Bituminous pavement reinforcing material
The invention discloses a bituminous pavement reinforcing material. The bituminous pavement reinforcing material is prepared from the following raw material components in percentage by weight: 40-60% of cotton stalk cellulose, 20-45% of basalt fiber, 5-10% of polyester fiber, 3-5% of polyethylene and 1-2% of carbon black. The bituminous pavement reinforcing material has the advantages that strength of a pavement can be improved, the pavement can be prevented from cracking at a low temperature, and temperature shrinkage cracks are reduced; at a high temperature, partial bitumen expanded after being heated is absorbed, so that oil bleeding and high temperature loss of the bitumen, which are caused under a high temperature, are prevented; high temperature stability is improved, and the service life of the pavement is prolonged; pavement oil spot caused by formation of a micelle-shaped substance is prevented; leak and isolation of the bitumen are prevented; raw materials are available, a preparation process is simple, and cost for laying a bituminous pavement is greatly reduced.
