COLD BEHAVIOUR OF BITUMEN
| 项目名称： | COLD BEHAVIOUR OF BITUMEN |
| 摘要： | THE TREND TOWARDS THE USE OF HARDER BITUMENS IN ROADS MEANS THAT THERE IS A GREATER DANGER OF WINTER DAMAGE (CRACKING). IT IS THEREFORE NECESSARY TO MAKE A MORE ACCURATE STUDY OF THE BEHAVIOUR OF BITUMEN IN COLD WEATHER. INTERNAL DAMPING AND COEFFICIENTS OF EXPANSION AS A FUNCTION OF TEMPERATURE, AND HEAT ADAPTATION AND PHASE TRANSFER ARE BEING DETERMINED. RHEOLOGICAL MEASUREMENTS AND DETERMINATION OF FRAASS BREAKING POINT SERVE FOR THE EVALUATION OF THE METHODS. PRACTICAL EXPERIENCES WITH VARIOUS BINDERS IN ROADS ARE ALSO BEING CONSIDERED. |
