Asphalt milling, paving & compaction

Demand for geosynthetics in the United States alone is projected to increase 4.4% per year through to 2010 to more than 727 million m². Geosynthetics, used worldwide in the highway sector for strengthening, include geotextiles, geomembranes, geonets, geogrids, geosynthetic clay liners, preformed geocomposites, geocells and geofoams. The US advances will be fuelled by a recovery in nonbuilding construction. Additionally, geosynthetics will continue to increase their use in a wider range of applications

More sophisticated compaction technologies are now coming to market, offering a wide range of benefits to users While asphalt paving techniques vary widely between North America and Europe, there is greater commonality in the compaction methods required. New developments in compaction rollers are offering contractors using both North American and European style paving techniques major gains in quality. According to Robert Horan, a regional engineer for the US-based Asphalt Institute, intelligent compact

Ferocious daytime temperatures can provide a tough challenge to construction firms working in desert conditions in Egypt's south. Despite the high daytime temperatures however, Egyptian contractor Orascom has managed to complete an airport project on budget and ahead of schedule, while meeting the client's tight specifications. The firm has just completed the project to revamp Suhag Airport in the south of the country. This airport now features a new runway, taxiways and aircraft hard standing, as well as n

Jonyang is a joint venture owned by Guizhou Guiyang Industrial Investment Holding Company and Singapore Technologies Kinetics (ST Kinetics), with excavators forming the main sales focus.

Effective compaction control is one of a series of technical innovations boosting performance efficiency – Mike Woof writes. Maximising compaction efficiency can be a major cost factor on construction projects. Both for soil and asphalt compaction sectors, the risk from leaving an area under or over-compacted is substantial.

World of Asphalt 2012 and the co-located AGG1 Aggregates Forum & Expo will be the largest in the history of the two events.

The Wirtgen Group is developing its manufacturing facilities outside of Germany. The company has extensive operations in Brazil and China and has now opened a new plant in India, which has started production already. Joint president Stefan Wirtgen said, “The first machine we made was a Hamm compactor. It is specially developed for the Indian market.”

This is the final section of a three-part series about preventive maintenance for pavements. Written by Alan S. Kercher, P.E., Kercher Engineering, Inc We practice preventive maintenance in our everyday lives and possibly with agency equipment such as dump trucks and backhoes, but when it comes to maintaining our roadways, most agencies will always defer repairs until the pavements have failed, resulting in very expensive repairs. This article will provide some guidance to help an agency make the switch fr

Several aspects factor into choosing the proper concrete dowel drill - Randy Stevens. The concrete paving industry has seen significant changes to dowel drilling equipment over the years. Many years ago only hand-held models existed and when the first hydraulic drills were launched over 30 years ago, these increased production and reduced labour needs. Since that time pneumatic drills, have come to market and these are driven by air compressors, which are common on many worksites while the units also have l
