Pavement markings make travel safer for all road users. However, the material used for retroreflectivity can be slicker than the surrounding pavement. To maximize the safety of bicyclists, motorcyclists and pedestrians, MnDOT and local agencies explored the friction values of different marking materials. Project results produced valuable information on relative friction between pavement and marking materials and, importantly, identified effective testing tools to evaluate and compare products.

Testing High Friction Aggregates using SCRIM Technology at MnROAD
High Friction Surface Treatments (HFST) are pavement treatments that involve applying a high-quality aggregate and binder to pavement surfaces to help maintain friction. The treatment has significantly reduced crashes and injuries in wet and dry road conditions in high crash areas. However, HFST can be a costly treatment. Researchers, funded by MnDOT and the Local Road Research Board, are evaluating if taconite, a readily available Minnesota byproduct, can be an effective alternative treatment in low volume areas.

New Project: Pavement Marking/Colored Pavement Friction Differential and Product Durability
Pavement markings contain glass media to provide retroreflectivity. These markings are slipperier than surrounding pavement. The sudden difference in friction between pavement and pavement markings can create a safety hazard for pedestrians (including those with disabilities), bicyclists and motorcyclists, especially during wet conditions.
