TEST WITH CEMENT STABILIZATION, MIXED AT THE PLANT, ON HIGHWAY 79, VANNAS-75 (PROV MED VERKBLANDAD CEMENTSTABILISERING PA VAG E79, VANNAS-75)
On Highway E79, near Granolund, 5 test sections with roadbeds of 15-cm, cement-stabilized, sandy gravel, mixed at the plant, were laid in 1975 with one of the Vasterbotten Highway Administration's cement stabilization companies. The test sections were covered with 80 MAB 16T. The test sections were given different proportions of cement (5 and 10%) and different degrees of water saturation (less than 80% and more than 80%), and a reference section with a normal composition was also included. The purpose of the test sections - aside from the roadbed characteristics of cement-stabilized road surfaces - was to carry out a special study of how the degree of water saturation when the stabilized material was produced, on the one hand, and the proportion of cement, on the other, affected the frequency of the transverse cracks which are perceptible in the surface of the finished road. After 3 years had passed, tests indicated that the road's carrying capacity, expressed as a mean module on the average, was 2.2 times as high as before the stabilization. For sections with the higher proportion of cement, the carrying capacity was approximately 2.5 times as high. After 2 years, crack frequency in the surface was about normal.
