THE RELATIVE EFFECTS OF SEVERAL FACTORS AFFECTING RAINWATER DEPTHS ON PAVEMENT SURFACES

THE AMOUNT OF WATER THAT CAN BE EXPECTED TO EXIST ON VARIOUS PAVEMENT-SURFACE TYPES IS DETERMINED UNDER NORMAL RANGES OF PAVEMENT CROSS SLOPES, RAINFALL INTENSITIES, SURFACE TEXTURES, AND DRAINAGE LENGTHS. EQUATIONS ARE DEVELOPED THAT RELATE THESE VARIABLES AND THEIR RELATIVE EFFECTS TO WATER DEPTH, AND BACKGROUND INFORMATION AND PERTINENT PAST RESEARCH PERTAINING TO HYDRAULICS OF WATER FLOW OVER PAVED SURFACES ARE GIVEN. WHEREAS INCREASES IN PAVEMENT CROSS SLOPE AND SURFACE TEXTURE RESULTED IN DECREASED WATER DEPTHS, INCREASES IN RAINFALL INTENSITY AND DRAINAGE LENGTH INCREASED WATER DEPTHS. THESE FINDINGS WILL BE USEFUL TO HIGHWAY ENGINEERS IN DETERMINING PROPER GEOMETRIC DESIGNS AND PAVING MATERIALS COMMENSURATE WITH ACCEPTABLE PAVEMENT FRICTION CHARACTERISTICS AND SERVICE DEMANDS. SUGGESTIONS FOR FURTHER RESEARCH ARE ALSO INCLUDED. /AUTHOR/
