Novel road surface mixture of stably-gradated broken-stone cushion layer doped with fine limestone aggregates
The invention discloses a novel road surface mixture of a stably-gradated broken-stone cushion layer doped with fine limestone aggregates. The novel road surface mixture is characterized in that coarse broken-pebble aggregates formed by rolling pebbles and fine aggregates formed by rolling limestone are selected; the specifications are as follows: the fine limestone aggregates are divided into two types, namely, 0-2.36mm and 2.36-4.75mm; the coarse broken-pebble aggregates are divided into three types, namely, 4.75-9.5mm, 9.5-19mm and 19-31.5mm; and the construction mixing ratio is as follows: the ratio of 0-2.36mm limestone to 2.36-4.75mm limestone to 4.75-9.5mm broken pebbles to 9.5-19mm broken pebbles to 19-26.5mm broken pebbles is 27 to 8 to 15 to 22 to 28. The novel road surface mixture disclosed by the invention has the advantages that underground and surface water between a roadbed and a road surface can be effectively partitioned, the novel road surface mixture is used between a semi-rigid base layer and an asphalt layer, and reflection cracks of the semi-rigid base layer can be effectively reduced.
