Armerade och Modifierade Asfaltlager pa Cementbundet Grusbaerlager (CG): Provstraeckor pa Lambohovsleden Del 3, Linkoeping 1989. Byggnadsrapport (Reinforced and Modified Asphalt Wearing Course on Cement-Bound Gravel: Test Sections on Lambohovsleden Section 3, Linkoeping 1989. Construction Report)
Cement-bound gravel (CG) is used as a rigid roadbase and is included in a pavement type in the Swedish road construction directives (BYA-84). The material, which must be mixed in plant, consists of continuously-graded aggregate, cement and water. The cement content is approximately 110 kg/cu m. Test specimens produced in the laboratory must have a compressive strength of at least 10 MPa after 7 days. The CG roadbase should be laid with an asphalt paver and must be compacted with a vibrating roller to the necessary degree of compaction (97%). During 1985, tests were carried out on Lambohovsleden in Linkoping, which has been constructed with a CG roadbase, by varying the thickness of the AG layer. The aim is to investigate how the thickness of the AG layer influenced the occurrence of reflection cracks. After four years, no difference can be seen between sections with different thicknesses of the AG layer.
