振碾混凝土是使用振动压路机通过外部振动和碾压的一种干硬性混凝土,它与普通混凝土的主要区别是,由于拌合物配合比的不同,使振碾混凝土比普通混凝土的用水量和水泥各节约1/3。这种拌和物在充分振碾下将获得最大密实度,它所需要的振动碾压能力是很重要的。安徽省公路局于1982年铺了一段试验路,1983、1984年与交通部公路科学研究所合作又铺了一段试验路,证明可以使用325~＃水泥铺筑300~＃的混凝土路面,结果令人满意。其施工工序与铺筑沥青混凝土
Vibro-impact concrete is a kind of hard and rigid concrete which is vibrated and crushed by vibration roller. The main difference between Vibro concrete and ordinary concrete is that the proportion of vibration-crushed concrete is lower than that of ordinary concrete and that of cement Each save 1/3. This mixture will get maximum densification when fully vibrated, and the vibration crushing capability it requires is important. Highway Bureau of Anhui Province in 1982 paved a pilot road, 1983, 1984 and the Ministry of Communications Highway Science Institute paved a trial of another road, that can use 325 ~ # # concrete paving 300 ~ # concrete pavement, so that People are satisfied. The construction process and paving asphalt concrete
