Abstract
The invention relates to a non-maintenance pitch road and relative construction, wherein said construction comprises: it constructs three layers or two layers, while the bottom is pore concrete, while said layer can be avoided; the upper layer is the high-density solid pitch concrete, which uses mine powder to replace some pitch via bag theory and particle package theory; the mass percentages (kg/m3) after replacement are broken stone at 1276-2146, chip at 518-680, fine sand at 120-280, pitch at 80-155 and fined mine powder at 0-60; the diameter ration of particles are broken stone: chip >=3.15; chip: fine sand >=3.15; find sand: grinded mine powder >=3.15; and the theory density is 1580-2880/3; and the production comprises: mixing and heating said raw materials, rolling and shaping. Since the invention uses bag theory, optimizes the mass ratio and particle diameter ratio, to improve the strength of pitch concrete and reduce the pollution.
Description
Technical field: the present invention relates to maintenance free asphalt pavement surface and the job practices used in a kind of various engineering construction.
Background technology: along with China's rapid economy development, the quickening of capital works rhythm, pavement asphalt concrete is widely used, and is in crucial position in our life equally, no matter be trip or lodging, we are using it every day.But, bituminous concrete processing and production, except that special requirement, the technology of employing and proportioning all are common ways, the defective of existence is that intensity is not high, bad easily, has influenced the road surface use, wastes a large amount of manpower and materials.
Summary of the invention: the present invention has overcome above defective, and a kind of energy conservation is provided, maintenance free asphalt pavement surface that overlength is durable and job practices.Described job practices is divided three layers or two-layer the construction, and bottom is a poor concrete, and the middle level is the graded broken stone layer, and the upper strata is the high compact bituminous concrete; Its upper strata high compact bituminous concrete is the theoretical and theoretical breeze replacing section pitch of using of particle parcel according to pocket, and the mixing ratio by weight after the displacement is (kg/m3) rubble 1276-2146, aggregate chips 518-680, fine sand 120-280, pitch 80-155, ground blast furnace slag 0-60; Particle diameter is than being rubble: aggregate chips 〉=3.15, and aggregate chips: fine sand 〉=3.15, fine sand: ground blast furnace slag 〉=3.15, solid density are 1580-2880/m3; Its production method is the above-mentioned material heating to be mixed stir roller-compaction.Because the present invention has adopted " pocket " theory, the construction of three floor height performances, and concrete strength is significantly improved, save a large amount of raw material, reduced pollution, and workability of the present invention is excellent, good endurance, maintenance-free, cost is low, thereby has good social benefit and economic benefit.
The specific embodiment: job practices of the present invention is divided three layers or two-layer the construction, and bottom is a poor concrete, and the middle level is the graded broken stone layer, and the upper strata is the high compact bituminous concrete; Its upper strata high compact bituminous concrete is the theoretical and theoretical breeze replacing section pitch of using of particle parcel according to pocket, and the mixing ratio by weight after the displacement is that the also available coarse sand of (kg/m3) rubble 1276-2146, aggregate chips replaces 518-680, the also available flyash of fine sand to replace 120-280, pitch 80-155, ground blast furnace slag 0-60; Particle diameter is than being rubble: aggregate chips 〉=3.15, and aggregate chips: fine sand 〉=3.15, fine sand: ground blast furnace slag 〉=3.15, cumulative volume are the 1050-1080 liter, solid density is 1580-2880/m3; Its production method is above-mentioned material to be mixed stir roller-compaction.
Described bottom poor concrete, mixing ratio by weight are that the also available coarse sand of (kg/m3) rubble 1276-2146, aggregate chips replaces 518-680, the also available flyash of fine sand to replace 120-280,32.5 class g cement 50-295; Particle diameter is than being rubble: aggregate chips 〉=3.15, aggregate chips: fine sand 〉=3.15; Its production method is above-mentioned material to be mixed stir roller-compaction.
Described middle level graded broken stone layer, mixing ratio by weight are that the also available coarse sand of (kg/m3) rubble 1276-2146, aggregate chips replaces 518-680, the also available flyash of fine sand to replace 120-280; Particle diameter is than being rubble: aggregate chips 〉=3.15, aggregate chips: fine sand 〉=3.15; Its production method is above-mentioned material to be mixed stir, roller-compaction, and this layer also can.
Adopt " pocket " theoretical and particle parcel theory in the present invention." pocket " theoretical its principle is that pocket itself does not have compressive strength, and dry grain does not have compressive strength yet; When we pack into pocket and make grain closely knit of grain, the loading pocket shows good anti-pressure ability, and grain is closely knit more, the compressive strength of loading pocket is higher; In concrete, the gelling thing is the effect of effect-immediate shipment grain pocket that hoop is reined in thing to what gathered materials, is grain in the pocket and gather materials; In " pocket " theory, concrete strength is relevant with two factors, i.e. the packing density that the hoop of gelling deposits yields is reined in power and gathered materials.Theoretical its principle of particle parcel is gathered materials for i.e. thin one-level and is used for the thick one-level of parcel and gathers materials, make can gluing between gathering materials together.That is to say that aggregate chips is filled into by rubble to be piled up in the space that forms; Breeze is filled into aggregate chips and piles up in the space that forms; Gathering materials has minimum porosity, has maximum packing density, produces maximum intensity, maximum durability.
In order to guarantee the high strength requirement of high dense asphalt concrete, my door is theoretical according to " pocket " theory and particle parcel, can produce minimum porosity in gathering materials, and guarantees suitable particle diameter ratio and the part by weight of material, thereby formed high strength, high durable high dense asphalt concrete.
High dense asphalt concrete is meant 7 days following high strength asphalt concretes of the above 10MPa of intensity 1MPa.Bituminous concrete according to above match ratio preparation designs density in theory and can reach 2580-2880/m3, and construction density can reach 2500-2800/m3, and the homogenieity permeability resistance durability of bituminous concrete and rutting resistance all obviously improve.
