A method for the accurate calculation of some thermodynamic properties of non-polar or moderately polar substances, based on Van Laar's theory
Autor: W. Heukelom
Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 68:661-695
Van Laar's method to calculate the critical conditions is based on the molecular constants a and b in van der Waals' equation of state. In certain cases inaccuracies in the calculated values of a may lead to results which deviate considerably from th

An improved mobile unit for the dynamic testing of pavements
Autor: A J G Klomp, W Heukelom, Th W Niesman
Publikováno v: Journal of Physics E: Scientific Instruments. 1:127-132
A description is given of a newly built equipment for the dynamic investigation of roads and runways. Attention is paid mainly to the construction of a mechanical vibrator with adjustable eccentric masses designed to generate vertical sinusoidal forc

Dynamic Testing of Pavements
Autor: W. Heukelom, C. R. Foster
Publikováno v: Transactions of the American Society of Civil Engineers. 127:425-451
Each time vehicle passes over pavement, surface is deflected and rebounds, creating strain conditions for 0.01 to 0.1 sec; methods used in Netherlands for simulating and studying such dynamic conditions in pavements, base courses, and subgrades; use

Dynamics Testing of Pavements
Autor: W. Heukelom, C. R. Foster
Publikováno v: Journal of the Soil Mechanics and Foundations Division. 86:1-28
Each time a vehicle passes over a pavement the surface is deflected and rebounds, creating temporary strain conditions for 0.01 to 0.1 sec. Information about these strain conditions can be obtained by observing the movements of the pavement under sim

Analysis of Dynamic Deflexions of Soils and Pavements
Autor: W. Heukelom
Publikováno v: Géotechnique. 11:224-243
Synopsis The deflexions of soils and roads under sustained vibration conditions have been observed. The resistance to deformation is expressed in the dynamic stiffness. The dynamic stiffness is found to consist of an elastic part, which is considered
