就地?zé)嵩偕哼@種再生法就是利用瀝青路面熱再生聯(lián)合機(jī)組來就地完成瀝青路面的熱再生修復(fù)。原有路面材料100％地利用，不需要搬運(yùn)廢料及廢棄物堆放場地，可減少環(huán)境污染；能夠改變個別 的混合料成分，以便給定瀝青 混合料的最佳配比；可以快速就地再生，并隨著工程進(jìn)度開放道路交通，對交通干擾最小，現(xiàn)在國外應(yīng)用很廣。
On site geothermal regeneration: This regeneration method utilizes a combined unit of asphalt pavement thermal regeneration to complete on-site thermal regeneration and repair of asphalt pavement. The original road materials are 100% utilized, and there is no need to handle waste materials or waste storage sites, which can reduce environmental pollution; Being able to change individual mixture components in order to give the optimal ratio of asphalt mixtures; It can quickly regenerate on site and open up road traffic as the project progresses, with minimal traffic interference. It is now widely used abroad.
瀝青路面的現(xiàn)場熱再生就是原有瀝青路面再生100％在現(xiàn)場完成，先加熱軟化原瀝青路面以便于耙松，然后將耙松的瀝青路面充分拌和，隨后進(jìn)行攤鋪碾壓。
The on-site thermal regeneration of asphalt pavement refers to the 100% completion of the original asphalt pavement regeneration on site. The original asphalt pavement is first heated and softened to facilitate loosening, and then the loosened asphalt pavement is fully mixed, followed by paving and rolling.
瀝青路面的老化主要是其瀝青中輕質(zhì)組分減少，石料的少量損失，瀝青路面就地?zé)嵩偕ㄟ^添加再生劑調(diào)節(jié)舊瀝青路面中老化瀝青的化學(xué)組分，來恢復(fù)老化瀝青的性能，同時補(bǔ)充少量新拌瀝青混合料來調(diào)整原有瀝青混合料級配，以達(dá)到瀝青路面再生效果。
The aging of asphalt pavement is mainly due to the reduction of lightweight components in its asphalt and a small amount of loss of stone materials. The thermal regeneration of asphalt pavement is achieved by adding regenerants to adjust the chemical components of aging asphalt in the old asphalt pavement, in order to restore the performance of aging asphalt. At the same time, a small amount of fresh asphalt mixture is added to adjust the grading of the original asphalt mixture, in order to achieve the effect of asphalt pavement regeneration.
新瀝青混合料和再生劑按需要比例加入。通常新瀝青混合料控制在再生混合料質(zhì)量的30％以內(nèi)。各種材料的添加率根據(jù)原瀝青路面性能分析及其實驗室配合比設(shè)計，并符合相應(yīng)的混合料規(guī)范而確定。
Add new asphalt mixture and recycling agent in proportion as needed. Usually, new asphalt mixtures are controlled within 30% of the quality of recycled mixtures. The addition rate of various materials is determined based on the performance analysis of the original asphalt pavement and its laboratory mix design, and in accordance with the corresponding mixture specifications.
依據(jù)所使用的工藝可將現(xiàn)場熱再生細(xì)分為三種，即耙松整形再生、重鋪再生和復(fù)拌再生。
According to the process used, on-site thermal regeneration can be divided into three types, namely raking and shaping regeneration, re laying regeneration, and re mixing regeneration.
耙松整形再生：先用加熱設(shè)備把瀝青路面烤熱軟化，然后用設(shè)備本身自帶的耙松裝置將路面耙松整形，同時添加再生劑，然后用壓路機(jī)碾實 。
Raking and shaping regeneration: First, use heating equipment to heat and soften the asphalt pavement, and then use the equipment's own loosening device to loosen and shape the pavement. At the same time, add regeneration agent, and then use a roller to compact it.
重鋪再生：先用加熱設(shè)備把瀝青路面烤熱軟化，接著銑刨舊瀝青層，不同的是將銑刨下來的瀝青料直接進(jìn)行攤鋪，緊接著在其上面再攤鋪一層新的瀝青混合料，然后用壓路機(jī)碾實。
Re paving and regeneration: First, use heating equipment to heat and soften the asphalt pavement, then mill the old asphalt layer. The difference is that the milled asphalt material is directly spread, and then a new layer of asphalt mixture is laid on top of it, and then compacted with a roller.
、復(fù)拌再生：先用加熱設(shè)備把瀝青路面烤熱軟化，再用銑刨機(jī)銑刨舊瀝青層，然后按一定比例添加再生劑再添加用來調(diào)整集配的新料，攪拌后將混合料收集排放到攤鋪機(jī)上進(jìn)行攤鋪，最后用壓路機(jī)碾實。
Re mixing and regeneration: First, use heating equipment to heat and soften the asphalt pavement, then use a milling machine to mill the old asphalt layer, and then add a certain proportion of regeneration agent before adding new materials for adjusting the mixing. After mixing, collect and discharge the mixture onto the paver for paving, and finally use a roller to compact it.
