Performance of asphalt concrete with plastic fibres


Performance of fibre-reinforced high-strength concrete

fibres is a good way to overcome the brittleness of plain HSC. Fibre-reinforced concrete may be defined as composites of concrete with the incorporation of discrete, discontinuous fibres. In ordinary concrete, strength will decrease abruptly when initial cracking occurs. The weakest link is usually at the interfacial

Field Trials of Plastic-and Latex-Modified Asphalt Concrete

The poor performance and premature failures of some asphalt paving mixtures in this country have led many field engineers to believe that asphalt cements, and thus asphalt concrete mixtures, have changed over time. Many engineers and field personnel attribute poor pavement performance to the oil com­

Permeable Pavement: The Pros and Cons You Need to Know

Permeable pavement is a pavement type with a porous surface that is composed of concrete, open pore pavers or asphalt with an underlying stone reservoir. Also considered as green pavement, it allows water to run through it rather than accumulate on it or run off of it. The precipitation and water get stored in the reservoir from where it slowly infiltrates the soil below or is drained via a

Concrete Roof Tiles - Portland Cement Association

Concrete tiles have grown more competitive in price, due in part to the rising costs of petroleumbased products such as asphalt shingles. Compared to unsightly weather-beaten asphalt shingles and their replacement costs, concrete roof tiles offer an affordable and economical alternative, especially when considering their life cycle cost.

Investigation on Reinforced Mechanism of Fiber Reinforced

Short fibers have been widely used to prepare the fiber reinforced asphalt concrete (FRAC). However, internal interactions between fiber and other phases of asphalt concrete are unclear although experimental methods have been used to design the FRAC successfully. In this paper, numerical method was used to investigate the reinforced mechanism of FRAC from microperspective. 2D micromechanical

CHAPTER FOUR Asphalt Additives and Modifiers

Warm-mix asphalt treated mixtures produced low initial tensile strengths, but the strength of these mixtures improved with time (Watson et al. 2013). An important material property that influences the performance of an asphalt mixture is the surface free energy of the asphalt binder and the aggregate.

Viscoelastic Properties Research of Sisal Fibre Asphalt

Asphalt concrete is a typical complex of viscous, elastic and plastic.So the raw materials should be fully considered, such as asphalt, aggregate, filler, etc, when research to viscoelastic. Viscoelastic can influence various properties, even to service life of the road and its performance. Therefore, if can improve the viscoelastic properties, it will have a lot of influence to asphalt concrete.
