Abstract

The invention discloses a low-temperature cured epoxy asphalt mortar and a preparation method thereof. The epoxy asphalt mortar comprises the following components in percentage by weight: 10-20% of refined bitumen, 5-15% of epoxy resin, 5-10% of solubilizer, 40-70% of aggregate and 3-10% of curing agent. The low-temperature cured epoxy asphalt mortar has simple preparation process, low equipment requirement and low use cost, can be constructed and cured at normal temperature, not only is convenient to construct, but also has low requirement for equipment and is convenient to popularize and apply.

Description

technical field [0001] The invention relates to the related fields of asphalt pavement maintenance and repair, in particular to a low-temperature curing epoxy asphalt mortar capable of improving the surface layer performance of asphalt concrete pavement and sealing the pavement and a preparation method thereof. Background technique [0002] Under the new situation of rapid development of traffic, highway construction is advancing by leaps and bounds. Asphalt concrete pavement is more and more applied to high-grade highways, and the construction and maintenance quality of asphalt pavement is also paid more attention. Affected by various factors, the winter or low temperature construction of asphalt concrete pavement has become an unavoidable problem in the whole industry. [0003] The construction of asphalt concrete pavement has strict requirements on the construction climate. The "Technical Specifications for Construction of Highway Asphalt Pavement" JTGF40-2004 stipulates...
