Brock Ridge Gets A New ‘Green’ Surface
With more and more emphasis on recycling and green projects, Brock Ridge Road is, literally, on the cutting edge.
The roadway is currently undergoing a process that involves Asphalt Recycling and Reclaiming (ARRA), a new method.
It involves full depth reclamation, a technique in which the full pavement section and a predetermined portion of the underlying materials are uniformly crushed, pulverized, or blended, resulting in a stabilized base course. Further stabilization may be obtained through the use of available additives.
By addressing the entire pavement section, full depth reclamation is able to correct delinquent cross sections, increase the load-bearing strength of the base, and utilize 100 percent of the existing materials. Substantial savings can be realized while meeting environmental goals.
Equipment for the process includes traveling hammer-mills, crushing units, stabilizers, or a combination of these types of machines.
Critical to the success of this process is the preliminary testing to establish design criteria for gradation, residual asphalt content, and the possible use of additives. This reconstruction technique requires a wearing surface of a thickness to be determined by an analysis of traffic data.
Contracted by Chesapeake Energy, Zell Consultants are repaving Brock Ridge Road, along with Force Construction. A visit to the site showed what is involved in this process.
The old road was clearly gone in the pulverizing process and then compacted on the roadway. A person using a nuclear density gauge was checking after compression of the road after the machinery went through. According to the person doing the testing, a reading of 98 to 102 percent of compression is the goal. This has to be accomplished before more road work can proceed.
A mixture of Portland cement approximately eight inches deep was laid down on the road to make the base needed. After the cement base is cured, then an asphalt layer will cover the surface.
Big rig trucks with heavy loads contracted by Chesapeake will be continuing to travel the Brock Ridge road to their destination drilling rigs in Wetzel County. With this new reconstruction of the road, it will be able to handle the weight loads, according to an employee of Zell Consultants.
A employee of Flex Tech Resources told of how the road, when completed, if good weather continues, will be cured in two to five days. After this curing process, then the road will be open again for access.
Environmentalists, taxpayers, and legislators will be pleased to know that this new way to repave roads is responsible for keeping literally millions of tons of asphalt out of North American’s landfills.
