VTTI’s Center for Sustainable & Resilient Infrastructure (CSRI) is saving lives through their efforts to improve our roadways. The center has made recommendations for procedures involving equipment specifications, testing protocols, and data quality assurance methods for network-level macrotexture measurement. Typically defined as surface features that are greater than 0.5 mm in height, macrotexture prevents water from spreading in between the pavement and tires, thus creating a drainage system.
Collaborating with industry and academic partners located in Virginia, Texas, and Minnesota, CSRI researchers outlined operational, equipment, and environmental components that impact macrotexture measurements, macrotexture characteristics, and new procedures that could help improve existing practices. This work resulted in three draft protocols for the American Association of State Highway and Transportation Officials.
