This paper is concerned with the construction of concrete roads in britain today. After a brief introduction, the authors review the development of current design requirements, making reference to the doe specifications and technical memoranda and publications by TRRL. An account is given of the development of construction techniques with particular reference to the introduction of mechanical dowel placing techniques and the formation and sealing of grooves. The next part of the paper is concerned with the economics of concrete roads with special reference to the things that have happened since 1969 to improve the out look for concrete road construction, these include the TRRL analysis of the relative costs of flexible and concrete roads, specification changes and the acceptance of aggregates other than gravels. The authors discuss the surface of concrete roads in relation to the quality of ride and skid resistance, particular reference is made to the plastic grooving machine. After a brief discussion of roads in relation to the environment the authors conclude by discussing future developments including the use of the rapid analysis machine, the addition of carborundum to improve durability and skid resistance, the introduction of deep grooving and the possible development of better methods of case hardening the surface. This paper was prepared for presentation at the symposium on cement utilisation in road construction, ankara, turkey. /TRRL/
