Introduction
Laurent Porot is a notable inventor based in Almere, Netherlands. He has made significant contributions to the field of asphalt technology, particularly in the rejuvenation of reclaimed asphalt. With a total of 2 patents, his work focuses on enhancing the properties of aged asphalt materials, making them more sustainable and efficient for road construction.
Latest Patents
Laurent Porot's latest patents include innovative asphalt compositions that incorporate reclaimed asphalt and rejuvenating agents. One of his patents details a composition that revitalizes the aged bitumen binder of reclaimed asphalt, restoring its physical properties to those of the original performance-grade bitumen. This rejuvenating agent, which contains a cyclic content of at least 5 wt. %, is derived from various acids, including aromatic and fatty acids. The improvements achieved through this innovation include enhanced softening, low-temperature cracking resistance, and better fatigue cracking resistance. Additionally, these rejuvenating agents allow for the use of higher levels of reclaimed asphalt, reducing costs and reliance on non-renewable materials.
Another patent focuses on asphalt compositions that utilize an ester-functional rejuvenating agent derived from tall oil. This innovation restores desirable properties of virgin asphalt to reclaimed materials, resulting in improved low-temperature cracking resistance and energy conservation during the mixing process. The rejuvenated asphalt compositions enable greater use of reclaimed asphalt, particularly Reclaimed Asphalt Pavement (RAP), further supporting sustainability in the road construction industry.
