12 kinds of lime-flyash-gravel mixture with 3 gradations and 4 margins were designed.

Using a gravel-sand mixture from channel bottoms as a building material for check dams allows use of readily available material and may also facilitate use of flood water.

Construction technology of fly ash-lime grit basement in highway pavement;

Analysis of factors influenced the compaction effect of roadbed gravel pebble mixture;

The relations among Ca(OH)2 absorbed content,water requirement ratio,C mass content and their early-middle stage strength of lime-fly-ash mixtures are studied to put forward a new activity index to evalua.
