CEMENT STABILISED MORAINE AS A ROAD CONSTRUCTION MATERIAL
COMENTSTABILISERAD MORAEN SOM VEGBYGGNADSMATERIAL
The object of this investigation was to see whether cement stabilised moraine can be used in road pavements. The first part comprised a study of the effect of cement content on the compressive strength of different moraine types. Organic soil, which usually occurs to a depth of 1.5 M, necessitates much higher cement contents. The second part comprised construction of two test pavements of cement stabilised moraine, as well as two control sections of unstabilised moraine. These were subjected to a vertical load varying from 0 to 44 kn at a frequency of 18-19 load alternations per second. This frequency is greater than that encountered in practical conditions, and this may have affected the results. The elastic deformations were measured. These became smaller the whole time, especially in the stabilised sections. Design rules have been drawn up for different types of stabilised moraine; the thicknesses of the bituminous wearing course and of the unstabilised subbase have been cut. Where fatigue cracks occur in the cement stabilised base, the pavements must be thicker, but are still less than in unstabilised constructions. /TRRL/
