Description
technical field [0001] The invention belongs to the technical field of modified asphalt concrete, and relates to an isophthalic unsaturated polyester resin modified asphalt concrete and a preparation method thereof. Background technique [0002] With the development of economy and road transportation, the span of bridge structure is getting larger and larger. The bridge deck pavement layer is the surface layer where the bridge deck is in direct contact with the traffic. It can protect the bridge deck from the direct effects of vehicle load, temperature load and water. The quality and durability of the pavement directly affect the running of the vehicle. quality and service life of the pavement. Therefore, the bridge deck pavement should have the characteristics of good anti-rutting performance, anti-slip surface, and good water and temperature stability. [0003] At present, the types of bridge deck pavement widely used at home and abroad are mainly cast asphalt concrete, ...
