Latex cement mortar poured anti-rutting pavement structure and paving method thereof

An anti-rutting pavement structure, characterized in that it comprises, arranged consecutively from bottom to top, a semi-rigid base layer (1), a SBS emulsified asphalt adhesive layer (2), a Type II latex cement mortar poured asphalt concrete lower layer (3), a Type I latex cement mortar poured asphalt concrete middle layer (4) and a high viscosity modified asphalt SMA-13 concrete surface layer (5);

• the Type II latex cement mortar poured asphalt concrete lower layer (3) is composed of a macropore open-graded asphalt mixture and a latex cement mortar;
• wherein the mass ratio of the macropore open-graded asphalt mixture and the latex cement mortar is 5˜7:1;
• the porosity of the macropore open-graded asphalt mixture is 25˜35%, and it is formed by mixing an asphalt mixture with an aggregate smaller than 19 mm in a mass ratio of 4˜8:100;
• the latex cement mortar is formed by mixing a latex modifier, cement, standard sand and water in a mass ratio of 7:100:25:65;
• wherein the latex cement mortar is impregnated into the macropore open-graded asphalt mixture through the pores of the macropore-opened asphalt mixture;
• the Type I latex cement mortar poured asphalt concrete middle layer (4) is composed of a macropore open-graded asphalt mixture and a latex cement mortar;
• wherein the mass ratio of the macropore open-graded asphalt mixture and the latex cement mortar is 5˜7:1;
• the porosity of the macropore open-graded asphalt mixture is 25˜35%, and it is formed by mixing an asphalt mixture with an aggregate smaller than 16 mm in a mass ratio of 4˜8:100;
• the latex cement mortar is formed by mixing a latex modifier, cement, standard sand and water in a mass ratio of 6:100:20:60;
• wherein the latex cement mortar is impregnated into the macropore open-graded asphalt mixture through the pores of the macropore-opened asphalt mixture;
• the high viscosity modified asphalt SMA-13 concrete surface layer (5) is formed by mixing a high viscosity modified asphalt binder with an aggregate in a mass ratio of 5.5˜6.5:100;
• wherein the high viscosity modified asphalt binder is composed of a Styrene-butadiene-styrene copolymer modified asphalt, a thermoplastic rubber, a bonding resin and a plasticizer, in a mass ratio of 100:10:2:1.
