Pavement　skid　resistance,　which　depends　on　slip　speed,　is　an　important　factor　impacting　traffic　safety.　A　new　model　describing　slip　speed-friction　coefficient　relationship　with　3　parameters　are　validated　using　63　DFT　measurements　of　Asphalt　Concrete　(AC)　pavement　and　Portland　Cement　Concrete　(PCC)　pavement　respectively　with　various　highway　grades　and　surface　texture.　Regression　analysis　is　conducted　for　each　DFT　measurement　using　SAS.　Then,　statistical　characters　of　regression　R-square　are　analyzed　for　AC　and　PCC　pavement　respectively.　Most　values　of　AC　pavement　R-square　are　above　0.9　(only　one　is　0.8962).　About　90%　values　of　PCC　pavement　R-square　are　above　0.9　and　6　values　of　R-square　are　less　than　0.87.　Friction　coefficient　is　not　monotonic　decreasing　with　slip　speed　for　the　6　measurements　with　R-square　below　0.87.　It　is　concluded　that　the　model　has　good　reliability　for　AC　pavement　and　most　PCC　pavement.　Only　less　than　10%　PCC　pavement　measurements　cannot　be　properly　fitted　by　the　model.
