| More details | ** The following points will be addressed during the presentation by the speaker. The IAT does not validate any claims made in this descriptor. There will be an opportunity for Q&A at the end of the presentation.** Butonal MB 5126 is a mechanically stable latex polymer dispersion designed to inject directly into an asphalt mixer. It ensures improvements in binder properties, such as a higher softening point and lower penetration. In the asphalt, the viscosity is temporarily reduced by foaming the bitumen caused by the small amount of water of the dispersion. This is advantageous when mixing the asphalt. As a result Butonal MB 5126 greatly enhances hot mix and also warm mix asphalt performance, including the production of performance-graded asphalts. Modification with these elastomers widens the asphalt’s useful temperature interval to improve resistance to rutting at high temperatures. The resulting binder also displays superb resilience to improve the pavement’s fatigue behavior, while diminishing any wear-induced cracking. Incorporating Butonal MB 5126 into asphalt production aligns with net-zero ambitions by offering a method to reduce carbon footprint within the traditional Polymer Modified Bitumen (PMB) value chain. The ability to modify asphalt directly at the mixing plant circumvents the energy-intensive processes typically associated with PMB, leading to substantial carbon savings and contributing to the sustainability goals of the industry. |
