粗、细集料分界尺寸及最大粒径一般将粗、细集料的分界尺寸定为4.75mm,即通过4.75mm筛孔的石料属于细集料,4.75mm以上的石料属于粗集料,粗集料的最大粒径参照目前规范中的级配范围取26.5mm.
半刚性基层的强度和刚性都随龄期的变化,随龄期的增长,强度和刚性都会增长,但不同材料增长的幅度不同,同一种材料在不同地区的增长幅度也不同,而且结合料的剂量越大,龄期的影响也越大.
干缩特性,体积收缩影响因素如下:细粒含量和矿物成分 土的塑性指数水泥剂量混合料的含水量暴露时间及失水量集料的平均粒径.国内外对无机结合料干缩性能的研究中,大都采用干缩应变和干缩系数两个指标表征.根据干缩应变和干缩系数的大小以及时间或失水量的关系对其路用性能进行评价.

Thick,the fine aggregate dividing line size and the maximum particle size will be generally thick,the fine aggregate dividing line size to decide as 4.75mm,namely belongs to the fine aggregate through the 4.75mm mesh's stone material,the 4.75mm above stone material belongs to the coarse aggregate,in the coarse aggregate maximum particle size reference present standard gradation scope takes 26.5mm.
The semi-rigid basic unit's intensity and the rigidity along with the stadium change,along with the stadium growth,the intensity and the rigidity can grow,but the different material grows the scope is different,the identical material is also different in the different area's growth rate,moreover the binding dosage is bigger,the stadium influence is also bigger.
The air shrinkage characteristic,the volume contraction influencing factor is as follows:Fine grain content and mineral component earth plasticity index cement dosage blend water content detection time and water loss aggregate average grain diameter.Domestic and foreign to inorganic binding air shrinkage performance research,uses the air shrinkage strain and the coefficient of shrinkage two target attributes mostly.Carries on the appraisal once in a while according to the air shrinkage strain and coefficient of shrinkage's size by prompt the water loss relations to its road with the performance.
