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

A kind of constructing roadbed with solidifying silt particle material and preparation method thereof
Technical field
The invention belongs to a kind of highway subgrade material, specifically is a kind of relating to based on coastal region a large amount of hydraulic fill sand and mud, and a kind of highway subgrade material that the admixture small number of curing agents is made belongs to highway structure material technology field.
Background technology
At present, the fast development of coastal region Coast Expressway, motorway has design driving speed per hour height, characteristics such as require vehicle to travel 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, intensity is low, and water is steady, the freeze thawing poor-performing, and construction quality is 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, the intensity height, simultaneously the new road base layer material of excellent road performance is our urgent problem.
Summary of the invention
Purpose of the present invention will solve the deficiencies in the prior art exactly, provides a kind of constructing roadbed with solidifying the silt particle material, and mainly based on a large amount of hydraulic fill sand in coastland and mud, the admixture small number of curing agents is prepared from this roadbed material.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.
