Cyclic triaxial tests on bituminous mixtures

Bituminous Sandstone Mixtures

In certain sections of the state of Indiana sources of recognized ag­ gregates for use in bituminous construction are very few, and the trans­ portation of aggregates to the job site from remote locations becomes necessary. Often the distance over which the aggregate must be moved is considerable, and the importation involves the expenditure of a size­ able sum of money, which it would be desir...

Assessment of Resistance to Rutting of High Modulus Bituminous Mixtures Using Full-scale Accelerated Loading Tests

In anticipation of the introduction of high modulus materials in the Swiss standards, a research project has been carried out for the evaluation of these bituminous mixtures. These mixtures make possible to reduce rut in base courses. With a temperature of 50°C, three test sections (two with high modulus and one with a reference material for base layer), were built in a building for ALT and wer...

Design Studies of Indiana Bituminous Concrete Surface Mixtures

For several years, the bituminous laboratory of the Joint High­ way Research Project has been concerned with the testing of bitu­ minous-aggregate mixtures and with the development of knowledge that would lead to an understanding of the properties of bituminous mixtures as satisfactory paving materials. At the Thirty-Eighth Annual Road School, a paper entitled, “Role of the Laboratory in the De...

DESIGNING FINE BITUMINOUS MIXTURES for HUH SKID RESISTANCE

Estimation of compaction of bituminous mixtures at microwave frequencies

This study is the beginning of a thesis dealing with the ability of electromagnetic methods based on waves propagation, to replace nuclear ones for measuring the compaction of bituminous mixtures. We study here the permittivity variation in function of compaction level of bituminous samples. For one part, a network analyzer with cylindrical cavities is used to obtain the permittivities of dry b...
