Holly Asphalt's purchase of five Dynamic Shear Rheometers over a period of eight years is testament to Malvern's ability to provide exemplary support to asphalt producers, and to sustain and nourish long-term commercial relationships.  Holly Asphalt operates five terminals in the southwestern US and is part of the Holly Corporation (www.hollycorp.com), an independent petroleum refiner and marketer.  Like all asphalt producers, Holly uses rheometry for final QC. Rheological properties have a critical impact on asphalt pavement performance and testing to well-defined industry standards is essential before shipping.

"For me what really differentiates Malvern is exceptional customer support," comments Bob McGennis, Technical Manager, Holly Corporation. "The company has a non-bureaucratic, ‘can-do' attitude and will go that extra mile to provide us with everything we need. Bohlin was the first company to develop a rheometer specifically designed to meet the needs of asphalt producers. Malvern has capitalised and built on this legacy. They really understand the asphalt industry and our reliance on sound and accurate rheological data." 

Asphalt testing is a demanding rheological application, primarily because of the temperature sensitivity of measurements. The Superpave^TM specifications set out criteria for QA/QC acceptance for different grades, and test methods are very closely defined. Malvern offers a suite of rheometers specified to meet the demands of the industry, with integral, user-friendly software that automates and streamlines asphalt measurement. These solutions are supported by information rich, industry-specific web content, an ambitious and informative on-line education programme and a global network of application specialists.http://www.malvern.com/asphalt
