20130068135 | PROCESS FOR MANUFACTURING COLD BITUMINOUS MIXES, COLD BITUMINOUS MIXES WITH CONTROLLED WORKABILITY AND USE THEREOF FOR PRODUCING ROAD PAVEMENTS - The present invention relates to a process for producing cold bituminous mixes, comprising the following successive steps: a. in a mixer, coating, at ambient temperature, all of the solid mineral fractions with all of the binder in emulsion, and optionally a portion of fluxing agent, over a time interval T sufficient to observe a coating of the mix; then b. at the end of the time interval T, adding the remaining amount of fluxing agent, over a time interval t, such that the T/t ratio is greater than 2, the other mixing conditions of steps a) and b) being otherwise substantially identical. The present invention also relates to cold bituminous mixes, capable of being obtained by the process according to the invention and the use thereof for the production of wearing courses, the production of emulsion-stabilized gravels or the production of storage-grade mixes. | 03-21-2013 |
20120302672 | SYNTHETIC BINDER ESSENTIALLY MADE OF MATERIALS FROM RENEWABLE RESOURCES, IN PARTICULAR OF VEGETABLE ORIGIN, AND APPLICATIONS THEREOF IN ROAD ENGINEERING - The invention relates to a synthetic binder characterized in that said binder includes: from 20 wt % to 100 wt % of at least one polyester based essentially on material from renewable resources, in particular of vegetable origin, having: a hydroxyl number below 100 mg KOH/g, an acid number below 25 mg KOH/g, an iodine number below 100 g I | 11-29-2012 |
