Molecular weights in the low range (<500 Da) are readily determined by vapor-density methods. For any one sample the boiling point elevation is determined at a series of concentrations of solute. Such determinations were carried out in practice by comparing the boiling point of pure solvent, ...

Asphalt concrete plays an important role in pavement material for highway engineering applications. In addition, many kinds of sustainable materials are attempted in replacement of aggregates for waste reduction. In specification of measurement of unit weight of AC specimens the wax sealing method (WSM...
athe current density j is finite over the entire width of the strip even when flux has only partly penetrated; 既使当涨潮部分只击穿了,电流密度j是有限的在小条的整个宽度;[translate] atwo contrasting field sites 二个contrasting领域站点[translate] ...
The density, stability, flow, percentages of the air Voids in the Compacted Mixture (VTM), compacted mineral aggregate (VMA) and the Voids Filled by Asphalt (VFA) were investigated for all the studied specimens. The main conclusions drawn from the current research implies that the optimum ...
Apparent molecular weight is defined as the sum of the products of the mole fractions of each component times the molecular weight of that component. The specific gravity of a gas is the ratio of the density of the gas to the density of air standard conditions of temperature and pressure. ...
A lightweight filling using recycled materials comprises: (a) parallelepipedal blocks (9) of plastic with a first density less than 100 kg/m<3> pref. 20-60 kg/m<3>; and (b) second set of parallelepipedal blocks (11) made from recycled waste, pref. compacted, of a second density ...
The desirability of an analyticalempir ical approach appears to be a universally agreed-on prec·ept among pavement engineers, particularly as a result of the Fifth International Conference on the Structural Design of Asphalt Pavements held in Delft, The Netherlands, in 1982. The analytical-empirical...
(2016) employed several count data models to estimate the frequency of rollover crashes in Malaysia for a four-year period (2007–2010). The results demonstrated that the speed limit, curvature, access point density and shoulder width were significant factors that gave rise to rollover crashes. ...
