Air steel film coefficient
WebDescription. Under most circumstances, airfield concrete pavements are designed as jointed plain concrete pavements (JPCP), containing steel only at pavement penetration areas … WebThe coefficient depends on the air conductivity (kair), thermal properties of the interface materials and the magnitude of the gap (g ). The formula from Lewis, (2000), Lewis & Ransing, (1998), is adopted: h = kair / ( g + kair / ho ).
