An account is given of the design and installation of the British Rail paved concrete track system (pact) in Spain for Spanish National Railways (renfe). The design for the slab track was based on a standard British rail slab of 2.400 M width modified to suit the renfe rail gauge. The slab was continuously reinforced with 20 16 mm-dia high-tensile longitudinal bars and 16 mm-dia transverse bars. Prior to constructing the paved slab some earthworks stabilisation was carried out. The reinforcing steel was fabricated into A mat as paving proceeded. Special techniques had to be employed during the concreting period so that work could proceed in high temperatures (39 C). /TRRL/
