Bituminous pavement in-situ regeneration disposal method, test piece preparation method and test piece evaluation method
The invention discloses a treatment method for in-situ regeneration of an asphalt pavement, which mainly adopts an in-situ regeneration rod with a composite regeneration agent to be placed in the asphalt pavement to be repaired, and adopts a heating method to enable the composite regeneration agent to react with waste asphalt, so as to complete in-situ repair of the asphalt pavement. The transportation cost is reduced, energy is saved, the construction period is shortened, and the influence on the environment is reduced; the invention further discloses test piece preparation and test piece evaluation, an in-situ regenerated asphalt pavement is sampled and tested, a test piece sample and a reference sample are subjected to a softening point test, a PG classification test, a ductility test and a low-temperature bending beam rheological test, and the softening points, the ductility, the rutting factors and the creep rates of the test piece sample and the reference sample are accurately known. And comparing to obtain the quality and the performance of the regenerated asphalt, and calculating the diffusion condition of the composite regenerant to obtain the regeneration effect of the regenerated asphalt pavement.
本发明公开了一种沥青路面原位再生的处置方法，主要是采用带有复合再生剂的原位再生棒置于需要修复的沥青路面内，并采用加热的方法使得复合再生剂与废料沥青进行反应，从而完成了沥青路面的原位修复，减少了运输成本、节约了能源、缩短了工期，并降低了对环境的影响；还公开了测试件制备和测试件的评价，对原位再生的沥青路面取样测试，将测试件样品与参照样品经过软化点试验、PG分级试验、延度试验和低温弯曲梁流变试验，准确得知测试件样品与参照样品的软化点、延度、车辙因子及蠕变速率，且进行比较，得到再生沥青质量和性能，再通过计算复合再生剂的扩散情况，进而得知再生沥青路面的再生效果。
