A simple review of soil reinforcement by using natural and synthetic fibers

Interfacial shear strength of fiber reinforced soil

Fiber reinforcement effects on sand considering a wide cementation range

This report presents information on the characterization of cementitiously stabilized layers and the properties that influence pavement performance. It also contains recommended performance-related procedures for characterizing these layers and performance-prediction models for incorporation into the mechanistic–empirical pavement analysis methods. Individual chapters highlight pavement distresses of hot-mix asphalt pavements and concrete pavements, laboratory tests and model development, and model calibration. The material contained in the report will be of immediate interest to state materials, pavement, and construction engineers and others involved in the different aspects of pavement design and construction.

Strength and mechanical behavior of short polypropylene fiber reinforced and cement stabilized clayey soil

The invention discloses a dust preventing agent, which includes components of water or deionized water, acrylic acid, methacrylate, acrylamide and initiator, wherein proportion of each component is: 90-120 quotient of water or deionized water; 7-12 quotient of acrylic acid or 2-4 quotient of methyl methacrylate, ethyl methacrylate or propyl methacrylate; 2-4 quotient of acrylamide; 0.05-0.1 quotient of persulfate initiator; 0.03-0.05 quotient of crosslinking agent and 5-10 quotient of neutralizer which are also added. The dust preventing agent is thick liquid and is used after diluting, when being sprayed, the dust preventing agent can adsorb dust in air and combine with granule on ground surface to form film structure, and the dust preventing agent also possesses water-absorbing quality and water-retention property to prevent dust flying and clean air.

Dust preventing agent and preparation method thereof

The present invention relates to a short fibre reinforced lime soil ground base treatment method. It is characterized by that it makes the short fibre and lime be mixed in the engineering soil so as to improve the engineering property of soil, and can be used for making ground base treatment. The fibre content is 0.05-0.5% of dried soil weight and the lime content is 1-10% of dried soil weight, the fibre length is 2mm-30mm. Said soil in which the short fibre and lime are mixed is undergone the processes of stirring, stacking and rolling so as to form the invented short fibre reinforced lime soil ground base.

The invention discloses an ecological soil stabilizer, which includes: water or deionized water of 180-220 weight quotient; comonomer 1: vinyl acetate of 100-140 weight quotient; comonomer 2: methyl methacrylate or with comonomer 3 of 5-20 weight quotient; comonomer 3: acrylate of 5-20 weight quotien; polyvinyl alcohol of 8-15 weight quotient; emulsifier sodium dodecyl sulfate or with OP of 2-4 or each of 2-4 weight quotient; initiator (persulfate) of 0.5-2 weight quotient. The invention possesses good environment fitness, accords with basic requirement of ''environment sign product technique requirement'' (HJB-2004-94), and is environment friendly product. The product is emulsion, can obviously increase water stability and strength of soil particles, can reinforce scour resistance of soil, and simultaneously possesses moisture preservation function to accelerate plant grow.
