Embodiment 1

[0044] Embodiment 1: see Fig.], 2,9 0

[0045] A new type of road, which consists of a pavement compacted base 1, poured on the pavement compacted base 1, with a thickness of 220 mm and a single row of holes 4 inside (the diameter of the holes is about 100 mm. The distance between the holes is 1.3-1.5 times the diameter) The hollow concrete layer 2 is composed of;

[0046] The hollow concrete layer 2 is composed of cementitious materials (70% (weight%, the same below) slag, 15% converter steel slag, 10% admixture (including 2% quicklime, 8% cement clinker), 5% activator (including 2% aluminum mud, 3% Glauber's salt ore) mixed and ground to fineness (passed through O.08 mm square hole sieve), less than 2% composition), 1mm steel slag (or coarse sand), crushed stone, water press The ratio of the prior art is mixed, the single row of holes is molded and cast directly, and the 28-day compressive strength is greater than 40MPa, and the flexural strength is greater than 8Mpa....

Embodiment 3

[0050] Embodiment 3: see Figure 6 , 9 .

[0051] A new type of road, the base layer 1 is compacted from the road surface, poured on the compacted base layer 1 of the road surface, the thickness is 300 mm, and there are double rows of holes 4 and small holes 8 (the diameter of the large hole is about 80-120 mm, and the diameter of the small hole 8 It is composed of hollow concrete layer 2 of 50-80mm and 1;

[0052] The hollow concrete layer 2 is composed of cementitious materials (5.8% slag, 1.0% electric furnace steel slag, 1.5% phosphorus slag, 10% admixture (including 2% quicklime, 8% cement clinker), 7% activator ( Containing 1% aluminum mud, 4% Glauber's salt ore, 2% calcined alum ore) mixed and ground to a fineness (passed through a 0.08mm square hole sieve) less than 2% composition), less than 1mm steel slag (or coarse sand), Gravel and water are mixed according to the proportion of the existing technology, and the double rows of holes are molded and cast dire...

Embodiment 4

[0053] Embodiment 4: see Figure 8 , 1 0.

[0054] A new type of road, comprising pavement compacted base 1, prefabricated concrete hollow slabs 5 (each slab length can be 2500-3500 mm, width can be 900-1500 mm, thickness can be 1 20-180 mm) of the prefabricated concrete hollow slab, and the concrete surface layer 6 with a thickness of 60-120 mm poured on the prefabricated concrete hollow slab; and the total thickness of the prefabricated concrete hollow slab and the concrete surface 2 0-300mm;

Abstract

The invention provides a novel road and construction method thereof, which is characterized in that the novel road is composed of a pavement compacting base, a poured hollow concrete layer or a spliced prefabricated concrete hollow board layer and a concrete surface layer, and a fine-stone concrete under layer can also be casted between the pavement compacting base and the hollow concrete layer or the prefabricated concrete hollow board layer; the cement for the road provided by the invention can employ cement of prior art, and a novel gel material which is prepared by grinding mixed powder containing industrial waste residues and additives and exciting agents is preferentially employed. By using the invention, the construction progress is obviously accelerated, and the construction cost is reduced, and the invention has substantial economic benefit and social benefit.

Description

technical field [0001] The invention belongs to a road structure and a construction method, and relates to a novel road and a construction method thereof. Background technique [0002] Existing roads are generally composed of two layers of concrete with a thickness of 240-250 mm. They are built with 400# concrete, poured twice, and firmly bonded with steel bars between layers. This way, the construction progress is slow and the cost is high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a novel road with fast construction progress, low cost and high quality and its construction method. [0004] The content of the present invention is: a novel road, comprising: pavement compacted base, which is characterized in that it also includes: a hollow concrete layer poured on the pavement compacted base, the thickness of the hollow alkali layer is 220-300mm, anti- The compressive strength is 40-5...
