What Does Pozzolanic Mean? Pozzolanic refers to a type of material which, when combined with water and lime, forms a cement-like material known as ‘pozzolana’. This can be an artificial material derived from volcanic ash or industrial by-products, or a natural material like diatomaceous earth. The pozzolana cement can be used for various construction purposes […]
What Is A Lime Mortar? Lime mortar is a mixture of lime, an aggregate such as sand, and water, used in construction. It was used by the ancient Egyptians and Greeks and in ancient Indian and Roman structures. It has been used less in recent times due to the widespread adoption of Portland cement which […]
What Is A Wrought Iron? rought iron is a type of iron alloy that has a very low carbon content and is known for its malleability, ductility, and resistance to corrosion. It is made by hammering, rolling or otherwise working iron while it is hot enough to expel molten slag, which gives it a grainy […]
What Are Mortar Joints? Mortar joints are seams between two masonry blocks or bricks which are filled with mortar, a mixture of cement, sand, and water. The mortar provides a strong bond between them and prevents water from seeping into the walls, providing stability and insulation. Mortar joints play an important role in the overall […]
What Is A Frost Weathering? Frost weathering is the process by which water freezing in ice causes mechanical weathering, which can take various forms, such as frost shattering, frost wedging, and cryofracturing. It can occur over short or long periods and at different scales, from breaking apart individual mineral grains to shattering large boulders. This […]

What Is Hot In-Place Recycling? Hot In-Place Recycling is a method for repairing damaged pavement by heating and scarifying the existing asphalt, adding a recycling agent, and laying the new mixture over the old surface. This process is used to fix surface issues, rather than problems with the underlying structure. After the recycled asphalt has […]
What Is Cold In-Place Recycling? Cold In-place Recycling (CIR) is a process that rehabilitates a road using existing pavement materials on-site. These materials are mixed together without heat using milling, crushing, or planing techniques. Virgin aggregate or recycling agents may be added to the reclaimed asphalt pavement (RAP) material before it is compacted into place. […]
Hot In-Place Recycling Vs. Cold In-Place Recycling Hot In-Place Recycling (HIPR) and Cold In-Place Recycling (CIPR) are two techniques used to extend the life of a pavement. HIPR consists of heating the asphalt surface, ripping, milling and mixing new asphalt material into the existing pavement structure while it is still hot. The process will generally […]
