Friction Aggregate

Special Provision for Friction Aggregate. October 1, 2010. This special provision was developed by the Bureau of Materials and Physical Research in January 2010 as a BMPR Special Provision and is now becoming a BDE Special Provision. It was created to address the possible shortage of traditional high-friction aggregate.

During the immersion process, the salt solution penetrates the permeable pore spaces of the aggregate. Oven drying dehydrates the sulfate salt precipitated in the pores. The internal expansive force of the re-hydration upon re-immersion simulates the expansion of water upon freezing. Polished Aggregate Friction Value D es ig n V eh ic le S

Frictional Resistance of Aggregates for Hot-Mix Asphalt

wear measurements were taken on stone-slag aggregate blends to determine the effectiveness of blends used in pavement mixtures. Differential wear results indicated that the high friction component of each blend could be improved by blending with softer carbonate aggregates, which also may be more cost effective. 17.

Open Graded Friction Courses Keeping an Open Mind

The aggregate structure of open graded friction courses makes them particularly susceptible from raveling. To avoid accelerated raveling, their use should be avoided in areas where snow and ice occur. In addition, particles on the roadway, particularly snow removal materials such as sand and salt, can clog up the pores in the pavement

Accelerated laboratory testing of aggregate friction

Dec 01, 2016 This paper presents a thorough analysis of an experimental method for measuring aggregate friction properties. The second-generation Aggregate Image Measurement System (AIMS) is used to measure coarse aggregate surface texture before and after polishing in a modified Micro-Deval (MD) test procedure, in addition to Variable Speed Friction Test (VST) samples.

Mar 19, 2017 Note. Above capacities are based on the assumption that material will be fed to conveyor uniformly and continuously. If loading is intermittent the conveyor should be designed for the maximum rate of loading likely to occur. For flat belts not troughed, use one-half of the above capacities.
