When installing pavers over top of an existing asphalt of concrete pad, there are three installation options: sand set, bituminous set, and mortar set. [1] Due to rising oil prices, these methods are often less expensive than an asphalt overlay and last three times longer in addition to providing a greener, more sustainable solution. [2] [3] [4]
Asphalt batch mix plant A machine laying asphalt concrete, fed from a dump truck. Asphalt concrete (commonly called asphalt, [1] blacktop, or pavement in North America, and tarmac or bitumen macadam in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams.

Asphalt road being milled in preparation for repaving. Pavement milling (cold planing, asphalt milling, or profiling) is the process of removing at least part of the surface of a paved area such as a road, bridge, or parking lot. Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal.
A road of such material is called a "metalled road" in Britain, a "paved road" in Canada and the US, or a "sealed road" in parts of Canada, Australia and New Zealand. [ 48 ] A granular surface can be used with a traffic volume where the annual average daily traffic is 1,200 vehicles per day or less.
Chip seal products can be installed over gravel roads to eliminate the cost of grading, road roughness, dust, mud, and the cost of adding gravel lost from grading. Adding chip seal over gravel is about 25% of the price of resurfacing with asphalt, $170,000 for a 4-mile project done in Minnesota [6] compared to $760,000 had it been redone with ...
Mastic asphalt is a type of asphalt that differs from dense graded asphalt (asphalt concrete) in that it has a higher bitumen content, usually around 7–10% of the whole aggregate mix, as opposed to rolled asphalt concrete, which has only around 5% asphalt. This thermoplastic substance is widely used in the building industry for waterproofing ...
In some parts of the United Kingdom the standard design life is 40 years for new bitumen and concrete pavement. Maintenance is considered in the whole life cost of the road with service at 10, 20 and 30-year milestones. [56] Roads can be and are designed for a variety of lives (8-, 15-, 30-, and 60-year designs).
These machines are used in application areas including structural and civil engineering, road construction, agriculture, gardening, landscaping, municipal works, recycling and industrial projects. The group comprises the three brands Wacker Neuson, Weidemann and Kramer as well as affiliates and production plants.
