Learn MorePermeable 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

It is waterproof, permanent, flexible, and self-sealing. FIBRE EXPANSION JOINT is composed of cellular fibers securely bonded together and uniformly saturated with asphalt
Learn MoreMembrane roofing is often used on commercial flat roofs. Roof membranes discussed in this article include built-up asphalt (tar and gravel), modified bitumen, and single-ply membranes like EPDM, PVC, TPO, and KEE. We also cover spray applied foam and liquid roofing options.
Learn MoreConcrete 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.
Learn MoreA fibre reinforced asphalt concrete used for pavement of road features that the acrylic fibres (0.2-0.3 wt.%) are used to increase the adhesion between aggregate and asphalt, resulting in high resistance to high temp track and low-temp cracking, high stability, and no plastic deformation.
Learn MoreRutting test, residual stability test and freeze-thaw split test were used to measure the properties of asphalt mixture with different graduation and same mixing amount of fibers, the results were analyzed to obtain the influence of graduation types in the road performance of fiber-reinforced asphalt mixture. The results showed as follows: fibers could obvious improve the high temperature
Learn MoreUse of Waste Plastic in Concrete Mixture as Aggregate Replacement. One of the environmental issues in most regions of Iran is the large number of bottles made from poly-ethylene terephthalate (PET) deposited in domestic wastes and landfills. Due to the high volume of these bottles, more than 1 million m3 landfill spaces are needed for disposal
Learn MoreShort 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

Learn MoreWarm-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.
Learn MoreSpecification for supply of recycled materials for pavements, earthworks and drainage (PDF 556KB) is an industry-wide specification for the supply and use of recycled materials in local roads, pavements and civil works. It outlines a variety of uses for recycled aggregates including: road base material suitable for a range of traffic conditions.
Learn MoreAsphalt 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.
