采用自行研制的冲刷仪,以30 min、18 000次的冲刷量作为代表值,开展了骨架密实结构和悬浮密实结构两种不同结构类型的水泥稳定碎石在7 d、14 d、28 d龄期的冲刷试验. 结果表明,两种结构类型的水泥稳定碎石冲刷量随水泥用量增加总体呈下降趋势,且骨架密实结构的抗冲刷性能好于悬浮密实结构. 对于骨架密实结构,水泥用量由3.5%增加到4.0%时,冲刷量下降缓慢;水泥用量由4.0%增加到4.5%、5.0%时,冲刷量下降明显. 对于悬浮密实结构,水泥用量由3.5%增加到4.0%、4.5%、5.0%时,冲刷量下降较缓慢. 在养生期28 d下,两种结构类型的水泥稳定碎石冲刷量均随冲刷时间增长而增大,初期15 min内冲刷量增加较快,而后逐渐减弱,达到25 min后趋于平缓,规范中采用30 min的冲刷量评价水泥稳定碎石的抗冲刷性能是合理的. 为节省试验时间,也可用初期15 min内的平均冲刷速率评价水泥稳定碎石的抗冲刷性能.

To test the skeleton dense anti-erosion performance of the skeleton structure and suspended dense structure of two different structure types of cement stabilized gravel in 7d, 14d and 28d curing period, a erosion test apparatus was developed and the amount of 30mins, 18000 times was regarded as a representative value. The test’s results show that the erosion amount of the two structural types of cement stabilized macadam presents the overall downward trend when cement content increases, and skeleton dense structure has better anti-erosion performance than suspension dense structure. For skeleton dense structure, the erosion decreases slowly when the cement content increases from 3.5% to 4.0%; when the cement content increases from 4.0% to 4.5% and 5.0%, the erosion amount decreases significantly. For suspended dense structure, when the cement content increases from 3.5% to 4.0%, 4.5% and 5.0%, the erosion decreases more slowly. In the curing period of 28d, the erosion amount of the two structural types of cement stabilized gravel increases as the scouring time goes on. Beginning within 15mins, the erosion amount increases rapidly, and then gradually weakens, after reaching 25mins it tends to be gentle. In the standard, it’s reasonable to adopt the erosion of 30mins to appraise anti-erosion performance of cement stabilized macadam. To save test time, the average erosion rate within the initial 15mins can also be used to evaluate anti-erosion performance of cement stabilized macadam.
