摘　　要：时代在不断发展,社会在持续进步,我国高速公路建设规模在持续扩大,很大程度促进了社会经济的可持续发展,与此同时也给人们日常出行带来了非常大的便利性。其中,高速公路桥梁建设过程中,桥面防水粘结层的施工质量如何,直接关系到后续运营期间的耐久性,所以必须要持续性地强化防水层的质量,最为有效的一项措施,就是运用重载沥青,其可以有效提高防水层的强度和可靠性,而且降低开裂和破损等一系列问题的发生概率,保证后续高速公路桥梁工程运行的安全性与可靠性,实现可持续发展。下面以凌绥高速公路为例进行相关的探讨。The times are constantly developing,society is constantly progressing,and the scale of China's highway construction is continuously expanding,which has greatly promoted the sustainable development of the social economy.At the same time,it has also brought great convenience to people's daily travel.Among them,the construction quality of the waterproof bonding layer on the bridge deck during the construction process of highway bridges directly affects the durability during subsequent operation.Therefore,it is necessary to continuously strengthen the quality of the waterproof layer.The most effective measure is to use heavy-duty asphalt,which can effectively improve the strength and reliability of the waterproof layer,reduce the probability of cracking and damage,and ensure the safety and reliability of subsequent highway bridge engineering operations,achieving sustainable development.The following discussion will take the Lingsui Expressway as an example.
