Expansion Joint Detail in Mass Concrete

[RyUIUC]

I am detailing a large mass concrete earth retaining wall that is several hundred feet long. A reviewer advised to implement expansion joints approximately every 100 feet to allow for thermal growth/contraction of the concrete walls. Most expansion joint details I have seen appear to be applicable to slabs on grade or walls of some nominal thickness and perhaps not appropriate for a wall that may be 20 feet wide at its base. I cant imagine using that much expansion joint filler material at each cross-section. Does anyone have a good reference? I have seen very old drawings where they either specify creosoted cypress boards to be anchored between concrete sections and left in place as well as sections where only the outter 8 inches of the concrete section is adjoined with the expansion joint material between them then a construction joint boyond. Any help is appreciated.

See section 2.1 or 2.1.3.6 on document HS of the Código Técnico (Spanish)

This more or less automatizes what to put in building waterproofing.
