LEAN CONCRETE ROADBASES. PARTS 1 AND 2

Lean concrete mixes involve the use of washed aggregate of concreting quality, a low cement content and a low water content; the material is laid without joints other than construction joints, compacted by vibrating rollers, cured and, in flexible pavements, surfaced with bituminous material. This two part article presents a review of experience in the United Kingdom with lean concrete over a period of 25 years, and an outline of current practice in relation to pavement design, mix proportions and construction procedures. Lean concrete is described as being principally a road base rather than a sub-base material, and its use in the construction of roads covering the full spectrum from housing estates to motorways is discussed. /TRRL/
