Analysis On Causes For Water-damage Of Highway Asphalt Pavement And Research On The Maintenance Countermeasure

The author combine the general phenomenon of Water-damage of Jing-Qin Highway, adopting to an investigation method of Random sampling, comprehend the The pavement structure and Running status of all the Jing-Qin Highway , overall analysis water damage creation reason,development process and function mechanism. on the basis of systematic investigation and study, develop mechanical analysis for the pavement structures status, further analysis the development status and reasons of pavement structures failure after the water-damage creation .Based on the well known research achievements , Combined with the test results and checking results , from the structure,material,natural environment etc. summary the various factors of influencing on the asphalt pavement water-damage, maintenance countermeasure is put forward express particular water-damage expres origin, development stage,,disease of degree. Express the water-damage typical disease and harm degree , develop paving test section for different maintenance countermeasure and the analyse the performance, Evaluating the using effects of defferent maintenance plan, summary the suitable maintenance plan.
