瀝青混凝土施工，溫度就是生命線。從拌和到突出結(jié)束，溫度降一點，質(zhì)量就差一檔。

Temperature is the lifeline of asphalt concrete construction. From mixing to rolling, if the temperature drops a little, the quality will be one level worse.

拌和溫度。 瀝青加熱160-170℃，礦料175-190℃，混合料出廠155-170℃。溫度不夠拌不勻，溫度過高瀝青老化。

Mixing temperature. Asphalt is heated at 160-170 ℃, mineral aggregate is heated at 175-190 ℃, and the mixture leaves the factory at 155-170 ℃. Insufficient temperature results in uneven mixing, while excessive temperature leads to asphalt aging.

運輸保溫。 運輸全程覆蓋保溫，減少溫度離析。到現(xiàn)場溫度低于攤鋪要求直接退貨。

Transportation insulation. Cover the entire transportation process with insulation to reduce temperature segregation. Return directly if the on-site temperature is lower than the paving requirements.

攤鋪溫度。 普通瀝青混合料攤鋪不低于135-150℃。攤鋪機勻速行駛，不能忽快忽慢。

Spread temperature. The paving temperature of ordinary asphalt mixture shall not be lower than 135-150 ℃. The paver travels at a constant speed and cannot move too fast or too slow.

突出溫度是非常后的“生死線”。 初壓（攤鋪后立即進行）130-140℃，用雙鋼輪壓路機靜壓2遍。復(fù)壓不低于110℃。終壓不低于70℃——壓路機嚴禁在高于70℃的面上長時間停留。環(huán)境溫度低于5℃不得施工。

The crushing temperature is the final 'life and death line'. Initial compaction (immediately after paving) at 130-140 ℃, using a double drum roller to statically press twice. The re pressure shall not be lower than 110 ℃. The final pressure shall not be lower than 70 ℃ - the roller is strictly prohibited from staying on surfaces above 70 ℃ for a long time. Construction is not allowed when the ambient temperature is below 5 ℃.

壓實度怎么控？ 初壓后檢查平整度。突出從外側(cè)向內(nèi)側(cè)，彎道從低處向高處。溫度偏高瀝青會粘輪胎；溫度偏低壓不實。AC-13C、AC-20C路面空隙率均<6%。

How to control the compaction degree? Check the flatness after initial pressing. Crush from the outside to the inside, and bend from the low to the high. Asphalt will stick to tires when the temperature is too high; Low temperature and insufficient pressure. The void ratio of AC-13C and AC-20C road surfaces is both less than 6%.
