Pavement paving filling type large-particle-size cement stabilized macadam base material and method

Abstract

The invention relates to the technical field of road materials, in particular to a filling type large-particle-size cement stabilized macadam base material for pavement paving and a method. The filling type large-particle-size cement stabilized macadam base material is prepared from the following materials in parts by weight: 10-20 parts of cement; 10-20 parts of medium sand; 10-20 parts of fine sand; 60-80 parts of stones; 40-50 parts of slag; 20-30 parts of coal cinder; 20-30 parts of lime powder; and 10-20 parts of a glass fiber mesh. A preparation method of the filling type large-particle-size cement stabilized macadam base material for pavement paving comprises the following steps that S1, an old pavement is treated, foreign matter on the old pavement is cleared away, a road roller is adopted for rolling and flattening, and then watering and airing are conducted; s2, lime powder is spread, specifically, lime powder is spread on the old pavement treated in the S1, a road roller is adopted for rolling and flattening, and then water spraying treatment and air drying are conducted. The multiple layers of glass fiber nets are embedded in the concrete base layer during construction, so that the deformation resistance of the base layer is high, the bending and tensile strength is high, the cracking phenomenon of the pavement base layer can be effectively prevented, and the service life of a road is prolonged.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to a road paving filling type large particle size cement stabilized crushed stone base material and method. Background technique [0002] Highways refer to roads connecting cities, between urban and rural areas, between villages and villages, and between industrial and mining bases, which are built in accordance with national technical standards and approved by the competent highway department, including expressways, first-class roads, and second-class roads , third-class roads, and fourth-class roads, but does not include trails naturally formed in fields or rural areas. It is mainly used for automobiles and has certain technical standards and facilities. During the construction of the road, it is necessary to use base materials for paving, so that the durability of the road is better. [0003] Chinese Patent No. 201110433843.7 discloses a phosphogypsum highway base materia...
