Book Description
Lean concrete base, as we use the term in California, is cement treated base aggregate that is mixed with 8 to 8.5 percent portland cement, 13 to 17 percent water and approximately 3 percent entrained air in concrete mixing equipment and then placed with slip form paving equipment. This construction is being developed as a substitute for cement treated base, in the construction of portland cement concrete pavement, primarily to provide a more erosion resistant base and thus inhibit the development of joint faulting. Two relatively large scale field trials were undertaken wherein a substantial portion of two different highway construction projects were built with lean concrete base instead of cement treated base as the base for portland cement concrete pavement.

Book Description
This report covers details of two large-scale field trials of lean concrete base (LCB). By adding additional cement and water to aggregates used for cement treated base (CTB), a plastic mix is produced which can be placed with a slipform paver using only internal vibration for compaction. Between 50 and 100 percent additional cement was required to produce LCB with compressive strength comparable to the in-place strength of CTB. LCB was found to have greater stiffness and a more sealed and abrasion resistant surface than CTB. Some of the increased costs due to additional cement are offset by greater production and the use of less placing and finishing equipment.
