Foreword
I engaged in road maintenance for many years, the use of old asphalt recycling technology for solving asphalt pavement pit and there were problems with the patch. The use of the site excavated site mixing old pavement mix, paving, to avoid loss of material temperature mixing materials transportation distances, saving transportation costs; old materials renewable heating with gas, reducing environmental pollution; small amount production, without the use of large-scale mixing equipment, make up a large-scale conventional hot-mix equipment not timely and low-volume production defects, reducing the mix of cost, as the dig pit road opened up a new road, highway maintenance is an economical and practical new technology.Concrete Roller Screeds Curb Forming

Two questions raised Pothole Repair
1. Regeneration mixes at different temperatures temperature adaptability, production quality primary stability. Especially in the province Hercynian area larger temperature difference between day and night, for the stability of asphalt mixture is a more prominent issue. Able to work out a set of more suitable technical plateau characteristics is a long and arduous problems.Crack Sealing Road Maintenance

2. Direct economic and social benefits assessment. Asphalt recycling process on, we have to consider not only direct economic mix itself brings, but also consider the social benefits, once a lot on asphalt abandoned on the grass and along the beaches, causing environmental pollution and waste of resources, destruction of the province had a very fragile ecological environment has important implications for this assessment of social benefits.
3. Resolved by the small size and small-scale production into large-scale production program in order to replace the conventional hot-mix and mechanical equipment is not economical issues do not apply, and solve repeated unlucky asphalt gravel materials and other complex process, in order to solve minor repairs Wabu points, lines long, difficult to manage and operate other problems, provide a viable measures.Comprehensive Repair Material Work Characteristics

4. Old asphalt pavement recycled materials The main technical indicators test. As Marshall stability, aggregate ratio, density and asphaltene content of the old asphalt pavement, stone grading tests and other indicators. Because after a long time have different degrees of aging and driving sun and rain, the original asphalt pavement, for its various technical indicators are not able to adapt to the requirements of regeneration, how to determine the technical specifications and promoted in practical application is required focus of the study.Best Road Maintenance Machinery - Doan Machinery
