Abstract
The invention belongs to a highway roadbed material, in particular relates to a highway roadbed material prepared from dredger sand and silt in coastal regions and a small amount of curing agent, and belongs to the technical field of highway building materials. The highway roadbed material comprises the following main components in percentage by weight: 35 to 75 percent of dredger sand, 15 to 55 percent of silt and 5 to 10 percent of curing agent, wherein the curing agent comprises the following components in percentage by weight: 90 to 95 percent of cement clinker, 3 to 6 percent of zeolite,0.5 to 2 percent of polyacrylamide, 0.2 to 1 percent of polyving akohol, 0.2 to 1 percent of vinylite, 0.2 to 1 percent of acrylic ester and 0.2 to 1 percent of sodium carboxymethylcellulose. The new highway roadbed material for coastal regions meets the environmental protection requirement, and has low cost, high strength and good road performance. When 5 percent of curing agent is doped, the unconfined compressive strength is improved to 1.59Mpa/7 days from 0.8Mpa/7 days of semi-rigid two lime broken stone serving as the highway base course material, and after the highway roadbed material is cured for 28 days, the unconfined compressive strength is improved to 2.04Mpa; and when the mass loss is 5 percent, the freeze-thaw cycle times is 28.
Description
Technical field
The invention belongs to a kind of highway subgrade material, specifically is that a kind of to relate to coastal region a large amount of hydraulic fill sand and mud be main, and a kind of highway subgrade material that the admixture small number of curing agents is processed belongs to highway structure material technology field.
Background technology
At present; The coastal region Coast Expressway is fast-developing; It is high that motorway has design driving speed per hour, requires characteristics such as vehicle ' steady, smooth and easy and working life is long, for satisfying these requirements; That road is provided with is must globality strong, bearing capacity is high, rigidity is big, good stability and firm basic unit is arranged, to bear and to transmit traffic load.And the natural condition around the coastal high speed are harsh challenges for the construction quality of highway; Wash away and the fluctuation meeting of tidal level of seawater produce detrimental action to the stability and the security of embankment, and aggressiveness villaumite and vitriol etc. become branch that road base layer material and appendicular weather resistance are caused remarkable harm in the seawater.
Adopt good rubble, pseudo-ginseng soil or the cement of grating to add flyash and add these traditional highway subgrade materials such as sandstone aggregate, cost is higher, and intensity is low; Steady, the freeze thawing poor-performing of water, construction quality be difficult to guarantee, particularly along with the propelling of sustainable development target; Cut into a mountain and get rubble and will be under an embargo, therefore, it is low to develop a kind of cost; Intensity is high, and the new road base layer material of excellent road performance is our urgent problem simultaneously.
Summary of the invention
The object of the invention is exactly the deficiency that will solve prior art, provides a kind of constructing roadbed using to solidify the silt particle material, and this roadbed material is main with a large amount of hydraulic fill sand in coastland and mud mainly, and the admixture small number of curing agents is prepared from.This roadbed material is gathered materials on the spot, and turns waste into wealth, and compliance with environmental protection requirements greatly reduces road cost, has improved construction quality.
Component of the present invention and content is (by weight percentage, down together) as follows:
Hydraulic fill sand 35-75%
Mud 15-55%
Solidifying agent 5-10%
Wherein, hydraulic fill sand is a native state, and maximum particle diameter is less than 0.5mm, and silt content is less than 10%.Mud is seashore mud, high-moisture, and between 50%-70%, liquid limit 40-45%, plastic limit 10-15% belongs to stream and moulds state (said all by weight percentage).
Wherein the component of solidifying agent and content are following:
Cement clinker 90-95%
Zeolite powder 3-6%
SEPIGEL 305 0.5-2%
Z 150PH 0.2-1%
Vinylite 0.2-1%
Propenoate 0.2-1%
Xylo-Mucine 0.2-1%
Wherein, cement clinker is a Portland clinker, and SEPIGEL 305 is an anionic, and solid content is (by weight percentage) more than 90%.This kind is constructing roadbed with solidifying the silt particle material preparation method; It is characterized in that 1. the preparation method of solidifying agent is: SEPIGEL 305, Z 150PH, Vinylite, propenoate, Xylo-Mucine mix in proportion; Add then in the cement portland cement clinker and zeolite powder after levigate; Place grinding machine for grinding, grinding fineness reaches 350-900m
2More than/the kg.2. hydraulic fill sand and mud are put into stirred vessel by a certain percentage, stir.3. will put into step stirred vessel 2. from a certain amount of solidifying agent that step obtains 1.,, process roadbed material with mixture uniform mixing wherein.
This kind roadbed material of our invention; Measure through national building materials test center, solidifying agent can make unconfined compression strength make the road base layer material than with " semi-rigid two-ash broken stones " and bring up to 1.59Mpa/7 days from 0.8Mpa/7 days when volume 5%; After the health 28 days; Its unconfined compression strength increases to 2.24Mpa, and mass loss is 5% o'clock, and freezing-thawing cycles reaches 28 times.Simultaneously, its water stability can be good.
The present invention can substitute the portion water cement-stabilizing broken stone in practical application, make the road construction work direct investment reduce 20%-40%.
