Use of Rough Pavement Texture
The potential for hydroplaning may be minimized to some extent if the pavement has a rough texture. A very rough pavement texture benefits inlet interception. However, in a contradictory sense, very rough pavement texture is unfavorable because it causes a wider spread of water in the gutter. Rough pavement texture also inhibits runoff from the pavement.
Cross cutting (grooving) of the pavement is useful for removing small amounts of water such as in a light drizzle. The Department discourages longitudinal grooving because it usually causes problems in vehicle handling and tends to impede runoff from moving toward the curb and gutter.
