Tests performed with a standard passenger car at speeds up to 80 miles/hour did not provide any indication of control problems when weaving over dry thermoplastic or painted stripes. Also stopping tests at 30 miles/hour with two side wheels on the double 4 in and 8 in solid stripe did not cause any loss of vehicle control. No loss of control was noted in special crossing over tests on the 8 in solid stripe at speeds up to 60 miles/hour. When these tests were repeated under wet pavement conditions, there was no noticeable loss in vehicle control, except during braking from 30 miles/hour with two wheels on the stripe. On both thermoplastic and painted stripes, the vehicle swerved away from the stripe. All of these tests were performed by experienced drivers. Skid resistance tests on the thermoplastic stripe are very low, and in the range of a 'bleeding' asphalt pavement. The painted stripe was somewhat higher, but quite variable in different test areas. It appears that the friction value for painted stripes is influenced by the original pavement texture, and the film thickness of the traffic paint. (Author)
