自1982年北京引进了粉煤灰石灰砂砾混合料作为修筑道路材料后,已经代替了级配砂石,使松散材料变为半刚性板体材料,提高了道路质量,延长了使用年限。但是当时低温施工问题还未能解决,粉煤灰石灰砂砾混合料的使用受到限制。因此,我们在85年开始着手这方面的研究探索,准备了相应的器具,制定了实验条件,计划于86年三月正式开始做粉煤灰石灰砂砾混合料的冰结试验。
Since the introduction of fly ash, lime and gravel mixture in Beijing as a building material for road construction in 1982, it has replaced graded gravel, making loose material into semi-rigid plate material, improving road quality and extending useful life. However, the problem of low-temperature construction was not solved at that time, and the use of flyash limestone gravel mixture was limited. Therefore, we started 85 years of research and exploration in this regard, prepared the appropriate equipment, set the experimental conditions, is scheduled to begin in March 86 to begin the freeze test of fly ash lime grit mixture.
