Abstract

The paper describes trials and tests at Luton airport to assess the suitability of concrete blocks as a surface for aircraft pavements which are subjected to slow moving and static aircraft loadings. The results of the trials indicated that concrete blocks have certain advantages over the pavement-quality concrete and Marshall asphalt surfaces traditionally used for aircraft pavements. In particular, they were found to be capable of rapid installation even in adverse weather conditions. Following the satisfactory performance of the trial areas, nine apron stands and two runway end turning areas were resurfaced using rectangular concrete blocks (a total area of 12700 sq m). The paper also gives the results of plate bearing tests carried out while the western runway end turning area was being resurfaced. These tests showed a 14% increase in pavement bearing strength after resurfacing with concrete blocks. (Auhor/TRRL)
