Concrete joints and joint sealing Explains why joints are required in an un-reinforced rigid concrete pavement and incorporates the results of questionnaires sent to a number of airfield operators. The guidance covers current practice and flags up issues of concern, providing information on the design, specification, construction, maintenance and performance of concrete joints.

Design and evaluation methods The four major methods of designing airfield pavements are compared and assistance is given in the task of deciding which one to use, based on three criteria that covers construction practice; failure condition, evaluation of strength of existing pavements and their limitations. The UK designs from the PSA and BAA are discussed and their background is explained.

Principles of design and assessment Provides a background to the basic principles of design and evaluation, including input throughout the whole life-cycle of a rigid airfield pavement. It covers structural behaviour, explains how a design thickness is obtained and includes information on modes of deterioration, pavement and sub-grade characteristics and aircraft loadings.

Surface finish, regularity and texture Covers the principles governing the requirements and current specification for surface finish, regularity and texture of concrete airfield pavements. Problems with surface finish are illustrated and remedial measures discussed. The importance of texture is covered along with a range of methods of achieving it, both in fresh and hardened concrete.

Rigid airfield pavements This guidance note provides advice to designers and constructors on the use of keys to provide load transfer at longitudinal joints in concrete airfield pavements. The guidance note describes the requirement for load transfer at joints, the potential advantages of using a keyed joint, historical practice and performance, design methods and construction practice.
