0Factors affecting friction or skid resistance
The maximum friction offered by pavement surface or the skid resistance depends upon the following factors :
(i) Type of pavement surface namely, cement concrete bituminous, WBM, earth surface etc.
(ii) Macro-texture of the pavement surface or its relative roughness.
(iii) Condition of pavement namely, wet or dry, smoothened or rough, oil spilled, mud or dry sand on pavement.
(iv) Type and condition of tyre i.s. new with good treads or smoothened and worn out tyre.
(v) Speed of vehicle
(vi) Extent of brake application or brake efficiency
(vii) Load and tyre pressure
(viii) the temperature of tyre and pavement, and
(ix) The type of skid, if any
