摘要：	One of the major factors of vehicle crash is lack of sufficient friction at the tyre-pavement interface. Road user's safety has become a major critical issue on highways as well as on urban roads in the present scenario due to travel of high speed and construction of high speeds corridors. Safety is one of the parameters which has always bothered the highway engineers. Heavy investments are being made in the country towards upgradation, improvements and rehabilitation of the existing road network to provide safe, faster, easier and economic transportation system. It is the responsibility of a highway engineer to construct, maintain and ensure the pavement in good condition so as to minimize road related accidents. Skid resistance is one of the many factors which considerably affect the road user's safety. It depends on pavement surface, vehicle characteristics & speeds, road users behavior and weather conditions. This paper deals mainly with the outcome of a study undertaken by the Central Road Research Institute (CSIR-CRRI) to study the effect of macro texture and micro texture on skid resistance. Different pavement surfacing types, old and new for both Bituminous and Cement Concrete were studied. Micro texture and macro texture were measured using British Portable Skid Resistance Tester (BPT) and Sand Patch Method respectively. The data so obtained for the various pavement surfaces has been analyzed and a good correlation is found to exist between British Pendulum Number (BPN) and Mean Texture Depth (MTD) for both the new and old Bituminous Concrete (BC) surfaces. The study further indicates that skid resistance values show an increasing trend with increase in texture depth for most of the test locations conforming to the findings reported by earlier studies.
