Abstract: To improve the content of waste rubber and explore the feasibility of waste rubber modified epoxy concrete (REC) as pavement materials, a series of REC with high volume content (0~50%) were prepared by equal volume replacement aggregates, and the pore rate, mechanical properties and pavement performance of REC were investigated. Results show that with increasing rubber content, the REC porosity first increases and then tends to be stable; the compressive strength and flexural strength decreases linearly, ultimate compressive strain and ultimate flexural strain are basically stable, and the ratio of flexural strength to compressive strength increases slowly when the content is below 40%, however, all significantly increase above 40%; the compressive stress-strain curve tends to be flat, and the flexible factor increases; the high temperature stability, low temperature stability and anti-sliding performance are enhanced; the freeze-thaw resistance are good, however, the water stability is significantly reduced. It is suggested that the rubber content should be 20% when REC as pavement materials with better mechanical properties and pavement performance:compressive strength of 33.5 MPa and flexural strength of 23.6 MPa; permanent deformation of 0.48 mm and dynamic stability of 70 000/mm in the rutting test; flexural strength of 17.0 MPa and the damage strain of 3100με in low temperature bending test; Marshall immersion residual stability of 75.67% in water stability test; British pendulum number (BPN) value of 48 in anti-slide test; no cracks or broken materials and no loss of quality after 300 freeze-thaw cycles. Considering the water stability of REC poor, it is recommended that REC should try to avoid the use in areas with serious water damage.
