007Void is the most common flaws for composite material. Ultrasonic attenuation was serious because of the absorption of ultrasonic material and the material internal fragmentation caused by the discontinuousness. To solve the problem, ultrasonic pulse reflectance measurement system based on digital test was introduced.

Void content of a viscoelastic composite melt: Reduction during mixing
Polymer Composites, 1986AbstractMica and polystyrene in four ratios were sheared for three different times, each at three speeds, and at two temperatures in the viscoelastic region, in a screw mixer. From precise density measurements on the resulting composites, void volume fractions were calculated and found to be proportional to mica concentration and independent of total ...

Nondestructive Testing for Void Content in Glass-Filament-Wound Composites
Product R&D, 1969Abstract : Precise nondestructive methods for void determinations on glass-filament-wound composites in the form of rings and ring segments were tested for feasibility, with particular emphasis on the 0- to 3-volume-% void region. Experimental data related to void content are presented for several possibilities - infrared transmission, backscatter from

Measuring the Effective Air Void Content of Portland Cement Pervious Pavements
Cement, Concrete, and Aggregates, 2003Abstract The current literature indicates that air voids of Portland Cement Pervious Pavements (PCPP) should be 15–25%, to achieve desired permeability. However, there is no current AASHTO or ASTM test method to determine PCPP air voids.

Equality across the Legal Orders; Or Voiding EU Citizenship of Content
2014This chapter makes a simple claim. The direct by-product of a purely formalistic application of the national and supranational principles of ‘equality’ strictly within the confines of the different legal orders in, which is the case in the Union today, leads to injustice and is not sustainable. In this situation no one can legitimately claim that basic
