Embodiment 1

[0031] Embodiment 1: Each raw material is calculated by weight ratio, 52 parts of asphalt AH-90, 522 parts of gravel, 218 parts of dredging mud ceramsite, 155 parts of sand, and 53 parts of limestone slag.

[0032] Among them, the dredging mud ceramsite satisfies the following properties: cylinder compressive strength > 6MPa, water absorption 700, particle size 5-16mm, particle shape coefficient ≤ 1.15, softening coefficient ≥ 0.85, firmness (according to Mass loss) < 5%, boiling mass loss ≤ 4%, ignition loss ≤ 4%, sulfide and sulfate content (calculated as sulfur trioxide) < 0.5%, mud content < 1.0%, organic matter content is not deep In the standard color, Los Angeles wear loss <28%, polishing value (BPN) <55, adhesion to asphalt ≥3, dredged mud ceramsite surface texture is coarse, and tightly combined with asphalt.

[0033] First, pretreatment of raw materials mainly refers to the preheating treatment of dredged mud ceramsite. The preheating temperature is the same as that...

Embodiment 2

[0037] Embodiment two: each raw material is calculated by weight ratio, gets 54 parts of petroleum pitch AH-90, 511 parts of crushed stones,

[0038] There are 254 parts of dredging mud ceramsite, 126 parts of sand, 47 parts of limestone slag, and 8 parts of cement.

[0039] The preparation of ceramsite asphalt concrete was carried out according to the steps of Example 1.

Embodiment 3

[0040] Embodiment three: each raw material is calculated by weight ratio, gets 58 parts of petroleum pitch AH-90, 456 parts of crushed stones,

[0041] 268 parts of dredging mud ceramsite, 160 parts of sand, 58 parts of limestone slag.

[0042] The preparation of ceramsite asphalt concrete was carried out according to the steps of Example 1.

[0043] The performance index parameters of the dredged mud ceramsite concrete prepared in the above three embodiments are shown in the table below.

[0044] Performance

[0045] It can be seen from the various performance indicators of the asphalt concrete in the above table that the dredged mud ceramsite asphalt concrete has excellent performance, fully meets the road performance requirements, realizes waste utilization, saves natural resources, is green and environmentally friendly, and can bring great benefits. economic and social benefits.

Abstract

This invention relates to a bitulith composed with dredge mud ceramicite, and its production method. The raw materials of this inventive product are: asphalt, ballast, dredge mud ceramicite, sands and fillings. The production method comprises procedures of: preheating the dredge mud ceramicite, mixing with various kinds of raw materials in proportion in blending equipment, then mixing them evenly, loading the same into paver and then spreading, rolling. This invention solves the problems of the consumption of non-regeneration resources in prior art method with advantages of: low cost, resources-saving, environmental-protection.

Description

technical field [0001] The invention relates to a road building material, in particular to a dredging mud ceramsite asphalt concrete for roads and a preparation method thereof. Background technique [0002] Asphalt concrete pavement is one of the main types of road surface because of its fast open traffic and comfortable driving. However, there are some disadvantages in asphalt concrete pavement: First, it is difficult to improve the anti-rutting ability at high temperature. At high temperature, rutting is formed at the wheel track, which is the most common disease of asphalt concrete pavement; It has been very common. Due to poor durability, the life of asphalt pavement is difficult to reach the design life; thirdly, the water stability is not good; secondly, the anti-skid performance of asphalt pavement is average, and the anti-skid performance after rain is poor; finally, asphalt concrete The sound absorption effect of the road surface is average. As mentioned above, th...
