Abstract
The invention relates to the technical field of concrete, particularly an asphalt concrete. The asphalt concrete is composed of the following components in parts by mass: 20-25 parts of waste asphalt, 5-8 parts of modified asphalt, 25-40 parts of cement, 10-15 parts of fine crushed ore, 7-15 parts of functional ore powder, 5-10 parts of fly ash, 5-8 parts of simulated steel fiber, 2-10 parts of halloysite and 2.8-6.4 parts of silicon carbide micropowder. Various materials can be mixed to enhance the deformation resistance and antiskid property of the pavement. The asphalt concrete containing the filler in the invention can reach and even exceed the properties of the traditional asphalt concrete using ore powder as the filler, and the cost is lower.
Description
Technical field
The present invention relates to technical field of concrete, especially a kind of bituminous concrete.
Background technology
Bituminous concrete is different by binder used, can be divided into asphalt and coal tar pitch two big classes；Also there is employing some country or mixes bitumen mixing.Different by kind of gathering materials used, rubble, gravel, chiltern, slag several classes can be divided into, use the most universal with rubble.Different by compound maximum particle size, the number classes such as coarse grain (less than 35～40 millimeters), middle grain (less than 20～25 millimeters), particulate (less than 10～15 millimeters), sand grains (less than 5～7 millimeters) can be divided into.Different by the compaction rate of compound, the number classes such as close-graded, half open gradation and open gradation can be divided into, open mix is also referred to as asphalt macadam.Wherein to mix the close-graded macadam-aggregate mix of heat paving durable in use for heat, and intensity is high, and good integrity is the representative materials building senior bituminous paving, applies the widest.Bituminous concrete is worked out by various countries different specifications, the heat that China formulates mixes hot black top compound technical specification, it is referred to as bituminous concrete with voidage 10% and following person, being subdivided into I type and II type, the porosity of I type is 3 (or 2)～6%, belongs to level of confidentiality distribution type, II type is 6～10%, belonging to half open gradation type, voidage more than 10% person is referred to as asphalt macadam, belongs to open gradation type；The mechanics index of physics of compound has degree of stability, flow valuve and porosity etc..
Often there is crack phenomenon in traditional asphalt concrete pavement, and automobile quantity is the most soaring simultaneously, and vehicle exhaust pollution on the environment becomes important social problem, need to administer energetically.
Summary of the invention
The technical problem to be solved in the present invention is: overcome deficiency of the prior art, it is provided that a kind of service life length, bituminous concrete that quality is high.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows:
