摘要
介绍了一种新的封层技术——同步碎石封层.与其他封层相比,同步碎石封层具有良好防水性能、独特的层间排水功能、高强的层间粘结力和抗剪力、良好的抗裂性和防路面反射裂缝功能、较低工程成本和延长路面使用寿命以及施工进度快等优点.阐述了同步碎石封层的材料组成及其主要材料的规格及技术指标要求,并探讨了此技术在我国公路建设中的应用.
Synchronized crushed stone seal new technology is introduced. Compared with other seals, the synchronized crushed stone seal has a good waterproof performance ： the unique function of interlayer draining water, strong force of interlayer cementing and resistance shear, a good resistance crack preventing the road surface reflection crack, the low project cost and prolong the pavement service life as well as quick construction progress. At the same time, the synchronized crushed stone seal material composition and its main material specification and technical index request are also elaborated. The technology application in highway construction of our country is discussed.
