VEHICLE-PAVEMENT INTERACTION STUDY

This final report describes methods, procedures, and results of a study commenced in September 1959. Investigations were made in the laboratory on selected pavement surfaces, measurements were made on pavement surfaces on Texas highways and on control surfaces constructed at the Texas A&M Research Annex. The effect of rainfall was examined and an equation was developed to relate water depth to other variables. Finally, an expression was developed relating pavement characteristics, water depth, vehicle speed, and tire tread depth to skid or friction number. /FHWA/
