WebHigh friction surface treatments (HFST) provide enhanced pavement friction in critical safety locations such as horizontal curves and bridge decks. HFSTs are a thin layer of durable, high friction aggregate bonded to an existing pavement surface using a liquid polymer resin binder. The resulting surface is extremely rough and polish-resistant ... WebOver the past 10 to 15 yr, the use of high-friction surface treatments (HFSTs) as a safety countermeasure has grown exponentially. HFSTs are pavement-surface treatments that restore or enhance pavement friction at locations with high friction demand, such as curves, ramps, and intersection approaches. While the crash-reduction

Can Local Aggregates Provide Enough Friction?
WebHigh friction surface treatments (HFST) are a safety enhancement that bonds high friction aggregate to road surfaces, dramatically and immediately reducing crashes, … WebHFST involves the application of very high-quality aggregate to the pavement using a polymer binder to restore and/or maintain pavement friction at existing or potentially high crash areas. The higher pavement friction helps motorists maintain better control in both dry and wet driving conditions. High friction surface treatments (HFST) are ... Webshould be the ideal choice for demanding high-friction applications. This thesis The aim of this thesis is to further improve the understanding of surface de-sign in relation to the acting friction mechanisms, primarily in boundary lubricated contacts. Both low-friction surfaces and high-friction surfaces are studied. how to screenshot youtube videos
