Title: **Maria Luisa Chirinos: Innovator in Bituminous Emulsions**

Introduction

Maria Luisa Chirinos, a prominent inventor based in Caracas, Venezuela, has made significant contributions to the field of bituminous emulsions. With an impressive portfolio of 10 patents, her work focuses on enhancing the properties and applications of bitumen, particularly in road construction and protective coatings.

Latest Patents

Among her latest innovations, Maria Luisa developed a method for preparing High-Performance Road (HIPR) emulsions of bitumen in water. This process involves mixing 70 to 98% by volume of bitumen with a viscosity range of 200 to 500,000 mPa.s and 30 to 2% by volume of an emulsifying surfactant. The mixing occurs under low shear conditions, resulting in an emulsion with highly distorted bitumen droplets ranging from 2 to 50 microns, separated by thin films of water. Notably, these emulsions can be adjusted for lower bitumen content, making them ideal for road-making and the creation of protective surfaces.

Career Highlights

Maria Luisa has garnered valuable experience through her work with prestigious companies such as Intevep, S.A. and the British Petroleum Company, PLC. These roles have allowed her to develop her expertise in bitumen technology and its practical applications.

Collaborations

Throughout her career, Maria Luisa has collaborated with notable colleagues, including Ignacio A. Layrisse and Alistair Stewart Taylor. These partnerships have contributed to her innovative approaches and have expanded her influence within the industry.

Conclusion

Maria Luisa Chirinos stands out as a leading inventor in the realm of bituminous emulsions. Her dedication to innovation and her scientific rigor have paved the way for advancements that not only enhance the properties of road materials but also promote safer, more efficient construction practices. The impact of her patents is likely to resonate in the industry for years to come.
